If you are an old Star Trek fan you know was a force field is! **What do you dislike about Barracuda Impersonation Protection?** This probably catches 85% of the bad email. I wish thia was ahigher, but honestly I do not know if that is actually achieavable becuass of the complexity of the threats, including AI infusion. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** It helps IT focus on other things becuase Baracuda's Impersonation Protection does a great job blocking day-to-day threats. ### 2. Useful Product, Great Features **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Law Practice | Mid-Market (51-1000 emp.) **Reviewed Date:** August 16, 2023 **What do you like best about Barracuda Impersonation Protection?** The dashboard and color coding the threats based on relevance. I did like the short snippets about what category the attacks fall under. **What do you dislike about Barracuda Impersonation Protection?** The reports aren't visually appealing. I would prefer to be able to create reports that I need specific details on. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** We are trying to solve the spam emails that user get. We have found that Barracuda is able to detect them and delete them. This leads to user being more productive and protected. ### 3. Excellent Coverage with Account Takeover Notifications **Rating:** 5.0/5.0 stars **Reviewed by:** Lorenzo L. | Associate IT, Enterprise (> 1000 emp.) **Reviewed Date:** February 17, 2026 **What do you like best about Barracuda Impersonation Protection?** The ability to receive account takeover notifications. **What do you dislike about Barracuda Impersonation Protection?** There is nothing I do not like, the product does an excellent job at offering coverage for impacted events. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** The additional coverage of takeover alerts. ### 4. Impersonation Protection that just works **Rating:** 5.0/5.0 stars **Reviewed by:** Jon L. | Director of I.T., Mid-Market (51-1000 emp.) **Reviewed Date:** August 08, 2023 **What do you like best about Barracuda Impersonation Protection?** It is always working and blocking potentially malicious emails. Instead of relying on our users to be trainined to avoid emails that are often dificult to determine are impersonating someone else; this system identifies the emails and deletes them before they even get to the users email. I have only seen 1 false positive in the past six months out of the ten to twenty emails that are blocked daily. TAhat one false positive was easy to resolve and allow through on the next pass. **What do you dislike about Barracuda Impersonation Protection?** Not so much a dislike of the system but of the volume of impersonated emails being blocked every day. I continue to review these to insure they are really impersonators. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** We train our users to be vigilant regrding spoofed emails and impersonators but this continues to get more and more complex. Bad actors are using other character sets and a variety of methods to get past the casual observer with look alike email addresses. Have a systematic approach reduces the potential for these emails to get through to our users for a negative result. ### 5. Our Experience using Barracuda Impersonation Protection for Higher Ed **Rating:** 4.5/5.0 stars **Reviewed by:** David G. | Security/Network Administrator, Mid-Market (51-1000 emp.) **Reviewed Date:** December 06, 2024 **What do you like best about Barracuda Impersonation Protection?** Barracuda Impersonation Protection has been a great purchase for our university. Previously, our faculty and staff were getting many spoofed emails..........and many of them appearing to come from C level executives, including President and CFO. Even though we mandate training, we still wanted a backup protection. Since implementing IP, the overwhelming majority of these spoofs get caught and the end user never sees them, other than an email notifaction that Barracuda had intercepted a rouge email. **What do you dislike about Barracuda Impersonation Protection?** There haven't been a lot of downsides to the platform............other than we have had several false positives. It is a platform that you want to keep a regular check on. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** The spoofed emails to our user base appearing to come from C level execurives...........including the President, CFO, COO, etc. We were having many of those get delivered before Barracuda, and even some users interacting with those emails. But we are seeing very little of those get delivered now that we have implemented Barracuda IP. ### 6. Generally Good **Rating:** 4.0/5.0 stars **Reviewed by:** Josiah D. | IT Administrator, Mid-Market (51-1000 emp.) **Reviewed Date:** December 05, 2024 **What do you like best about Barracuda Impersonation Protection?** - It appears to prevent a good deal of unwanted email from reaching our end users. - It removes the emails from user inboxes after identifying them as fraudulent. **What do you dislike about Barracuda Impersonation Protection?** - It is named "Impersonation Protection," but as far as I understand it, it also blocks general phishing attempts and scams as well. The name of the service leads one to the inference that it is more limited in scope than it actually is. - Also, with "Impersonation Protection" in mind, I want to note that it has in times past allowed fraudulent emails through which displayed our president's name, but was from a gmail address or other email domain that was not our own. I would have expected it to do better than that given that it should be able to see the names of people in our company and compare those to emails that pretend to be from people of the same name. I will say that this specific issue has not presented itself particularly recently, so it may have improved over time. - It does miss some emails that I really feel it ought to be capable of remediating. Things like some fake docusign emails or emails with "attachments" that are really just a picture of an attached file in the email. I think some of these are just using images to get around spam filtering which is an old and well-known technique in my mind. - I also tend to feel like some of the emails that it blocks should be getting filtered out by the "regular" Barracuda filtering and shouldn't need to be remediated by the Impersonation Protection service specifically. I can't be objective about it however. I just think some of the scam emails for example, should be detectable by the regualr spam filtering. - The process for reporting missed emails is fine, but I feel like those should be going to an email address that reflects the current product name, rather than the old "Sentinel" name. - I feel like there ought to be logs available which would show every email that Impersonation Protection has reviewed. I can only see which ones have been remediated. - It seems like many of the emails that get categorized as "impersonation" are really just spam, scam, or general phishing; not impersonation specifically. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** It remediates emails that the regular Barracuda spam filtering service missed, including phishing emails and scams. ### 7. in 6 months it has already stopped multiple account take-overs **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Mental Health Care | Mid-Market (51-1000 emp.) **Reviewed Date:** December 13, 2024 **What do you like best about Barracuda Impersonation Protection?** We have been using Barracuda Impersonation for 6 months, and the at-a-glance visibility it gives us into the state of our user's accounts is invaluable. Already it has stopped several account take over attempts, by alerting us when an account was being accessed from outside the country or when rules were being created for an account. The easy to use step-by-step account review has helped us verify nothing malicious has gone out of our user's accounts, and clamp down immediately when an alert goes off. We were able to set it up in 15 minutes and were up and running checking all our user's connectivity for the past month on the same day. Connecting it to M365 was a breeze, and it uses robust connection APIs. We use this every day. Barracuda support has always been just a phone call away, and they always have answers to all our communication questions. **What do you dislike about Barracuda Impersonation Protection?** It would be fantastic if it played a larger role within the M365 ecosystem. Micorosft has a larger ID Threat Protection platform, but it's cumbersome and difficult to get going, and requires advanced licensing. Barracuda gives us some of that functionality, but additional reporting like device compliance, or additional user Identity metrics would be extremely helpful. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** Visibility into account take over, alerts on suspicious activity, protects against phishing attacks. ### 8. Definitely functional, not convinced about usefullness. **Rating:** 3.0/5.0 stars **Reviewed by:** Jesse S. | System Administrator, Mid-Market (51-1000 emp.) **Reviewed Date:** December 05, 2024 **What do you like best about Barracuda Impersonation Protection?** It definitely works. It's dead simple to set up and another layer of protection that reduces the number of scams reaching inboxes. **What do you dislike about Barracuda Impersonation Protection?** There are a lot of false positives. I'm not entirely convinced of its usefulness **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** We've been using Impersonation Protection for about a month now. About 30% of the time we get false positives, typically when a user is forwarding something from their personal email to their work account which is somewhat annoying. That said, the service has prevented a good amount of fairly obvious scams that should be targeting HR (though typically aren't) trying to get the targeted user to change the direct deposit information of the person being impersonated. ### 9. Excellent job of blocking and filtering threats **Rating:** 5.0/5.0 stars **Reviewed by:** Garland V. | System Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** December 07, 2024 **What do you like best about Barracuda Impersonation Protection?** It's a powerful tool for any team, there are a lot features that we were able to leverage. I love the integration of all the products, it provides peace of mind and insight. It's the best solution for large companies. **What do you dislike about Barracuda Impersonation Protection?** It would be very help´ful if all reporting configuration was under a single interface, their admin system was a bit complicated to understand. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** It allows users to perform analysis and research, the product has a series of integrations with its entire platform. They offer easy-to-use tools to solve any threat, allowing us to take appropriate measures to mitigate risks. ### 10. Keeping us out of the headlines! **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Higher Education | Enterprise (> 1000 emp.) **Reviewed Date:** December 05, 2024 **What do you like best about Barracuda Impersonation Protection?** The Spear phishing protection parts of this alone has reduced the amount of time spent tackling email by drastic amounts and I use this every day. Use and administration is easy and the ability to gain information to further investigate the email is great. Support calls to Barracuda are always quickly answered, and has been great. We used support services for integration and it was aq uick and easy implementation. **What do you dislike about Barracuda Impersonation Protection?** I wish the account takeover parts had better information, however I understand that this is also at the mercy of Microsoft and 365 so it's still much better than what we had previously. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** We previously spent countless hours chasing down messages and purging them manually. This just works and reduced that to a minute fraction of the time (if any) spent doing that work. ### 11. Basically stopped impersonation emails **Rating:** 5.0/5.0 stars **Reviewed by:** Anthony R. | Systems Administrator, Mid-Market (51-1000 emp.) **Reviewed Date:** December 05, 2024 **What do you like best about Barracuda Impersonation Protection?** As a school district we were receiving many impersonation emails a month. users could not tell the difference sometimes. After we signed up for barracuda Impersonation Protection it pretty much stopped. Once and a while an email gets through but it's not a very good impersonation and users can tell the difference. **What do you dislike about Barracuda Impersonation Protection?** There is not anything dislike about it. I really like barracuda products. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** Stopping the phishing emails in which users were providing information like phone numbers, user names and passwords. ### 12. Works very well and good protection **Rating:** 4.0/5.0 stars **Reviewed by:** Abel A. | Network Administrator, Mid-Market (51-1000 emp.) **Reviewed Date:** December 06, 2024 **What do you like best about Barracuda Impersonation Protection?** it really drills down to which emails are being impersonated , where they are from , what email domain its coming from. It has a easy to use interface and it was very easy to implement. Customer support is outstanding for any issues we had. It easily integrates with our microsoft 365 enviroment and LDAP. We use very much often. **What do you dislike about Barracuda Impersonation Protection?** Alerts and intelligence. I also find that the information we see is not the same as customer support. it would be nice to see what they see as well. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** its solving the issue where emails come from imposters acting like internal leadership folks at the school and also staps scammers from acting and getting direct deposit info ### 13. Too many false positives based on algorithms, no real improvement **Rating:** 2.0/5.0 stars **Reviewed by:** Anthony G. | Systems Administrator, Mid-Market (51-1000 emp.) **Reviewed Date:** December 05, 2024 **What do you like best about Barracuda Impersonation Protection?** It is a decent high level security dashboard. **What do you dislike about Barracuda Impersonation Protection?** Tons of false positives massively over-weighting the sending address e.g. gmail, icloud, outlook.com are almost impossible to get delivered because they have a rep score of 0. We have had repeated issues where customers would email nothing more than a screenshot of our app or a photo of an invoice, as requested by agents, and they would be blocked/moved to Junk because of impersonation protection's "extremely high confidence" of phishing when in fact there is no real way to phish this way. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** It keeps in front of some basic phishing attempts. ### 14. New insights to Barracuda ESS **Rating:** 4.5/5.0 stars **Reviewed by:** Greg S. | Senior Network Administrator, Mid-Market (51-1000 emp.) **Reviewed Date:** July 24, 2024 **What do you like best about Barracuda Impersonation Protection?** Being able to view and remediate emails at a higher level that may otherwise be delivered to the end user is a stellar feature. I like the highlighting of potential issues in an email body, domain information (such as when a domain was registered), email flagging based on spam or conversation hijacking. We log into Impersonation Protection multiple times a day to review incoming emails. **What do you dislike about Barracuda Impersonation Protection?** There are times that emails get flagged that shouldn't. While remediation is easy, it seems that the learning is still a bit off. Where it is not preferred to whitelist any particular sender or domain, we do see from time to time the same emails getting flagged and marked as junk. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** Better visibility into incoming emails from outside the org. ### 15. A great product that has made security better **Rating:** 5.0/5.0 stars **Reviewed by:** Scott J. | Systems Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** December 05, 2024 **What do you like best about Barracuda Impersonation Protection?** The ability to automatically sort through logs and bring problems to our attention. **What do you dislike about Barracuda Impersonation Protection?** Nothing really. There are false positives but those are the ones where human interaction is able to determine that once we figure things out. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** Our SPAM protection, mail encryption, and security posture are all imporved with better details, more logical processing, and prompt alerting. ### 16.

You don't have to think about it. It has done thousands of emails, and we have only had two that we have had to pull back as false positives. They have got better reporting. **What do you dislike about Barracuda Impersonation Protection?** The price it is a little expensive. But you get what you pay for. More tuning options would be excellent but not necessary. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** Threatening emails of all sorts it pulls them from the inbox. ### 35. Good Phishing Protection Tool **Rating:** 3.5/5.0 stars **Reviewed by:** Ankit S. | Cyber Security Manager, Enterprise (> 1000 emp.) **Reviewed Date:** August 16, 2024 **What do you like best about Barracuda Impersonation Protection?** AI and Machine learning capabilities which detects suspicious email behaviour and patterns. Real time protection to catch the threat. Integration with mostly market leading tools like Microsoft and Google. **What do you dislike about Barracuda Impersonation Protection?** Little expensive as compared to other solutions.

Easy to setup, use and administrate **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Leisure, Travel & Tourism | Small-Business (50 or fewer emp.) **Reviewed Date:** August 30, 2024 **What do you like best about Barracuda Impersonation Protection?** The Barracuda Impersonation Protection system is fantastic. There is a bit of setup, but nothing that can't easily be accomplished and Support is FANTASTIC!! **What do you dislike about Barracuda Impersonation Protection?** I've not found any downsides to using this product. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** Keeping our email system clean and running the best that it can. ### 37. Reliable, clever M365 protection from account takeovers, UX management could do with an overhaul **Rating:** 3.5/5.0 stars **Reviewed by:** Harminder C. | Support Analyst, Computer Networking, Mid-Market (51-1000 emp.) **Reviewed Date:** September 07, 2023 **What do you like best about Barracuda Impersonation Protection?** I think the simplicity of it when its in place, it runs seamlessy behind the scenes linked by a global admin M365 account. There's no MX records to change or any other intrusive settings to edit, its pretty much plug and play. Alerts are also very clear and the steps to secure accounts are guided so any tech can use them. Reports sent monthly are a great feature and most clients love them, it makes auditing much easier and product renewal almost guaranteed. **What do you dislike about Barracuda Impersonation Protection?** The actual process of how Impersonation Protection is deployed is that downfall, especially from an MSP point of view. The initial setup is done by the legacy Echo platform which looks like it's still in 1998. Once you get to the main platform however, its much better but still lots of things in the wrong place so it make navigating a bit frustrating. If you could improve the whole backend UX that would really make it a perfect product. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** M365 on its is brilliant but the built in Anti-spam features are quite basic, unless you subscribe to the more expensive Defender solution you have a basic operation of anti-spam. Impersonation Protection uses AI to really crack down on unusual activity and foreign rules setup by an intruder/attacker. It's a great service and most clients want it because its cheaper than Microsoft's premium solution. ### 38. Very Handy if it fits your business case **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Financial Services | Mid-Market (51-1000 emp.) **Reviewed Date:** August 30, 2024 **What do you like best about Barracuda Impersonation Protection?** I like the amount of visibility I can have **What do you dislike about Barracuda Impersonation Protection?** I do not like the added cost of a single feature. Too lackluster to be sold singularly, and an advanced license is too pricy for a small-medium organization. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** Security ### 39.

For instance, its alert system, while informative, could benefit from more granular customization options to reduce false positives. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** Barracuda Impersonation Protection has been a game-changer for us, especially with the sneaky phishing attacks we've been seeing lately. Scammers will pretend to be high-ranking officials in the organization, these deceitful emails get caught before they can cause trouble.

Also for doing bulk actions multiple select doesn't allowing which is one of the big disadvantage. Little complicate to integrate the software while setting up. The frequency of use is more in our organisation so it will be good if the above things will be improved. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** It is very helpful for keeping safe from targeted phishing attacks,unwanted spam,malware and fradulent contents.

Brilliant to see something which helps to protect from Phishing / Fraud alerts **Rating:** 5.0/5.0 stars **Reviewed by:** Manish G. | Founding Member and Head of Business Operations, Education Management, Mid-Market (51-1000 emp.) **Reviewed Date:** September 28, 2023 **What do you like best about Barracuda Impersonation Protection?** I come up with this tool first time which has brilliant AI built technology. It understands the algoristhm and help to protect the user from fraud / phishing emails. In every organisation there is some fraud come-up with this and this is brilliant technology which fight against it and protect the users from the fruads so that they dont get into the trap. We had seen the number of features it has. Also its AI technology make this usniue. **What do you dislike about Barracuda Impersonation Protection?** I have never seen such type of product earlier. So this was the first time experience for me. When I got to know that there is some technology or tool which helps us from phishing email, I got too excited!! The support it provides, it is tremendous to see. They try to solve all the queries whichever raised by customer and make it smooth for the users. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** We faced with lot of phishing / fraud emails in our organisation which yields into big transaction of money. It leads to trap the employees, where they transfer the money by thinking that it was asked by their manager, seniors, directors, ceos, etc. Sometimes, same emails comes as a project where employee thinks that it would be great if they act on it. But it is like a trap for them. Its AI technology is madeup like that, which understand its domain, IP, etc and understand that it is not the true email. This helps the employees or organisation to get into the trap and solve the biggest problem related to high transactions of money, involvement of fake works / projects and time management. ### 44. Well worth your while. **Rating:** 5.0/5.0 stars **Reviewed by:** Mark N. | Mid-Market (51-1000 emp.) **Reviewed Date:** August 10, 2023 **What do you like best about Barracuda Impersonation Protection?** Barracuda Impersonation Protection has provided a sorely needed buffer to protect our most attacked and most vulnerable users, who are often one and the same.

It has been extremely effective in that role. ### 45. Review on Barracuda Impersonation Protection **Rating:** 4.5/5.0 stars **Reviewed by:** anushree v. | Assitant system engineer , Mid-Market (51-1000 emp.) **Reviewed Date:** October 11, 2023 **What do you like best about Barracuda Impersonation Protection?** Barracuda is an excellent software which detects malicious email sent and makes easy to remove it from the mailbox.

Dramatic cut back on impersonation attacks! **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Industrial Automation | Mid-Market (51-1000 emp.) **Reviewed Date:** August 08, 2023 **What do you like best about Barracuda Impersonation Protection?** The system was easy to set up and implement - taking less than an hour to ensure everything was configured correctly. Since that point, I get a regularly scheduled status report, along with email notifications on when the system is capturing impersonation attmepts. My team likes it because they can quickly report if they feel that a message is a false positive - in which we are able to go into the software and verify the message before resending it to the user. It has been a great addition and has captured on average about 10-20 messages per week from malicious sources pretending to be our CEO, accounting, or HR teams. **What do you dislike about Barracuda Impersonation Protection?** I'm struggling to find dislikes about it - the simplicity of the system, along with how easy it was to implement makes the software that much more robust, as there isn't a ton of rules or features you need to toggle on and off. It has nearly been a "set it and forget it" system that we rarely have to make any modifications to. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** We have dealt with a handful of situations prior to implementation where senders would often impersonate people on our team to try and get other team members to perform actions that are malicious in nature. While we have DMARC deployed on our systems, things still slip by and to the casual user, it may not be very apparent that the sender is not who they say they are. With Impersonation Protection, those instances are greatly reduced. Coupled with quarterly security training and simulated phishing tests, we feel we are in a great position having all of these items help educated and protect our team. ### 47. Save time on managing rules and custom management **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Manufacturing | Mid-Market (51-1000 emp.) **Reviewed Date:** August 08, 2023 **What do you like best about Barracuda Impersonation Protection?** When we moved from using our former email security we were up over 2000 rules in O365 to stop phishing and malware. Where the rules were extensive we were spending hours a day managing the email was was captured to determin if it was a valid email or not. With every week something new came out and we had to find a way to block it. With Barracuda the hours we spend each day evaporated and we can now manage our email environment in about 30 total minutes per day. **What do you dislike about Barracuda Impersonation Protection?** Only real cause for concern is if your business is travel based as the account takeover alerts will be slightly overwhelming. We had to add some geo location tools where we would not get alerted unless the user logged into the account from multiple areas of the country on the same day. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** ROI on the time spent to secure the email coming in and out of the organization. Not only does it allow us to use the time for other projects, but the reports give us a good overview of our current risk level and with that we can make additional changes to harden against any new threats. ### 48. Product just works. I don't have to worry about it **Rating:** 5.0/5.0 stars **Reviewed by:** Zachary L. | AVP IT and CISO, Mid-Market (51-1000 emp.) **Reviewed Date:** September 28, 2023 **What do you like best about Barracuda Impersonation Protection?** Imersonation Protection just works. Once setup, which was fairly easy since I already had other Barracuda products setup, it started detecting potential fraud attempts. It gives you a confidence level for likelihood of spam and details what kind of attack type is used. **What do you dislike about Barracuda Impersonation Protection?** Only stores the last 30 days of attacks. I'd like to be able to go back further in the event someone was compromised to track the initial breach. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** Stops spam and impersonation messages from even reaching the mailboxes of my users. ### 49. Ease of Use Proactive **Rating:** 4.5/5.0 stars **Reviewed by:** Nathan B. | Enterprise (> 1000 emp.) **Reviewed Date:** August 08, 2023 **What do you like best about Barracuda Impersonation Protection?** With Barracuda Impersonation Protection, I am able to efficiently eliminate any fraudulent emails from our email systems. Previous programs I have used did not compare to Barracuda's exceptional software. **What do you dislike about Barracuda Impersonation Protection?** Sometimes, I notice that the interface experiences some lag when attempting to delete a considerable number of emails. Nonetheless, the system eventually finishes the task, and we still have reliable protection. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** The function of preventing SPAM emails from infiltrating our system is crucial in maintaining its security. By swiftly removing such emails, we avoid the potential issues that may arise if a user responds to them.

Post Delivery Threat Elimination **Rating:** 5.0/5.0 stars **Reviewed by:** David W. | Network and Security Administrator, Mid-Market (51-1000 emp.) **Reviewed Date:** August 09, 2023 **What do you like best about Barracuda Impersonation Protection?** This tool constantly scans all emails in the inbox and when it finds one pretending to be an employee coming from someone else it yanks the message right out out of the inbox. **What do you dislike about Barracuda Impersonation Protection?** sometimes employee to employee email internally trips this and the email is yanked. While there is the ability to create exceptions to bypass this I would prefer a bit more fine tuning as I am not a fan of blindy skipping scanning. **What problems is Barracuda Impersonation Protection solving and how is that benefiting you?** This Helps to solve conversation hijacking and Direct Deposit redirection to scam accounts. The DD scam redirect has been on the rise and Cuda is at the fron line stopping these attacks. ## Barracuda Impersonation Protection Discussions - [What is Barracuda Impersonation Protection (formely Barracuda Sentinel) used for?](https://www.g2.com/discussions/what-is-barracuda-impersonation-protection-formely-barracuda-sentinel-used-for) - [What is Barracuda machine learning?](https://www.g2.com/discussions/what-is-barracuda-machine-learning) - [View Barracuda Impersonation Protection pricing details and edition comparison](https://www.g2.com/products/barracuda-impersonation-protection/reviews?section=pricing&secure%5Bexpires_at%5D=2026-05-19+01%3A13%3A52+-0500&secure%5Bsession_id%5D=e6efc187-5041-4ad2-a27d-2e58106f3fa4&secure%5Btoken%5D=766f546c88bb17efbbaced5a065aa8e21267885aeedab5e856a22f18f67efeda&format=llm_user) ## Barracuda Impersonation Protection Integrations - [Microsoft 365](https://www.g2.com/products/microsoft365/reviews) - [Microsoft Outlook](https://www.g2.com/products/microsoft-outlook/reviews) ## Barracuda Impersonation Protection Features **Administration** - Intelligence Reporting - Email Integration Suppor - Access Management - Data Loss Prevention **Administration** - Compliance - Intelligence Reporting - Email Clients - Role-Based Rules **Agentic AI - Email Anti-spam Features** - Autonomous Task Execution - Proactive Assistance **Maintenance** - Auditing - Allow and block lists - Compliance - Archiving **Detection** - Data Exfiltration Detection - Activity Monitoring - Real-Time Detection **Security** - Anti-Malware/Anti-Spam - Encryption - Quarantine - Advanced Threat Protection (ATP) - Anti-Phishing - Account takeover prevention **Protection** - Targeted Attack Prevention - Policy Enforcement - Spam Filtering **Agentic AI - Intelligent Email Protection** - Autonomous Task Execution - Adaptive Learning ## Top Barracuda Impersonation Protection Alternatives - [Microsoft Defender for Office 365](https://www.g2.com/products/microsoft-microsoft-defender-for-office-365/reviews) - 4.5/5.0 (277 reviews) - [Proofpoint Core Email Protection](https://www.g2.com/products/proofpoint-core-email-protection/reviews) - 4.6/5.0 (572 reviews) - [Valimail](https://www.g2.com/products/valimail/reviews) - 4.5/5.0 (459 reviews)
