Mid-Market (51-1000 emp.) 8/8/2023 "Impersonation Protection that just works" 5/5 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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com.

Security/Network Administrator Mid-Market (51-1000 emp.) 12/6/2024 "Our Experience using Barracuda Impersonation Protection for Higher Ed" 4.5/5 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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com.

IT Administrator Mid-Market (51-1000 emp.) 12/5/2024 "Generally Good" 4/5 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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com.

System Administrator Mid-Market (51-1000 emp.) 12/5/2024 "Definitely functional, not convinced about usefullness." 3/5 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. Review collected by and hosted on G2.com. What do you dislike about Barracuda Impersonation Protection? There are a lot of false positives. I'm not entirely convinced of its usefulness Review collected by and hosted on G2.com. 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.

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. Review collected by and hosted on G2.com. What do you dislike 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. Review collected by and hosted on G2.com. 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. Review collected by and hosted on G2.com. 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.
