IT Mid-Market (51-1000 emp.) 8/24/2021 "A necessary tool to protect your domain from malicious entities on the internet" 5/5 What do you like best about Barracuda Impersonation Protection? Sentinel has been a lifesaver! In the past, when an incident concerning a malicious email hits my service board, it was very time-consuming and next to impossible to track and mitigate. This arm of the Barracuda platform eliminates all of the guesswork. I can see who received the message and pull the email from everyone's inbox with a few clicks. Also: the ability to have it auto-remediate is enormous! Peace of mind is a priceless thing. Now that I've been using it for over a year I can't imagine email security any other way. Review collected by and hosted on G2.com. What do you dislike about Barracuda Impersonation Protection? There is nothing about this product that I dislike. Everything about it works very well. However, the barrier to entry for Barracuda's email security services does require going through an MSP, and MSPs have minimum requirements to make it "worth it." The size of an organization shouldn't be a barrier to access a necessary product like this. I would love to see Barracuda have an offering for smaller organizations (1 - 25 users) where they can get the same grade of security as larger organizations. Review collected by and hosted on G2.com. Recommendations to others considering Barracuda Impersonation Protection: You won't be disappointed going with Barracuda Sentinel. Review collected by and hosted on G2.com. What problems is Barracuda Impersonation Protection solving and how is that benefiting you? For years tackling email security matters has been difficult. Even with spam filtering services, things always get through. And after that, if you want insights, auto-remediation, advanced detection? Forget about it! Could someone build a solution? Yeah, sure, maintaining it is a Sisyphean task. Barracuda already has a solution it's called Sentinel. You get all the benefits of an advanced detection and remediation system without having to build and maintain it. What would take hours and days to handle can be done in a matter of seconds.

Barracuda Sentinel is easy to configure and put in place with other Barracuda Security products (example, Barracuda Essentials). Clear emails to the end-user warning them about the phishing attempt. Review collected by and hosted on G2.com. What do you dislike about Barracuda Impersonation Protection? Reporting missed phishing attacks back to the Barracuda Sentinel team requires that we find the email in Barracuda Essentials, download it, and email it to the Sentinel Security Team. I'm hoping Barracuda can better integrate their products and reporting. Review collected by and hosted on G2.com. What problems is Barracuda Impersonation Protection solving and how is that benefiting you? Barracuda Sentinel adds another layer of security to our email filtering. Currently, we are using Barracuda Sentinel in combination with Barracuda Essentials and Microsoft's tools for email filtering. Adding that extra layer of security that scans our email for its contents and spots malicious phishing attempts. Review collected by and hosted on G2.com.

Director of IT Mid-Market (51-1000 emp.) 6/2/2020 "First Week Using - Identified an Account Takeover" 5/5 What do you like best about Barracuda Impersonation Protection? It's easy to use, gives you the opportunity to refine searches, and is very fast. We can immediately block the email address or domain of the sender, and also set up continuous remediation, if needed. Review collected by and hosted on G2.com. What do you dislike about Barracuda Impersonation Protection? It keeps a history log of all the spear phishing attacks. This log cannot be deleted or trimmed down and becomes quite large after a while. I would like to be able to purge information out of the log. Review collected by and hosted on G2.com. What problems is Barracuda Impersonation Protection solving and how is that benefiting you? Within the first week of use it identified an account takeover from someone in Turkey, which we easily stopped! We have been able to be notified of spear phishing attacks immediately when they happen. We can identify the attack, find out if it proliferated to other users, and then remediate the attack within minutes! This would have taken us hours before. Review collected by and hosted on G2.com.

The AI element, auto response to potential threats. When a suspicious login is detected from an unusual place is great, highlighting when users have inadvertently given login details away.
