Automated threat detection that protects against corruption with minimal intervention
Abnormal Security is valuable because it features an automated scoring tool that doesn't require much intervention from our team. It enhances threat detection capabilities by making the process automated and is easy to scale to our entire environment. Additionally, it protects us from being business email compromised, which is invaluable for maintaining our security.
John Zupancic - PeerSpot reviewer
Pricing that is competitive, excellent technical support, and email security
They do a better job of distinguishing between what's real and what's not than most of the other solutions we've tried. They are very easy to use. We don't have as many problems with email security. They have some areas that could be improved. For example, we also use Zix email Encryption for email encryption, which was clunky and could be improved, but the email security itself has been excellent.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It does some really cool stuff that other tools aren't doing. We found it to be really effective, and the AI/ML functionality is really what differentiates them."
"Ease of use is undoubtedly one of the most valuable features of Abnormal Security."
"I like Abnormal's threat protection with auto-remediation, but I also love its abuse mailbox feature, which automatically responds to the end user. That feature has a super-valuable security component and helps improve the user experience."
"The features that appeal to me most are the combination of auto-remediation and Detection 360."
"One of the things that I love about them is that the setup and installation are super easy. All you do is give them access to your Microsoft 365 tenant, and through APIs, they are able to do their work. They are doing all this through APIs, so you do not have to install the software and take a month to get it all set up to even see the value of the solution. You could be up and running in less than an hour."
"I would recommend Abnormal Security."
"It protects us from being business email compromised, which is invaluable for maintaining our security."
"Their ability to take things out of the mailbox and catch things much faster than users is excellent."
"It's easy to use and user-friendly. Users can also easily release spam emails."
"They are very easy to use."
 

Cons

"The ideal scenario would be for Abnormal Security to work in tandem with Microsoft to analyze incoming emails."
"I would like to have the ability to customize the auto-remediation feature."
"The biggest pain point for us is the lack of support for on-premise email systems."
"There could be room for improvement in enhancing integration with other cybersecurity tools."
"One feature I'd love to see is outbound scanning."
"The pricing for academic institutions and student mailboxes is challenging."
"There could be more selectable options and more granular selections available."
"Abnormal should add more automatic reports. I have an open request to our account team for more notification and report types that can be sent automatically. For example, they have an awesome report that gets sent weekly, and I also want them monthly, so I don't need to do so much adding up when my director wants numbers over time."
"It needs to make sure that the application is up to date with new attacks. They should also send us the demo or introductions for their new incoming features."
"Email security checks contain a small number of false positives."
 

Pricing and Cost Advice

"The pricing appears fair, and they demonstrate a genuine willingness to work with us on it."
"The license is based on the user count, so the number of users that have an email address in the organization."
"Overall, we'd certainly prefer lower pricing, but Abnormal Security doesn't seem unreasonable compared to similar offerings in the market."
"Abnormal Security, on the other hand, provides the same level of functionality for just over $60,000 – that's half the price!"
"I can rate it five out of ten because there are different platforms that also offer the same services for lower prices. But AppRiver is more flexible."
"They're fairly inexpensive, but they're right in the ballpark of most of the other online products like that."
