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

"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."
"Ease of use is undoubtedly one of the most valuable features of Abnormal Security."
"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."
"Abnormal Security's AI capabilities are what we like most, as they can categorize and classify the emails, and based on the context of the email, understand if it's a graymail, a bulk mail, or a phish."
"I would recommend Abnormal Security."
"Initial auto-remediation allows us to auto-remediate before the email lands in the end user's inbox for a split second."
"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."
"They are very easy to use."
"It's easy to use and user-friendly. Users can also easily release spam emails."
 

Cons

"One feature I'd love to see is outbound scanning."
"There could be room for improvement in enhancing integration with other cybersecurity tools."
"When we're working on something as engineers, and we find an idea or a method of doing something that would be greatly improved by doing it another way, there should be an ability for me to click the ideas button, type in an idea that I have, and submit it to a product review team or developers to have them think through the process a little bit more."
"There could be more selectable options and more granular selections available."
"There could be more selectable options and more granular selections available."
"The pricing for academic institutions and student mailboxes is challenging."
"The biggest pain point for us is the lack of support for on-premise email systems."
"I would like to have the ability to customize the auto-remediation feature."
"Email security checks contain a small number of false positives."
"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."
 

Pricing and Cost Advice

"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!"
"The pricing appears fair, and they demonstrate a genuine willingness to work with us on it."
"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."
