AI has helped classify threat types more accurately but product ownership can improve
Ease of use is important, and Abnormal Security's responsiveness and ability to deliver solutions when issues arise are crucial. However, there is always room for improvement, as achieving a perfect 10 means there is no more room for enhancement. For Abnormal Security, it's about leveraging AI even more, which they are already working on in their roadmap.

Offers clear vision on the clear side of what is being blocked and easy to use but a bit old-fashioned GUI
I would rate my experience with the initial setup a four out of ten when one is difficult, and ten is easy. It's difficult initially since it's an on-premise solution. So it's a bit difficult. So the initial assessment took a few days, and then the deployment was a couple of days. It is on-prem. That is also one of the improvements you need to make on the cloud. Most of the people like things to be on the cloud. You don't have the burden of setting up things on-premise.

Quotes from Members

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

Pros

"Initial auto-remediation allows us to auto-remediate before the email lands in the end user's inbox for a split second."
"The features that appeal to me most are the combination of auto-remediation and Detection 360."
"Their ability to take things out of the mailbox and catch things much faster than users is excellent."
"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 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."
"I would recommend Abnormal Security."
"I have never encountered any stability issues with Abnormal."
"Ease of use is undoubtedly one of the most valuable features of Abnormal Security."
"The product's most valuable features are spam protection and artificial intelligence."
"I like that it doesn't hold emails for any reason; it sends out notifications to the user as well as administrators. So we have a clear vision on the clear side of what is being blocked and in time as well."
 

Cons

"The ideal scenario would be for Abnormal Security to work in tandem with Microsoft to analyze incoming emails."
"There could be more selectable options and more granular selections available."
"I would like to have the ability to customize the auto-remediation feature."
"I, as such, do not have anything that I do not like or would like to add, but you could argue that because they are doing it API-based, there is a chance that something could slip through temporarily before they are able to pull it out. In theory, it could happen just because of the nature of the system. They are not in line with the delivery of the mail. They are kind of asynchronous, which is a pro as well as a con. If it is synchronous, then I know it would always stop them, but because it is asynchronous, things could get through temporarily or because of some system issues on the Microsoft side or their side. It is the nature of the beast, but it is a little bit of a con."
"The biggest pain point for us is the lack of support for on-premise email systems."
"One feature I'd love to see is outbound scanning."
"For Abnormal Security as a product, I would say probably somewhere around a seven, as there are some other areas where they can improve to achieve a higher rating."
"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."
"There is room for improvement in GUI because it is a bit old-fashioned."
"The technical support services and stability need improvement as well."
 

Pricing and Cost Advice

"Abnormal Security, on the other hand, provides the same level of functionality for just over $60,000 – that's half the price!"
"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."
"The pricing appears fair, and they demonstrate a genuine willingness to work with us on it."
"It is a cost-effective product."
"The pricing is in the middle. Compared to other products, it should be five out of ten, where one is cheap and ten is expensive."
