Provides comprehensive email security management, effective in detecting a wide range of email threats
The ideal scenario would be for Abnormal Security to work in tandem with Microsoft to analyze incoming emails. This means Abnormal Security would assess emails before they reach my inbox, even if it happens slightly after Microsoft's initial scan. Currently, the process isn't seamless. Microsoft analyzes emails and delivers legitimate ones to my inbox. Abnormal Security then scans these delivered emails, and if flagged as malicious, they disappear. This creates a problem for our ticketing system mailbox, which is a third-party service. Emails sent to the ticketing system address are automatically forwarded by Microsoft. However, if these emails are malicious, Abnormal Security only cleans them from my Outlook mailbox after they've been forwarded. Since we primarily rely on the ticketing system and not the Outlook mailbox, these malicious emails still reach the ticketing system.

I can't say that there is one specific feature that is most valuable. It's the overall platform that is well-suited to our needs. It's something that is different from a lot of other products or platforms in the marketplace. It provides a single console for security policy and management. That is somewhat important because we used to have other products where you would have to log in to individual appliances, devices, or clusters. Having one spot to log in to or one area to go to for doing different tasks and viewing data sources, just makes it easier from a user perspective. Also, the fact that it's invisible to our end-users and doesn't affect their work is very important. Most companies don't want to have added friction or impact on their users. In addition, the combination of user-friendliness for admins, and security for the organization, works well. As a cloud-hosted solution, it provides ease of use.

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."
"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."
"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."
"What I like about Abnormal Security is that it notifies me if any of my partners or suppliers are experiencing a security breach by analyzing their database and identifying potential cyber threats."
"It protects us from being business email compromised, which is invaluable for maintaining our security."
"I have never encountered any stability issues with Abnormal."
"I would recommend Abnormal Security."
"Their ability to take things out of the mailbox and catch things much faster than users is excellent."
"Menlo Security RBI's best feature is its threat isolation engine."
"I can't say that there is one specific feature that is most valuable. It's the overall platform that is well-suited to our needs. It's something that is different from a lot of other products or platforms in the marketplace."
 

Cons

"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."
"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."
"There could be more selectable options and more granular selections available."
"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."
"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."
"The pricing for academic institutions and student mailboxes is challenging."
"There are several features, such as supporting web technologies, that the company is working on implementing in the platform. There are a lot of backend web technologies in use on various websites, for example, two-way audio/video and WebGL, for which support may not be fully implemented in the product."
"Menlo Security RBI could be more cloud-friendly, and its mobility could be improved."
 

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."
"Abnormal Security, on the other hand, provides the same level of functionality for just over $60,000 – that's half the price!"
"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."
"Menlo Security RBI can be very costly."
