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.

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.

Their ability to take things out of the mailbox and catch things much faster than users is excellent.

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, 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.

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.

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.
