4. KnowBe4 Cloud Email Security

By KnowBe4

4.7

(447 Ratings)

The Knowbe4 Cloud Email Security, aka Knowbe4 Defend, in relation to Microsoft 365 - has a lot of setup involved, but luckily its almost all automated with a script that KB4 pre-built to connect the services in your Azure environment. The deployment team and the engineer we had ere very good, communicated well and timely, and the engineer knew how to fix certain pain points, which were mainly just customization options that we were choosing to enforce outside the regular deployment plan the provided to us. Once it was up and running, like any other AI tool, it takes time to learn your environment and then fine tune its detections. The dashboards and email notifications are exceptional.

5. Abnormal Behavior Platform

By Abnormal AI

4.8

(446 Ratings)

We started looking into Abnormal to replace a more traditional email gateway solution that we had in place. We were spending a lot of time constantly maintaining block lists and sorting through false positives. We were spending a lot of time trying to tweak things to protect against incoming threats, only to have attackers switch tactics and eventually get through. It was a constant cat and mouse game, and we felt we were always behind. When we first deployed Abnormal and ran through a POC, we layered it on top of our existing solution. It was both impressive but also alarming as we quickly discovered the volume and extent of just what was coming through our traditional solution. Abnormal from the time we started the POC to full implementation Abnormal has just worked. I was amazed at just how easy it was to setup and configure as well as just how effective it's been. Abnormal has been truly transformative not only for my team, but our business as a whole.

6. Darktrace / EMAIL

By Darktrace

4.8

(407 Ratings)

We have been using Darktrace for just about 2 months now, the platform has been brilliant so far and it was picking up things that our old provider was missing. We have a team of people from Darktrace that are helping us with training, issues and questions and so far they have been able to resolve everything. Our users haven't complained about the new service and it's now protecting the company more with the identity module and the dmarc module as well which all tie in together to fully protect the company. The platform itself is brilliant and so easy to use, the mobile app is one of the features that made us go with Darktrace as you can remediate issues straight away if needed as the AI will automatically block or lock users out if it thinks their account is doing something it doesn't usually do etc.
