6. KnowBe4 Cloud Email Security

By KnowBe4

4.7

(415 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.Read all insights and reviews for KnowBe4 Cloud Email Security

7. Darktrace / EMAIL

By Darktrace

4.8

(405 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. Read all insights and reviews for Darktrace / EMAIL
