Email Security Reviews 2023 | Gartner Peer Insights

We only started using Defender recently (since the start of 2022) but it has already detected advanced phishing attempts that our SEG missed and therefore helped reduce our risk.
In addition, the ability to take action on phishing emails across multiple inboxes is saving our team serious amounts of time and serves to reduce our risk even further. We are excited to utilise the O365 API integration once our environment is setup so we will be able to automatically quarantine phishing emails before ever reaching the user’s inbox. Tessian Defender forms a key part of our email security strategy as our business moves away from the traditional SEG and more toward Exchange Online Protection.
