Our take
Cisco shops wanting Talos-backed filtering.
It is on the list as a Microsoft 365 product that can grow with you: you start in API mode and add the inline gateway later, from the same console. That suits a team that already runs Cisco security. Check fit first if you run Google Workspace or your own mail servers, because the product is built for Microsoft 365.
