Mimecast Advanced Email Security review

Mimecast suits organizations whose mail is not purely in the cloud. It protects Microsoft 365, Google Workspace and on-premises or hybrid environments, and you can deploy it as an MX-based gateway that blocks bad mail in line or without a gateway. Detection combines anomaly detection based on social graphing, sandboxing to catch evasive files, on-click link protection and computer vision that spots brand and login page impersonation. Contextual banners warn users in the message and support remediation of threats such as QR code phishing and BEC. The platform connects to SIEM and XDR tools for shared threat intelligence, and adds Mimecast's own Continuity, DMARC, security awareness training and Archiving modules, so one vendor can cover filtering, outage access and retention. Mimecast says 42,000 customers use it. The downsides are a quote-only model, more setup for gateway deployments and a larger set of modules to manage. If your estate is hybrid or you want archiving and continuity with your filter, it is a sound choice; cloud-only teams can get faster results from API tools.
