Mesh 365 by Mesh Security is an API-based email security platform that enhances Microsoft 365 with advanced threat detection and response for email-borne attacks.

It supports MSP and enterprise use cases with cross-tenant visibility, centralized policy management, global block/allow rules, and one-click multi-tenant remediation. Features include sandboxing, URL protection, warning banners, and monitor-only deployment mode for safe evaluation. It reduces email security workload and improves response efficiency.
