About
Mimecast is a comprehensive human risk management and advanced email security platform designed to protect organizations from sophisticated cyber threats in the age of AI. The platform unifies multiple security disciplines — from email and collaboration threat protection to insider risk management, data governance, compliance, and security behavior management — into a single, cohesive solution. At its core, Mimecast uses AI-powered detection backed by decades of threat intelligence to identify and neutralize threats like phishing, business email compromise (BEC), and shadow AI risks before they cause damage. Its Incydr product addresses insider threats, while the Aware Governance & Compliance Suite enables real-time data insights for regulatory adherence. The Engage module re-envisions security awareness training by leveraging human risk signals to drive lasting behavior change. A standout capability is Agentic AI Security, which helps organizations discover, govern, and secure AI agents operating within their environment — reducing shadow AI usage by up to 30%. Mimecast also offers DMARC Analyzer for brand protection, Email Archive for compliance and eDiscovery, and a robust API platform for MSPs and technology alliance partners. Mimecast is purpose-built for enterprise and mid-market organizations across legal, compliance, IT security, and HR functions. With 42,000+ customers worldwide and recognition as a Gartner Magic Quadrant Leader, it is a trusted choice for organizations seeking to reduce human-driven cyber risk at scale.
