Mimecast

Mimecast is a leading cloud-based email security and cyber resilience company, purpose-built to help organizations protect against the most common and damaging attack vector in modern cybercrime: email. Founded in 2003 and headquartered in London, United Kingdom, Mimecast serves more than 40,000 customers worldwide across a broad range of industries, with particular strength in financial services, legal, healthcare, and professional services sectors.

Mimecast Email Security Cloud Gateway provides comprehensive protection for Microsoft Exchange, Microsoft 365, and Google Workspace environments. The platform analyzes 100 percent of inbound and outbound email traffic for malicious attachments, dangerous URLs, impersonation attempts, and spam, combining signature-based detection with AI-powered behavioral analysis and threat intelligence to stop both known and unknown threats before they reach users' inboxes.

Mimecast's Targeted Threat Protection is a suite of advanced security capabilities that specifically addresses sophisticated, targeted attacks. URL Protect rewrites all links in inbound email and performs real-time safety checks when users click them, blocking malicious destinations even after emails have been delivered. Attachment Protect safely sandboxes suspicious file attachments before converting them to clean versions for delivery. Impersonation Protect uses machine learning to detect fraudulent emails that attempt to impersonate executives, trusted suppliers, or government agencies.

Mimecast Email Archive provides a compliant, scalable cloud archive for all email communication, with 10-year retention, tamper-proof storage, and fast search capabilities that support legal hold, compliance audits, and e-discovery requirements. The archive integrates seamlessly with Microsoft Outlook, enabling employees to access archived messages without leaving their familiar email client.

Mimecast Business Email Continuity ensures uninterrupted email access during planned or unplanned Microsoft 365 outages. By maintaining a continuously synchronized emergency inbox in the cloud, Mimecast allows users to continue sending and receiving email even when their primary email platform is unavailable. Mimecast's DMARC Analyzer helps organizations implement and monitor email authentication standards to prevent domain spoofing and protect their brand from being weaponized in phishing campaigns.
