Mimecast is an all round email security and resilience platform with threat protection, archiving and continuity, a long established choice for organisations wanting security plus email resilience and compliance. Founded in 2003, it protects email against phishing, BEC, malware and spam, and adds email resilience and continuity (keeping email available during outages), archiving for compliance and e-discovery, data protection, and security awareness training, as a comprehensive email platform. Long established and widely used, Mimecast suits organisations that want not just threat protection but also email continuity, archiving and compliance in one platform. For all round email security and resilience, Mimecast is a leading choice.
Mimecast's distinction is combining email security with resilience, archiving and compliance in one platform. Beyond blocking threats, it keeps email available during outages, archives for compliance and e-discovery, and adds data protection and training, so organisations get security and resilience together, which many value, especially for compliance. That combination of protection plus resilience and archiving sets it apart.
Mimecast is best for organisations that want email security together with resilience, continuity, archiving and compliance in one platform, including regulated organisations needing archiving and e-discovery. It suits all round email security and resilience. It is a weaker fit for teams wanting a pure AI native, API first advanced threat tool, where Abnormal fits, the simplest value SMB option, where Barracuda or Hornetsecurity fit, or Microsoft only shops relying on Defender for Office 365.
The core strengths are email threat protection (phishing, BEC, malware, spam), email resilience and continuity, archiving for compliance and e-discovery, data protection, and security awareness training, in one platform, with gateway and API options. Mimecast offers broad integrations and compliance features. Its combination of security, resilience, archiving and compliance is its defining advantage.
Mimecast is priced per user per month and quoted, varying by the capabilities chosen (security, continuity, archiving, awareness training), reflecting its breadth. Pricing suits organisations wanting security plus resilience and is negotiated. Costs scale with users and modules. Get details via the Mimecast site.
Mimecast integrates with Microsoft 365 and Google, the security stack (SIEM, SOAR), and archiving and e-discovery tools, with gateway and API options. Its integrations across security, archiving and the security stack, which let organisations unify protection, resilience and compliance, support its all round positioning.
Security plus resilience and archiving is the signature strength: Mimecast blocks email threats while also keeping email available during outages, archiving for compliance and e-discovery, and adding data protection and training, so organisations get protection and resilience together in one platform. For those wanting that combination, this is the main reason to choose Mimecast.
Mimecast is capable and comprehensive for email security and resilience, with good support, though reviewers note its breadth and administration take effort. Its G2 reviews praise protection, continuity and archiving, with complexity and cost the main considerations.
For organisations that want email security together with resilience, continuity, archiving and compliance in one platform, Mimecast is a capable, long established choice. The main caution is breadth and cost, so teams wanting a pure AI native advanced threat tool may prefer Abnormal, SMBs Barracuda or Hornetsecurity, and Microsoft only shops Defender for Office 365, but for all round email security and resilience Mimecast leads.
