The short version

  • Only Trivy has a free tier, so it costs nothing to try first.
  • Each has a real cost: Mimecast no pricing is published for any product or plan, and every route ends at a quote or demo request; Trivy reports what public advisory databases know, so coverage varies by ecosystem and unfixed CVEs create noise
  • They diverge on capability: Mimecast covers Advanced threat detection, Trivy covers Multi-target scanning.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Mimecast

  • No pricing is published for any product or plan, and every route ends at a quote or demo request
  • The platform is split into separately sold products for email security, awareness training, data protection and governance
  • Collaboration threat protection, DMARC analysis, incident response and email archiving are all further add ons on top of those

Trivy

  • Reports what public advisory databases know, so coverage varies by ecosystem and unfixed CVEs create noise
  • No built-in triage or exception workflow, so suppressing accepted risk is managed in config files
  • Findings are point-in-time from CI, with no continuous runtime monitoring unless you add the commercial platform
