The short version

  • Each has a real cost: Fortinet FortiGate security services are sold as separate FortiGuard subscription bundles, so ATP, UTP and ENT determine which protections are actually active; Mimecast no pricing is published for any product or plan, and every route ends at a quote or demo request
  • They diverge on capability: Fortinet FortiGate covers Next-generation firewall, Mimecast covers Advanced threat detection.
  • Prices and features above were last checked on 30 August 2026.
