    Teams can choose an MX-based gateway or an API-based deployment. Gateway deployment routes incoming mail through Mimecast and provides routing controls and continuity. API deployment connects directly to supported cloud email services without changing MX records. The vendor supports Microsoft 365, Google Workspace, on-premises and hybrid environments through its deployment options.

    The wider product range includes DMARC Analyzer, email archiving, security awareness and managed threat response. Integrations with SIEM, XDR and security orchestration tools exchange intelligence and automate response. Plan and deployment choices are arranged through Mimecast’s sales process.

    Published email-security customer stories include Centrax and Abbot Point Operations.
