Sophos Secure Message

What Sophos Secure Message is

Sophos Secure Message is part of Sophos Email, a cloud service that protects inboxes from phishing, business email compromise, spam, and email-delivered malware. It combines threat detection with controls for encrypted messages and sensitive data. Organizations can set policies for selected users, groups, domains, and external recipients; these policies govern access to secure incoming email. Outbound policies support TLS, S/MIME, push encryption, and portal encryption. With portal encryption, recipients can read and reply through a secure web portal without their own encryption infrastructure. Multi-rule data protection and content-control policies can detect sensitive email data and encrypt it automatically. Sophos Email uses AI and machine-learning models, natural-language processing, sender authentication, URL rewriting, and attachment sandboxing to detect threats. Post-delivery protection can retrieve messages later identified as malicious. The service integrates with Microsoft 365 and Google Workspace, supports Outlook integration, and connects threat telemetry with Sophos MDR and XDR. It runs on the web, offers a free trial, and has pricing on request. Secure Message policies cannot be configured in Monitoring System mode.
