Sophos Secure Message
Sophos Secure Message · Oxford, United Kingdom · founded 1985
What it is
Sophos Secure Message is part of Sophos Email, a cloud service for protecting inboxes from phishing, business email compromise, spam, and email-delivered malware. Detection combines AI and machine-learning models with natural-language processing, sender authentication, URL rewriting, and attachment sandboxing. Post-delivery protection can remove messages later identified as malicious. Secure Message policies can target users, groups, domains, and external recipients. Outbound encryption supports TLS, S/MIME, push encryption, and portal encryption. With portal encryption, recipients read and reply through a secure web portal without their own encryption infrastructure. Data-loss-prevention and content-control rules can detect sensitive information and encrypt messages automatically. Sophos Email integrates with Microsoft 365 and Google Workspace, supports Outlook, and connects telemetry with Sophos MDR and XDR. It runs on the web, offers password recipient verification and message expiry, and includes a free trial. Pricing is available on request.
