Mailprotector vs Sophos Secure Message

Mailprotector makes email security and management products exclusively for managed service providers. Shield combines a secure email gateway with an API integration for Microsoft 365 environments; the company says Google Workspace support is on the horizon. CloudFilter filters email where customers control MX records, including Microsoft 365, Google Workspace, on-premises servers, hosted environments and POP/IMAP. Bracket encrypts messages when a subject contains square brackets, without requiring apps, plugins or passwords from senders or recipients. It uses AES-256, and its one-time sign-in links expire after 15 minutes or become invalid if opened from another device. SecureStore captures messages going forward and has a seven-year default retention period, which can be adjusted. Mailprotector states that it holds the HIPAA Seal of Compliance from Compliancy Group and is SOC 2 Type 2 certified. ConnectWise, Autotask and Gradient integrations support licensing or service-count synchronization and billing workflows, and are free. Radar is a free email security check; current product pricing is available from an account manager.

Sophos Secure Message is part of Sophos Email, a cloud service for protecting inboxes from phishing, business email compromise, spam, and email-delivered malware. 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 after they reach inboxes. Organizations can set Secure Message policies for selected users, groups, domains, and external recipients. Outbound policies support TLS, S/MIME, push encryption, and portal encryption. With portal encryption, recipients can read and reply to encrypted messages through a secure web portal without maintaining their own encryption infrastructure. Multi-rule data-protection and content-control policies can detect sensitive email data and encrypt it automatically. Sophos Email integrates with Microsoft 365 and Google Workspace and connects threat telemetry with Sophos MDR and XDR. Secure Message policies cannot be configured in Sophos Email Monitoring System mode. A free trial is available through an active Sophos Fusion account or the trial form. Pricing is on request, and there is no free plan.
