Mailprotector vs MX Guarddog

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.

MX Guarddog is a hosted email gateway for standard SMTP servers serving owned domains. It scans incoming messages for spam, phishing, malware and viruses, quarantines offending mail, and forwards clean messages to the customer’s server. The service runs in the cloud, so it requires no hardware or software installation and no configuration changes to email clients or the server. Quarantine reports summarize stopped spam, and users can adjust report preferences; quarantine retention is seven days. If a customer’s server is unavailable, MX Guarddog says it holds mail for up to 168 hours and delivers it when the server returns. It can sync active addresses from Windows AD, LDAP or cPanel, and says it uses Transport Layer Security, including Perfect Forward Security, for email in transit. The listed per-address price is $0.25 per month; aliases are not charged. A free plan and 30-day trial are listed. The service is for web use and does not support consumer Gmail or Hotmail accounts.
