Tuta vs Egress
Tuta
Tuta (formerly Tutanota) is an open-source, end-to-end encrypted email provider based in Germany. Every email, contact, and calendar entry is encrypted at rest with zero-access architecture. Tuta uses its own encryption protocols rather than PGP, encrypting subject lines in addition to message bodies. While primarily focused on GDPR compliance and personal privacy, Tuta's business plans offer custom domains, team management, and whitelabel options.
Pros
- Fully open-source codebase
- Encrypts subject lines — not just bodies
- Affordable pricing for small teams
- German jurisdiction with strong privacy laws
- No tracking or advertising
Cons
- No HIPAA BAA available
- Custom encryption protocol (not PGP/S/MIME)
- Limited enterprise admin features
- Fewer integrations than established platforms
- No bridge app for third-party mail clients
Pricing: From $8/user/month (Business)
Egress
Egress provides intelligent email security that combines adaptive encryption with AI-powered risk detection. Rather than applying blanket encryption rules, Egress analyzes each email's content, recipients, and context to dynamically determine the right level of protection — from automatic TLS to full end-to-end encryption. Now part of KnowBe4, Egress signs BAAs for HIPAA compliance and is widely used in healthcare, legal, and financial services.
Pros
- Intelligent risk-based encryption reduces over-encryption
- Prevents misdirected emails before they send
- Strong Outlook and Microsoft 365 integration
- Reduces user friction with adaptive policies
- Comprehensive compliance reporting
Cons
- More complex to configure than simpler solutions
- Primarily Microsoft-focused ecosystem
- Pricing not transparent
- KnowBe4 acquisition may shift product direction
