What it does
Echoworx is an organizational email-encryption layer with policy-based routing. It documents S/MIME, PGP, TLS, portal and encrypted-document delivery, plus automated key and certificate management.
Echoworx chooses a protection route around organizational policy and recipient capability. Its documentation lists certificate-based encryption, TLS, a web portal and encrypted documents rather than one delivery method for every contact.
The platform integrates through SMTP routing with existing mail and inspection systems. That architecture makes gateway placement and key management central decisions. The documentation also explains inbound decryption using keys stored within the platform, so it should not be described as a system where every provider component is unable to decrypt every message. It is a governed encryption layer for an organization’s mail flow.
Strengths
- Several standard and portal-based delivery methods are documented.
- Policy evaluation can select a route for the recipient.
- Key and certificate management can be automated.
Best for
