Email Encryption Tools FAQ
Common questions about Email Encryption tools, selection guides, pricing, and comparisons.
Gateway-based email encryption is the easiest to deploy: it sits between your mail server and the internet, automatically encrypting emails based on policy rules (containing sensitive data, going to specific domains). Recipients access encrypted emails via a secure portal or PDF. This requires no client-side setup, unlike S/MIME or PGP which need certificate management on every endpoint.
