Encryption in Transit Overview
Encryption in transit protects data during transmission preventing eavesdropping, man-in-the-middle attacks, and tampering. TLS/SSL is standard for web traffic with additional protocols for specific use cases.

TLS Implementation
Implement TLS 1.2 minimum (prefer TLS 1.3), use strong cipher suites with forward secrecy, configure proper certificate validation, implement certificate pinning for critical connections, and enable HSTS forcing HTTPS.
VPN Encryption
VPN encryption protects network communications using IPSec with strong algorithms, SSL/TLS VPN, or modern solutions like WireGuard. Configure proper authentication, perfect forward secrecy, and split-tunneling carefully.
Email Encryption
Protect email using opportunistic TLS for transport, S/MIME or PGP for end-to-end encryption, and secure email gateways. Understand that standard email encryption doesn't protect subject lines or metadata.
Application Protocols
Encrypt application protocols through TLS wrapping (HTTPS, FTPS, LDAPS), protocol-native encryption (SSH), or application-level encryption. Ensure encryption covers all sensitive communication channels.
