A lean TLS configuration strips away wasted cycles, reduces attack surface, and delivers faster, safer connections. The goal is simple: maximize performance while meeting modern security standards. That means selecting protocols, ciphers, and settings with purpose, not habit.
Start with TLS 1.3. It’s faster, simpler, and removes legacy handshake steps. Drop TLS 1.0 and 1.1 completely. Keep TLS 1.2 only if you must serve older clients, and lock it down with strong cipher suites.
Enable only forward secrecy ciphers like TLS_AES_128_GCM_SHA256 or TLS_CHACHA20_POLY1305_SHA256. Cut weak algorithms, RSA key exchange, and CBC-based ciphers. This reduces exposure to known attacks and makes future breaches less harmful.
Disable renegotiation. Block compression. Set session resumption with tickets for speed, but control ticket lifetime to limit replay risks. Harden certificate settings with 2048-bit or stronger keys, short-lived certs, and automated rotation.
