Transport Layer Security
SinglePoint enforces 256-bit TLS for every connection from the user browser or mobile app to the edge load balancers that front the portal. TLS 1.2 is the minimum accepted version; TLS 1.3 is negotiated when the client supports it. Cipher suites are restricted to those with perfect forward secrecy so that a later compromise of long-term keys cannot decrypt historical sessions. HTTP Strict Transport Security headers force browsers to prefer encrypted connections for every subsequent visit. Certificates are issued by a publicly trusted certificate authority and rotated on a documented schedule that predates the RSA or ECDSA key lifetime limits recommended by the Federal Reserve and NIST guidance for commercial banking systems.
