What is TLS Certificate?

A TLS (SSL) certificate binds a domain name to a public key, verified by a trusted Certificate Authority (CA). When a browser connects to an HTTPS site, the server presents its certificate. The browser verifies the certificate chain, checks expiration, and confirms the domain matches. Certificate issues that cause security warnings include expiration, domain mismatch, untrusted CAs, self-signed certificates, and weak signature algorithms. Certificate monitoring ensures all certificates are valid and renewed before expiration.
