An SSL Certificate Checker allows you to audit and verify the installation of SSL/TLS certificates on any web server. Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are security protocols that establish an encrypted link between a web server and a browser. This ensures that all data transmitted remains private and integral, protecting user credentials, payment details, and personal communications from eavesdropping.
Using an SSL auditor helps administrators identify expired certificates, insecure signature algorithms, weak cipher suites, and hostname mismatches. Modern search engines and browsers flag sites without valid HTTPS/SSL as insecure, which negatively affects search engine visibility and user trust. Regularly inspecting SSL details like issuer chain, validity period, and protocol support ensures robust cybersecurity hygiene.
