SSL (Secure Sockets Layer) and its successor TLS (Transport Layer Security) are cryptographic protocols that provide secure communication over the internet. SSL certificates are digital certificates that authenticate the identity of a website and enable encrypted connections between a web server and a browser. When a website has a valid SSL certificate, it uses HTTPS instead of HTTP, ensuring that data transmitted is encrypted and secure.
Regularly checking SSL certificates is crucial for website security and user trust. Expired or invalid certificates can cause security warnings, break HTTPS connections, and damage your website's reputation. Our free SSL checker tool helps you monitor certificate expiration dates, verify certificate validity, and ensure your website maintains secure connections.
Monitor certificate expiration dates to prevent security warnings and connection issues.
