What is an SSL Certificate?
An SSL certificate encrypts data between a visitor’s browser and your website, keeping sensitive information safe. Websites with SSL use HTTPS, which is a trust signal for users and search engines.
Our SSL Certificate Checker verifies if a site has a valid certificate, whether it’s correctly installed, and if your connection is secure.
