About SSL/TLS Certificates: SSL/TLS certificates secure communication between browsers and servers. Server Check uses a backend API to retrieve full certificate details including chain, validity, and PEM downloads. Browser Check tests reachability directly from your browser — useful when the backend cannot reach the target (e.g., internal or restricted domains).
