}Frequently Asked Questions
Common questions about our SSL Certificate API.
An SSL (Secure Sockets Layer) certificate is a digital certificate that authenticates a website's identity and enables an encrypted connection. It's a critical component for securing online communication.
Monitoring ensures your websites remain secure and trusted by users. It helps prevent outages caused by expired certificates and protects against security vulnerabilities by flagging unexpected changes or weak configurations.
A Subject Alternative Name (SAN) is an extension to the SSL certificate that allows you to specify additional host names (sites, IP addresses, common names, etc.) to be protected by a single certificate.
