What is SSL Labs?

SSL Labs is Qualys' free online SSL/TLS security testing service that performs deep analysis of SSL web server configurations on the public Internet to identify security vulnerabilities and grade SSL implementations.

Expected Behavior
Security scanners do not follow a predictable schedule when visiting websites. Their scans can be one-time, occasional, or recurring depending on the purpose of the scanner and the organization's security practices. The frequency and depth of their scans can vary based on factors like the visibility of the site on the public internet, past scan results, and inclusion in external threat intelligence feeds.
