CertChief
What is CertChief?
About
CertChief is a certificate monitoring bot that periodically crawls web properties to check SSL/TLS certificate configurations, expiration dates, and security status. It reports problems and changes when they are detected to help maintain website security. You can see how often CertChief visits your website by setting up Dark Visitors agent analytics.
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.
