What is ProjectShield-UrlCheck?

About

ProjectShield-UrlCheck is a security scanner that monitors websites protected by Google's Project Shield service, checking for malicious traffic and DDoS attacks to ensure continuous protection. You can see how often ProjectShield-UrlCheck 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.
