SecurityHeaders

What is SecurityHeaders?

About

SecurityHeaders is a free security scanning service that analyzes HTTP security headers on websites, providing grades and recommendations to improve web security posture and protect against common vulnerabilities. You can see how often SecurityHeaders 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.
