Checks for the presence of a security.txt file at /.well-known/security.txt.
This check looks for a `security.txt` file at `/.well-known/security.txt` (RFC 9116). This file provides security researchers with contact information and guidelines for reporting vulnerabilities in your website.
Having a security.txt file makes it easy for security researchers to responsibly disclose vulnerabilities they find on your site. Without it, researchers may not know how to contact you, and vulnerabilities may go unreported or be disclosed publicly.
While not directly affecting SEO, security.txt demonstrates security maturity and can help you learn about and fix vulnerabilities before they're exploited. It's a low-effort, high-value security best practice.
