Frequently asked questions
What does the vendor security score measure?
The score evaluates a vendor's public website across multiple security domains: HTTP security headers (CSP, HSTS, X-Frame-Options, etc.), TLS/SSL configuration, DNS security records, and cookie attributes. Each domain receives a letter grade, and the overall score reflects the vendor's security posture relative to industry best practices.
Can I scan any website for a vendor assessment?
Yes, you can scan any publicly accessible website. The scanner analyzes the site's HTTP response headers, TLS certificate, DNS records, and page content. No access to the vendor's internal systems is required. This is a passive, non-intrusive scan of publicly available information.
How do I share scan results with my procurement team?
After scanning, you can generate a protected share link that anyone can view without an account. You can also export a PDF report that can be attached to vendor evaluation documents, RFP responses, or compliance files. Share links include an expiry date for security.
Is it legal to scan a third party website?
Yes. SiteSecurityScore performs a passive analysis of publicly available information, similar to visiting the website in a browser. It sends standard HTTP requests and analyzes the response headers, TLS certificate, and DNS records. No vulnerability exploitation or intrusive testing is performed.
