Vendor Security Check

Enter a vendor's domain to check DNS, MX, SPF, and security headers. Get an instant risk score, then strengthen your vendor due diligence with our team.

Enter the vendor's domain (e.g. vendor.com). If you only have a company name, look up their main website domain first.

Disclaimer: This tool checks domain configuration (DNS, SPF, security headers) only. We do not report on company reputation or unverifiable breach data. For public breach history see haveibeenpwned.com or ICO.
