The FairSRS Score is a free security rating from 0 to 100 that measures a company’s externally observable security posture - the same outside-in signals a security team (or an attacker) can see without any access to the target’s internal systems. Enter any company domain above and FairSRS scans publicly available data to grade its third-party and vendor security risk in seconds, then generates a shareable report you can download as a PDF.
It’s powered by the free, open-source Fair TPRM platform and the same continuous security monitoring engine used inside our vendor risk management workflows - so the rating you see here is the same one security teams rely on to monitor their vendors.
Your FairSRS Score is a weighted blend of five externally observable security categories:
Each finding is a signal that adds or subtracts points, producing a 0-100 score and an A-F grade. To turn these signals into quantified financial risk, pair them with FAIR risk analysis and a full GRC compliance program.
Every domain below has a saved FairSRS Score you can open directly - no scan, no waiting, ranked highest score to lowest. Scores reflect the most recent scan and are re-checked when someone re-scans the domain.
Yes. FairSRS is completely free with no login, account, or credit card required. It is powered by the free, open-source Fair TPRM platform.
It measures a company’s externally observable security posture across five categories - TLS/cryptography, network security, application hardening, vulnerability (CVE) exposure, and email security - and combines them into a 0-100 score with an A-F grade.
FairSRS analyzes publicly observable data about a domain - open services, TLS and certificate configuration, security headers, known CVEs, and DNS-based email protections such as SPF, DKIM and DMARC - and weights each signal to produce the score. No login or access to the target is required.
Yes. No account is needed, and if you choose to have the report emailed, your address is used only to send that one report, encrypted in transit, then permanently deleted. We never store it, never sell or share it, and no one from Fair TPRM will contact you.
Yes. Enter any public company domain to check its external security posture. It is designed to help you assess third-party vendors and suppliers.
A security rating provides signals to help identify risk, but it is not a complete picture and should not be the sole basis for judging a company’s security. Some organizations run deception technology that can appear vulnerable but reflects a mature program. Always corroborate with direct assessment.
