What SecurityScorecard does well

SecurityScorecard is one of the most recognized names in cyber risk ratings. They provide continuous monitoring, letter-grade security ratings (A-F), and a large vendor ecosystem. For enterprise security teams that need a quick risk signal across thousands of vendors, SecurityScorecard's rating system provides a standardized benchmark. Their platform is mature, well-funded, and widely adopted by Fortune 500 companies.

Where cyber ratings fall short for compliance teams

A security rating tells you one thing: an outside-in estimate of cyber hygiene. It doesn't tell you whether a vendor is on a sanctions list, whether their business registration is legitimate, whether they've been the subject of regulatory enforcement actions, or whether their compliance certifications can be independently verified. For SOC 2 CC9.2, HIPAA, or PCI-DSS vendor due diligence, a letter grade alone isn't sufficient audit evidence.

ThirdProof's approach: full-spectrum vendor intelligence

ThirdProof queries 27 intelligence sources covering sanctions screening (OFAC, EU, UN), business registration verification, adverse media, cyber risk analysis, certification verification against independent registries, SEC filings, FDIC records, and subprocessor supply chain discovery. Every finding cites its source. The methodology is public and deterministic — the same data always produces the same risk tier.

Cost: per-report vs. annual contract

SecurityScorecard pricing starts around $25,000/year and can exceed $100,000+ for enterprise tiers with full API access and portfolio monitoring. ThirdProof is $399/month for unlimited investigations — no annual commitment, no per-vendor fees, no enterprise sales cycle. For mid-market teams that need vendor due diligence without a six-figure budget, the cost difference is significant.

Common questions

Can ThirdProof replace SecurityScorecard?+
It depends on what you need. If your primary requirement is continuous cyber risk monitoring with letter-grade ratings across a large vendor portfolio, SecurityScorecard is purpose-built for that. If you need comprehensive vendor due diligence for compliance frameworks — covering sanctions, business legitimacy, compliance verification, and cyber risk with audit-ready documentation — ThirdProof provides broader coverage at a fraction of the cost.
How does ThirdProof's methodology compare to SecurityScorecard's ratings?+
SecurityScorecard uses a proprietary algorithm to generate A-F letter grades based on outside-in cyber signals. ThirdProof uses a deterministic rules engine — the same data always produces the same risk tier, and the methodology is publicly documented. Every finding cites its exact source so your auditor can verify independently.
Is SecurityScorecard's pricing worth it for a mid-market company?+
At $25,000-$100,000+ per year, SecurityScorecard is priced for enterprise security teams with large budgets. For mid-market compliance teams that need vendor due diligence documentation, ThirdProof delivers broader risk coverage (sanctions, compliance, business legitimacy, and cyber) at $399/month.
Does ThirdProof provide continuous monitoring like SecurityScorecard?+
ThirdProof currently provides point-in-time assessments — deep, comprehensive vendor investigations that produce audit-ready documentation. SecurityScorecard provides continuous monitoring of cyber risk signals. For most compliance frameworks, periodic point-in-time assessments satisfy the vendor due diligence requirement. Teams that need both often use ThirdProof for compliance assessments and a monitoring tool for ongoing alerting on critical vendors.
