SecurityScorecard

Primary category: vendor-risk.

One-liner — An outside-in security-ratings service that scores companies (and their vendors) A–F on externally observable cyber posture, used to triage third-party risk.

What it does — SecurityScorecard continuously scans the internet for signals (patching cadence, exposed services, DNS/email hygiene, leaked credentials, malware chatter) and rolls them into a letter-grade rating per organization. Buyers use it to screen and monitor suppliers without sending questionnaires, and to benchmark their own posture. Increasingly bundles supply-chain detection and, via the 2025 HyperComply buy, AI-driven security-questionnaire automation.

Where it sits in the stackvendor-risk, governance layer. An external risk-signal source feeding TPRM decisions — not a runtime data control or inline prompt/egress control. Complements assessment-workflow platforms like processunity and onetrust; a direct peer of bitsight, black-kite, upguard.

Deployment & architecture — SaaS. Outside-in scanning + ratings API/portal; integrations with GRC/TPRM and security tooling; questionnaire automation (post-HyperComply).

Positioning & differentiators — One of the two best-known ratings brands alongside bitsight. Differentiators are breadth of scanned signals and a marketplace/ecosystem play; like all ratings, accuracy/attribution of external signals is the perennial critique. The HyperComply acquisition pushes it toward “ratings + automated assessments.”

Ownership, funding & M&Aindependent, private, VC/growth-backed. Founded 2013 (Aleksandr Yampolskiy, Sam Kassoumeh); HQ New York. ~$290M+ raised; Series E $180M (2021) at ~$1B valuation; investors include Silver Lake, Sequoia, GV, Evolution Equity. Itself an acquirer: bought HyperComply (2025-09-15) for AI questionnaire automation. No acquisition of SecurityScorecard found. (high confidence)

CTO / hedge-fund lens — Day-1-ish for a fund standing up third-party risk: a low-effort way to screen and monitor vendors (including AI/SaaS suppliers) by external posture. Best used alongside an assessment workflow rather than as the sole control; external ratings are a triage signal, not ground truth.

Competitors / alternativesbitsight, black-kite, upguard, processunity, onetrust.
