External attack surface management and external vulnerability scanning find what attackers can see from the internet. Third-party risk management applies the same view to your vendors.
My pickRoot EvidenceVulnerability management with external attack surface discovery (Root Evidence).
Vulnerability scanners test the assets you already know about, while EASM discovers the ones you don't. Security ratings products score you and your vendors from the outside. Compare discovery accuracy, false-positive rates, and whether the findings map to what insurers scan for.
Why it works
Insurers scan applicants from the outside before they quote. Exposed remote access, unpatched edge devices and forgotten servers are a leading cause of claims, and the same scans show you which vendors put you at risk.
What to look for
It should continuously discover internet-facing assets you didn't know about.
It should prioritize findings by exploitability, not just by CVSS score.
It should monitor your critical suppliers as well as your own assets.
