Grade a vendor's posture before you sign

Enter a vendor's domain. We grade the same public security signals an attacker or an examiner would check first — then give you the questions to ask that a public check can't answer.

Try a vendor you're evaluating. The grade takes about 20 seconds and reads only public DNS and HTTP settings — nothing intrusive.

Why it matters

Your risk is the sum of your vendors' risk

Most reported security incidents trace to a third party. Regulators increasingly expect documented due diligence proportionate to the data and access each vendor has — and "we sent a questionnaire" isn't the same as evidence. This check gives you a fast, objective first read so you know which vendors deserve a deeper look.

Turn a vendor list into a risk-ranked program

We build tiered third-party risk programs: inventory, due diligence proportionate to access, contract clauses, and ongoing monitoring — the version examiners accept as evidence.
