BitSight quantifies vendor cyber posture from external telemetry — respected, benchmarkable, outside-in. Polestead answers a question no telemetry can: how much of you does each vendor hold?
You need externally benchmarked cyber ratings for insurers, boards, or M&A diligence — comparisons across companies are the product.
You need to manage third-party risk operationally — classify, assess, and respond — grounded in your exposure, on infrastructure you control. Ratings can still plug in as evidence.
BitSight quantifies external cyber posture; Polestead answers how much of you each vendor holds, classifying the whole register by exposure.
No. It is an operational classification and assessment platform; ratings can plug in as evidence, not as the verdict.
Yes — on-premises, air-gapped, single-tenant EU cloud, or managed SaaS.
