Polestead vs SecurityScorecard

SecurityScorecard grades vendors from the outside — a letter grade built from what scans can see. Polestead classifies them from the inside — by what each vendor holds of yours. Different questions, different answers.

SecurityScorecard
Polestead
The model
Outside-in security ratings — A–F letter grades from external scan data.
Inside-out classification — vendors tiered by your exposure across six access vectors.
What it sees
A vendor's internet-facing posture — ports, certificates, leaked credentials, domains.
What the vendor holds of yours — data, network paths, facilities, designs, people, supply.
Coverage
Scored portfolios — typically the vendors you nominate and license.
The entire vendor register by default — classification is the platform's baseline behavior.
Deployment
US-headquartered multi-tenant SaaS.
On-premises, air-gapped, single-tenant EU cloud, or managed single-tenant SaaS.
The vendor's view
A public grade the vendor may have to dispute.
Private classification. External signals enter only as evidence — never as a public verdict.
Choose SecurityScorecard if…

You want continuous external monitoring of vendor cyber posture as a standalone signal, and a widely recognized ratings benchmark your board already knows.

Choose Polestead if…

Your risk is defined by what vendors hold of yours — not what they show the internet — and your data can't live in someone else's jurisdiction. You can still bring external ratings in as evidence.

FAQ

Common questions.

How is Polestead different from SecurityScorecard?+

SecurityScorecard grades vendors from external scans; Polestead classifies them by your own exposure across six access vectors, with external signals as optional evidence.

Can I still use security ratings with Polestead?+

Yes. Bring an external scanning license and attach its findings as evidence, scoped by tier.

Where does my data live?+

On-premises, air-gapped, single-tenant EU cloud, or managed SaaS — your choice, unlike US-headquartered multi-tenant ratings platforms.
