Comparison

DecisionOS vs BitSight

BitSight is one of the established outside-in cyber risk rating platforms, alongside SecurityScorecard, Black Kite and UpGuard. The rating is a useful first-pass filter and continuous monitoring tool. DecisionOS produces the audit-defensible memo for a vendor decision, integrating the BitSight rating with all the other criteria a regulated buyer must consider: EU residency, DORA Art. 30 clauses, ISO 27001 fit, TCO, exit strategy, stakeholder alignment, residual risks.

TL;DR

BitSight rates. DecisionOS decides. Use both: rating as an input criterion in the memo, then continuous monitoring.

How DecisionOS is different

BitSight gives one rating per supplier. DecisionOS structures the decision around that rating, plus 10-20 other criteria and stakeholder positions. The memo is the audit artefact; the rating is one of its data points.

Questions we get about this

Does BitSight alone meet DORA Art. 28 requirements?

BitSight contributes to the continuous monitoring requirement, but Art. 28 also expects a documented eligibility assessment and a contractual framework (Art. 30 clauses). DecisionOS produces the eligibility assessment memo; BitSight feeds the ongoing monitoring.

Can the BitSight rating be an input criterion in DecisionOS?

Yes. The decision memo can include external cyber risk rating as a weighted criterion, with the BitSight source link captured as evidence. Native API integration is on the roadmap.

Where is DecisionOS hosted?

Entirely in the EU (Hetzner, Nuremberg, Germany). No application data leaves the European Union. Analytics is self-hosted and cookie-free. A data processing agreement per Art. 28 GDPR is in place with the hosting provider.
