Comparison

DecisionOS vs G2

G2 tells you what other buyers thought of a product. DecisionOS tells you why your organisation chose one. The two are complementary inputs into a decision. G2 is an evidence source; DecisionOS is the structure that weights that evidence against your specific criteria, dealbreakers and compliance scope.

TL;DR

G2 tells you what others think. DecisionOS captures what you decide.

How DecisionOS is different

G2 is a read. DecisionOS is a write. Most mature buying teams use both: G2 for peer signal, DecisionOS for the structured record of how that signal was weighted against everything else.

Questions we get about this

Can G2 reviews be cited as evidence in DecisionOS?

Yes. G2 review links can be attached to evidence fields, with the Research Honesty layer explicitly classifying them as user-generated peer evidence.

Reicht G2 als Beweismittel im NIS2-Audit?

Nein. Peer-Reviews sind ein gültiger Input, aber kein vollständiger Audit-Trail. NIS2 Art. 20 verlangt nachweisbare Aufsicht durch das Management mit dokumentierten Kriterien, Stakeholder-Sign-off und Risikobehandlung. G2-Sterne erfüllen keine dieser Anforderungen. DecisionOS erfasst G2-Zitate als Evidenz innerhalb eines vollständigen Memo-Schemas.

Where is DecisionOS hosted?

The application, its databases, the self-hosted analytics and all backups run on dedicated servers in Germany operated by a European provider, under an Art. 28 GDPR data processing agreement. There is no hyperscaler, no US fallback and no cross-border replication of stored data. Two steps do leave the EU: decision memos and document extraction are generated by an AI provider in the USA and carry case content, and traffic reaches you through a content delivery provider that terminates TLS in front of the origin. Vendor research runs on anonymized prompts and carries no customer identity. These transfers rest on EU standard contractual clauses, and every sub-processor is listed by name, purpose and location at nexalign.io/hosting. Whether a given workload can accept them is a question we would rather you decide with the facts than discover later. The self-hosted analytics is cookie-free.
