Comparison
DecisionOS vs Microsoft Purview
Microsoft Purview covers M365-native data classification, DLP, insider risk, eDiscovery, communication compliance and information protection. DecisionOS produces the decision memo for the larger buying questions: do we license Purview E5 or pick a third-party DLP/eDiscovery stack, do we add a non-Microsoft governance layer for hybrid stacks, how do we evaluate Purview against Google Vault if a workspace migration is on the table.
TL;DR
Purview is M365-native compliance tooling. DecisionOS structures the strategic decision that authorises Purview vs alternatives.

Purview operates inside M365. DecisionOS structures the decision that put Purview there. The Purview operating reality (label coverage, policy strictness, false-positive rate) feeds back into DecisionOS as data points for the next decision cycle.
Questions we get about this
If we license Purview E5, do we still need DecisionOS?
Yes for non-Purview buying decisions, which is most of them. Purview is one of many tools whose decision memos DecisionOS structures.
Does DecisionOS help us choose between Purview, Symantec DLP and Forcepoint?
Exactly that use case. The memo captures M365 lock-in, hybrid coverage, EU Data Boundary, TCO and stakeholder positions in one comparable artefact.
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: traffic reaches you through a content delivery provider that terminates TLS in front of the origin, and the AI features are provided from the USA. That second one carries case content: decision memos, document extraction and vendor research all work on what you entered, so where you describe your decision in your own words, that text is part of the request. 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.
How do I evaluate DecisionOS for my next decision?
