Comparison
DecisionOS vs Archer (RSA Archer GRC)
Archer is a long-standing enterprise GRC platform: risk register, policy lifecycle, compliance mapping, audit management, third-party risk. DecisionOS sits one layer up: it produces the audit-defensible memo for the underlying decision (which EDR to buy, which IAM to choose, which cloud to migrate to). Archer manages the ongoing GRC processes; DecisionOS produces the decision evidence that flows into Archer.
TL;DR
Archer manages enterprise GRC processes. DecisionOS produces the decision memo that feeds those processes. Complementary, not competing.
Side-by-side comparison
| Criterion | DecisionOS | Archer |
|---|---|---|
| Primary problem | One audit-defensible decision per major IT investment | Enterprise-wide risk register, policy lifecycle, audit management |
| Output | Decision memo, Readiness Score, vendor matrix, stakeholder briefs | Risk register entries, policy attestations, audit findings, compliance dashboards |
| Implementation | Self-service, hours to first memo | 12-24 months implementation, large config and integration project |
| Hosting | Data stored in Germany, AI processing in the USA | Multi-region, depending on deployment |
| Typical owner | CISO, CIO, decision committee | GRC team, internal audit, second line of defence |

- ✓When the audit trail needs to capture stakeholder alignment and trade-offs, not just risk-register entries.
- ✓When time-to-memo matters more than enterprise-wide GRC coverage.
Stick with Archer when
- ·For enterprise-wide risk register management across hundreds of risks.
- ·For policy lifecycle, attestations and compliance mapping at scale.
- ·For audit management and finding remediation across business units.
How DecisionOS is different
Archer is the enterprise GRC platform. DecisionOS is the decision artefact factory. The decision memos from DecisionOS plug into Archer as supporting evidence; Archer's risk register feeds into DecisionOS as compliance overlay.
Questions we get about this
Should we replace Archer with DecisionOS?
No. They are different layers. Archer manages GRC processes; DecisionOS produces decision artefacts. Most large enterprises end up using both: Archer for the enterprise GRC backbone, DecisionOS for each major buying decision.
Can DecisionOS produce the evidence Archer needs?
Yes. The decision memo includes stakeholder positions, weighted criteria, dealbreakers, residual risks and references. That is exactly what Archer expects in supporting documentation for risk acceptance and vendor onboarding.
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?
Book a 30-minute demo at nexalign.io/book. During the demo the team walks a real decision end-to-end using a scenario close to yours (EDR, IAM, sovereign cloud, ERP, whichever fits).
