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.

  • ✓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?

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.

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).
