Comparison

DecisionOS vs LeanIX

LeanIX gives you a structured view of your current technology portfolio: applications, services, SaaS, dependencies. DecisionOS gives you a structured way to decide what to add, replace or retire. Many enterprise architecture programmes use LeanIX for the map and DecisionOS for the decisions that reshape the map.

TL;DR

LeanIX tracks your portfolio. DecisionOS decides what changes.

Questions we get about this

Can LeanIX and DecisionOS be used together?

Yes. DecisionOS decisions feed LeanIX portfolio updates with a traceable reason-of-record.

Ist DecisionOS eine EAM-Alternative?

Nein. LeanIX (jetzt SAP) ist Enterprise Architecture Management mit Application-Portfolio, Capability-Mapping und Tech-Radar. DecisionOS ist Entscheidungs-Infrastruktur für die einzelne Investitions- oder Migrations-Entscheidung im Architekturkontext. Viele Architekten verwenden LeanIX für die Bestandsaufnahme und DecisionOS für die strukturierte Entscheidung über Veränderung.

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.

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).
