How to choose an IAM, IGA and PAM stack
IAM decisions rarely fail on the core identity provider. They fail at the governance and privileged-access layers, because those two sub-decisions get bundled into the IAM RFP and never get their own weighted scoring. The right decision structure keeps IAM, IGA and PAM as three overlapping but individually-scored decisions, with sovereignty and federation as upstream dealbreakers.
TL;DR
Treat IAM, IGA and PAM as three decisions, not one.
Who owns this decision
CISO or IAM-lead as decision owner, IT Security, IT Operations, HR-IT and a Data Protection Officer as stakeholders.
Key criteria to weight
Federation coverage
SAML, OIDC, SCIM depth across your actual application landscape. Coverage gaps become integration projects.
Lifecycle automation
Joiner-mover-leaver without manual tickets. Directly affects audit findings.
Governance and access review depth
Certifications, SoD analytics, campaign workflow. Weak here means IGA as a separate decision.
Privileged access and session control
Vaulting, session recording, just-in-time elevation. Often a separate PAM decision.
Sovereignty and hosting
EU-hosted tenant, key management, sovereign cloud eligibility. Frequently a dealbreaker.
TCO and connector cost
Per-identity pricing versus flat. Connector fees. Professional services dominate year 1.
Step-by-step decision flow
- 1
Split the decision
Explicitly decide whether IAM, IGA and PAM are one decision or three. Re-bundle only if stakeholders and budgets genuinely overlap.
- 2
Set sovereignty dealbreakers
EU-hosted, key control, federated identity across sovereign boundaries. Not scored, binary.
- 3
Map your applications
The federation matrix decides which vendor actually fits. Walk the top 50 applications and their protocols.
- 4
Weight governance criteria
If you are in NIS2 / DORA scope, governance weights rise substantially.
- 5
Pilot with real lifecycle events
Joiner, mover, leaver, offboarding. Time them. Watch the SoD logic. Do not let vendors demo happy-path only.

- Shortlist
- Ausbau der vorhandenen Microsoft-Plattform um deren Governance-Modul
- Eigenständige Identity-Suite eines Cloud-IAM-Anbieters
- Spezialisierte IGA-Plattform als Aufsatz auf die vorhandene Plattform
- Decision
- Ausbau der vorhandenen Microsoft-Plattform um das Governance-Modul für Workforce Identity. PAM bleibt ein eigener Vertrag mit einem spezialisierten Anbieter.
- Rationale
- Die Bindung an einen Anbieter wurde bewusst in Kauf genommen: der Bestand ist ohnehin Microsoft-zentrisch, und jeder Wechsel hätte die Legacy-Bestandssysteme mit angefasst, was in diesem Haus das teuerste Einzelrisiko gewesen wäre. Der IGA-Aufsatz hätte die geforderte Tiefe gebracht, aber als drittes System neben Plattform und PAM mehr Schnittstellen erzeugt, als das Team betreiben kann. Die eigenständige Suite scheiterte an der Lifecycle-Anbindung: sie an die Bestandssysteme zu hängen wäre ein eigenes Projekt neben dem eigentlichen geworden.
- Residual risks
- PAM-Workflow noch nicht in die Governance-Reviews integriert
- SoD-Analytik für Solvency-II-relevante Rollen muss in Phase 2 ergänzt werden
Compliance note
NIS2 Art. 21 expects identity and access management as a named measure. DORA Art. 9 and 28 add explicit expectations on ICT risk management around identity. Under both, the decision memo is the evidence file.
Common pitfalls
- Bundling IAM, IGA and PAM into a single RFP with one weighted score.
- Under-weighting legacy connector requirements.
- Ignoring IGA until after IAM contract signature, then paying twice.
- Skipping sovereignty dealbreakers for public-sector workloads.
FAQ
What is the difference between IAM, IGA and PAM?
IAM (Identity and Access Management) covers the broad category. IGA (Identity Governance and Administration) is the governance-heavy subset: access reviews, SoD, joiner-mover-leaver. PAM (Privileged Access Management) focuses on elevated accounts and session recording. Most enterprise decisions involve an IAM core plus an IGA and PAM overlay.
Do I need a separate IGA product, or does my IAM platform cover it?
Many IAM platforms (Entra ID, Okta, Ping) bundle baseline governance. Deep IGA needs, certifications, SoD analytics, connectors to legacy systems, often still drive a separate IGA platform. The decision memo should surface this as an explicit dealbreaker if you are under NIS2 or DORA scope.
Is sovereign IAM a hard requirement in the EU?
For most enterprises, no; for sovereign-cloud candidates and public-sector workloads, yes. DecisionOS treats sovereignty as a dealbreaker that is toggled on or off at the start of the decision, not as a scored criterion.
