Converged IGA vs disparate tools: where the governance gap is

TL;DR: Disparate IGA models create manual work, visibility gaps, and audit friction because access requests, reviews, provisioning, and SaaS visibility are split across tools, according to Zluri. The governance problem is structural: control quality depends on whether identity data moves as one system or as disconnected fragments.

Questions worth separating out

Q: How should security teams evaluate a converged IGA model against a disparate setup?

A: Compare the models on data continuity, review accuracy, and revocation reliability, not on the number of features in each tool.

Q: Why does fragmented IGA increase audit and recertification risk?

A: Fragmented IGA forces certifiers to rely on partial evidence from multiple systems, which increases the chance of stale approvals and missed entitlements.

Q: What breaks when access reviews are disconnected from SaaS visibility?

A: Reviewers end up certifying access without a reliable view of which applications are active, who owns them, or whether the entitlement is still used.

Practitioner guidance

• Map control ownership across the entire IGA workflow List which system owns provisioning, review, request approval, SaaS visibility, and deprovisioning.
• Test entitlement consistency after every lifecycle change Run sample joiner, mover, and leaver events and compare the resulting access state across connected tools.
• Retire overlapping tools only after evidence checks pass Do not remove legacy applications until you have verified that the converged platform preserves access history, review artefacts, and revocation outcomes.

What's in the full article

Zluri's full article covers the operational detail this post intentionally leaves for the source:

• The article walks through the full migration logic from disparate to converged IGA, including the sequencing of consolidation steps.
• It shows how Zluri positions each workflow area, including provisioning, access reviews, access requests, and SaaS visibility, inside one operating model.
• The piece includes implementation-oriented guidance on assessing current tools and deciding when redundant applications can be retired.
• It explains the efficiency and compliance claims in more detail, which helps teams compare the model against their own operating constraints.
