GSI tax in IAM budgets: what changes when AI handles integration work?

TL;DR: Identity governance implementations still absorb 30 to 60 percent of year-one spend in services, while fewer than 7 percent of enterprise applications support SCIM and more than half of IGA deployments are distressed, according to Opnova and Gartner. AI changes the economics underneath the iceberg, but the governance model still needs to separate strategic architecture from connector toil.

By the numbers:

• Vendor research puts implementation services at 30 to 60 percent of Year 1 total spend, on top of a median annual contract of around $113,000.

Questions worth separating out

Q: How should identity teams reduce the hidden cost of IGA implementations?

A: Identity teams should split the cost of governance into deployment, connector maintenance, and steady-state operations.

Q: Why do disconnected applications create identity governance risk?

A: They create risk because the organisation cannot reliably see, certify, or revoke access through the same control plane used for integrated systems.

Q: What signals show an IGA programme is becoming unsustainable?

A: The clearest signals are a growing onboarding queue, rising maintenance spend, and a backlog of applications that never reaches full integration.

Practitioner guidance

• Re-baseline IAM spend against recurring integration load Separate licence cost, initial deployment services, and ongoing connector maintenance in every renewal review.
• Map the unmanaged application long tail Count how many in-scope applications lack a native supported connector or stable API path.
• Measure onboarding queue age and throughput Track how many applications are waiting for integration, how long the oldest item has been waiting, and how much new work lands each quarter.
