Why does combining SaaS management with IGA improve the business case for identity governance?

Why This Matters for Security Teams

Security teams rarely get funded on risk reduction alone. IGA helps show who should have access, but SaaS management shows what that access costs in real dollars. When those two views are combined, identity governance stops being an abstract control program and becomes a measurable operating lever tied to license waste, overprovisioned users, and subscription sprawl.

That matters because finance leaders need a defensible business case, not a theoretical one. The governance team can point to a removed entitlement, a reclaimed seat, or a downgraded license and connect each action to a contract line item. At the same time, the risk story remains intact: excessive access and unused accounts are still governance failures, just ones that now have a cost center attached. This is consistent with the broader control logic in NIST Cybersecurity Framework 2.0, which expects organisations to connect governance outcomes to operational and business priorities.

NHI Management Group’s research on Ultimate Guide to NHIs shows how often identity sprawl becomes a hidden operational burden: 97% of NHIs carry excessive privileges and 96% of organisations store secrets outside secrets managers in vulnerable locations. In practice, many security teams discover the financial upside only after license waste and shadow access have already accumulated for months.

How It Works in Practice

The strongest business case comes from pairing governance workflows with usage telemetry and contract data. IGA answers who has access, who approved it, and whether the entitlement still matches the role. SaaS management answers whether the user is active, which tier they are on, what the app costs, and whether the license can be reclaimed or downgraded without disrupting work. Together, these tools let teams separate necessary access from expensive excess.

A practical model usually looks like this:

• IGA identifies dormant users, orphaned accounts, and access that no longer matches job function.
• SaaS management confirms last-use dates, app ownership, plan tier, and renewal timing.
• Automated workflows trigger revocation, reassignment, downgrade, or consolidation based on policy.
• Finance receives an evidence trail showing the dollar value tied to each action.

That evidence trail is what turns governance from “risk avoided” into “money recovered.” It also supports better prioritisation: a low-risk app with high seat waste may be the first remediation target, while a high-risk system with limited financial leakage may need a different treatment. For access control discipline, the baseline expectations in NIST SP 800-53 Rev 5 Security and Privacy Controls reinforce the need for ongoing review and least privilege, while Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs shows why lifecycle discipline matters when accounts and secrets do not cleanly map to a human seat.

In practice, these controls tend to break down when SaaS ownership is fragmented across departments and usage data cannot be reliably matched to contract entitlements.

Common Variations and Edge Cases

Tighter governance often increases operational overhead, so organisations have to balance savings capture against the effort required to maintain accurate data and exception handling. That tradeoff is real: aggressive reclamation can create friction if licensing terms are complex, if teams rely on shared workspaces, or if access is intentionally bursty rather than steady-state.

There is no universal standard for this yet, but current guidance suggests treating the combined program as a portfolio approach. High-confidence savings should be automated first, while edge cases stay under human review. For example, contractors, seasonal workers, and project-based users may look inactive in SaaS telemetry even though their access is still business-critical. Likewise, some enterprise agreements make downgrade logic more valuable than outright removal because the contract already includes pooled capacity.

Another common issue is overcounting savings. A reclaimed license is not a realised saving unless it avoids a renewal, reduces a committed spend, or replaces a higher-cost tier with a lower one. The governance team should therefore distinguish between “capacity recovered” and “cash avoided.” That distinction is what makes the business case defendable.

NHIMG’s broader NHI research also matters here because the same lifecycle failures that create hidden access risk often create hidden cost waste. When organisations cannot see dormant entitlements or expired secrets, they usually cannot see idle SaaS seats either. The strongest programs use one operating model for both: continuous visibility, policy-driven remediation, and an auditable trail from action to outcome.
