Identity teams should split the cost of governance into deployment, connector maintenance, and steady-state operations. The biggest savings usually come from reducing bespoke integrations and manual review paths, not from shaving licence costs. If a large share of spend is maintaining what already exists, the programme needs operating-model redesign, not just another renewal negotiation.
Why This Matters for Security Teams
IGA programmes often look expensive because the visible line item is licence spend, but the hidden cost usually sits in connector upkeep, exception handling, and manual certification paths. That is why identity teams need to separate build cost from run cost and treat governance as an operating model, not a one-time rollout. NIST Cybersecurity Framework 2.0 reinforces this by making identity and access governance part of ongoing risk management, not a periodic project.
This matters even more for NHIs, where spend and risk scale together. NHI Mgmt Group notes that NHIs outnumber human identities by 25x to 50x in modern enterprises in the Ultimate Guide to NHIs, which means a model that is already costly for people becomes far more brittle for service accounts, API keys, and automation identities. In practice, many identity teams discover the real cost only after a failed connector, a backlog of access reviews, or a renewal cycle that exposes how much of the programme is still being hand-operated.
How It Works in Practice
Reducing hidden IGA cost starts with breaking the programme into three budgets: deployment, connector maintenance, and steady-state operations. Deployment covers implementation, data modelling, and initial governance workflows. Connector maintenance includes the recurring effort needed to keep HR, SaaS, cloud, PAM, and ticketing integrations working as systems change. Steady-state operations includes access reviews, policy exceptions, remediation, and evidence production.
Once the cost structure is visible, identity teams can target the highest-friction work first. Current guidance suggests prioritising systems that generate the most manual touchpoints, not the ones with the lowest licence cost. That usually means reducing bespoke integrations, eliminating duplicate approval chains, and standardising entitlement models so certifications can be automated. For human users, that often means using policy rules that are easier to map. For NHIs, it means pairing governance with inventory and ownership discipline, as described in the Top 10 NHI Issues and the NIST Cybersecurity Framework 2.0.
- Measure time spent on connector failures, not just implementation hours.
- Track manual approvals, recertifications, and exception queues as operating expenses.
- Retire custom workflows where standard policy logic can handle the same outcome.
- Use authoritative sources for identity data so reviews are not rebuilt by each application owner.
- Assign named owners for each connector and entitlement family so maintenance is not implicit.
The best programmes also review whether IGA is doing work that should belong to adjacent controls such as PAM, secrets management, or cloud-native identity tooling. That is where savings are usually found: removing duplicated governance steps, not reducing assurance. These controls tend to break down when every application has a unique entitlement model and each exception requires a human approval chain because the operating model becomes unscalable.
Common Variations and Edge Cases
Tighter governance often increases process overhead, so identity leaders have to balance assurance against operational drag. In mature environments, the cheapest improvement may be to simplify scope rather than automate everything at once. Best practice is evolving here, and there is no universal standard for how much IGA should be centralised versus delegated to platform teams.
Two edge cases matter most. First, heavily customised enterprise apps can make connector costs dominate the programme, so a rational strategy may be to reduce in-scope systems or redesign the entitlement source of truth. Second, environments with large NHI populations should not force human-style review patterns onto machine identities. NHIs create a different cost curve because their lifecycle is faster, their privileges are broader, and their drift is harder to detect. NHI Mgmt Group research shows that 97% of NHIs carry excessive privileges in the Ultimate Guide to NHIs, which is one reason manual governance becomes expensive so quickly. In practice, the strongest cost reductions come when identity teams redesign the workflow around fewer exceptions and clearer ownership, rather than trying to certify their way out of architectural sprawl.
