Should you build or buy Identity Governance & Administration (IGA)?
Identity Governance & Administration (IGA) software automates the lifecycle of user access across enterprise systems, handling joiner-mover-leaver workflows, access certification campaigns, separation-of-duties enforcement, and provisioning to cloud and on-premises applications. It gives security and compliance teams a governed, auditable record of who has access to what and why.
The build-vs-buy decision for Identity Governance & Administration turns on how much of your value comes from the governance logic itself versus the deep provisioning connectors and certification engine that vendors have spent years building; the stable market trajectory has not dramatically shifted this calculus.
Build it, buy it, or bridge?
When building makes sense
The build case for IGA is narrow. The governance logic itself, joiner-mover-leaver rules, access policy definitions, SoD rulesets, is relatively straightforward to model. What's hard to build is the integration plumbing: SCIM provisioning connectors to dozens of SaaS apps, HR system synchronization, and a certification workflow that auditors recognize as compliant. No independent team has shipped a production IGA equivalent from scratch because the value lives in that connector library, not in the policy engine. Where building has the most traction is for organizations deep in the Microsoft stack, where Entra ID Governance bundles governance capability into existing M365 licensing. If Entra covers your provisioning surface and your IT team can configure it, the case for a standalone IGA contract weakens considerably.
When buying makes sense
Buying earns its keep when the organization needs proven provisioning connectors across dozens of SaaS apps, a certification workflow that runs quarterly without manual intervention, and a vendor relationship for the HR system integrations that underpin joiner-mover-leaver automation. Platforms like SailPoint and Saviynt have spent years building that connector library. The compliance argument is also real: access certifications from an established IGA platform carry audit credibility that a custom-built workflow often doesn't. For orgs outside the Microsoft ecosystem, or with complex hybrid environments mixing on-prem AD and cloud directories, a full IGA platform with established connectors is typically the faster, lower-risk path.
The desk read
IGA is compliance plumbing that every organization runs in roughly the same way: joiner-mover-leaver automation, access certifications, separation-of-duties enforcement. The governance logic itself is standardized. Vendors like SailPoint, Saviynt, and Omada have spent years building the SCIM provisioning layer, HR system connectors, and certification engine that underpin production deployments. That integration surface is substantial.
Buying earns its keep when the organization needs proven provisioning connectors across dozens of SaaS apps and a certification workflow that auditors recognize. The build case struggles here because the value isn't in the policy logic, it's in the integration plumbing. Microsoft Entra ID Governance is bundling governance into existing M365 licensing, which is compressing standalone IGA pricing, but it's also raising the bar for what any custom approach would need to match. Orgs already deep in the Microsoft stack should factor that overlap in before signing a standalone IGA contract.
Frequently asked
What is Identity Governance & Administration (IGA)?
Identity Governance & Administration software automates the lifecycle of user access across enterprise systems, handling joiner-mover-leaver workflows, access certification campaigns, separation-of-duties enforcement, and provisioning to cloud and on-premises applications. It gives security and compliance teams a governed, auditable record of who has access to what and why.
When does building Identity Governance & Administration (IGA) make sense?
Building is most defensible for organizations deep in the Microsoft stack where Entra ID Governance covers the provisioning surface within existing M365 licensing. The governance logic is buildable; the SaaS connector library is not.
When does buying Identity Governance & Administration (IGA) make sense?
Buying earns its keep when the organization needs proven provisioning connectors across dozens of SaaS apps, auditor-recognized certification workflows, and HR system integrations without building the plumbing from scratch. Vendors have spent years on that connector library.
What are the main Identity Governance & Administration (IGA) vendors?
Representative vendors include SailPoint Identity Security Cloud, Saviynt Enterprise Identity Cloud, Okta Identity Governance, Omada Identity Cloud. B4 Pro scores the full set.
