Key Takeaways
  • IGA defines who has access to what, certifies that access is appropriate, enforces SoD, and produces audit evidence for SOX, ISO 27001, and SOC 2, but all of that depends on a unified data model that legacy platforms require years of services work to build.
  • Modern IGA must govern NHIs, autonomous agents, and dynamic entitlements that legacy platforms were never designed to handle.
  • Oleria builds the access graph automatically from live connector data rather than requiring manual role mining, reducing time-to-governance from years to weeks.
  • The functional difference between IAM and IGA is that IAM handles authentication and provisioning mechanics while IGA handles governance, risk, and the compliance evidence that auditors actually require.
