IAM Resilience
IAM resilience is the ability of an identity platform to keep delivering an acceptable service despite a failure, an unavailable dependency or a degraded mode.

Definition
IAM resilience is broader than high availability. It covers how the system behaves when a component fails, when an external dependency is lost, when a connector or identity source becomes unavailable, how recovery and replay work, which graceful degradation modes exist, how redundancy is designed, which manual fallback procedures are documented and what business continuity requires. It is designed capability by capability: authentication, provisioning, access review and privileged access do not share the same business impact or the same recovery expectations.
Why it matters
An authentication outage can stop an entire organisation from working within minutes.
The Ariovis perspective
Not every IAM component needs the same availability level. An SSO outage can immediately stop thousands of people from working, while a temporary interruption of a recertification job does not carry the same impact. Resilience must be calibrated on real business risk.

Common pitfalls
- A common mistake is applying one availability target to every IAM component, which costs a lot without reducing risk where it is genuinely high.
