An exit test is a practical exercise that checks whether a service can be moved away from a provider without major disruption. In cloud and outsourced IT environments, it validates the real-world ability to transfer data, reconnect systems, and keep critical operations running when a contract ends, a provider fails, or a migration becomes necessary.
In cyber security, exit tests matter because dependency itself is a risk. A provider outage, ransomware incident, legal dispute, or concentration problem can turn a normal service relationship into an operational bottleneck. Testing the exit path helps defenders find hidden obstacles such as proprietary formats, missing admin access, weak backups, or undocumented subcontractors. In DORA-style governance, exit tests are evidence that resilience is not just promised on paper but exercised in practice.
