Continuity risk is the possibility that a change will interrupt normal operations or make a service unavailable. In cybersecurity, it can arise during software migrations, infrastructure upgrades, or changes to identity and access systems, even when no attack occurs.
For example, moving to a new platform may reveal undocumented dependencies or leave old and new systems operating with inconsistent access controls and monitoring. Teams reduce continuity risk by mapping dependencies, testing changes, planning staged transitions and rollback options, and verifying that critical services remain available throughout the change.
