Gradual rollout is a deployment strategy where software updates, features, or security patches are released to users in phases rather than all at once. This approach allows organizations to monitor the impact of changes, quickly detect issues, and minimize risks by limiting exposure if problems arise. Gradual rollout is commonly used in cybersecurity to ensure that updates are stable and do not disrupt user experience or system performance. By controlling the pace of distribution, companies can address unforeseen issues before the update reaches the entire user base.
