A staged rollout is a deployment strategy in cybersecurity and software development where new features, updates, or security patches are gradually introduced to a subset of users or systems before being made available to everyone. This approach helps organizations monitor for potential issues, minimize widespread disruptions, and quickly address vulnerabilities or bugs that may arise. By controlling the pace and scope of deployment, staged rollouts enhance security, improve user experience, and allow for efficient troubleshooting. This method is commonly used for critical updates, ensuring that any negative impacts are contained and resolved before full-scale implementation.
