The recording/capture prevention feature is a core security solution of Kollus VOD designed to prevent unauthorized copying and external leakage of high-value video content. When a user launches a commercial recording program, a browser capture tool, or a built-in operating system recording feature, the system detects it in real time and applies technical countermeasures.
Detected incidents are logged in the database, and depending on the configured policy, strong security controls such as revoking content access rights or blacking out the recorded screen are applied.
Recording/capture prevention policy
Kollus VOD offers a total of 7 policies tailored to your business security level.
