Remote Browser Isolation was built to protect users from web-based threats by moving risky browsing activity into a separated environment.
Instead of allowing content to run locally, RBI renders pages in the cloud and streams them back to the user.
That can work for isolating known risk. It doesn’t when an attack looks like normal browsing activity.
RBI only activates when something is flagged as risky. In practice, that means most browsing isn’t isolated at all. Policies decide when to trigger isolation based on URL reputation, categorization, or risk scoring. Everything else runs as normal.That creates a gap.
Push takes a different approach. It operates inside every browser session, giving security teams continuous visibility and real-time detection without relying on isolation triggers or introducing latency.
