What is browser_broker.exe?

browser_broker.exe is a legitimate Microsoft Windows system process that acts as a security broker for web browsers, particularly Microsoft Edge and Internet Explorer. It manages permissions and controls what browser processes can access on your system, acting as a gatekeeper between the browser and your computer's resources.

The Browser Broker process is a critical component of Windows' security architecture for web browsing. It implements sandboxing technology, which isolates browser processes from the rest of your system to prevent malicious websites or compromised browser components from accessing sensitive files or system resources.
