What action does Zscaler take when it encounters completely unknown content?

When Zscaler encounters completely unknown content, it employs a sandboxing approach to analyze the content while awaiting a verdict. This process allows Zscaler to safely execute and observe the behavior of the unknown content in a controlled environment, isolating potentially harmful elements and assessing their risk level without putting the broader network or infrastructure at risk.

Sandboxing is a critical component of a comprehensive security strategy, especially given the evolving landscape of cyber threats where attackers constantly develop new tactics and payloads that may not be recognized by traditional antivirus or filtering mechanisms. By isolating unknown content, Zscaler can determine whether it poses a threat and make informed decisions about what action to take, enhancing overall security while maintaining operational efficiency.

This method is essential for proactive threat management, allowing organizations to address emerging threats promptly without disrupting user access or experience.
