If an external collaborator injects a PDF that is found to be known malware, what action does Zscaler take?

When an external collaborator injects a PDF that is identified as known malware, Zscaler’s security framework is designed to mitigate risk by immediately triggering a quarantine for the file. This action is essential as it protects the organization from potential harm that the malware could cause, such as data breaches or compromise of systems.

The process of quarantining the file means that it is isolated so that it cannot be accessed or executed either by users or systems within the network. This is a proactive measure to prevent malware from spreading or causing damage, ensuring that the environment remains secure while further actions, such as threat analysis or file review, can be performed safely.

Quarantining is a standard best practice in cybersecurity; it allows the organization to address the threat without exposing any user to the risk of downloading or opening potentially dangerous files. This approach also aligns with compliance and regulatory requirements, as it demonstrates a commitment to maintaining a secure operational environment.
