What must be deployed within an organization to utilize Zscaler root CA effectively?

To effectively utilize the Zscaler root CA within an organization, it's essential to deploy the Zscaler root CA and any necessary custom root certificate authorities. The Zscaler root CA enables secure SSL/TLS decryption, allowing the Zscaler service to inspect and filter encrypted traffic for threats, policy compliance, and performance management.

When properly deployed, the Zscaler root CA facilitates the establishment of trust for SSL/TLS connections within an organization, ensuring that users' secure sessions are not disrupted and that the organization can inspect this traffic in accordance with security policies. By integrating this root CA into the organization's certificate trust store on devices, any SSL connections initiated by users will be recognized as secure, permitting the decryption and analysis of that traffic by the Zscaler platform.

Other options, such as custom application settings, local antivirus software, and network firewall configurations, do not specifically address the requirement of establishing trust in encrypted connections through the Zscaler service. Therefore, they are not prerequisites for utilizing Zscaler root CA effectively.
