Palo Alto Networks now provides support for Advanced cloud-based features (including, but not limited to Precision AI™ optimized features such as Advanced WildFire: Inline Cloud Analysis, Advanced Threat Prevention: Inline Cloud Analysis, Inline Deep Learning Analysis for Advanced URL Filtering; as well as App-ID Cloud Engine, and Enterprise DLP) when using an explicit proxy as part of a customer's network security infrastructure. Previously, access to various components of advanced security subscriptions required direct internet connectivity, preventing users from maximizing the feature set of their advanced cloud services when internet traffic is handled by an explicit proxy server, which could leave them vulnerable to certain security threats. When Explicit Proxy Support for Advanced Services is enabled, the firewall initiates and completes a proxy handshake and authentication procedures to establish connection to the specified proxy server, which subsequently forwards traffic to the Palo Alto Networks Advanced cloud service servers via the proxy.

For more information about enabling explicit proxy support for advanced services, refer to the configuration documentation for enabling the specific advanced subscription service.
