Test and Build PAC Files Safely

PAC Lens and the PAC Configuration Studio are built directly into CentaurNexus. PAC Lens retrieves the PAC files currently used in the connected Zscaler tenant, including their content. Instead of downloading and uploading files, you select the required PAC directly in the platform.

For individual analyses and drafts, both tools are also available free of charge and without registration on our website. Manually pasted or selected PAC files are processed entirely in the browser.

After selection, PAC Lens automatically checks the syntax and entry point. Errors, warnings, and guidance appear next to the PAC content that is actually in use.

For a specific case, enter the destination address and, if needed, the client IP. Optional DNS resolution also makes network-dependent conditions traceable.

The result shows DIRECT or PROXY, the complete evaluation path, and the return line that applies. You can see which condition actually makes the decision and which branches do not match.

When a new version is needed, the integrated PAC Configuration Studio takes over. It displays the connected hosted PAC files and loads the saved working draft directly into the guided builder.

Rules can be added, disabled, and checked in a structured way. Generated PAC code and lint guidance update immediately, without administrators having to program every condition by hand.

Before export or deployment, the new version is tested with the same engine. Changes to hosted PAC files remain a deliberate, controlled step and pass through the defined approval process.

Administration reviews the PAC files used in the tenant without a media break. Security sees which condition controls an access request. Analysis and design form a traceable path to a controlled, approved change.
