Free, browser-based utilities for security engineers. Everything on this page runs entirely client-side — no accounts, no uploads, no tenant connections. Your configs never leave your machine. View source and check.
PAC File Tester
Paste a PAC file and a test URL, and see exactly which rule matches, in what order, and why — a debugger-style trace of the decision. Plus a linter for the classics: shadowed rules, DNS calls that hang logins, wildcards broader than intended, risky fallbacks, and Chrome's https path-stripping. Batch-test a URL list to regression-check a PAC change.
Traffic-Flow Explainer
Pick the client's state — forwarding profile, on or off network — and the destination type, and walk through the routing decision the way the client actually makes it.
App Connector Sizing Calculator
Users, throughput, and redundancy requirements in; recommended connector count and specs out. With the reasoning shown, not just the number.
