A simple probe for the networks that matter.

NetHound is designed as an independent testing layer. Instead of being the firewall itself, it verifies whether your existing protections appear to block unsafe categories and allow normal browsing.

Probe

Run a safe browser script to test known-good and policy-test destinations.

Verify

See which categories look blocked, which appear reachable, and which results need manual review.

Improve

Use the results to tune DNS, firewall, proxy, and filtering rules for homes and schools.

Test your network in the browser

Idle
This browser test uses safe and provider-supplied test URLs. It does not access real harmful content. Results are directional because browser networking and CORS can make some blocks appear as timeouts or generic failures.

Test configuration

Leave defaults in place or replace any URL with a test endpoint from your filtering provider.

Click Test Your Network to run the browser checks.
