FAQ

Common questions

Can it be bypassed with a VPN?

Cerberus blocks all known VPN provider websites, preventing downloads and updates of VPN software. It also blocks proxy and bypass sites at the DNS level. This makes it significantly harder to circumvent than standard content filters.

What if I forget my password?

That's the point. If you used Fire & Forget, you can request a reset code via email — it arrives after 24 hours, giving you time to reconsider impulsive decisions.

Is there a monthly fee?

No. Pay €20 to download and €12/year from year two onwards. No monthly charges, ever.

What does it block?

Adult content, porn, gambling, proxy sites, and all major VPN providers. You can toggle individual categories on or off in the settings panel.

Does it work on Mac or mobile?

Currently Windows only. Mac and Android versions are in development.
