Contact ProtocolProof
Corrections, questions and source suggestions are welcome — especially if a protocol or provider has changed something we should re-check.
The fastest way to reach us is by email. We read everything, and we especially want to hear about factual corrections — a cipher default that has changed, a new audit, a provider that has swapped protocols. Accuracy is the whole point of this site, so a good correction is a gift.
Write to [email protected]. If you are pointing out an error, a link to the source you are citing helps us verify and update quickly.
What we can't help with
We can't provide account support for any VPN provider — for billing, connection problems or refunds, contact the provider directly. We also don't offer one-to-one setup help beyond what our guides cover, and we don't accept paid placements or "sponsored" rankings.
If your question is "which protocol should I use?", the answer probably already lives in our guide to VPN protocols compared.
