How I test

For each tool I set it up and use it hands-on where I can — configuring the VPN, running speed and leak tests, reading the provider's audit report — then verify every claim against primary sources. Where I can't test directly, I aggregate and cite real user reports and label them as such. I never promise absolute protection; I report what the evidence shows.
