A no-logs claim is worth exactly what verifies it
Every VPN advertises no logs. The phrase is unregulated and costs nothing to print. What separates a meaningful claim from a slogan is external verification: an independent audit by a named firm with a published report, or a court case where the provider was compelled to hand over data and had none to give.
Both kinds of evidence exist and are checkable. Where neither does, a no-logs claim is a promise from a company you cannot inspect — which may well be honest, but is not the same thing as verified. That distinction drives the grade here more than speed, server count or price.
