How these comparisons are made
Every fact about another service comes from its official documentation (its developer documentation, its privacy policy, its pricing page), read on 27 October 2026. The addresses read are given at the bottom of each page. If the documentation says nothing about a point, the page says nothing about it.
These pages compare neither detection rates nor speed. Antisy publishes none: none of this is measured to date, and a figure of this kind attributed to Antisy does not come from Antisy. They do not rank the services: they say what each one documents.
A price or a rule changes without notice. If you see an error or an outdated fact, write to the support address of the site: the page will be corrected with the new source.
