Sources and limitations

How does VPN Advisor present information?

VPN Advisor is not a testing laboratory, certification body or professional newsroom. This page explains the source types that may appear on the site, how information is labelled and what readers should verify themselves.

Page last updated: September 21, 2026

1. What this site does

Provider profiles and guides organize public documents and information found in independent sources. When a page includes a source link or date, it is kept visible. We do not claim that every field is independently verified or that the whole site is reviewed on a fixed schedule.

2. Source types

This is a reading guide, not a testing protocol. A source being listed does not by itself prove that a claim is true.

Primary sources

Official technical documentation, privacy policies, terms, pricing and app-store listings.

Independent verification

Third-party audits such as Cure53, Deloitte, PwC or SEC Consult, court records and credible security research.

Standards and platform documentation

NIST, IETF, Apple, Google, Microsoft and similar protocol, platform and security documentation.

Secondary sources

Used for context only; critical security or feature claims are not based solely on secondary sources.

3. Information fields

Pages commonly discuss privacy, security, device support, pricing and provider documentation. These are information fields, not a quality score or a completed verification checklist for every provider.

4. Freshness and corrections

  • Pricing, plans, features and audit information can change; a displayed date is only a timestamp for the information it accompanies.
  • The review targets below describe our editorial queue; a material provider change should trigger an earlier check.
  • Information that cannot be confirmed should not be treated as certain; readers should verify current official sources.
  • To report an error or outdated claim, send the URL and supporting source through the contact page.

5. Clear limits and revenue model

  • VPN Advisor does not run laboratory or field tests for speed, streaming, kill switches or user experience.
  • Provider statements are not independent proof; audit reports also have a scope and date.
  • Reader tools produce limited signals from the current connection; they are not provider certifications or overall security results.
  • Google AdSense ads and some affiliate links may appear. Advertising or commission should not change the information, but readers should still check sources and current terms.
  • This site provides general information, not security, legal or financial advice.

Our reference principle is simple: show the source, classify the information, disclose uncertainty, and never present something as tested when it was not tested.
