How to Read a VPN Audit Report: 2026 Transparency Guide

"Independently audited" badges are everywhere — but audits test different things: app code, no-logs policy, or server config. Choosing without understanding scope is misleading.

Audit Types

App pentest ≠ no-logs audit — both valuable, different questions.

What to Read in the Report

1. Scope — product, date, server locations
2. Methodology — black-box, white-box, log access attempted?
3. Findings — critical / high / medium ratings
4. Vendor response — fixes and timeline
5. Limitations — "does not guarantee future compliance" is normal

Old reports (3+ years) may not reflect current stack — check date. Our methodology notes audit dates.

Red Flags

• "Audited" but no public report link
• Marketing PDF only, no technical detail
• Scope limited by vendor request only
• No-logs claim but only app pentest performed
• Major infra change after audit with no follow-up

Known Firms

Cure53 (apps), Deloitte/PwC (no-logs), Securitum (EU assessments) — firm name alone is not enough; read scope.

Providers Without Audits

Open source + transparency (e.g. Mullvad) can build trust differently. Privacy VPN weighs audits and open source together.

No audit ≠ automatically bad — match your risk profile.

Combine With Selection

Audit + jurisdiction + kill switch testing + trustworthy VPN checklist.

ExpressVPN vs ProtonVPN shows audit and jurisdiction differences.

Summary

Treat audit badges as evidence — ask what was tested. Summaries on our reviews; verify full reports on provider sites.
