AdGuard VPN

An open protocol wrapped around a closed, still-unaudited service

🟡 Trust Rating: Moderate

AdGuard VPN is a real product from a real company, and it did something most VPNs never do: it open-sourced its custom obfuscation protocol. Respect. But the two things a privacy reader cares about most are still missing. There is no independent audit of the actual VPN service or its no-logs claim, and there is no anonymous signup: every account needs an email, even if you pay in crypto. Add a Russian founding history and closed-source apps, and you get a capable mid-tier VPN that has not earned the trust Mullvad, Proton, or IVPN have. Fine for bundled ad-blocking. Not an anonymity tool.

What is AdGuard VPN?

AdGuard VPN is one of three separate products from the same company. It is not AdGuard Ad Blocker (client-side ad, tracker, and phishing blocking) or AdGuard DNS (a cloud DNS filtering service). The VPN builds an encrypted tunnel between your device and a remote server to hide your IP and encrypt your traffic. It has its own apps and infrastructure, though paid plans bundle AdGuard DNS Personal at no extra cost.

The legal entity is Adguard Software Limited, registered in Cyprus (Limassol) under number HE 332952. Here is the part every review should state plainly: the company began in Moscow in 2009 and, by AdGuard's own history, moved its head office to Cyprus in 2017. Cyprus is an EU member outside the Five, Nine, and Fourteen Eyes alliances and is bound by GDPR. There is no public evidence of Russian state data access, but some security commentators note that part of the engineering team is reportedly still based in Russia. That is a legitimate scrutiny point, not a confirmed incident.

Critical Privacy Concerns

⚠️ What You Are Actually Trusting

  • No independent audit of the VPN service. As of July 2026 there is no published third-party audit of AdGuard VPN's servers, logging, or no-logs claim. In a December 2024 Q&A, AdGuard's own Chief Product Officer said the company talked to an auditor, then postponed it to open-source the protocol first, and would "return to auditing" only afterward.
  • The Google Play badge is not a no-logs audit. The Android app's "Independent Security Review" badge comes from the App Defense Alliance MASA framework (a Leviathan Security Group code-security review). It checks the app for vulnerabilities. It does not verify the no-logs policy or the servers. Do not read it as one.
  • No anonymous signup. Every account requires an email address, even when you pay with Bitcoin, Ethereum, Litecoin, or Tether. That is a hard limit next to Mullvad's numbered accounts or IVPN's no-email option.
  • It logs more than "nothing." The privacy policy says AdGuard keeps no logs on VPN servers and cannot see what sites you visit. It also collects your traffic volume in bytes (kept 90 days to enforce limits), the number of active connections per account, and account data including your email, password hash, and billing country and postal code. That sits in AdGuard's own data center in Frankfurt, Germany.

The Audit Gap Is the Whole Story

For a VPN, "we don't log" is a promise until someone independent checks. Mullvad has been through Cure53 four times plus a 2025 Assured Security Consultants pen test. Proton VPN has five consecutive annual Securitum no-logs audits. IVPN was reviewed by Cure53 in 2019. AdGuard VPN has none of that for the service itself. Being transparent about not having an audit is not the same as having one. Until one ships, treat the no-logs claim as unverified.

Open Protocol, Closed Apps

AdGuard's best transparency asset is genuine. In January 2026 it open-sourced its obfuscation protocol as TrustTunnel (Apache 2.0), including the spec and reference server and client implementations. The protocol is built to blend in with regular HTTPS traffic (TLS over HTTP/2 or HTTP/3), which makes it harder to throttle or block. Most consumer VPNs never expose their protocol like this. The catch: the apps you actually install (Windows, Mac, iOS, Android, the browser extension) are closed-source. AdGuard calls their GitHub repos "open bug trackers," not source repositories. So the protocol is auditable, but the software running on your device is not.

If You Use It Anyway

Reduce the trust you have to extend

  • Use it for ad-blocking convenience, not anonymity. If your goal is dodging a nation-state or a subpoena, this is the wrong tool. Blocking trackers and unblocking a region, it is fine.
  • Use a dedicated alias email at signup. An email is mandatory, so keep it off your main inbox. A 2018 credential-stuffing attack (reused passwords from other breaches, not an AdGuard server compromise) is a reminder to never reuse a password here.
  • Pay with crypto if you want. It does not make you anonymous while the email is attached, but it keeps a card number out of the picture. Try the free 3 GB tier first to see if it fits.

Treat those as standing promotional prices, not limited-time deals. Monthly plans are non-refundable; annual and longer plans carry a 30-day money-back guarantee. Prices below are live figures from the license page on July 5, 2026.

Plan Price What you get
Free $0 3 GB/month, 4+ locations, 2 devices
1 month $11.99/month 70+ locations, unlimited data, 10 devices, bundled AdGuard DNS Personal

AdGuard VPN vs. Alternatives

AdGuard VPN vs. Mullvad

  • AdGuard VPN: Open protocol, closed apps, email-gated signup, no service audit.
  • Mullvad: Anonymous numbered accounts, cash accepted, four Cure53 audits plus a 2025 pen test. The stronger pick if verifiability is the goal. See our Mullvad review.

AdGuard VPN vs. Proton VPN

  • AdGuard VPN: Cyprus, one open protocol, unaudited service.
  • Proton VPN: Switzerland, five consecutive Securitum no-logs audits, a published transparency report. See our Proton VPN review.

AdGuard VPN vs. IVPN

  • AdGuard VPN: No no-email option, no service audit.
  • IVPN: Gibraltar, no-email signup, Cure53-reviewed. See our IVPN review.

When to Use AdGuard VPN

Reasonable Use Cases

✅ You already use AdGuard's ad-blocking ecosystem and want the VPN bundled in with DNS filtering.

✅ You want light privacy plus geo-unblocking across a lot of platforms, including a router and a CLI client.

✅ You want a free tier to test before spending anything.

Not the Right Fit

❌ You need verifiable, audited no-logs. The audit does not exist yet. Use Mullvad, Proton, or IVPN.

❌ You need anonymous signup. Every account is tied to an email here.

The Bottom Line

Consider AdGuard VPN if:
  • You value the bundled AdGuard DNS and ad-blocking convenience
  • You want wide platform support and an open, inspectable protocol
  • Your threat model is trackers and geo-blocks, not surveillance or law enforcement
Avoid AdGuard VPN if:
  • You require an independent audit of the actual no-logs claim
  • You need to sign up without handing over an email
  • The Russian founding history or closed-source apps are dealbreakers for you

⚠️ Final Assessment

AdGuard VPN is a competent mid-tier VPN that did one genuinely rare thing (it open-sourced its protocol) and still has not done the two things that would earn a privacy reader's trust: an independent audit of the service and an anonymous signup path. Those facts sit side by side. Use it for what it is good at, bundled convenience and light privacy, and do not mistake it for an anonymity-grade tool until an audit of the real service is published.
