AdGuard VPN Review 2026 - Open Protocol, No Audit Yet
Category: Best Privacy VPN
By Jordan Pierce, Senior Editor · Last updated September 2026
TL;DR: AdGuard VPN is a mid-tier VPN from the makers of the popular ad blocker. It runs on an open-source protocol called TrustTunnel and states a strict no-logs policy, but it has not yet passed an independent no-logs audit. Choose it if you already live in the AdGuard ecosystem and want bundled DNS filtering; pick an audited provider such as Proton VPN if verified privacy is your top priority.
How We Tested
Our editorial team compared AdGuard VPN against publicly documented specs and independent reviews. We cross-checked server counts, protocol details, logging claims, and pricing on the vendor's site and on third-party tests. This review is not sponsored, and no affiliate relationship influences our verdict.
AdGuard VPN at a Glance
| Spec | Detail |
|---|---|
| Provider | AdGuard Software Ltd (Cyprus, EU) |
| Protocol | TrustTunnel (open source, built on TLS + HTTP/2 or HTTP/3) |
| Server footprint | 70+ locations across 61 countries |
| Devices | Up to 10 simultaneous connections |
| No-logs audit | Claimed, not yet independently verified |
| Free tier | 3 GB/month, 2 devices |
| Best for | AdGuard users, light privacy, tracker blocking |
Speed & Performance
TrustTunnel is built on TLS and HTTP/2 or HTTP/3, so its traffic resembles ordinary HTTPS. In independent tests, nearby servers delivered smooth browsing and HD streaming, while long-distance hops showed the expected drop versus WireGuard-native rivals. The 70+ location network is smaller than ExpressVPN or NordVPN, so check the location list before you pay. We did not run our own benchmark; real speeds vary by server and time of day.
Security & Privacy
AdGuard VPN ships a kill switch and "Exclusions" (its take on split tunneling), and paid plans bundle AdGuard DNS Personal for network-level ad and tracker filtering. The jurisdiction is Cyprus, so EU privacy law applies. The company says its servers keep no activity logs and no originating IPs. That claim remains unaudited: AdGuard has said publicly it postponed an independent audit to open-source the protocol first. Open code is real transparency, but a protocol audit and a no-logs audit are different things. If you need proof, see our Surfshark review or our Mozilla VPN review, both of audited services.
Streaming & Unblocking
AdGuard VPN can reach major streaming platforms on popular regions, though unblocking is inconsistent on some Netflix libraries compared with dedicated streaming VPNs. For travelers who want to reach their own paid subscriptions abroad, it is serviceable. It is not a replacement for a purpose-built unblocking tool, and performance depends on the exit location you choose.
Device Compatibility
AdGuard VPN covers effectively everything: Windows, macOS, Linux, iOS, Android, Android TV, Apple TV, routers, a CLI client, and browser extensions for Chrome, Edge, Firefox, and Opera. That breadth is a genuine strength, especially for households with mixed hardware.
Pricing & Value
The free plan gives 3 GB of traffic per month on 2 devices, with no card required, which is enough to genuinely test the protocol. Paid tiers cover 10 devices and bundle AdGuard DNS Personal:
- Monthly: $11.99/month, no money-back guarantee.
- 1-year: $3.99/month ($47.88 billed), 30-day refund.
- 2-year: $2.99/month ($71.76 billed), 30-day refund.
Two things to know: the monthly plan is non-refundable, and the AdGuard ad blocker is a separate license. At $2.99/month on the long plan, the price is competitive for what is included.
Pros & Cons
Pros
- Open-source TrustTunnel protocol (reference code published).
- Bundled AdGuard DNS blocking of ads and trackers.
- Real, usable 3 GB/month free tier.
- Wide platform support, including routers and a CLI.
Cons
- No independent no-logs audit yet.
- Smaller server network than the largest providers.
- Monthly plan has no refund.

Frequently Asked Questions
Has AdGuard VPN been independently audited?
Not for the no-logs claim. Its Android app passed a 2025 security assessment by Leviathan Security Group, and the TrustTunnel protocol was open-sourced in January 2026, but no public server-side no-logs audit exists yet.
Does AdGuard VPN keep logs?
AdGuard says its VPN servers keep no activity logs and no originating IPs. The account layer stores your email, billing data, connection counts, and traffic volume for 90 days. That narrower claim is unverified by an independent auditor.
Which devices does it support?
Windows, macOS, Linux, iOS, Android, Android TV, Apple TV, routers, a CLI client, and Chrome, Edge, Firefox, and Opera extensions.
Is there a free tier?
Yes. The free plan offers 3 GB of traffic per month on 2 devices, with no card required.
Does it work for streaming?
It can reach several major platforms on popular regions, but unblocking is inconsistent on some Netflix libraries. Treat it as good-enough for casual travel use rather than a dedicated unblocking tool.
My Take / The Bottom Line
AdGuard VPN is a competent, honestly priced mid-tier service from a company with a real reputation to protect. The open-source protocol is a genuine differentiator, and the bundled DNS filtering is a nice convenience. The honest caveat is the missing no-logs audit: until that lands, treat AdGuard VPN as solid light-privacy and tracker-blocking tool, not an anonymity-grade service. If you are already an AdGuard user, it is an easy recommendation; if verified no-logs is your first requirement, an audited alternative is the safer pick.
