AdGuard VPN Review 2026
By ChrisFounder & Lead AnalystAd-blocking company VPN
AdGuard VPN comes from the well-known ad-blocking company and uses a proprietary protocol designed to blend VPN traffic with normal HTTPS traffic. Based in Cyprus, it benefits from an EU jurisdiction without mandatory data retention.
The VPN integrates seamlessly with AdGuard's ad-blocking products, making it appealing for existing AdGuard users. However, it has no independent security audit, a relatively small server network, and unreliable streaming performance.

Privacy & Security
Security and the AdGuard Protocol
AdGuard VPN does not run OpenVPN or WireGuard. It uses a protocol AdGuard wrote itself, built on QUIC and designed so the traffic looks like ordinary HTTPS rather than like a VPN. That is the most interesting thing about this product, and it is the reason it keeps working on networks that block conventional VPN ports.
The trade-off is that the protocol is closed source and has not been reviewed outside AdGuard. Encryption is AES-256 and the apps carry a kill switch, DNS leak protection and split tunneling, so the surrounding feature set is normal. It is the protocol itself you have to take on trust.
AdGuard does not publish an independent audit of the VPN. For how audit evidence and closed-source components feed the privacy and security scores on this page, see our scoring methodology.
Who Runs It and What They Log
AdGuard VPN comes from the company behind the AdGuard ad blocker, a product with a long track record and a large installed base. That history is a real asset: this is not an anonymous brand that appeared last year, and there is a reputation attached to the privacy claim.
AdGuard states that it does not log the sites you visit or what you do on them. What it does not do is put that claim in front of an outside auditor, which is the standard the higher-ranked providers in our best VPNs for privacy guide meet.
The site publishes its copyright as AdGuard Software Limited but does not state a corporate jurisdiction on its product pages, so treat the Cyprus line in the spec table above as carried in our record rather than as something the site confirms today.
The Free Version
AdGuard runs a genuine free tier rather than a trial. Its site describes 3GB of free traffic per month, with the option to earn more by taking part in AdGuard activities, and limits free accounts to two simultaneous connections against ten on a paid subscription.
3GB is enough to protect a few sessions on public Wi-Fi each month. It is not enough to route a laptop through the VPN full time, and it is nowhere near enough for video. If a free plan is the point, compare it against the options in our best free VPNs guide before settling.
Server Network
AdGuard advertises its coverage by location rather than by raw server count, currently listing more than 75 locations with several cities inside the larger countries. That is a mid-sized network by the standards of this ranking, and a location count arguably says more about where you can appear than a headline server number does.
Server counts move constantly. Check AdGuard's current location list against the countries you actually need before subscribing.
Speed and Performance
QUIC runs over UDP and was designed to cut round trips on lossy connections, so the protocol choice is a reasonable foundation for speed rather than a handicap. What is missing is third-party evidence: because the protocol is unique to AdGuard, the usual cross-provider benchmarks do not cover it.
We do not run our own speed benchmarks. Our speed score reflects published independent benchmarks and provider-reported figures, applied the same way to every provider in our full VPN rankings.
Who AdGuard VPN Is For
AdGuard VPN makes most sense if you already use AdGuard, or if your problem is specifically a network that blocks VPN traffic and you want a protocol that does not announce itself. Ten devices and a real free tier make it easy to try.
It makes least sense if you want an audited provider, a large server network or dependable streaming access. If price is the main driver, our best cheap VPNs guide covers providers at a similar level of spend with broader networks.

AdGuard VPN FAQ
Who owns AdGuard VPN?
AdGuard VPN comes from AdGuard Software Limited, the company behind the AdGuard ad blocker and AdGuard DNS. The VPN is sold as part of that same product family.
What protocol does AdGuard VPN use?
A proprietary protocol built on QUIC, designed so VPN traffic resembles ordinary HTTPS. AdGuard does not offer OpenVPN or WireGuard, and the protocol is closed source and not independently reviewed.
Is AdGuard VPN free?
There is a free tier. AdGuard's site describes 3GB of free traffic per month and two simultaneous connections, against ten connections and no traffic limit on a paid subscription.
How many devices does AdGuard VPN cover?
A paid subscription covers up to 10 devices at the same time. The free version is limited to two.
Does AdGuard VPN have a money-back guarantee?
AdGuard advertises a 30-day money-back guarantee on subscriptions of one year or longer, granted regardless of reason. Monthly subscriptions are described as non-refundable, so the guarantee is not a blanket one.
Has AdGuard VPN been independently audited?
No independent audit of the VPN is published. Given that the protocol is also closed source, that gap matters more here than it would for a provider running standard, publicly reviewed protocols.
Is AdGuard VPN good for streaming?
Streaming is its weakest area and the reason its overall score sits below its privacy score. There are no dedicated streaming servers. See our best VPN for streaming guide if catalog access is the priority.
