What is AdGuard VPN?
AdGuard VPN is a VPN service from AdGuard Software Limited.
It encrypts your traffic and hides your IP address behind a remote server.
That keeps your real location private, especially on public Wi-Fi.
The company is based in Cyprus, outside the 5/9/14 Eyes Alliances.
AdGuard offers a full family of privacy tools, like AdGuard DNS.
Its network covers 65+ locations across 53 countries.
The VPN shines brightest when you already use other AdGuard products.
AdGuard VPN
Block ads and hide your IP in one app. Start free with 3 GB of data each month. Paid plans cover up to 10 devices.

| 1 Month | $11.99/month | Short trips or testing paid features |
| 1 Year | $3.99/month | Regular users who want savings |
| 2 Years | $2.40/month | Best long-term value |

Money-back guarantee: The yearly and 2-year plans include a 30-day money back guarantee. The monthly plan does not.

⚠️ Price check: Some review sites list the 2-year plan as $119 billed every two years. Confirm the final total at checkout before you buy AdGuard VPN.
Key Benefits of AdGuard VPN
Here’s what makes AdGuard VPN worth a look:
- Built-in Ad Blocking: AdGuard VPN pairs with the AdGuard ad blocker in integrated mode. Both run at once, so blocking ads happens inside the VPN tunnel.
- Ad-Filtering DNS: You can pick DNS servers that block ads and trackers. A filtering DNS server stops junk before pages load.
- 10 Devices at Once: One AdGuard account covers 10 simultaneous connections. That’s double OysterVPN’s limit.
- Wide App Support: Desktop apps and mobile apps cover Windows, macOS, Android, iOS, Android TV, and Linux. Browser extensions cover Chrome, Firefox, and Edge.
- Privacy-First Base: AdGuard complies with GDPR. Its policy says it never logs IP addresses, browsing history, or timestamps.
- Censorship-Resistant Protocol: The proprietary protocol disguises VPN traffic as regular HTTPS. That helps on networks that block VPNs.
- Free Plan: You can try it risk free with 3 GB a month. No payment is needed to start.

Feature Comparison
Here’s how AdGuard VPN and OysterVPN compare across nine key areas. Pricing gets its own section at the end.
| Feature | AdGuard VPN | OysterVPN |
|---|---|---|
| Starting Price | $2.40/month | $5.99/month |
| Free Plan | ✅ 3 GB/month | ❌ |
| Server Network | 65+ locations, 53 countries | 150+ to 400+ servers (sources vary) |
| Simultaneous Connections | 10 | 5 |
| VPN Protocols | Proprietary | OpenVPN, IKEv2 |
| Kill Switch | ✅ | ✅ |
| Split Tunneling | ✅ | ✅ Windows & Android only |
| Built-in Ad Blocker | ✅ | ✅ |
| Third-Party Audit | ❌ | ❌ |
| Linux App | ✅ | ❌ |
| Lifetime Plan | ❌ | ✅ |
| Best For | Ad-free browsing on many devices | Torrenting and open protocols |
1. Encryption & Security
AdGuard VPN: AdGuard VPN uses AES-256 encryption to secure your data. Its kill switch blocks traffic if the tunnel fails. These security measures cover everyday online security well.
OysterVPN: OysterVPN also uses AES-256 encryption on every connection. It adds advanced security features like DDoS protection and leak blocking. Core protection is similar on both.
⚠️ Warning: Neither VPN has passed a third-party audit. You have to trust each company’s own privacy claims.
2. VPN Protocols
AdGuard VPN: The AdGuard VPN protocol is proprietary. It masks VPN traffic as normal HTTPS, which helps dodge censorship. But it skips OpenVPN and WireGuard, and nobody has audited it.
OysterVPN: OysterVPN lets you choose OpenVPN or IKEv2. Some sources also list WireGuard, while others say it’s missing. Either way, you get vetted VPN protocols.
⚠️ Warning: A closed protocol is harder to verify. If transparency matters most, OysterVPN’s open protocols are the safer pick.
3. Ad & Tracker Blocking
AdGuard VPN: This is where AdGuard puts its focus. Can AdGuard VPN block ads by itself? Yes, through filtering DNS, and even better with the AdGuard ad blocker running alongside.
OysterVPN: OysterVPN includes a built-in ad and malware blocker. It handles pop-ups and known bad domains. It’s useful, but it isn’t a full filtering toolkit.
4. DNS & Leak Protection
AdGuard VPN: You can choose DNS servers that block ads, trackers, and malware. AdGuard DNS comes from the same team. That makes DNS control a real strength here.
OysterVPN: OysterVPN prevents IP, DNS, and WebRTC leaks. Its IP leak protection keeps your real address hidden during reconnects. That’s solid leak protection for a budget VPN.
5. Kill Switch & Split Tunneling
AdGuard VPN: AdGuard VPN includes a kill switch that stops data leaks if the connection drops. Split tunneling lets certain websites or apps skip the VPN. Both work in the main apps.
OysterVPN: OysterVPN’s internet kill switch cuts traffic whenever the VPN connection drops. That prevents accidental data leaks, a crucial feature for torrenting. It also has a split tunneling feature.
⚠️ Warning: OysterVPN’s split tunneling only works in its Windows and Android apps. Mac and iOS users miss out.
Here’s how the split tunneling settings look inside OysterVPN.
6. Privacy & No-Logs Policy
AdGuard VPN: AdGuard VPN follows a strict no logs policy. It collects only minimal data to fix technical issues. AdGuard Temp Mail adds a throwaway inbox for extra online privacy.
OysterVPN: OysterVPN calls its approach a zero logging policy. It says it doesn’t collect or store user data. Its Irish base adds GDPR protection.
💡 Pro Tip: Neither provider has an audited no logs policy. If proof matters, look at audited providers like ProtonVPN.
7. Speed & Performance
AdGuard VPN: AdGuard VPN’s performance suits everyday browsing, not data intensive tasks. Speed tests show about a 20% drop on nearby servers. Paid plans average roughly 58.73 Mbps download speed. Some users still report slow speeds near 10 Mbps from 65 Mbps, plus connection drops.
OysterVPN: OysterVPN’s servers deliver decent speeds on nearby routes. On distant servers, OysterVPN’s speeds drop by about 55% on average. Its smaller server network also limits long-distance options.
OysterVPN also adds DDoS protection, which helps keep online gaming sessions stable.
💡 Pro Tip: Pick the fastest server near you for better connection speeds. Run a quick speed test before video calls, since upload speed dips too.
8. Streaming & Torrenting
AdGuard VPN: AdGuard VPN can unblock Netflix, Disney+, and BBC iPlayer. It struggles with Amazon Prime and Peacock, and some streaming platforms buffer. It doesn’t advertise dedicated P2P servers.
OysterVPN: OysterVPN unblocks popular streaming services like Netflix, Max, ESPN+, and BBC iPlayer. Its dedicated streaming servers help. It struggles with Hulu and Disney+. Torrenting is allowed on all servers with solid P2P safeguards.
⚠️ Warning: Neither VPN suits 4K streaming on distant servers. Expect buffering if you connect to a US server from far away.
9. Apps, Devices & Support
AdGuard VPN: AdGuard VPN’s apps cover Windows, macOS, Android, iOS, Android TV, and Linux. The AdGuard Assistant extension adds one-click page filtering. Its support team works through email and a ticketing system, not 24/7 chat.
OysterVPN: It offers a desktop app for Windows and Mac, an iOS app, and an Android app. There’s no native Linux app or app for smart TVs and consoles. It has no phone or live chat support, and email replies are slow.
10. Pricing & Cost
Here’s how the plans line up side by side.
| Plan | AdGuard VPN | OysterVPN |
|---|---|---|
| Free | 3 GB/month free plan | ❌ |
| Short Term | 1 Month: $11.99/month | 1-Month +2 Months free: $5.99/month |
| Yearly | 1 Year: $3.99/month | 1-Year: $29.99/month |
| Long Term | 2 Years: $2.40/month | Lifetime Access: $59.99/month |
| Money-Back | 30 days (yearly & 2-year) | 30 days (all plans) |
| Payment | Cards, PayPal, crypto | Cards, PayPal |
AdGuard VPN: The 2-year plan is the cheapest way in. The free version caps speeds at 20 Mbps and data at 3 GB. That’s less generous than some free plans, but it costs nothing.
OysterVPN: OysterVPN has no free tier. Its lifetime access option appeals if you plan to keep one VPN for years. Check the checkout page, since listed prices vary between sources.

What Our Review Didn’t Cover
This comparison focused on everyday users and small households. Does AdGuard VPN work in China? Reports say it struggles there, and so does OysterVPN. We didn’t test either inside China. We also skipped router setups and long-term reliability past the October 2026 versions. If you handle sensitive work, pick an independently audited provider.
