1. Mã hóa & Bảo mật
VPN AdGuard: 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.
⚠️ Cảnh báo: Neither VPN has passed a third-party audit. You have to trust each company’s own privacy claims.
2. Giao thức VPN
VPN AdGuard: 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.
⚠️ Cảnh báo: A closed protocol is harder to verify. If transparency matters most, OysterVPN’s open protocols are the safer pick.
3. Ad & Tracker Blocking
VPN AdGuard: 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
VPN AdGuard: 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. Công tắc ngắt & Phân luồng đường hầm
VPN AdGuard: 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.
⚠️ Cảnh báo: OysterVPN’s split tunneling only works in its Windows and Android apps. Máy Mac and iOS users miss out.
Here’s how the split tunneling settings look inside OysterVPN.
6. Chính sách bảo mật và không lưu nhật ký
VPN AdGuard: AdGuard VPN follows a strict no logs policy. It collects only minimal data to fix technical issues. AdGuard Temp Mail adds a throwaway hộp thư đến 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.
💡 Mẹo hay: Neither provider has an audited no logs policy. If proof matters, look at audited providers like ProtonVPN.
7. Tốc độ & Hiệu suất
VPN AdGuard: 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.
💡 Mẹo hay: 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
VPN AdGuard: 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.
⚠️ Cảnh báo: Neither VPN suits 4K streaming on distant servers. Expect buffering if you connect to a US server from far away.
9. Apps, Devices & Support
VPN AdGuard: AdGuard VPN’s apps cover Windows, macOS, Android, iOS, Android TV, and Linux. The AdGuard Trợ lý 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. Định giá & Chi phí
Here’s how the plans line up side by side.
| Kế hoạch | VPN AdGuard | OysterVPN |
|---|---|---|
| Miễn phí | 3 GB/month free plan | ❌ |
| Short Term | 1 Month: $11.99/month | 1-Month +2 Months free: $5.99/month |
| Hàng năm | 1 Year: $3.99/month | 1-Year: $29.99/month |
| Long Term | 2 Years: $2.40/month | Lifetime Access: $59.99/month |
| Hoàn tiền | 30 days (yearly & 2-year) | 30 ngày (tất cả các gói dịch vụ) |
| Payment | Cards, PayPal, crypto | Cards, PayPal |
VPN AdGuard: 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.

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.
