AdGuard VPN for Windows

Quick summary

AdGuard VPN is a free privacy and security app from AdGuard Software Limited that markets itself with the slogan “Browse like a ninja.” It provides the usual VPN functions — hiding your identity online and letting you appear to browse from different countries — while emphasizing stealth and minimal performance loss.

What makes it different

AdGuard created its own stealth protocol to address two common VPN pain points: compatibility with other VPN apps and speed reductions caused by traffic obfuscation. Their custom protocol masks VPN traffic to resemble ordinary web traffic without introducing the heavy slowdowns that many obfuscation layers cause.

Key capabilities

• Built-in support for torrenting and access to major streaming platforms such as Netflix
• AES-256 encryption combined with modern transport (HTTPS/2) for secure connections
• Automatic kill switch to block data leakage if the VPN drops
• Servers located in 52+ global locations to give users geographic flexibility
• A strict no-logs stance to protect user privacy
• Designed to interoperate with other VPN apps and maintain high throughput thanks to the proprietary protocol

How it performs

Because the protocol is optimized for speed and compatibility, most users will notice only minor reductions in network throughput — if any. The app’s tendency to keep speeds close to baseline makes it suitable for both casual browsing and more demanding tasks like streaming and P2P transfers.

Limitations to consider

• Some premium capabilities aren’t available through a universal free trial — not every feature is unlocked for free users
• No live chat support is provided, which can slow down real-time troubleshooting
• Cryptocurrency payment options are not currently supported

Who should consider it

If you want a straightforward, privacy-conscious VPN that focuses on stealth without sacrificing speed, AdGuard VPN is worth evaluating. Its custom protocol, solid encryption, and no-logging policy make it a strong choice for users who value both performance and privacy.
