An obfuscated server, sometimes called a stealth server, is a VPN server that disguises your VPN traffic so it looks like ordinary, everyday internet activity. This hides the fact that you're using a VPN at all, which helps you connect on networks and in places that try to detect and block VPN use.
Why VPN traffic gets blocked
Some networks — restrictive workplaces, schools, public hotspots, and certain countries — actively look for the signature of VPN traffic and block it. Standard VPN connections can be recognisable, so even though your data is encrypted, the network can tell a VPN is in use and cut it off.
How obfuscation works
Obfuscated servers scramble or mask the tell-tale signs of VPN traffic, repackaging it so it resembles normal encrypted web traffic. To the network, it looks like you're simply browsing a regular HTTPS website. Your data stays encrypted and private, but the VPN itself becomes invisible to detection systems.
When you'd want a stealth server
- On networks that block VPNs, such as some workplaces, campuses, or public Wi-Fi.
- While travelling in regions with heavy VPN restrictions, where a standard connection might be blocked.
- When you want maximum discretion, keeping the fact that you use a VPN private.
Always check local laws before relying on a VPN somewhere it may be restricted — see is it legal to use a VPN?

Frequently asked questions
Q. Does an obfuscated server slow down my connection? There can be a small amount of extra overhead from disguising the traffic, but for most uses the impact is minor. Use a standard server when obfuscation isn't needed.
Q. Do I always need obfuscated servers? No. They're for networks or regions that detect and block VPNs. On open networks, a standard server is fine.
Q. Is using a stealth server legal? Using a VPN is legal in most countries. Where VPNs are restricted, obfuscation doesn't change the law, so always check local rules first.
