An obfuscated VPN, or stealth VPN, disguises VPN traffic as regular internet data. While a VPN hides your activity, your VPN use itself can be detected. Obfuscation alters the traffic to appear normal, ensuring complete anonymity from ISPs, firewalls, and websites.
Some VPN IP addresses are marked as suspicious for sending too much traffic or flagged before. Data from these IPs can be easily recognized and blocked.
Many VPN protocols use specific ports like 1194 for OpenVPN and 1701 for L2TP. Monitoring traffic on these specific ports is a straightforward way to identify VPN use.
Deep Packet Inspection (DPI) is a traffic analysis method that inspects both the header and the payload of data packets. It can be used to find identifiable VPN patterns.
Many VPNs employ standard protocols with unique data signatures. These identifiable patterns, such as those from OpenVPN or L2TP, can be flagged by detection systems.
X-VPN’s advanced obfuscation shields your connection from detection through multiple techniques.

X-VPN offers a global pool of over 10,000 VPN servers. This vast IP address prevents blocks that target known VPN IPs. You can always connect to a fresh, clean IP.
To avoid filters that monitor specific VPN ports, X-VPN can route all traffic through common, whitelisted ports such as HTTPS port 443. This makes your VPN connection appear identical to regular, secure web browsing traffic.
Our obfuscation technology actively scrambles VPN packet headers. This disrupts the identifiable patterns that DPI systems search for. It makes your encrypted traffic appear as random, regular data.

With our proprietary Everest Protocol, we obfuscate and disguise the entire VPN connection. By altering its inherent signatures and using TLS encryption, it removes the fingerprints that firewalls use to identify standard protocols like OpenVPN.




Obfuscation is enabled by default in X-VPN's Everest Protocol for free. Everest TLS is recommended for the highest level of disguise.

Connect to a VPN server and enjoy anonymous browsing.
Obfuscation you control, not a preset. Enter any normal website (like google.com), and X-VPN will shape all your encrypted traffic to look like visits to that site. No fixed patterns, no one-size-fits-all, just obfuscation built around your rules.


Whenever you feel too much “cared” by your ISP, network administrator, or other entities, enable VPN obfuscation. It hides the very fact you're using a VPN, going beyond standard privacy.

If a regular VPN connection fails to access some platforms, switch to an obfuscated VPN. It masks your VPN's digital fingerprint, effectively slipping through VPN filters that target regular protocols.

Turn on an obfuscated VPN for travel, especially when using hotel and airport public Wi-Fis. It ensures you can access all your usual sites without being noticed, no matter where you are.
Stop being detected. X-VPN makes your VPN invisible with one tap. Download the best obfuscated VPN free!

An obfuscated VPN provides the ultimate solution for true online privacy. It benefits your browsing in various aspects.

A standard VPN can be noticed and throttled by your ISP. Obfuscation disguises your VPN connection as normal web browsing, so your ISP sees only regular HTTPS traffic and has no reason to slow you down.
Firewalls at work, school, or on public Wi-Fi sometimes limit standard VPN connections. Regain your VPN connection and maintain privacy online on any network.


Avoid CAPTCHAs and throttling caused by VPN detection. X-VPN uses advanced obfuscation to disguise your traffic and a large, clean IP pool to prevent blacklisting. Enjoy smooth streaming and anonymous browsing without interruptions.
While all servers of X-VPN are obfuscated servers, premium users can enjoy customizable obfuscation rules and more.

Yes, using a VPN can be detected. Although all your online activities are encrypted well with VPN protection, your ISP can know the fact that you are using a VPN. VPN obfuscation technology stops that, making your VPN traffic look like normal web traffic and undetectable.
Using an obfuscated VPN is legal and allowed in most countries, except for those that strictly ban VPN use. However, there are potential legal implications if you are trying to use an obfuscated VPN to access content that is illegal in your area. Please check your local regulations before taking further steps.
Obfuscated VPN is not 100% undetectable, it depends largely on the VPN service provider you choose and the inspection technology the other side uses. Getting a trustworthy VPN service like X-VPN is essential if you want to increase your untraceability.
Yes, VPN obfuscation will slow down your internet speed. The extra layers of encryption and encoding added by obfuscation technology require more processing time. An optimized obfuscation protocol like Everest TLS-3 can significantly reduce the drop.
Yes, X-VPN's obfuscated Everest protocols are free to use, except for Everest TLS-3, which has top-tier disguise capabilities. Besides, the customized obfuscation is also paid to use. You are secured with a 30-day money-back guarantee.
