SSL/TLS Encryption

Secure Sockets Layer and Transport Layer Security are both Internet protocols for ensuring security in Internet communications. SSL/TLS encryption is built to secure online data transmitted by encrypting the connection between a browser and a web server.
This means that if you use a browser to log into any private account while connected to a VPN, sensitive info such as your login credentials and personal data will not be snooped or stolen by third parties.

Double VPN

This feature means the VPN will route your online traffic through two servers instead of one, providing an extra layer of encryption for greater security.

Double VPN is ideal for users who require high-level data security to against surveillance and cyberattacks, such as journalists, activists, or anyone handling sensitive data.

Kill Switch

When the Kill Switch feature is turned on, your IP address will be frequently monitored by the VPN. If the VPN connection drops unexpectedly, your IP address changes immediately. Then Kill Switch, which monitors the situation, will automatically cut off your internet to prevent your real IP address and any data from being exposed, ensuring continuous security and anonymity while you are online.

Learn more about Kill Switch and its importance in our VPN Security Explained: Kill Switch, Split Tunneling, More page.

Leaks Protection

While using a VPN, sometimes your original IP address may get revealed, exposing your real geo-location, surfing footprints, and all online activities, due to IP leak, DNS leak, or WebRTC leak.

You can hit the button to download X-VPN to experience its built-in leak protection and start a VPN test to check whether the protective measure is in force.

Onion Over VPN

This VPN feature is one of the best assistants in preventing third-party monitoring and tracking. With Onion Over VPN, the online data will first be routed through a VPN server and then pass through the Tor network, thus gaining multiple layers of encryption and extremely strong security.


Multi-Factor Authentication

MFA in a VPN brings robust security by requiring multiple forms of verification before granting account or resource access. This typically involves a basic username - password and something else you have (like a code sent to your phone), ensuring only authorized users can connect to the VPN and reducing the cyber risk.

Automatic Wi-Fi Protection

The Auto Wi-Fi Protection feature will automatically connect to a VPN server when you connect your device to an unknown Wi-Fi network and encrypt data immediately. For users who often work or study in public places, this feature proactively creates a strong security shield for personal data in public network environments to effectively combat any criminal attempt by unscrupulous individuals.

P2P Support and Protection

P2P ( peer-to-peer) sharing, also torrenting, requires users to download a file via the BitTorrent network, which may lead to cyber risks by exposing your IP address. The P2P Support and Protection in a VPN for torrenting will ensure that your IP address is hidden, encrypt data to prevent monitoring and protect against ISP throttling.

Privacy Features

Privacy features in a VPN use a variety of tricks to get you to wear the Harry Potter Invisibility cloak, hiding from the tracking and prying eyes of any hacker or third-party organization.

10. Hide IP Address

11. No-log Privacy

12. RAM-Only Servers

13. Private Browser

14. Private DNS

Hide IP Address

VPNs can hide IP addresses by routing internet traffic through a server worldwide, which will give you a mask and a cape to pretend you’re surfing from the server’s location.

This is the core function of VPNs, in addition to protecting your identity and preventing tracking, it also can help people bypass the geo-restrictions to access all streaming and other content no matter where you actually are.

For more details on how VPNs protect your identity, see our How VPNs Protect Your Privacy and Online Identity page.

No-log Privacy

The No-Log Policy is a privacy commitment that VPN providers, such as X-VPN and other trusted services, make to their users. They pledge never to log your online activities, VPN usage times, or real IP addresses in any form, nor to store or sell your private data.

Hence, selecting a VPN that strictly adheres to this No-Log Policy and has a clean record free of data leaks is essential for safeguarding your privacy.

Check out our What is a VPN page to understand the importance of a no-log policy.

RAM-Only Servers

Most providers will rely on hard disks to run their services. User data will remain stored on the hard disk until it is overwritten by new data - which obviously leaves a significant risk to user privacy.

Therefore, top services like ExpressVPN use RAM-only servers to add credibility to their No-log policy promises. RAM servers require constant power to retain information, and all data is wiped out in the event of a power failure and reboot, ensuring that no user data can be stored long-term.

Private Browser

A private browser is a feature that only a few leading VPNs will offer. It is essentially a web browser with a higher level of privacy and security, usually built into the VPN client or app. When users surf the web through a private browser, it blocks third-party cookies, disables history, encrypts private data, and minimizes your activity footprint to improve your online privacy.

Private DNS

Generally, we usually use public DNS services provided by ISPs, but these DNS servers make ISPs log everything we do online. Private DNS in a VPN, on the other hand, is a user-specific and secure DNS server.

The VPN handles DNS requests internally and ensures that your browsing activities are kept confidential to the ISP as well as to any third parties, effectively reducing the risk of data leakage and preventing potential data surveillance.


The performance features of a VPN are the aspects that shape its quality of service, reliability, availability, and functionality. They directly determine whether a VPN product is competitive in the marketplace.

Stealth Mode

The stealth mode of a VPN is able to bypass Deep Packet Inspection and other forms of network monitoring by various websites or platforms to help users successfully access restricted content.

The primary purpose of this feature is to disguise VPN traffic so that ISPs or network administrators would think that the user's traffic has nothing wrong as usual to evade VPN detectives.


Obfuscation is a technique employed by Stealth Mode to disguise VPN traffic as regular internet traffic. It plays a big role when users deal with strict internet censorship and regional restrictions. Essentially, Stealth Mode is a user-facing VPN feature, while obfuscation is the underlying tech it uses to achieve its goal.

But different VPN providers may integrate obfuscation in various ways - they might provide obfuscated servers or proprietary protocols with built-in obfuscation.

The Dedicated Servers of X-VPN

Dedicated IP Addresses

A dedicated IP address is assigned exclusively to a single user without sharing with other users, ensuring a consistent online identity and reducing network regulators' suspicions about VPN traffic.

While it doesn't significantly boost VPN performance like dedicated servers do, it enhances VPN security and reliability, making it shine for accessing secure networks such as online banking and official platforms.

Static IP

A static IP is a constant IP address assigned by a VPN provider, giving your device a fixed network identity. It aids in bypassing VPN detections and is crucial for seamless remote work, stable access to security systems, and remote desktops due to its reliability and geographic consistency.

While static IPs and dedicated IPs are very similar in their roles, dedicated IPs are only assigned to one user, while static IPs can be shared. Currently, all these 2 functions are only available to premium VPN users, click the button below to get more info.

Smart DNS

Smart DNS is a tech that unlocks geo-restrictions through DNS Query Redirection for VPN. When you visit a website, your device originally sends a DNS query to change the domain name into its IP address. When you enable Smart DNS, the DNS queries are blocked and rerouted by proxy servers located in different regions.

Because it routes only DNS-related traffic, Smart DNS maintains faster speeds compared to normal VPN services and keeps your original IP address to access the global streaming platforms easily.

Data Compression

Using data compression significantly reduces the amount of data that needs to be routed through the VPN, thus minimizing bandwidth usage. The lesser amount of data will also decrease the time it takes to encrypt and transfer data, improving the VPN speed and performance.

For those who use mobile web surfing, the data compression feature will be good for your wallet.


VPN Shortcut allows users to create a Shortcut on the device's desktop/home screen. Clicking on its icon, users can quickly connect to the VPN service, simplifying and speeding up the connection process.

This feature ensures that your device is secured in the shortest time, reducing browsing risks and facilitating access to global content. For users who rely on a VPN for their work or streaming fans, Shortcut will undoubtedly make their online experience better.
