What Is Stealth VPN & How Does It Work?

With an effort to stay anonymous online, it is useful to know more about What Is Stealth VPN & How Does It Work?

In our today’s useful article guide, we are going discuss the benefits of Stealth VPN, how it works and how you can use it to take your privacy and security to the next level.


A Stealth VPN is a VPN server or protocol that can disguise VPN traffic as regular traffic. It helps conceal your online activities from ISPs (Internet Service Providers) and third parties. A Stealth VPN takes it one step further and ensures that no entity can determine your use of a VPN. It helps you to bypass VPN blocks and firewalls easily.

Even if network administrators employ DPI (Deep Packet Inspection), your VPN will remain private and secure. As you can see, there are many benefits to using a Stealth VPN. In this guide, we’ll explore the ins and outs of Stealth VPN, how it works, and what makes it stand out from other VPN Protocols. So, if you’re ready, let’s get started!

Why Do I Need To Use a Stealth VPN?

A Stealth VPN, also called an obfuscated VPN, adds an extra layer of privacy and security by making your VPN challenging to detect by third parties. There are several reasons why we would need a Stealth VPN:

Bypassing Censorship

Many countries have implemented Censorship on certain websites and content. These countries also block access to specific online services. A Stealth VPN enables users to bypass the Censorship and gain access to such content. Since Stealth VPN disguises VPN traffic as regular traffic, it makes it harder for authorities to detect and block.

Privacy & Security

Stealth VPNs enhance your privacy and security by making it difficult for ISPs, hackers, and other third parties to monitor and track your online activities. It is especially crucial when using a public network with higher security risks.

Avoid Throttling

Some ISPs can throttle or slow down your internet connection when they detect that you’re using a VPN. A Stealth VPN can make it harder for ISPs to see whether you use one. It helps you avoid throttling.

Thwarting Deep Packet Inspection

Some regions and ISPs use DPI (Deep Packet Inspection) technology to inspect and control internet traffic. Stealth VPN can help bypass Deep Packet Inspection by disguising VPN traffic as regular internet traffic, making it difficult for DPI systems to identify and block VPNs.

Preventing VPN Blocks

Some websites, streaming platforms, and online services block VPN traffic to implement regional restrictions. A Stealth VPN helps you gain access to these services and makes it difficult for such platforms to identify or block VPN connections.

How Does Stealth VPN Work?

Here’s how a Stealth VPN typically works:

1) A Stealth VPN encrypts your internet traffic to protect it from getting monitored or tracked by third parties. This encryption is necessary to enhance your privacy and security.

2) The key feature of Stealth VPN is Obfuscation. Obfuscation means disguising the VPN traffic as regular HTTPS traffic. It prevents network filters and DPI systems from identifying or blocking the VPN connection.

3) There are several methods for obfuscation. One is Port Randomization, where Stealth VPN will randomize the ports to distinguish them from regular traffic. The other way is Protocol Obfuscation, where Stealth VPN uses custom or modified protocols so that they can’t be detected. Stealth VPN also tunnels its traffic through HTTPS protocol, which provides secure web browsing. Traffic Padding is another technique that enables adding extra data to VPN packets to make them look like regular data packets.

4) Stealth VPN providers often come with special servers optimized for obfuscation. Once you connect to the server, you can benefit from the obfuscation techniques.

5) Once connected to a Stealth VPN server, your internet traffic is routed through it the same way as with a regular VPN.

How To Choose The Best Stealth VPN

Consider various essential factors before deciding which Stealth VPN is best for you. Let’s go over the most important ones:

  • Use a VPN provider that mentions their obfuscation techniques and that the ones they employ are effective against censorship or blocking in your location.
  • Choose a VPN provider with servers in multiple locations, especially in regions where you need to access content and bypass censorship.
  • A VPN service should have a strict No-Logs Policy, meaning they don’t record or monitor your online activities. Ensure that the VPN provider you opt for has strong encryption and security protocols to enhance the privacy and security of your data.
  • You should also test the VPN’s speed and performance. Obfuscation techniques can sometimes impact speed, so ensure the VPN provider has a reasonable speed that suits your needs.
  • You should also check the VPN’s track record for uptime and reliability. A VPN that frequently experiences downtime won’t be helpful, especially in regions with strict censorship.

Not all VPNs can be considered Stealth VPNs when considering the above factors. Therefore, AstrillVPN is recommended for Stealth VPN Protocol alongside with Nordvpn and Surfshark because they allow you to bypass censorship and VPN blocks, hide your online activities from ISPs and other prying eyes, and enhance your privacy and security. And a bonus is that they help you to set up StealthVPN easily.

A Brief Overview Of Other VPN Protocols – What Makes Stealth VPN Stand Out?

There are different VPN protocols with unique strengths, characteristics, and weaknesses. As you will notice, Stealth VPN differs from other protocols and has specific purposes. Let’s go over the most common VPN protocols:


  • It is open-source and configurable. It has excellent security and is one of the most secure VPN Protocols.
  • However, it can be slower than other VPNs due to the encryption overhead.

L2TP/IPsec (Layer 2 Tunneling Protocol with IPsec):

  • It also offers excellent security and is considered one of the most secure VPN protocols.
  • It is susceptible to blocking and throttling in certain situations.

PPTP (Point-to-Point Tunneling Protocol):

  • It is fast and easy to set up.
  • It is outdated and less secure as compared to recent VPN protocols. It is not recommended for people to be conscious about their privacy and security.

SSTP (Secure Socket Tunneling Protocol):

  • It is highly secure and used specifically for Windows systems.
  • It is only available for use on Windows. It is not widely supported on platforms other than Windows.


  • It has a fast connection speed and is built with modern cryptographic principles and strong encryption.
  • WireGuard is not designed for obfuscation or preventing VPN blocking.

What Makes Stealth VPN Different?

Stealth VPN is not a distinct Protocol but a feature or technique applied to the protocols mentioned above or custom protocols. StealthVPN bypasses blocking, censorship, and deep packet inspection (DPI). It involves obfuscating VPN traffic to make it look like regular internet traffic.

If your main goal is privacy, security, and gaining access to geo-restricted content, then a standard VPN Protocol would be better for you. If you’re in a country with stringent censorship and need to bypass VPN blocking, or if you’re concerned about deep packet inspection (DPI) from identifying and blocking your VPN traffic, then a Stealth VPN is the best choice. StealthVPN adds an extra layer of obfuscation to your VPN traffic, making it difficult for network administrators to block and detect it.


Stealth VPN helps you bypass heavy censorship and takes your privacy and security to the next level, making it difficult for ISPs and other third parties to detect that you’re using a VPN. After considering some critical considerations, you can invest in a Stealth VPN that works best for you.
