How Does Stealth VPN Make VPN Invisible

A virtual private network or VPN was once something used only by advanced computer users. That has changed, and now even casual users subscribe to VPN services in order to protect their identities, gain access to geo-restricted content and much more. It’s been common knowledge for a while now that groups like the NSA can foil these basic privacy measures, and so stealth VPN has arisen as a solution.

What Is Stealth VPN?

The term stealth in this case is probably inspired by the stealth bombers that the U.S. military uses to circumvent radar. Perhaps the term camouflage paints a clearer picture but isn’t nearly as slick. VPN and stealth VPN are fundamentally the same. These are tunneling protocols through which you can send and receive data via a server and thus obscure your activity. The problem with standard VPN traffic is that it can be detected, and while an ISP or a government may not know what data is being passed back and forth, that may be all the information they need to throttle you or even charge you of a crime. Stealth VPN disguises that traffic so that it doesn’t look any different than non-VPN traffic.

How Does Stealth VPN Disguise Traffic?

So, stealth VPN disguises VPN packs as regular HTTPS packets. HTTPS is the encrypted form of HTTP and used whenever sensitive information is shared, such as between a bank and its customer. HTTPS packets are essential to the Internet as it is and so firewalls won’t block them and detecting them is useless.

How Is VPN Data Transformed?

There is more than just one stealth VPN protocol, which vary in technique. A common approach is to encrypt the data and then alter the data of that packet. VPN headers are replaced with what looks like an HTTPS header. The next step is to encrypt the packet again using encryption algorithms common to HTTPS. Finally, the HTTPS port is used rather than standard VPN ports.

When Should Stealth VPN Be Used?

Stealth VPN should be used in countries were VPN usage is illegal. It should be used where VPN usage may not be allowed, such as at college. It can be used to avoid ISP throttling, and you may just want to use it for the enhanced privacy that it provides.

While there’s certainly a cost to the stealth approach, that cost is becoming less and less as the protocols mature. There will certainly come a time when the stealth adjective will be dropped simply because all VPNs operate that way. It’s rarely a bad choice to choose stealth VPN, and any effect on your Internet speeds has much more to do with the provider than the protocol.
