What’s a stealth VPN? How does stealth make a VPN invisible? You need to know the answers to these and other questions to make good decisions about your online security.
What is stealth VPN?
Essentially, stealth VPN is a protocol that makes VPN traffic look like ordinary internet traffic.
You’ve probably heard of stealth bombers that can fly undetected through enemy radar. Stealth VPN does the same thing, helping VPN traffic get through firewalls.
Why do I need stealth VPN?
Stealth VPN can especially help residents of communist and Muslim countries that have laws and national firewalls. For instance, the Great Firewall of China sets the global standard for censorship.
Businesses also need stealth VPN. To start with, hackers can use deep packet inspection tools to analyze the data that’s exchanged between your business and the internet.
Business can also use stealth VPN protocols to escape the scrutiny of their ISP. For example, ISPs can detect your use of a VPN and either throttle your bandwidth or altogether block your VPN.
You might find other reasons for using a stealth VPN:
- Unblock websites at school or work.
- Access georestricted data.
- Extra privacy and security.
How does a stealth VPN work?
Stealth VPN camouflages your VPN connection, so it looks like typical SSL- secured web traffic.
Websites that use HTTPS rather than HTTP encrypt all data between the site and the visitor’s web browser.
Thanks to efforts by Google, HTTPS is practically required. If a website isn’t secured, Google will bury it in search results. Also , red “Not Secure” warnings appear in browser address bars.
In other words, if you want to own a website that people will visit, you need to use HTTPS.
For this reason, most firewalls allow unimpeded HTTPS traffic.
Basically, stealth VPN looks like HTTPS traffic and can pass undetected through many firewalls.
How does VPN data become stealthy?
Ordinary VPN traffic using OpenVPN includes header information that identifies it.
Through a procedure called “obfuscation,” a stealth VPN removes the information from data headers that identifies it as VPN traffic.
Next, the VPN data is “cloaked” in an HTTPS wrapper which adds a second layer of encryption to it. Afterward, the data is transmitted via Port #443 which is the standard port for SSL traffic.
Is there a stealth alternative to OpenVPN?
Right now, most obfuscated VPN traffic depends on OpenVPN for stealth. However, Microsoft offers the SSTP protocol which has SSL encryption built into it.
