3. Not every VPN has what it takes to disguise VPN traffic and bypass VPN restrictions.
4. ExpressVPN, NordVPN, and Surfshark are all excellent VPN providers witha proven ability to stay undetected.

How do platforms detect VPN connections?

Schools, workplaces, websites, and even some governments are on the lookout for VPNs and will block any connection they suspect is using a VPN.

Whether it’s for security, upholding copyright regulations, or a deliberate attempt to restrict access to the internet, they all use the same methods to detect and block VPN IP addresses. Here are the main ways they detect VPN usage.

• Deep packet inspection (DPI). This is common practice in countries with heavy internet censorship, like China and Iran. Since your VPN traffic is encrypted, they can’t see any of your data, and therefore can’t block you from news or social media sites that don’t meet government standards. Instead, they try to identify and block all non-government–sponsored VPNs, and they do that through deep packet inspection. The way it works is they use metadata to analyze packets of information, looking for patterns that match those of common VPN protocols. Using obfuscated servers helps you evade DPI by making your VPN traffic look like regular internet traffic.
• IP addresses. VPNs often use shared IP addresses, which can be a dead giveaway that it’s a VPN server. If an unusual number of users are signing in from a single IP address, the platform will suspect it’s a VPN and will impose an IP block. Using a dedicated IP address will help protect you from getting blocked for using the same IP address as others. Another telltale sign that you’re using a VPN is if the IP address is associated with a data center instead of a residential IP, which will also lead to an IP block. Switching to a different IP address is an easy way to get around a specific VPN IP address block.
• VPN protocols. Every VPN protocol has a unique pattern that platforms are on the lookout for. If a website, government, or school picks up on one of these patterns, it will block all the traffic coming from that server. Obfuscation makes VPN traffic look like regular internet traffic, so you can avoid detection. That’s why it’s important to use a high-quality VPN that offers obfuscation.
• Port blocking. VPN traffic is typically sent through specific ports, and companies can block these ports to restrict VPN connections. You can avoid port blocking by choosing a port that is unlikely to get restricted due to the detrimental impact it would have on other internet traffic, like port 443.
• DNS cache and filter. When you are trying to get onto a website, it may go to the network DNS server before getting directed to your VPN. The DNS server will cache the site before you’re VPN gets a chance to unblock it. This is a common problem when using a school or work network. Activating IP & DNS leak protection on your VPN can help evade detection.

Why do websites and services block VPNs?

Using a VPN is one of the best ways to protect yourself from cyber threats online, so it’s pretty frustrating that so many websites and services block VPNs, but it’s not without reason. Here are the main reasons VPN blockers get put into place.

• Copyright enforcement. Many people use VPNs to bypass geo-restrictions on streaming sites like Netflix and Hulu. It’s a great way to expand your library of movies and TV shows, but it also has legal implications. Streaming services purchase region-specific licensing agreements for their content, and they are obliged to do whatever they can to uphold these agreements, or they can face legal consequences for copyright violations. That’s why they make every effort to block VPN IP addresses that may be used to access content outside of their region.
• Academic integrity. Network administrators in schools use VPN blockers to maintain a proper academic environment. Schools have firewalls in place to prevent students from accessing inappropriate content, illegal sites, gaming platforms, or questionable journals.
• Since VPNs send all your data through an encrypted tunnel, they can be used to get around the school’s firewall, allowing students to enjoy full internet access without getting detected. Schools make every effort to block VPN connections so they can create their desired academic environment.
• Managing Internet traffic. There is a limit to how much data any network can handle, and VPNs use up a lot of bandwidth, especially if they are being used for gaming, streaming, or torrenting. Internet service providers often use bandwidth throttling to control the amount of data passing through their system at any given time.
• Since VPNs are encrypted, it’s impossible to see how much data is being used up, making them a great tool for avoiding bandwidth throttling while engaging in data-heavy activities like gaming.
• That’s why network administrators at schools, office places, and even internet service providers will block VPN connections. It’s a necessary measure to prevent an overload of internet traffic.
• Security. While using a VPN is the best way to stay safe from cyber threats for individuals, aVPN IP address can be used to hide your identity and commit fraud, making the very tool designed to protect your online security, a tool for cybercriminals to spread malicious content. Companies make an effort to block VPN IP addresses so they aren’t vulnerable to VPN enabled cyber attacks.

Why do schools block VPN usage?

Schools block VPNs because they want to keep their students focused on academics and off of sites that are inappropriate for an educational setting. They also want to keep their networks running smoothly and securely. Here are the main reasons why schools want to block VPNs:

Content management

Schools are meant to be a safe environment where students come to learn. That’s why most school networks set up firewalls to keep students off distracting or inappropriate websites. Gaming sites and streaming platforms are typically off limits on school networks.

A VPN can be used to get around these school firewalls, threatening the academic environment the schools strive to create, so they set up VPN blockers to prevent that from happening.

Managing bandwidth

Internet service providers can only handle so much internet traffic at once, and schools want to be sure academic uses get priority over gaming, streaming, torrenting, and other non-academic data-heavy activities.

Since VPNs encrypt your data, schools can’t see how much bandwidth you are using up. When students use a VPN to get around the school’s firewalls for data-heavy activities like gaming or streaming, the school network can get overwhelmed and won’t work efficiently.

That’s one of the reasons schools implement VPN blocking as part of their bandwidth management strategy. It ensures that their allotment of bandwidth is used for learning purposes.

Security

Schools hold on to lots of sensitive data, like health records, home addresses, phone numbers, and even financials, and they must keep this information secure. VPNs make it easier to spread viruses, malware, and phishing attempts that could compromise the school’s security systems designed to protect this information. It’s another good reason for them to block VPNs.

How VPN detection works in restricted countries 

Countries with internet censorship, like China and Iran, restrict access to news sites, social media platforms, browsers, and more, so they can control the messaging that their citizens are exposed to. Some citizens and travellers in these countries use VPNs to bypass these restrictions so they can have full, unrestricted access to the internet. To prevent that from happening, these governments are on a constant lookout for VPNs using the following methods:

Deep packet inspection (DPI)

Deep packet inspection is a common method used for VPN detection in restricted countries. DPI looks at every data packet traveling through its network, inspecting the data packet’s size and timing, while searching for common VPN protocol patterns that can identify VPN usage. So, even though your data is safely encrypted in a VPN tunnel, DPI can still tell that you are using a VPN.

The best way to get around DPI is with obfuscation, which disguises VPN traffic to look like regular internet traffic. Only the best VPNs have all the necessary features to avoid VPN detection in countries that use deep packet inspection.

IP blocking

IP blocking uses lists of known VPN servers compiled by governments and ISPs. Then they simply block internet access to anyone using one of those known VPN IP addresses. Using a dedicated IP address, which is your own VPN server, in place of a shared IP address, can make it harder to detect that you are using a VPN and will help you bypass VPN blocks based on IP addresses.

Port blocking

Restrictive governments and ISPs know which specific ports are commonly used by VPN clients. For example, OpenVPN typically uses port 1194. Blocking access to these ports is an easy way to block VPN connections from getting through. In some cases, instead of completely blocking access to the port, they may also throttle all VPN traffic going through that port, which slows down the connection so much that it becomes ineffective for most online activities. Switching to a different port, like port 443, can help you avoid port blocks. Port 443 is essential to many businesses and services, so it’s not going to get shut down or throttled.

VPN bans

In some countries, like China, Russia, and the UAE, using a non-government-approved VPN is against the law. Using an approved VPN requires you to agree to government restrictions and surveillance, while using a non-government VPN puts you at risk for heavy fines or jail.

Why staying undetected matters

Here’s why keeping your VPN connection undetectable is so important.

• Internet freedom in restricted countries. If you’re in a country with restricted internet access and limits on VPN usage, you could face heavy fines or jail time if you get caught using a VPN illegally.
• Avoiding school and workplace firewalls. If you want full internet access at school or work, keeping your VPN unblocked is key. Network administrators block VPN connections, and you could get in trouble with your school or employer for using a VPN to get onto restricted sites.
• Freedom of speed. For journalists and activists trying to get the truth out in restrictive environments, a VPN is essential, and keeping the VPN undetectable is crucial for anonymity and safety.
• Unblocking streaming services. VPNs are a great tool for bypassing geo-restrictions on Netflix, Hulu, and other popular streaming platforms, but if they detect you’re using a VPN, it’s not going to work.
• Privacy and security. A quality VPN is the best way to maintain a secure and private internet connection, and making your VPN use undetectable makes it even more secure.

How to make a VPN undetectable

The first step in making a VPN undetectable is subscribing to a premium VPN service with built-in features, like obfuscation, to prevent VPN detection. Then here’s how you’ll want to set it up:

• Use port 443. This port is rarely blocked, since so many organizations and services depend on it. This port works with the OpenVPN TCP and SSTP protocols.
• Use obfuscation. Some VPNs, like ExpressVPN, already have obfuscation set up on all of their servers. Other VPN services require a little bit of setup. With NordVPN, choose obfuscation under specialty servers, and with Surfshark, turn on obfuscation and use the Camouflage Mode.
• Select secure VPN protocols. The best VPN protocols for avoiding detection are OpenVPN and WireGuard. ExpressVPN and NordVPN’s proprietary protocols, Lightway and NordLynx, are WireGuard equivalents and will get the job done as well.
• Use a dedicated IP address. While you’re trading off some of your anonymity, dedicated IP addresses are rarely blocked. Since they aren’t shared, they don’t get flagged for having an unusual number of users coming from the same IP address.
• Disable location services. If your GPS or location services don’t match up with your VPN IP address, it’s a dead giveaway that you are using a VPN, so you’ll want to turn those features off. It’s also a good idea to clear your browser cache, which can reveal your true location.
• Use an SSH tunnel. This lets you send your VPN traffic through another device, which lets you get past blocks. For example, you could route your school computer through your home network. The downside is it will slow your connection down and could impact online performance, especially for activities like gaming or streaming.
