A virtual private network (VPN) is technology that creates a secure tunnel between your device and the internet. Once the VPN connection is established, all of your data goes to a remote server and is encrypted before it leaves. Then the encrypted data is shot back to your device and decrypted there. This protects you from prying eyes that might try to steal your login credentials or other sensitive information as it travels over an unsecured Wi-Fi network.
VPNs have become increasingly popular for individuals because they add an extra layer of security to their online activities. But they aren’t the only way to keep your digital data safe. Other tools, such as zero trust network access (ZTNA), provide the same benefits but are designed to be more compatible with the zero-trust cybersecurity model that most large organizations have adopted for their networks.
In addition to protecting data in transit, a VPN encrypts the connections between your device and other devices or networks. This can help prevent eavesdropping and ensure that you don’t connect to a fake or malicious site or download malware. However, a VPN alone isn’t enough to guard against all types of cyber threats, such as ransomware, which is still very active in the wild and can infect your device even when you are connected to a VPN.
Some people use VPNs to get around internet censorship and firewalls that block access to certain apps and websites. One of the most popular VPN protocols is OpenVPN, which has a wide range of configuration options and works on Windows, macOS, Linux, iOS, and Android. Other popular choices include SSTP and L2TP/IPsec, which are secure but not as fast as OpenVPN. If you’re concerned about speed, consider using a VPN with UDP ports instead of TCP, which can reduce latency and improve gaming and streaming performance.
The best VPN for you depends on your needs and budget. If you’re an individual, a simple VPN with a single subscription fee might be all that you need. But if you’re an enterprise, you might want to choose a solution with more features or customization options.
Many people also use VPNs to stop location-based price discrimination, a practice that occurs when online retailers show different prices for the same product to different customers based on their device type and location. A VPN can make it look as if you’re connecting from a different country, which can help you get better deals and avoid inflated prices.

In the vast majority of countries, it’s legal to use a VPN to protect your privacy. But be careful if you live in a country that’s trying to regulate VPN use. For example, in China and Iran, it’s illegal to use VPNs. That doesn’t mean they won’t work, but if you use a VPN in those countries, you could be subject to fines or prison time if you’re caught. The good news is, most VPN providers offer easy-to-use apps that let you set up a secure connection in just a few clicks.
