These days, it’s tough to keep yourself private on the internet. From social media websites to online shopping platforms, your data is stored and potentially used to curate advertisements. If you’re interested in browsing the web more privately, take a look at this guide and learn more about how virtual private networks (VPN) can help.

What is a VPN, and how does it work?

VPNs

A VPN is a service that creates a secure connection over a public network. VPNs are often used to protect your privacy online and connect to remote networks. When you connect to a VPN, your computer establishes a secure connection to the VPN server. This connection is then used to route all of your traffic through the VPN server. Because all your traffic is routed through the VPN server, your true IP address is hidden from the websites and services you visit. This means that if you’re on vacation in Spain but want to watch content restricted to only American audiences, you can use a VPN to connect to an American-based server and bypass the region’s restrictions. Similarly, if you’re living in China but want to access Facebook or Google, you can use a VPN to spoof your location and access these sites despite their blocked status in China.

When picking a VPN service, try to find a reputable one. You may also want to consider the cost.VPNs often cost a monthly subscription, but many are free to use. If both matters concern you, you can compare the most popular options in your country. For example, when comparing NordVPN vs ExpressVPN, compare specific features like access to geo-restricted content, server count, and customer service quality. You’ll need to download and install a VPN client on your device to set up a VPN. Then, simply enter your VPN’s username and password, select a server, and hit connect.

What are the different types of VPNs?

Several different types of VPNs will suit your needs more than others. Site-to-Site VPNs connect two LANs (local area networks), typically at various locations. The two LANs are connected by an encrypted tunnel, allowing employees in one location to access resources on the other location’s LAN. For example, this could enable employees in your company’s London office to access files on your company’s server in New York. Remote Access VPNs allow employees to connect to their company’s network from anywhere in the world. These are often used by telecommuters who need to access their company’s network from home or while traveling. Remote access VPNs typically use either SSL or IPsec encryption technologies. If you’re new to VPNs, your best bet is to choose a VPN service with a great reputation. Be wary of free VPNs, as they may not be as reputable as you think.

IPsec Tunnel Mode is the most common type of remote access VPN, and it uses ESP (Encapsulating Security Payload) for encrypting packets between the client and server. ESP provides confidentiality, integrity, and authentication for data transmitted over an IPsec tunnel. SSL Tunnel Mode is similar to IPsec tunnel mode but uses SSL for encrypting packets between the client and server instead of ESP. This also helps keep you secure. PPTP Tunnel Mode is a remote access protocol that uses Microsoft Point-to-Point Encryption for encrypting packets between the client and server. PPTP provides confidentiality but not authentication, so it should only be used if other security measures are in place.

VPNs are an important tool for internet users to protect their privacy and security. A reputable VPN should be your top priority if you’re looking for a private way to browse the internet. Just follow these tips and choose a service that works best for you.
