You may have heard of VPNs before, especially in terms of improving online privacy, but what do you really know about them? If you are not sure what a VPN should provide, or you are not sure, a VPN is definitely not. A virtual private network or VPN is just a group of computers, which are usually connected remotely through an encrypted tunnel to share files and resources. VPN blocks your IP address, so your online activities are almost impossible to track. It is important to note that VPN services establish a secure and encrypted connection to provide greater privacy than secure Wi-Fi hotspots. If it is still not clear, the obvious reason you need a VPN is to maintain your privacy online. Whether you send emails via email, shop online, or pay bills, a VPN can protect your online activities. A VPN can also help you stay anonymous while browsing the Internet. Five things to consider before investing in a VPN.
The VPN server is also called an exit node and is one of the most important aspects of VPN. When you connect to the VPN, your data packets will leave the server through this exit node. This has two important advantages. The URL and content exchange of the visited website. Second, provide the IP address of the location for these packets and create a new virtual location for it. To simplify the connection, you also need exit nodes in certain geographic areas that require virtual locations. The more servers a VPN has, the more difficult it is for content providers and countries to block them.
2) VPN protocol
There are many VPN protocols out there, and it may be difficult to narrow the list down to what you need. Of course, you should choose to provide easier connections, faster speeds, and more secure encrypted connections. OpenVPN is one of them. The most popular protocol in the VPN field. In addition to using 256-bit AES key encryption, it is also open source. This means that users anywhere can look closely at the code to find vulnerabilities. L2TP / IPSec L2TP is a combination of L2TP and IPsec security protocol. It uses secure 256-bit AES encryption, but it relies on a single port, so it is easy to block. Other known acceptable protocols include SSTP, IKEv2, and WireGuard. With the development and increase of the number of VPN protocols. This list will of course be expanded
VPNs, especially free VPNs, usually have data restrictions. If you are streaming or downloading a large amount of multimedia content, the bandwidth requirements will be higher. In addition, if you use a VPN on a mobile device, you can use a large portion of the bandwidth for browsing services. Therefore, please make a decision based on your data needs.
4) Useful functions
It is always nice to be familiar with some of the most useful functions of a product or service. For a VPN, the most useful feature is the one that ensures that you remain anonymous and privately online, even if you forget to turn it on or you will not notice it when the network is interrupted. When you connect to an insecure network, “Auto Connect” will automatically start the VPN. For example, this can help prevent personal information from being sent over public Wi-Fi networks. If the VPN connection is interrupted, the kill switch will also interrupt the network connection. This feature is especially useful if the network connection is unstable or the device has been connected to the VPN for a long time and you as a user cannot always sit in front of the device. In short, these features can provide protection in the event of a problem. That’s all you need.
You may not even need a full VPN. You may only need a VPN proxy, which is actually a forwarder that will be inserted into the data packets and provide them with different IP addresses. The contents of data packets or DNS addresses, but make them faster, cheaper, and easier to use, which is why they are particularly common in free VPNs for mobile devices. In short, a VPN is a major investment, especially if you care about your online privacy. As with all types of investment, it is important to conduct research in advance. First, look for any useful servers, VPN protocols, data restrictions, and functions. You are buying a VPN. Depending on your situation, you may only need a simpler and cheaper VPN proxy.
