A VPN is a network of devices that communicate via secure channels but still use the ordinary internet. The essence of a virtual private network is that the devices that form the network can communicate with each other secretly by encrypting the messages and channelling them through secure channels. Thus, third parties can neither detect nor access the communications that take place among VPN devices. The following are some of the reasons as to why you should use a VPN when communicating.
1. To secure your communication
At the basic level, a VPN helps you to secure your communications. All VPNs work by first encrypting the traffic that clients send and receive when online. The servers of the VPNs then send the messages through tunnels that third parties cannot access. This process is usually complicated. To achieve this objective of securing your communication, VPNs use equally sophisticated encryption protocols.
There are many encryption protocols currently in use. The choice of the protocol that a VPN service uses depends on the extent to which the company operating the service would like to secure your communications. Some companies use advanced encryption protocols such as the most advanced forms of IPSec and OpenVPN protocols.
However, other VPNs use common protocols such as PPTP in addition to the advanced forms such as L2TP, IPSec and OpenVPN. What is important to note is that encryption protocols help to secure your communications. This feature makes a VPN the best tool you can use to keep your messages safe and away from unauthorised persons.
2. To avoid the vulnerabilities of Public WI-FI networks
Many public Wi-Fi networks are insecure. There are many ways in which hackers can successfully infiltrate a public Wi-Fi network and hack into the devices that are using the network. Now, it is likely that at one point or another, you have to use a public Wi-Fi network. This occurrence is particularly common when you are travelling.
The problem is that you need to secure your data and even device when you are using such networks. A VPN provides the most efficient method that you can use to secure your data and device when using a public Wi-Fi network. A VPN service not only makes you anonymous when you are online but also protects you against common forms of malware and attacks. Therefore it is wise to connect to the internet via a VPN whenever you are using a public Wi-Fi network.
3. To avoid any form of interception
The need to prevent detection is another important reason as to why you should use a VPN when communicating. At certain times, government agencies may attempt to intercept the communications of private citizens. Although this does not happen quickly, if you happen to be on the radar of any law enforcement agency, it is possible that the government may attempt to intercept your communications. Interestingly, many governments nowadays are wary of dissidents and may employ sophisticated surveillance methods to intercept the messages that dissidents send and receive.
The solution to the problem of third parties intercepting your messages is to use a VPN. If you are an activist or even a journalist doing sensitive work, you may find it prudent to secure the messages that you send and receive. The best thing you can to avoid getting into trouble with government agencies is to use a VPN every time you communicate.
A VPN will hide your IP address and encrypt your messages. As a result, government agencies intent on intercepting your communications will not determine your locations. Also, it will be almost impossible for third parties to hack into your inbox or access your messages in any other way.
4. To remain anonymous when you are online
A VPN, unlike a Smart DNS, gives you an entirely different IP address. Therefore, when you use a VPN, third parties cannot determine your real identity. There are many instances in which you may wish to remain anonymous when you are online. For example, when you are accessing P2P file sharing sites, it is wise to remain anonymous.
Also, you may have to hide your IP address when you are using some of the VOIP services. Either way, the need to hide your IP address is another important reason as to why you should use a VPN when communicating.
In conclusion, there are many reasons as to why you should use a VPN when communicating. However, in summary, you need to use a VPN to hide your IP address, avoid possible interception of your messages and secure your data when using a public Wi-Fi network. Also, you should use a VPN to enhance your level of digital security.
