When and Why to Use a VPN for your PC/Laptop

Things to Consider While Choosing a VPN service for your PC

If you require your data to be protected, the most likely solution you would have been given is to install a VPN. The VPN is a virtual private network and works by providing a channel between the internet and your computer, which provides anonymity online and encryption of data. When you have a VPN, there’s a buffer which is a server that comes with an IP address.

If you are working on a PC or laptop that is not at home, and are using a lot of Wi-Fi at public places, there is just no way for you to know how secure the network is. You could be traveling a lot with a PC/laptop rented from a computer rentals company, and want your data safe. That is when you use the VPN service; there are several such free services available, although the paid ones are faster.

Things to consider

Some of the VPNs block torrents so if you are planning to use the service for torrents, you should check that first. The VPN should be able to function on all your gadgets and not just the PC. Another aspect to consider is if the service has any limits on bandwidth.

You would want a network that has no limits on bandwidth. Before you get a service, you should also check on their privacy policy; does the VPN retain records of usage? If they keep logs and you are uncomfortable, you should research well before opting for a service. Also, make sure where the servers of the VPN providers are located. If the physical/geographic distance between the server and your PC is huge, the downloads will be slower. It is ideal to choose a service provider closer to your region.

There are four well known VPNs, including point-to-point tunneling protocol (PPTP), layer 2 tunneling protocol and internet protocol security (L2TP and IPsec), secure sockets layer (SSL) and openVPN.

PPTP: Not a very secure VPN step, but it is a good step from where you can start your VPN exploration.

L2TP and IPsec: Safer than PPTP, but are more complicated when it comes to setting them up.

SSL: VPN method which is more trustworthy and dependable than PPTP, L2TP or IPsec

OpenVPN: An open source system that is secure, free, and has no connection troubles.

If you need a VPN system that is more dependable than all of the above, you could try a VPN router. If you are seeking VPN just to safeguard your internet activity while on a public Wi-Fi, you could subscribe to a VPN service provider.
