So, you’ve gotten smart and decided to use a VPN to protect your privacy during your daily usage of the internet. You know that by activating the VPN you are essentially creating a shield which is preventing your location from being traced, keeping you safe from hackers, and giving you total anonymity. But do you know the difference between the different types of VPNs and which is the best to use? If not, you don’t need to worry. Below are some of the most common types of VPN around the world, and their advantages.
- PPTP VPN
PPTP VPN (Point-to-Point Tunneling Protocol) is the most widespread and commonly used VPN protocol that is available for consumers. It is very easy to use and even a beginner will be able to pick it up immediately. This is how it works – the remote user will connect to the VPN network by using their existing Internet connection, and once that’s done, they login using password authentication. The good thing about PPTP VPN is that you don’t need extra hardware and the add-on software is relatively inexpensive. The downside however to using PPTP, is that it doesn’t have an active encryption process, and it relies mostly on PPP (Point-to-Point Protocol) to provide the security feature.
- Site-to-Site VPN
Site-to-site VPN allows different websites that have their own network, to connect with each other and form a VPN. It’s almost the same thing as PPTP VPN, only that there is no “dedicated” line which is being used. One of the advantages of using Site-to-Site VPN is that unlike with PPTP, all of the routing, encryption/decryption is enabled by the routers on each end of the connection, and it could be hardware based or software based.
- L2TP VPN
L2TP stands for Layer to Tunneling Protocol. Again, it is similar in function to PPTP in the sense that it also has a disadvantage when it comes to encryption, and relies on the PPP protocol. However, one of the main differences between the two of these is that L2TP not only provides data integrity, but data confidentiality as well. These two advanced security protocols give an even larger edge over PPTP.
Another VPN which is easy to use and has its own advantages is SSL (Secure Socket Layer). It can be accessed by entering HTTPS using any web browser. When you use SSL, what it essentially does is create a secure and encrypted “session” from your browser to the application server which you’re attempting to access. One of the huge advantages that SSL has over the other types of VPNs is that it doesn’t need to have any software installed. You can simply access the client application through any web browser.
