Different types of security protocols for VPNs

Internet is a key part of the modern-day world. Most of the commercial as well as personal tasks, as mere as communication; cannot even be imagined without the use of the Internet. It has also become a virtual market and interaction place. However, being this vast, it also has specific issues when it comes to the part of security and access. In countries like South Korea, internet security and privacy are given specific importance. This is why residents there use VPN services like privacyforkorea. Here are the different types of VPN protocols that are prevalent in public service.

Internet Protocol Security

It is also referred to as IPSec. The protocol is meant for safeguarding communications based on Internet across a particular IP Network. It basically works on verification of the sessions and then on the encryption of each and every packet of data being used in the connection. There are two modes of running this protocol. One is the transport mode and the other one is the tunneling mode. While the transport mode encrypts the messages present inside the packet, the tunneling one encrypts the packet as a whole.

Tunneling protocol on a Point-to-point basis

This one is also referred to as PPTP. The job of this protocol is to generate a tunnel and then confining the data packets inside it. This is one of the only protocols that are used widely all over the world. This one has been in the safety scene ever since the time of Windows and it also functions well with Mac as well as Linux.


These two stands for Secure Sockets Layer as well as Transport Layer Security. These two generate a virtual private connection under which the browser becomes a client and is only restricted to using some of the apps instead of an entire network.
