How does a VPN Work?

After connecting to a VPN server, the software will start encrypting the data before your Internet Service Provider makes a note of it. Then, the data gets encrypted and goes to the VPN. From the VPN server, the data will reach the destination network. The Network can now only see your VPN Server’s IP address and location. Your personal IP and location get hidden by using a VPN.

If you are not using any VPN, there is a potential risk of data theft. If you are using a VPN, your data will enter the encrypted network which protects your data.

#2: After activating, VPN will start encrypting the data from your device. (Once the VPN is activated, your IP address gets hidden and you are not connected to a virtual IP address).

VPN Protocols

For any application, there might be a protocol followed to ensure standards. Likewise, VPN has also different protocols and all famous VPN companies follow any one of the protocol to maintain their standards in the VPN industry. Here are the most commonly used VPN Protocols:

#1: PPTP: PPTP is a Point-to-Point tunnelling protocol. It is one of the oldest protocols used. This protocol is now barely secure. The protocol was developed by Microsoft and it is very easy to set up on older computers. Don’t go for the VPN which follows only PPTP protocol.

#2: L2TP/IPsec: This protocol was the combination of PPTP along with Cisco’s L2F. L2TP protocol used keys to create a secure connection at each end of the tunnel but the execution of this protocol is not much safe. To improve the security IPSec protocol was implemented along with L2TP. But still, there is a debate that hackers have the ability to break this protocol and hence it is better to be avoided as well.

#3: SSTP: SSTP is Secure Socket Tunneling Protocol. This is another Microsoft built protocol. It uses the SSL/TLS encryption to establish connection. SSTP Protocol is one of the most secure solutions used.

#4: IKEv2 (Internet Key Exchange, Version 2): Another Microsoft protocol which added more security to its previous version. IKEv2 is the iteration of Microsoft’s protocol which was developed earlier to this. This protocol acts as one of the best security to your data.

#5: OpenVPN: OpenVPN protocol takes the best out of all the other protocols used earlier. It is an open source protocol and it works using SSL/TLS. As it is an open source protocol, it is constantly developed by plenty of developers across the world. OpenVPN is the best VPN protocol available out there.

If you are planning to buy a VPN service, then you can check the protocol version and go ahead if the VPN is offering you OpenVPN or IKEv2 protocols.
