VPN Working Methods:

The three main methods that are done by the VPN to hide your personal information,

  1. Hides your IP address
  2. Routes your data through a secure tunnel
  3. Encrypts your data with good encryption method

1.Hides Your IP Address

The VPNs hides your IP address by routing your internet connection through another channel which encrypts all your data and sends it through another IP hiding your real IP.

2. Routers Your Data Through a Secure Tunnel

All the data packets that are passed through the VPN results in encrypted packets that are hard to trace he origin and thus hiding the original IP address of the sender.

3.Encrypts Your Data With Good Encryption Method

Every data that is sent and received within the VPN tunnel are highly encrypted and is difficult to break so that it helps in secure transmission inside the VPN.

Types of VPN Encrypts:

  1. SSL
  2. L2TP / IPSec
  3. SSTP
  4. IKEv2 / IPSec

1. SSL – Secure Sockets Layer

SSL is secure sockets layer which is introduced to transmit the data in an encrypted form. It transfers the data from one place to another in an encrypted form. First the ssl checks the connection between the both ends and verify that they are authentic sources. Then it establishes a connection between them.


Layer 2 Tunneling protocol is one of the tunnelling protocol that is used in the VPNs. This protocol is used to transfer the data by the ISP provider. And also for the Tunneling purpose it uses an encryption algorithm that helps to prevent from the unauthorised access.


Secure Socket Tunneling protocol is one of the most used and most important VPN protocols. It is developed by the Microsoft for the purpose of distributing with its Vista operating systems and it’s higher models. It has lot more features so that it is considered best compared to the other VPNs for windows. It is highly recommended for windows.


IKEv2 means Internet Key Exchange v2 and IPSec stands for Internet Protocol Security Suite. These both together forms the best VPN protocol. This type of VPN protocol is non breakable and very much reliable. So that many of the popular VPN companies are using this protocol.

How To Get a VPN?

There are a lot of VPNs available in the market. Most of them are commercial ones. Also there are many open source VPNs available. Commercial ones are the best because they are well maintained and are less used for spamming purposes. So if you need a VPN for highly confidential data access with good support then I strongly suggest you to move to the commercial VPNs. Also we do not recommend VPNs for any kind of illegal activities.

Benefits of VPN:

There are a lot of benefits for VPN usage. Some of them are listed below.

  1. Protect your online identity
  2. Access some of the content in the internet that are blocked specifically in your country
  3. Prevent unauthorised access to your network

Google displays search results according to the country IP address that your device uses. So different country have different results. As an SEO myself I use VPNs to distinguish myself as a user from the other country and check the results that are displayed in that country.

Setting up VPNs on devices:

  1. Mac devices
  2. iPhones

Is VPN Safe?

This question is answered by looking on to VPN you have chosen to use. A good commercial VPN will help you fulfil all your requirements and safe guard your data well and good.

Also you can create your own VPN with good security practises.

Is VPN Legal?

Yes of course. It is legal unless or until you decide to use it for your illegal activities such as hacking, data stealing etc. Even though the VPN is anonymous it still can track you down. So it is highly recommended not to use your VPNs for any illegal activities. It may lead to get caught.
