VPN vs Antivirus and Firewall


A common question arises in the mind of the user is whether he or she needs a Virtual Private Network even if he or she has firewall and antivirus installed in their system. The answer to this question is a resounding yes. Antivirus and firewall can prevent the system from the simple security problems like e-shopping.

Firewall controls the incoming and outgoing traffic of data. Firewall will not allow a data coming from unauthorized site. But it does not discriminate the type of data transferred through the net therefore you may have downloaded a file with virus. Here comes the necessity of using the VPN or Virtual Private Network.

Antivirus detects the virus and eliminates it. Antivirus detect only those virus which available on their list. Every day the list of virus is increasing therefore one need to update the list constantly in order to protect the system. Therefore the use of VPN is increasing with each passing day.

VPN stands for Virtual Private Network. VPN helps to protect our IP address from hackers and the prying eyes lurking behind our back. We use internet for our work whether we are at home or in the office. VPN can create a virtual office. Through VPN one can access from the remote places or the comforts of their home to their office. VPN enables us to work to our highest potential.

VPN or Virtual does much more than protecting our system from the virus. It allows us to work in between the unprotected network. We often access internet through Wi-Fi network in the public environment. It makes us susceptible to the danger of the worldwide web. If you are connected to the system through the Virtual Private Network, then even if the hacker can access your data they will not be able to retrieve the data as it is protected through the encryption and the protocols. There are mainly three protocols used in the Virtual Private Network. They are Layer two tunneling protocol, Internet protocol security or IPSec and Point to point tunneling protocol.

Many of the users may want to visit a certain website without letting the person running the website knowing the real IP address of the user. VPN masks the IP address with another IP address. Virtual private network has several servers throughout the world through which they bounce the IP address therefore the detection of the real IP address becomes impossible.

VPN or Virtual Private Network also enables us to see the geolocation restricted sites of UK and USA. These geolocation restricted websites are only available in Britain and USA. They produce high quality programs which is popular throughout the world. These websites monitor traffic to their server in order to block certain websites which are originating from outside the country. With the help of the VPN, the user can see these restricted website whether they are travelling or staying in a foreign country. There is BBCiPlayer,40D, LoveFilm etc in UK and Netflix in USA.  VPN enable us to visit these sites through masking the IP address with an IP address originating from within the country.

There are various advantages of using the Virtual Private Network in comparison to Antivirus and the Firewall.
