VPN vs Antivirus and Firewall

Why you need a VPN?

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 a firewall and antivirus installed on their system. Answer to this question is a resounding yes, the Antivirus and firewall can prevent the system from the simple security problems like e-shopping.

Firewall:

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

Antivirus:

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

VPN:

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 the 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 the internet through the Wi-Fi network in the public environment. It makes us susceptible to the danger of the world wide 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. There 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 to hide their real identification. The 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 the UK and USA. These geolocation restricted websites are only available in Britain and the USA. They produce high-quality programs which are 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 websites whether they are traveling or staying in a foreign country. There is BBCiPlayer,40D, LoveFilm etc in the UK and Netflix in the USA.  VPN enables us to visit these sites by masking the IP address with an IP address originating from within the country.

Final Words:

If internet security is on your mind – and it should be on all our minds these days – antivirus software and VPNs are two of the best available protective measures, and they can and should be used together.
