VPN vs Firewall

What is VPN?

The term VPN refers to a virtual private network. It's a kind of private network that's also virtual. We can use a public network as a private network since VPN is a technique for handling encryption, integrity protection, and certification or authentication. On a public network, it gives the appearance of a private network.

What is a firewall?

A firewall is a network security device that examines all incoming and outgoing network traffic. Based on a defined set of security criteria, firewall devices whether to accept or prohibits traffic. They serve as the network security system's initial line of defense, forming a barrier between secured and controlled internal networks.

VPN vs firewall | Difference between VPN and Firewall:

  • A VPN can't create security rules or block data packets from entering your machine. If there is a problem connecting to the VPN server, some VPN clients may have a killswitch feature that disables internet access. However, this merely protects you from accidentally exposing your true IP address.
  • A firewall lets you configure the way your computer communicates with the internet by setting your own set of security rules, which prevents malicious traffic from entering your device.
  • VPN encrypts your internet connection, ensuring that no one can track your online activities or steal sensitive information like account credentials or credit card numbers.
  • While a firewall cannot assist you to avoid geographical restrictions so that you can access any content online even if it is not available in your country, a VPN can. Only websites that can be visited from your computer are restricted by the firewall.
