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.
