VPNs and firewalls are frequently used, a firewall and a VPN serve different functions and offer distinct advantages. The blog is all about firewalls, VPNs, and Firewall Vs VPNs. 

Firewall: 

A firewall keeps an eye on all network traffic, both coming in and going out. It serves as a barrier that either allows or blocks data packets based on pre-established rules, separating your device from the internet. Malware, illegal access, and other dangers can all be avoided by using a firewall to shield your network or device. 

You can specify security settings for what you let onto your network or machine by using firewalls. Two types of firewalls exist:

1. Hardware Firewalls:
   Physical devices that stand between your computer and the internet are known as hardware firewalls.
2. Software Firewalls:
   Software firewalls can control how programs on your computer behave and how you access the internet.

Virtual Private Network (VPN): 

VPN conceals your IP address. It protects you from those attempting to locate you or obtain other sensitive information by rerouting your network connection through a distant server. When using public Wi-Fi or working remotely, choosing the best VPN service is necessary since it encrypts your traffic and safeguards your data while it’s in transit. By rerouting your traffic through the server and hiding your IP address and location, it appears as though you are accessing the internet from a new location. Using the best VPN service can let you access content that is blocked or censored, maintain your privacy, and get around geo-restrictions.

Firewall Vs VPN:

The two carry out various tasks related to network security. Firewalls and VPNs can be used in combination to strengthen your digital security by removing dangers such as hackers, breaches, and insecure networks. But you have to do is take into consideration these elements:

Primary Function: VPNs’ main purpose is to increase data transmission security and privacy. Conversely, firewalls work to keep unwanted access and malicious traffic out of your network. 

Level Of Protection: Firewalls monitor and control network traffic but do not provide end-to-end encryption, whereas VPNs provide end-to-end encryption, protecting data in transit.

Layer: Whereas a VPN operates at the application layer, a firewall operates at the network layer. 

Data Encryption: A VPN encrypts your data and modifies your IP address, whereas a firewall does not.

Security: To thwart attacks, a firewall employs restricted network access and specialized security settings. Your location and private data are hidden using a VPN.

Connection: On public networks, a firewall keeps your device safe from illegal connections. When using public Wi-Fi, a VPN protects your device from data theft.

Network Restriction: Firewalls can be configured to either grant access to limited material or to block access to specific websites and services. Network limitations cannot be enforced through VPNs.

Geo-Blocked Content: Unlike firewalls, VPNs can get around content restrictions and geo blocked websites.
