What is the relationship between VPN and firewalls?

A virtual private network (VPN) and a firewall are two technologies that can be used to enhance the security and privacy of a computer or device’s internet connection. While both technologies serve similar purposes, they work in different ways and can be used together to provide even more excellent protection. Let’s break down the basics of VPN and firewalls and explore the relationship between the two. Know your network connections and feel secure with Fortinet firewall products!

A VPN service encrypts your internet connection and directs it to a server in your selected location. This can also be used to bypass censorship and access restricted websites while also masking the user’s IP address. A firewall is a network security system that keeps track of and manages incoming and outgoing network traffic by pre-established security rules. A firewall may be based on hardware, software, or a combination of the two, designed to block unauthorized access to a network while allowing authorized communications.

Interrelation between VPN and Firewall

While both VPN and firewalls can be used to enhance the security of a device’s internet connection, they serve different purposes and work in different ways. A VPN encrypts and routes internet traffic, while a firewall monitors and controls incoming and outgoing traffic. However, they can be used together to provide even greater security.

For example, if a user connects to the internet through a VPN, all of their internet traffic is encrypted and routed through a server in a location of their choosing. This makes it much more difficult for anyone to intercept and read their internet activity. However, if the user’s device is not protected by a firewall, it could still be vulnerable to cyber-attacks.

By using a VPN in conjunction with a firewall, users can enjoy the benefits of both technologies. The VPN provides encryption and anonymity, while the firewall adds an extra layer of protection by monitoring and controlling incoming and outgoing traffic. This can be especially important for businesses, which may have sensitive data that needs to be protected.

It’s worth noting that while both VPNs and firewalls can be effective in enhancing the security of a device’s internet connection, they are not foolproof. Users must regularly update their security software and be cautious when browsing the internet to ensure that their device is as secure as possible.
