You've probably heard of firewalls and VPNs. While both protect your devices from cybersecurity threats, the ways by which they do so are vastly different. Both are vital for your security, and in this article, we'll go through the differences between a firewall and a VPN.
Here we go...
As the name suggests, firewalls serve as a barrier between your device and your network. Their role is to "scrutinize" and "verify" all traffic that enters and exits the network. It's a device with powerful centralized management and reporting capabilities that prevents unauthorized users from accessing private networks connected to the Internet.
If a threat is detected, the user will be notified, and traffic will be blocked until the user confirms that the danger is real. Windows Firewall comes preloaded with the operating system. When you install new software on your computer, you may receive a notification that a program is attempting to access your computer and that you must allow permission. That's how the Firewall works.
There are two types of firewalls, a network firewall, and a desktop firewall. A desktop firewall is a type of software, while a network firewall is a type of hardware. Installing a firewall will help you protect your private network from security breaches. When used in unison, firewalls dramatically lower the likelihood of hackers and phishers penetrating your computer or network.
A virtual private network, famously known as VPN, encrypts all of your device's traffic instead of putting up a barrier between your device and your network. Your data is encrypted, making it unreadable to everyone else on your network, including the government.
VPNs allow you to connect to another private network 'virtually' and frequently, as well as encrypt your connection with technologies like IPSec. VPN masks your IP address when using public wifi by routing your internet connectivity through a remote server, safeguarding you from attempts to get your data or location.
These days, it’s good to have both a firewall and a VPN to have complete protection from cybercriminals.
