How effective are firewalls in preventing data breaches?

Oland Wasmer

A firewall is a type of security system that is designed to keep your computer and network safe from cyber-attacks. It works by blocking unauthorized access to your computer or network by blocking access to certain ports or restricting access to certain websites or services.

In general, firewalls are very effective in preventing data breaches. They can help protect your computer and network from hackers, viruses, and other types of cyber-attacks. However, it's important to note that no firewall is 100% effective, and hackers are constantly finding new ways to get around them.

So while firewalls are a great way to protect your computer and network, it's also important to practice safe browsing habits and install other security measures, such as antivirus software, to make sure you stay safe online.
