How Does a Firewall Protect Data?

Did you know around 15 million data breaches were reported in the third quarter of 2022? The increasing threat of cybercrimes has made data security a priority for every business operating digitally.

Implementing robust technology that can guard your network and data from unauthorized access has become important, more now than ever. A firewall is one such way to protect your data and mitigate the risks of breaches within your organization. Your IT help desk can help you implement a firewall for network security.

In this post, we’ve explained the firewall, how it protects your network, and why every company should consider investing in it. Read on.

What Firewalls Do?

Think of a firewall as a guard standing by your company’s entrance and guarding your property against intruders. They scan and verify the IDs of each employee before letting them in. That’s what a firewall does for your organization.

It guards your network against outsiders. It allows seamless communication among the company’s internal members or authorized users but blocks access to a third party. On an individual level, a firewall offers protection against a hacker who might be trying to launch a malicious application on your system.

According to Business Wire, the firewall market is expected to grow by $304 billion by 2026. The market will keep growing as there’s an increasing demand for network security. Let’s check out a few ways firewalls protect your network.

How to Use a Firewall?

Most businesses outsource their network security and all technical operations to a reputable IT help desk. These organizations implement robust tools, including firewalls, to protect the company’s network, employees, and clients’ confidential information.

The firewall must be set up correctly and maintained well to improve your network security. Here’s what may help.

Your firewall must be up-to-date with the latest updates, especially against recently discovered threats.
Use a firewall that offers built-in antivirus programs (or download antivirus software separately) to protect your system against viruses.
Limit your traffic access to trusted source addresses.
While a firewall is quite effective, it can’t help you recover lost data. You must have a data backup plan in place and an active network.

Bottom Line

You need robust defensive technology against malware attacks, viruses, insider attacks, and other tech-related vulnerabilities. As IoT has become mainstream, the security tools that keep your network safe have become essential. If you are unsure about firewall installation, contact IT service providers for assistance.
