Unexpected Vulnerabilities with Your Firewall Device and How to Handle Them

May 7, 2025

An essential component of your company’s network security, a firewall device is a must to defend against modern cyber threats. This is especially true when it comes to the corporate world, as vulnerabilities and risks can be pretty substantial.

While firewall solutions can be more than thorough for the sake of your network security, they aren’t 110% devoid of vulnerabilities. Not only is it important to know what those are, but what can be done about them as well.

Between being proactive and having the right security policies and features in place, there’s a lot to be prepared for. For this article, you’ll get a direct understanding of unexpected vulnerabilities that you might encounter with your firewall device.

Common Vulnerabilities with Your Firewall Device

A lot of this comes down to the type of firewall tech you’re working with. Some can encounter more security risks than others, depending on a variety of factors. While the threats of cyber security are immense, some are more common than others in the realm of firewall tech.

Here are a few common vulnerabilities that every business should look out for:

  • Outdated or unpatched firewall firmware
  • Zero-day risks that pose a threat before a fix is readily available
  • Lack of multi-factor authentication
  • Hidden access points in firmware due to being outdated or not properly secured

It’s important to remember that digital threats tend to look for any opening they can. In many cases, these vulnerabilities become active risks because something was overlooked in the architecture. Without thorough network firewall security, your business will always be open to digital threats like this.

How Your Network Security is Exploited

Any time you face a network security threat, the next thing that likely comes to mind is: how did it happen? Your network can be exploited in many different ways, but once again, there are a few common examples.

First and foremost, it’s helpful to understand that someone might simply choose a brute-force attack. This isn’t as tactful as other examples and generally includes exploiting weak passwords or surface-level security measures.

Aside from that, many of the major breaches you read about stem from a deeper layer of network security. Primarily firewall vulnerabilities, as this is a good way to gain access to the entire network. In short, digital threats like this will look for any vulnerability to make their way in. 

There’s plenty you can do to be proactive, but this also requires a decent understanding of the risks at hand. Whether you have a dedicated security team or not, it’s crucial to have every layer of your network protected.

Let’s Wrap Up

Your approach to network security doesn’t have to feel nerve-wracking, but it’s essential to be thorough. Different types of firewalls will come with unique varieties of security features. 

Not only do you need to make sure your bases are covered, but you’re consistent with network maintenance and hardware upkeep. If you ever feel like you could use a hand in your network security setup, the Firwalls team is here to get you started in the right direction.
