What exactly is the deciding factor behind the point at which it needs to be replaced? Is it how long it has been since you installed it, or after a regular interval for no particular reason? The answer is not as straightforward as you think it is. In fact, if you ask ten different IT managers the same questions, you might get as many different answers. You will come across people who replace their firewall every couple of years, just as the ones who haven’t done that since installation, which might be half a decade ago.
The truth is, rather than a fixed date on a calendar, firewall replacement is about the performance and support it offers, along with whether it can keep up with the threats coming at it. So, this does not mean that you need to replace your firewall every two or three years. This also does not mean that you can leave the device as it is for six or seven years without any upgrades, just because you think that it is working fine.
So, based on these insights, how long can we safely rely on our firewall? What kind of consequences should you expect from stretching its lifespan? This article answers all these questions and more, including why it is extremely important that you work with the right firewall supplier, such as Switch Link Computer Trading, and you will know exactly when you should replace your firewall by the end of it. Happy reading!
Does Firewall Age Matter?
Devices age as time goes by. You must have seen the printer or scanner in your office wear out physically. But it is not the same in the case of a firewall. Firewalls age in a different way. For example, the processing power that seemed really fast in 2019 could be seen struggling to inspect encrypted traffic seven years later, in 2026. Once a model reaches the end of its life, the threat intelligence databases will stop getting meaningful updates, and vendors will stop patching up vulnerabilities on older hardware eventually.
With Dubai and Abu Dhabi being areas with some of the highest rates of connected devices and cloud adoption in the Emirates, it gives too many entry points for attackers, making this whole thing matter to UAE businesses way more than you think. Even if you don’t realize it at the moment, an outdated firewall sitting at the edge of that network is a risk that keeps on growing until something goes wrong and you are not ready to deal with the impact.
3 to 5 Years: The General Rule
Although people might think that it is just marketing, this period is considered the general rule to replace your firewall since it reflects the speed at which processing demands, encryption standards, and attack methods evolve. This is why the majority of cybersecurity vendors, especially the ones that are considered reliable, design their firewall appliances with a practical lifespan of three to five years.
- Years 1-3: The first three years, the firewall runs very efficiently. It handles current threat volumes without strain and also receives full vendor support.
- Years 3-5: This is the period when performance slows down a little. This will especially be noticeable with SSL inspection and high-bandwidth applications. The vendor support may be reduced to paid only or a limited number per year.
- Above 5 years: The device is approaching or has reached its end of life after 5 years. You will understand this when the firmware updates stop or slow down significantly. This period indicates the point at which you need to talk to a firewall supplier about a new plan.
That said, this number is not rigid and can change depending on how the firewall is actually used. This is where the next section, where we discuss the rest of the factors that decide a firewall’s timeline, becomes relevant.
What are the signs your firewall needs an upgrade sooner than you think?
Age most certainly is one indicator that says you need a new firewall. However, the practical signs below matter more in any context.
- Slower network speeds during peak hours: This is often the first sign that your firewall is slowing down too. You can check if your VPN connection is lagging or video calls are dropping when more staff log in. Such signs usually mean that the firewall is maxed out on throughput.
- Frequent firmware issues: If you are noticing frequent firmware crashes or other issues, it is a sign that your hardware is getting older. This happens because older hardware struggles to handle newer firmware builds, which in turn leads to instability.
- New compliance requirements: Certain sectors or industries, such as banking, healthcare, and government in the UAE, often require specific security verifications that older firewalls cannot meet. Meaning, if you work in any such sector, you would need to update your firewall whenever there is a new compliance requirement that the older version cannot meet.
- End-of-life notice from the manufacturer: When you receive such an end-of-life notice regarding your firewall, it means that the vendor is going to stop supporting the model. It also means that the security patches are coming to an end.
- Business growth: When your business grows with more branch offices, remote staff, and added cloud services, you will need a new setup, as all of these will increase the load on the existing one.
- Increasing cyber insurance premiums and other requirements: Unlike before, insurers are now asking for proof of updated security infrastructure as part of verification before issuing or even renewing existing policies.
Firewall replacement checklist: Before you replace anything
Ask these questions before jumping to conclusions about your firewall and making a rash decision regarding its replacement.
- Is the current firewall still receiving firmware and security updates from the vendor?
- Is the manufacturer’s support contract for the device expiring any time soon?
- Has network traffic increased significantly since the firewall was installed?
- Does the industry you belong to require specific compliance certifications that the current firewall setup does not support?
- Are your remote staff creating new access points that demand better VPN handling?
- Are you seeing consistent slowdowns during peak hours?
If your answer to all or some of the above questions is yes, it is time that you start considering a new firewall plan and approach a reliable firewall supplier such as Switch Link in the UAE.
Frequently Asked Questions
Generally, most firewalls have a practical lifespan of three to five years before performance and support start to decline. That said, in the specific context of UAE businesses, they might need a replacement closer to the three-year mark due to high traffic or strict compliance measures.
At Switch Link, we recommend the latter to our customers since repairs are rarely available once a firewall is a few years old. Any reliable firewall supplier would say the same as the manufacturers stop producing parts, and after a while, even paid support becomes limited. As per our research, replacing the device through a good firewall supplier costs less over time in comparison to trying to patch around an aging system.
The basic purpose of firmware is to help extend a firewall’s usefulness. However, they cannot fix hardware limitations like processing power or memory. So, once a device starts struggling with the current traffic loads or reaches its end-of-life status, firmware alone will not solve the problem.
