Quick answer: The Best Firewall Service Provider in 2025 is Perimeter 81!
Firewalls are very important for protecting your system against various threats – be it offline or online.
While firewalls are crucial for every system, they can easily become obsolete if hackers learn new tricks to bypass them. That’s why implementing your own firewall is very complex without previous experience.
However, as we speak, a very popular option is getting a firewall as a service, often referred to as FWaaS. Here, you won’t implement the firewall directly but you’ll rather pay for it in the form of a subscription.
This way, you don’t have to worry about maintenance, which is often the hardest part.
With dozens of FWaas providers on the market, it’s increasingly hard to choose the quality one.
Thus, our mission today is to give you the best firewall service providers that are proven and tested by our team. Without further ado, let’s delve deeper into this very important subject.

With the list of the best firewall service providers in 2025 out of the way, let’s talk about what exactly is a firewall.
People know that the word firewall usually means protection against some form of online threats. It is often used in the IT sector and this tool is a staple of online security for complex systems. If you think better, even Windows has a firewall built-in, which guarantees almost 100% protection against threats.
While Windows computers often utilize antivirus and anti-malware software, firewalls are somewhat different. Thinks of a firewall like security at the front of the entrance of a particular building. Their task is to filter out the potential threats and eliminate them if they start creating problems.
In the same fashion, firewalls reside at the very entrance of the company’s network, serving as the first (and usually the last) line of defense. They are here to eliminate viruses, malware, and other types of online threats so that they don’t endanger the company’s network.
Firewalls are also customizable and they can come as both hardware and software. The solutions we talked about are in the software form and they support various customization options. This means that they can react only to certain threats and even employ machine learning for added functionality.
Firewall technology changed a lot over the years and today, we have more advanced but also more reliable systems.
2.1 And How Does a Firewall Work?
The way the firewall is going to work mainly depends on the type of firewall we’re talking about. Luckily, we’re going to talk about some of the most popular ones in a few minutes but generally speaking, firewalls have the task of protecting your network or group of networks.
Once you put the firewall in place, it scans inbound traffic for potential threats. This is done via the firewall’s malware/virus database, which, during the traffic scan, is used to see if any familiar threats are found. Of course, this is just a basic explanation, as there are more advanced systems involved.
For example, some firewalls can use machine learning to adapt to new threats, which are then put into the database for further notice. Also, firewalls can detect if the inbound traffic is coming from an IP address that is a mismatch with that traffic’s originating location.
That’s why firewalls are so widely used – because they offer complete protection for systems with frequent updates, making them more reliable than any other solution.
3. Should I Use Cloud-Based Firewalls?
Cloud-based firewalls are the topic of today’s discussion. For those who didn’t read carefully, Firewall-as-a-Service or FWaaS is exactly the cloud-based firewall solution.
The point of this type of firewall is to eliminate the need for physically running the firewall in your company’s data center. Instead, the required protection is distributed online, which eliminates the load on the company’s resources, thus avoiding slowdowns in resource-demanding tasks.
For those wondering, cloud-based firewalls have no specific downsides except for a smaller degree of customizability. After all, these solutions come with pre-made plans available for purchase. On the brighter side, they offer all the security you need at a relatively affordable price.
Furthermore, FWaaS providers often include additional tools to bolster your protection. Some of them include a Virtual Private Network and antivirus, which makes your connection anonymous. As for the downtime, usually, it’s non-existent.
On rare occasions, providers will schedule the downtime in advance, which is sometimes necessary to apply the updates. But, as said, downtimes are very rare and the protection level is very high, making this type of firewall extremely reliable.
Should you use cloud-based firewalls then? Well, it depends on your needs. These solutions are often great for larger companies with several sites that need protection. However, they can be utilized by small businesses too especially if we talk about affordable solutions like Zscaler Cloud Firewall, for example.
4. What Is a Next-Generation Firewall (NGFW)?
Next-Generation firewalls or NGFW raise the level of protection significantly. Unlike traditional firewalls, they include deep packet inspection, which helps inspect the content of each inbound data packet. Besides, thanks to their advanced technology, they can even automatically detect malicious apps.
NGFW solutions allow you to use them on the app level. Thus, in your system, you can select how your employees will use the apps and which apps they can use. You can then forbid VoIP calls but allow them to share files, or perhaps, prohibit the use of P2P apps like Vuze or uTorrent.
One of the most important features of NGFW is machine learning. They follow the behavior of each inbound data packet to determine if it’s malicious or benign. Additionally, they can even decrypt encrypted packets and read their content, which makes NGFW much more secure.
Are NGFW solutions more secure than cloud-based ones? Sure!
On the other side, they’re very expensive, making them not suitable for users on a budget or small companies. Still, it’s vital to mention that they’re compliant with pretty much every standard and offer far more features than any other firewall type.
Therefore, if you need maximum protection and you don’t care about blazing-fast performance, which isn’t the focus here, NGFW providers are your best choice.
5. Popular Types of Firewalls Explained
Before concluding this discussion, we shall explain a few popular types of firewalls and see how efficient they are.
5.1 Traditional Firewalls
Traditional firewalls are the cheapest option, yet, in 2025, they’re not as great as they were before. Simply put, they’ll efficiently prevent malicious traffic from entering your network as long they’re correctly set up.
You can set them up to deny or allow traffic coming from particular IPs and ports, with no ability to protect the network from web-based attacks. The worst thing, however, is that an incorrect setup will most likely lead to a breach, which you want to avoid at all costs.
All in all, while not the most reliable option, it’s relatively easy to get it up and running and it won’t cost you a fortune to implement. However, make sure you set it up correctly to avoid potential problems and hacker attacks.
5.2 Container Firewalls
As its name implies, a container firewall has the ability to isolate application stakes, services, and workloads in a container. Once it does so, the firewall applies the settings you put in place to these containerized apps similar to traditional firewalls.
Needless to say, container firewalls can also protect the traffic outside the container, albeit, they don’t provide the highest possible level of security. That is because we’re talking about a newer type of firewall that didn’t have the time to mature and become as reliable as NGFW.
The good thing is that it’s easy to set up and configure, especially if you need extra protection for certain applications.
5.3 Database Firewalls
We should also talk about database firewalls. Logically, they protect databases from online-based attacks, and as such, they reside right in front of the database or group of databases. Their protection level is very high, as they can efficiently detect and eliminate database-aimed threats.
This is extremely valuable with companies that have confidential information not meant for sharing. Usually, companies use it to protect information regarding prototypes and yet-to-come projects that people outside the company shouldn’t know about.
What’s more, hackers often target databases because, many times, this information can be sold to the highest bidder for revenue. That’s where a database firewall comes in and does its job. Just be careful to update it frequently and have in mind that they offer almost no protection against zero-day threats.
6. Conclusion
With everything said, I think you now have a clear picture of what the best firewall provider is. While Perimeter 81 is the most popular option, you might want to take a look at the other choices depending on your needs.
All of these providers offer pretty much the maximum level of protection, and while some of them are more expensive, you can be sure that their security is rock-solid. Now, you can go ahead, test some of them via a free trial, and make a rational decision.
