Let’s be honest, firewalls aren’t exactly exciting until something goes wrong. A misconfigured rule, an overlooked update, or a patch that never got applied can turn into a serious problem fast. That’s why companies across Europe don’t leave this to chance. They turn to specialists who spend their days making sure networks stay locked down without breaking business workflows.
In this article, we’ll look at some of the top companies in Europe that focus on firewall configuration and network security. These are the teams that help businesses avoid costly downtime, keep compliance in check, and sleep a little better at night knowing their systems aren’t wide open to the internet.
1. A-Listware
At A-Listware, we position ourselves as a partner for European clients who need help with software development and IT support. Most of our projects come from companies across Europe, which means we’re used to working in different business cultures and adapting to varied technical setups. Security always finds its way into those projects, and firewall configuration is part of the groundwork we handle when we’re building or maintaining systems.
We don’t see firewalls as a standalone service but as one layer in a much bigger picture. When we’re developing applications, setting up infrastructure, or supporting long-term operations, we make sure security is built in from the start. That often involves configuring firewalls, keeping them aligned with compliance needs, and making sure clients don’t have to worry about gaps that could leave their systems exposed. It’s practical, ongoing work that runs in the background while our clients stay focused on their business.

2. Zen Internet
Zen Internet is a long-running UK-based provider that started out in broadband but has gradually moved into a wider set of business services. These days, their focus isn’t just on keeping companies online but also on keeping their networks secure and reliable. Firewall setup and ongoing management are part of that mix, making sure businesses don’t leave gaps in their infrastructure.
They approach security as part of a bigger picture. Instead of just dropping in hardware or software and leaving it at that, they tend to work with clients to match the firewall configuration to how the business actually operates. It’s not the most glamorous work, but it’s the kind that prevents late-night calls when something fails or when a vulnerability slips through unnoticed.

3. ANS
ANS is a UK-based technology company that has shifted over the years from straightforward IT support into a mix of cloud, security, and managed services. Firewalls sit right in the middle of that stack, since keeping business systems online doesn’t mean much if the network is full of holes. Their role often involves not just installing firewall tech but also making sure it keeps pace with how businesses actually work day to day.
They tend to frame security as part of a bigger ecosystem rather than a bolt-on. So alongside firewalls, they look at cloud setup, infrastructure, and compliance as connected pieces. That means their work usually touches more than one area at once, making them less about one-off fixes and more about ongoing management. It’s practical work, and while it might not make headlines, it’s the kind that helps companies avoid the usual “something’s broken, now scramble” scenario.

4. Maintel
Maintel is a UK company that grew out of the world of business communications but now handles quite a bit more than phones and networks. Alongside managed connectivity and cloud projects, they also spend time on security work, which naturally includes firewall configuration. Their angle tends to be about keeping the infrastructure that companies already rely on secure without adding too much complexity on top.
They often end up working with businesses that are juggling multiple systems across voice, data, and cloud setups. In that context, firewalls are just one piece of the puzzle, but an important one. Their approach is usually about tying things together in a way that doesn’t disrupt everyday operations while still making sure the basics of protection are covered. It’s steady, behind-the-scenes work that helps keep larger systems running smoothly.

5. Colt
Colt is known more for their network backbone across Europe than anything else, but that scale naturally pulls them into security work too. If you’re moving a lot of traffic for businesses, you need to make sure it’s not only fast but also protected. That’s where their firewall services come in, sitting alongside the bigger connectivity setup they manage for clients.
They usually approach things from an infrastructure angle. Firewalls aren’t treated as a standalone product but as part of the wider network environment they’re already running. This makes sense given their background in telecom and data services. Their work is less about fancy extras and more about making sure businesses can rely on secure connections day in, day out without constant tinkering.
נקודות עיקריות:

- Offers firewalls as part of wider connectivity and infrastructure services

6. GTT
GTT is mainly thought of as a global network provider, moving data around for businesses that operate across borders. Alongside all that infrastructure, they also handle security, and firewalls are naturally part of that picture. If you’re carrying traffic on a large scale, it makes sense to build protection directly into the network rather than bolt it on afterward.
Their approach tends to focus on consistency. They’re dealing with clients who often run offices in multiple countries, so firewalls have to be managed in a way that doesn’t break when teams are spread across different regions. Instead of one-off fixes, they usually provide firewall configuration as part of an ongoing service, making sure businesses can keep working without worrying too much about the technical details behind it.
נקודות עיקריות:

7. Bechtle
Bechtle is one of those companies that cover a lot of ground in IT, from hardware procurement to managed services. Security fits into that mix, and firewalls are a natural part of the setup they provide. Rather than treating firewall work as a separate task, they fold it into broader projects like network design, cloud migrations, or general infrastructure upgrades.
Because they deal with so many different clients, their role is often about balancing standard security practices with the quirks of each business environment. That could mean configuring firewalls to slot neatly into existing systems or managing them as part of a long-term support contract. It’s not flashy, but it’s the sort of groundwork that keeps larger IT projects stable.
נקודות עיקריות:
- European IT services provider with a wide portfolio
- Handles firewall configuration within broader infrastructure work
- Works across industries with varied business setups
- Provides both short-term projects and long-term management

8. Orange Cyberdefense
Orange Cyberdefense is the security-focused arm of Orange Group, so their whole job revolves around protecting digital systems. Firewalls are one of the building blocks they handle, usually set up as part of larger security frameworks. Instead of dropping in a single tool and walking away, they tend to manage things over the long haul, making sure the protection keeps pace with whatever changes a business is going through.
They work with organizations that already have plenty of moving parts in their IT setups, so their firewall work often sits alongside monitoring, threat detection, and compliance. The idea is to reduce the number of blind spots while keeping the systems usable for the people who actually run the business day to day. It’s more about steady, behind-the-scenes work than anything flashy.
נקודות עיקריות:
- Security division of the Orange Group
- Focused on long-term protection rather than one-off fixes

9. Softcat
Softcat is a UK-based company that’s known for covering just about every corner of IT services. They don’t really stick to one lane, so their work can be anything from supplying hardware to managing complex security setups. Firewalls naturally sit inside that mix, often showing up as part of bigger projects where companies are trying to tighten their security without rebuilding everything from scratch.
Because they deal with such a wide range of clients, their firewall work isn’t one-size-fits-all. Sometimes it’s about helping a business set up new protections from the ground up, and other times it’s about keeping existing systems patched, monitored, and running without drama. Their style is usually practical rather than flashy, with a focus on making sure businesses can keep operating without security becoming a constant headache.

10. Cancom
Cancom is a German IT services provider that mixes infrastructure projects with managed services. Their work usually stretches across cloud, networking, and security, and firewalls end up being a basic but important part of that setup. Rather than treating firewall work as a side job, they fold it into the bigger systems they design or maintain for clients.
They often deal with businesses that have a mix of on-site systems and cloud environments, which means firewall configuration has to cover both worlds. In practice, that can involve building out new protections for hybrid networks or managing existing firewalls as part of long-term service contracts. The goal is generally to keep systems secure without creating too much complexity for the people running them.

11. Swisscom
Swisscom is best known as Switzerland’s main telecom provider, but they’ve moved far beyond phone lines and internet connections. These days, their work covers cloud services, IT infrastructure, and managed security. Firewalls are one of the basics they handle, usually as part of bigger projects that involve keeping networks both fast and safe.
They often work with companies that don’t just need connectivity but also want reassurance that their systems are properly protected. Their firewall configuration is usually tied into monitoring, compliance, and broader IT management. It’s less about one-off installs and more about making sure businesses stay secure over time while still being able to get on with their day-to-day operations.

12. OVHcloud
OVHcloud is mostly known as a big European hosting provider, but their work stretches beyond servers and storage. Because they run data centers and cloud platforms at scale, security ends up being part of almost everything they do. Firewalls are one of the basic tools they provide, often bundled into larger hosting or cloud solutions.
Their firewall setup usually ties into the services clients are already using. That could mean protecting hosted applications, segmenting traffic in a private cloud, or giving customers managed firewall options so they don’t have to worry about tuning everything themselves. It’s not really treated as an add-on but more like a standard part of how they keep systems up and running securely.

13. A1
A1 is mainly known as a telecom operator in Austria, but over time they’ve moved deeper into IT and security services. Their role now isn’t just about keeping people connected but also about making sure those connections are safe. Firewalls are a core part of what they set up for businesses, often bundled with other services like managed networks or cloud hosting.
They usually work with companies that want a mix of connectivity and protection without having to deal with too many different providers. In practice, that means configuring firewalls, monitoring them, and keeping everything updated as part of a bigger managed service. It’s the sort of steady background work that keeps systems running without becoming a distraction.

14. Claranet
Claranet started out as an internet service provider but over the years they’ve shifted into a broader role, covering cloud, networking, and security. Firewalls are a natural part of that lineup, usually managed alongside other services rather than treated as a separate add-on. Their work tends to focus on keeping things simple for businesses that don’t want to juggle multiple providers just to stay connected and secure.
They often end up working with companies that have a mix of on-premise systems and cloud environments. In those cases, firewalls play a key role in bridging the two and making sure everything stays protected without slowing down day-to-day operations. Their style is more about ongoing management and steady reliability than one-off fixes.

מַסְקָנָה
When it comes to firewall configuration in Europe, there’s no shortage of companies that can step in and handle the nuts and bolts. Some keep it simple and tie security directly into connectivity, while others fold it into broader IT or cloud projects. The point isn’t really about who’s the biggest or flashiest, it’s about finding a partner that fits the way your business actually works.
If you’re weighing your options, it makes sense to start small, maybe with a managed service or a specific project, and see how the collaboration feels. Firewalls aren’t the most glamorous part of IT, but they’re one of those things that quietly keep everything else running. Get that piece right, and the rest of your setup has a much better chance of staying solid.
