The firewall rarely fails because it is bad. It fails because no one has looked at it since the day it was installed.
The firewall is the door between your network and the internet: it decides what gets in and what stays out. But it is also the easiest device to forget. Bought once, configured once, then set aside, with firmware from years ago, rules no one remembers the reason for, and a VPN that was never tested. The device built to protect becomes, itself, the open door, at the most critical point in the company.
Gartner estimated that the overwhelming majority of firewall breaches, around 99%, come from misconfiguration, not from a flaw in the device: the problem is almost never the firewall, it is the lack of someone to operate it.
According to the Verizon DBIR 2025 report, the exploitation of edge devices and VPNs as an entry point for attacks grew about eightfold in one year: the firewall itself has become one of the favorite targets.
And, in the same report, only about half of those edge and VPN flaws were fully fixed within the year: most firewalls keep running with the unlocked door the maker has already told them to close.
Managed firewall operation is exactly what is missing: someone who keeps the perimeter updated, the rules clean, the network segmented and the VPN working, every day. Zamak Technologies operates the front door; you run the business.
Why the front door is left open
The firewall that protects the company is, almost always, the one no one looks after.
See how the device built to guard the company becomes, over time, its most fragile point.
Installed once, never touched again.
The firewall was bought and configured once, and since then no one has looked at it. The firmware is several versions behind, with flaws the maker fixed long ago. It is still on, the green light gives a false sense of safety, but inside it is an old door with a lock everyone already knows how to open.
Years of rules no one remembers the reason for.
Over time, someone opened a port for the printer, another for a supplier, another to solve a problem in a hurry. Each rule stayed, and no one ever cleaned them up. Today it is a tangle in which one of those doors is still open to the entire internet, and no one knows which, because no one documented anything.
The maker said to patch it. Months later, nothing done.
The firewall has become a favorite target: the maker releases a critical fix for a flaw in the device itself, but applying it takes care and no one owns that task, so it is left for later. The door that should be locked stays wide open, now with the map published for any attacker.
The remote workers' VPN: either it went down, or it is too wide open.
The firewall is also the remote-access gateway for the team working from outside. Misconfigured, it does the worst of both worlds: either it locks the whole team out on a workday, or it leaves a door too wide open to the internet, through which an attacker walks in as if they were an employee. And almost no one tests it to find out which of the two states it is in.
Everything on the same network: get into one, reach everything.
With no segmentation, the whole network is a single room: the intern's machine, the file server and the finance system, all in the same space. One infected computer is enough for the attack to walk free all the way to where it hurts. The firewall could split the network into zones and contain the damage, but with no one to design and maintain those zones, it splits nothing.
None of these problems is the device's. They all come from the same thing: the firewall has no owner. It is that daily care of the perimeter, the door always locked and up to date, that managed operation puts in place.
What managed firewall operation is
It is not buying a firewall. It is having someone care for the door, every day.
The firewall is the device that sits between your network and the internet and decides what gets through. Managed operation puts Zamak in charge of that perimeter: keeping the firmware updated and the device up, reviewing and cleaning the rules so no door is left open for no reason, segmenting the network into zones that contain an attack, keeping the remote-access VPN working securely, and delivering a report of what the perimeter is doing. You are not just buying a box: you get someone who cares for the front door.
The perimeter updated and up
The firewall's firmware is kept current, with the maker's fixes applied carefully, and the device's security features stay on and updated. Availability is monitored, because a perimeter that goes down leaves the company exposed or stopped. The door stays always locked and up to date.
Clean rules and a segmented network
The firewall's rules are reviewed, documented and cleaned: no door left open for no reason and no rule forgotten from years ago. And the network is split into zones, so an infected computer cannot reach the finance system or the file server. Every access now has a reason to exist.
Secure VPN and reporting
The remote-access VPN is kept configured and working, so the outside team gets in securely, without leaving a door too wide open. And a monthly report shows, in business language, the state of the perimeter, what changed and what the firewall blocked.
The firewall is one layer of defense, and operating it well closes the front door, but it is not, on its own, a guarantee of security. Detecting and responding to what gets through the door is managed cybersecurity, and filtering browsing is web protection, both their own layers that Zamak also offers. Operating the firewall is caring for the door; it is not pretending nothing else is needed.

Inside the service
How managed operation cares for the perimeter
For those who want the detail: this is how the perimeter stays locked, up to date and under control.
Firmware and availability
The firewall's firmware fixes are assessed and applied in a planned window, because the firewall itself has become an attack target and running outdated is an open door. The perimeter's availability is monitored around the clock, and the device's security features stay on and updated.
Rules and policies
The rule base is reviewed, documented and cleaned: orphan rules are removed, every access gets a recorded reason, and the principle is least privilege, only what is needed gets through. Every rule change is treated as change management: tested, documented and reversible, so as not to open a hole or lock out someone who needs access.
Network segmentation
The network is split into zones by the firewall, separating what needs to be separate: the finance system on one side, the user workstations on another, guests in an isolated zone. That way, a compromised computer stays contained in its zone, instead of reaching the whole company.
Remote access (VPN)
The firewall is usually also the remote team's VPN gateway. The operation keeps that access configured, tested and working, with proper authentication, so that those working from outside get in securely and the door is neither locked for those who need it nor too open for those who should not.
Reporting and evidence
Every month you get a report of the perimeter: the firmware applied, the rule changes, the state of the VPN and what the firewall blocked. It is the proof of care in business language, and serves as evidence for audit and insurance, which increasingly require the perimeter to be managed and up to date.
Coverage and honest scope
The operation cares for the firewall your company already has, or helps choose and deploy a suitable one. In scope is the proactive care of the perimeter: firmware, rules, segmentation, VPN, availability and reporting. Detecting and responding to what gets through the door is managed cybersecurity, and filtering browsing is web protection, their own layers. That keeps the promise honest: care for the front door, not promise it alone protects everything.
The operation is run through a remote management platform that runs on infrastructure certified to SOC 2 and ISO 27001, compliant with HIPAA and PCI-DSS, and management access to the firewall travels encrypted.
The platform monitors the perimeter's availability and automation acts around the clock, every day; Zamak's specialists operate, tune, patch and are your point of contact during business hours.

The comparison
Managed operation, install and forget, or the internal team on its own
There are three ways to care for the firewall: install once and forget (and only call someone once there is already a problem), leave it to an internal team that has neither the time nor the routine for the perimeter, or a managed operation that keeps the firmware, the rules, the segmentation and the VPN under control, every day. These are operating models, not a comparison against a specific vendor. The Zamak column lists only what Zamak delivers to the client.

For every decision maker
What this means for whoever decides
Caring for the perimeter solves a different pain for each role in the company.
Owner and founder
The front door of the business stays guarded
The firewall is the border between everything you built and the outside world. Leaving it without an owner is trusting the front door to a device no one has looked at in years. Here it is cared for every day, and the nasty surprise from the most critical point stops being a matter of time.
Executives and management
A predictable cost and proof the perimeter is up to date
Instead of finding out the firewall's state only on the day of the incident, you have a predictable monthly cost and a report that proves a managed perimeter, increasingly required by audit and cyber insurance. The risk that came from the forgotten door becomes a controlled line on the spreadsheet.
Internal IT leader
The most specialist device operated by people who do this every day
The firewall is the device that punishes a misconfiguration the most and forgives a lack of time the least. Taking the perimeter operation off your list, to people who work on this every day, frees you from the risks of a badly made change and from the work that is always left for later. Zamak's support adds to your work, it does not replace it.
