Most breaches are not exotic. They start with an old machine, forgotten software or a misconfigured endpoint nobody owned. ITAM is the layer that finds them first.
You can’t secure what you can’t see.
The problem is that seeing everything you own keeps getting harder. More tools, more platforms, more frameworks, more vendors — added continuously, often faster than anyone documents them.
And those are just the ones you know about. In a 2025 study of UK IT leaders, 64% of organisations had discovered previously unknown devices or applications being used for work in the previous year, and 67% said they lacked complete visibility of all work devices.
That is why IT Asset Management is such a large part of cyber defence. It gives security teams a trusted, current view of what exists, what is at risk and what needs fixing first.
Security teams want fewer unknowns, because unknowns are where the risk lives.
In that same study, 48.4% of UK companies had suffered a data breach caused by unmanaged or unseen devices in the previous year.
Any gap in visibility means you cannot know whether governance and security protections are actually in place. What you get instead is an unguarded attack surface that only the attacker has mapped.
ITAM knows what is out there. But without a single source of truth, the data stays fragmented — and fragmented data is how machines get missed, devices go unpatched and servers stay online with no owner and no support plan.
Imagine an organisation with more than 5,000 devices. If just 1% are invisible, that is 50 additional opportunities for someone to find a way in.
This is the specific problem CerteroX ITAM is built around. Ten discovery methods — agent, command line, agentless, standalone, Active Directory, network scan, third-party import, cloud connector, browser monitoring and file metering — all land in one schema. There is no reconciliation project, because there is nothing to reconcile. Native agents cover Windows, macOS, Linux, AIX, HP-UX and Solaris, so the platforms most tools quietly exclude are inside the same inventory as everything else.
Most breaches are not zero-day exploits.
They happen because of old machines, forgotten or unmanaged software and misconfigured endpoints. Every one of those is something an asset platform can expose.
Effective ITAM shows what is running, where it is, who is responsible for it and whether it is current. Warranty retrieval and expiry tracking tell you which hardware is already past the point where anyone will help you fix it. Duplicate system detection and stale device archiving keep the record honest instead of letting it inflate.
That is what security teams need in order to act quickly.
Think back to the Log4Shell incident in 2021 — a critical vulnerability in Log4j, a logging component used by an enormous number of online services, including those run by governments and major organisations.
When the vulnerability was identified, the UK’s National Cyber Security Centre advised:
The best thing you can do to protect yourself is make sure your devices and apps are as up to date as possible and continue to update them regularly, particularly over the next few weeks.
The only way to do that properly is to have full visibility of every device. With a visibility gap, there was always a risk you would miss one — and a missed one is a breach waiting to happen.
Security and governance rules no longer just require you to block threats. You also have to prove you were in control when something goes wrong.
GDPR, for example, requires audit trails of the steps taken and actions completed to prevent attacks. Gaps in that record put you below the compliance standard. For lower-tier breaches, UK GDPR fines reach up to £8.7m or 2% of global annual turnover, whichever is higher. For higher-tier breaches, up to £17.5m or 4%.
ITAM gives you accurate, accessible asset data that lets you act fast during an incident and document what was done afterwards without gaps. Role-based access control, reporting levels and a full audit trail across agreements, transactions and exclusions mean the evidence is a query rather than an archaeology project.
The answer to better security and compliance is not always more software. Security stacks are crowded enough already.
What you usually need is better integration between the tools you have. When asset data reaches your CMDB, your SIEM dashboards and your vulnerability management platform, everyone works from the same picture of what is live, what is exposed and what needs attention now.
CerteroX exposes a read-only API with a documented Power BI data source, so the inventory can feed those systems directly rather than through an export someone maintains by hand.
Picture a global retailer with its asset inventory wired into the relevant tools. The security team can cross-reference patch levels, ownership and warranty status against threat data on one screen. When a zero-day alert arrives, they already have a verified list of affected machines.
Which makes it a genuine worry that in a February 2020 survey, 43% of IT professionals reported still tracking IT assets in spreadsheets.
You can buy all the security software you want. If you do not have visibility of what needs protecting, you will always have gaps.
Most leading security tools have decent discovery and can interrogate a network well. But none of them is perfect, so a safety net that catches the anomalies is essential.
When something happens, you want to know immediately what is affected and how to fix it — not go digging through old files and spreadsheets.
ITAM may not sit under the security banner on the org chart. It is still one of the most useful things a security team can be given.
Improving your security starts with improving visibility.

Windows 10 support ended in October 2025. If you are still finishing the migration — or paying for Extended Security Updates while you do — these are the questions to settle and a readiness check to score yourself against.
Mobile device management works properly when phones and tablets sit in the same inventory as everything else you own. Here is what CerteroX ITAM does with enrolled iOS and Android devices, and why the single record matters.
When Microsoft patched a wormable Remote Desktop flaw serious enough to warrant emergency updates for Windows XP, the hard part was not the patch. It was working out which machines you owned that needed it. That is a hardware asset management problem, and it has not gone away.
