An abysmal 4% of organizations consider their internet-connected devices and associated technologies secure. Four. Percent.
It’s a figure that would justifiably send enterprise leaders’ minds into a tailspin, especially when you consider that most teams already have security tools in place that should give them more confidence.
In reality, the gap is upstream. Those tools only govern assets they know exist. They monitor what's online, active, and enrolled. They don't see devices in procurement, storage, or retirement. They don't see shadow IT. They don't see assets that changed hands without a record update.
Those gaps result in bad data, and it’s in those gaps that hackers are making their move.
While malware and phishing attacks are not slowing down, new attack methods are emerging–ones that don’t bother going through defenses, but rather around them. We call this “The Overlooked Perimeter”.
Modern IT asset management (ITAM) is essential for protecting your enterprise from these overlooked vulnerabilities.
In this blog, we explore:
- The hidden risks that result from poor IT data
- The financial and compliance-related costs of consistently unmanaged IT assets
- The tangible benefits of accessing accurate, real-time IT data via comprehensive ITAM
How Do Attackers Exploit The Assets Security Tools Can't See?
The Overlooked Perimeter is the attack surface that exists outside traditional security monitoring: assets in procurement, storage, retirement, or off-network lifecycle stages that EDR, SIEM, and endpoint tools don't see.
Most enterprise security strategies account for assets–physical and digital–that are online and deployed for current use. They don't take pre-deployed, offboarded, or transitional assets into account. This is where bad actors are striking.What makes pre-deployed assets vulnerable to attacks?
These assets often lack the security configurations and monitoring that come with full deployment, creating windows of opportunity for attackers.
These assets tend to fall outside the purview of traditional IT asset management solutions. Without accurate data of these lifecycle stages, IT opens the door for attacks long before and after they have the chance to fortify assets with their own security measures.
Bad actors are making every effort to bypass your security controls and gain access to your organization.
How do attackers exploit devices in storage or retirement?
The answer lies in targeting assets during their most vulnerable lifecycle phases.
For example, attack groups like UNC3944 have accessed network planning details to commit procurement fraud and install and later launch persistence on devices in storage. Black Basta can (and has) reactivated devices in retirement and leaked stolen data from improperly wiped devices intended for recycling.
The only way that your teams can protect against these attacks is if you have full visibility into the asset’s entire lifecycle and accurate data that informs each stage.
Unfortunately, on top of excluding offline, non-deployed, and unknown devices, most raditional tools are downstream of a data problem they can't solve. They can’t control hardware and software access, detect and report suspicious activity, or uncover vulnerable, untracked assets.
This is particularly concerning, given that survey respondents within the 2025 IDC Spotlight Paper cited shadow IT as a major challenge within their ITAM efforts.
It’s a vicious cycle. IT leaders can’t protect assets they don’t know about. Their current tools don’t deliver that asset data. So, until they find a solution to solve that conundrum, they’re left operating with a Trust Gap that attackers have already mapped. –ones that come with very real consequences.
What are the Costs of Ignoring Unmanaged Assets?
Far from one-off consequences, these impacts snowball into more complicated problems across IT and other functions.
The longer IT assets go ungoverned, the greater danger they pose to the organization, such as:
- Budget Overruns (Finance): As more employees purchase hardware and licenses outside of IT’s processes, spend skyrockets and budgets become unmanageable.
- Noncompliance (GRC/Legal): Shadow IT and unmanaged assets fail to meet compliance standards and result in costly fines.
- Data Breaches (Security/Finance): Security vulnerabilities can result in data breaches, which cost an average of $4.45M to resolve.
- Business Disruptions (Operations/Executive): Depending on the scale of the attack, it can take anywhere from a few hours to a few weeks to resume business as usual, all the while you lose money as a result of operational disruptions.
There's a reason that IT leaders so strongly warn against non-IT-approved devices and software and, especially in recent years, are taking such greater measures to expand visibility into every asset. They know the heavy toll attacks take on their efforts, credibility, and the business as a whole.
What Companies Have Experienced Data Breaches?
Cyberattack groups are well aware of the vulnerabilities exposed when unmanaged assets and shadow IT persist within enterprise organizations–and they have wasted no time taking advantage of those vulnerabilities.
Uber
Employees used unauthorized software that attackers leveraged to access and expose customer credit card data. The breach wasn't a failure of asset governance: software that existed outside the visibility framework entirely.
Target
Unapproved applications used by employees lacked proper security controls, giving attackers a path to the payment system. The entry point was one that their IT environment didn’t know about..
Okta
A single employee's personal email account, accessed on a company device, was compromised and used to breach Okta systems. One ungoverned device-identity relationship created cascading exposure across the organization.
If organizations are going to protect themselves from these attacks and their consequences, IT leaders need to leverage solutions that not only bring unmanaged assets to light but also continuously deliver accurate data so they can cover their entire IT landscape at every lifecycle stage.
How Does Full-Lifecycle ITAM Cover the Overlooked Perimeter?
The need for an ITAM platform to deliver continuous, full-lifecycle visibility cannot be understated.
Thankfully, as revealed in the IDC Spotlight Paper, IT leaders recognize that robust asset management practices, supported by accurate, trusted IT data, can help organizations identify previously unmanaged assets and the users associated with that asset to spot security risks and take the necessary steps to avert crises.
But that’s only possible with a solution that offers much more than traditional capabilities. It’s possible with Oomnitza.
Oomnitza Closes Lifecycle Visibility Gaps
Oomnitza captures complete lifecycle data and orchestrates integrations with procurement, security, HR, and IT operations systems to deliver audit-grade visibility and compliance-ready ITAM. Our platform is:
Full Asset Lifecycle Governance, Even Those Offline
We establish a persistent, object-based record for every IT asset from initial forecasting through final financial write-off.
You get firm records that support audit, regulatory compliance, and security investigations, as well as proactive identification of security gaps before they become attack vectors.
Enriched Asset Context That Improves Security Tools’ Accuracy
We act as a foundational context layer rather than a replacement for your existing tools.
You get total asset context for accurate threat correlation in SIEM tools. Enriched lifecycle intelligence means fewer false negatives in Cyber Asset Attack Surface Management (CAASM)-based risk reporting.
Automated Compliance and Disposal Workflow
Lifecycle-triggered automation in Security Orchestration, Automation, and Response (SOAR) platforms allows for compliance, isolation, or disposal workflows. With time-stamped, controlled decommissioning, and secure disposal and data sanitation, you never have to worry about manual compliance measures.
Frequently Asked Questions
1. How do attackers exploit assets that aren't in active IT inventory?
Pre-deployed devices often lack security configurations. Retired devices may hold unwiped data. Assets in storage can be tampered with during transit. Attack groups like UNC3944 and Black Basta have documented methods for accessing, persisting on, and exfiltrating data from assets in these ungoverned lifecycle stages.
2. Why aren't EDR and SIEM tools enough to close enterprise security gaps?
EDR and SIEM tools only monitor enrolled, online, active devices. They don't cover assets in procurement, staging, or retirement, and they depend on asset records they don't control. When those records are incomplete, security tools inherit the same blind spots.
3. How does full-lifecycle ITAM improve security posture?
Full-lifecycle ITAM extends governance to every asset stage, including procurement, storage, deployment, and decommission. By maintaining a continuous, accurate record of every asset and its security state, ITAM gives Security teams the context they need to govern the complete attack surface, not just the visible portion of it.
Oomnitza Makes the Overlooked Visible and Defensible
Closing the Overlooked Perimeter means closing the Trust Gap. It means building a governance foundation where every asset is tracked across its full lifecycle, every lifecycle event is logged and attributable, and the record security tools depend on reflects what actually exists, not just what's currently online.
With complete visibility across the entire asset lifecycle, Oomnitza empowers IT teams to transform their data from something simply used for inventory to a strategic advantage in an increasingly complex environment.
