Why Complete IT Visibility Is Harder Than It Sounds

Complete IT visibility is difficult because modern IT environments constantly change, and no single tool can track every endpoint, cloud resource, SaaS application, identity, and internet-facing asset. Organizations instead build visibility by combining information from multiple systems and continuously updating their understanding of the environment.

For many IT teams, visibility starts with discovering devices. In reality, that is only one part of the challenge. Hardware, software, cloud services, identities, remote devices, and external exposures all contribute to an organization's security and operational posture. If even one of these areas is incomplete, IT teams can struggle to patch systems, investigate incidents, manage compliance, or make informed operational decisions.

The NIST Cybersecurity Framework (CSF) 2.0 reflects this broader perspective by defining asset management as more than maintaining a hardware inventory. Organizations are expected to understand hardware, software, services, data, facilities, suppliers, and people according to their importance and associated risk.

IT visibility is more than discovering devices

When people think about IT visibility, they often picture a list of computers connected to the network. While asset discovery is essential, it represents only one layer of visibility.

According to NIST SP 1800-5: IT Asset Management, effective IT asset management combines information from multiple operational and security systems to understand not only which assets exist, but also their software, vulnerabilities, ownership, and operational status.

Likewise, CIS Control 1: Inventory and Control of Enterprise Assets defines enterprise assets broadly to include servers, workstations, mobile devices, network infrastructure, cloud resources, virtual machines, remote devices, and IoT equipment. It also emphasizes identifying unauthorized and unmanaged assets alongside approved ones.

As environments grow, complete IT visibility depends on correlating information from endpoint management platforms, cloud providers, vulnerability scanners, identity systems, and configuration databases rather than relying on a single inventory.

Modern IT environments are constantly changing

Even a well-maintained IT asset inventory can become outdated quickly.

Organizations deploy new cloud workloads, onboard remote employees, retire devices, install software, and adopt new services on a continual basis. Virtual machines and containers can be created and removed dynamically, while cloud resources may automatically scale based on operational demand.

The CISA Cross-Sector Cybersecurity Performance Goals Version 2.0 recommend maintaining current inventories while integrating asset management with vulnerability management, identity security, cloud security, logging, and exposure management. Rather than treating visibility as a one-time project, the guidance presents it as an ongoing operational capability.

This challenge becomes even greater in organizations where different business units manage their own infrastructure or adopt cloud services independently.

Shadow IT creates visibility gaps

Not every application enters an organization through centralized IT.

Employees and business units may adopt SaaS applications, collaboration tools, browser extensions, automation platforms, or cloud storage services without formal IT approval. These technologies can improve productivity while also creating assets that never appear in traditional inventories.

The Cloud Security Alliance's State of SaaS Security Report 2025 found that surveyed organizations continue to face challenges related to fragmented SaaS administration, unauthorized SaaS adoption, excessive permissions, and sensitive information being uploaded to unapproved applications. These findings illustrate how visibility gaps can emerge even when endpoint inventories are accurate.

To help organizations improve SaaS visibility, CISA developed the Secure Cloud Business Applications (SCuBA) Project, which provides guidance for strengthening visibility and security across cloud business applications and hybrid identity environments.

Software inventory is just as important as hardware inventory

Knowing that a device exists does not reveal everything running on it.

Applications, services, browser extensions, scripts, and unauthorized software can all introduce operational or security risks without changing the hardware inventory itself.

CIS Control 2: Inventory and Control of Software Assets treats software inventory as a separate security objective because organizations must identify both authorized and unauthorized software across the enterprise.

Meanwhile, NIST SP 1800-5 explains that physical asset inventories alone cannot provide information about installed operating systems, applications, or vulnerabilities. Combining these sources creates a much more complete picture of the environment.

The accompanying Guide to Enterprise Assets and Software also highlights the importance of maintaining consistent records for ownership, authorization status, identifiers, and asset context so different teams are working from the same information.

Cloud computing changes what organizations can see

Traditional data centers generally provided organizations with direct visibility into most of their infrastructure.

Cloud computing changes that model.

In NISTIR 8006: NIST Cloud Computing Forensic Science Challenges, NIST explains that customers have different levels of visibility depending on the cloud service model. Infrastructure-as-a-Service customers typically have more operational visibility than Software-as-a-Service customers because cloud providers manage much of the underlying infrastructure.

Similarly, the ENISA Cloud Cybersecurity Market Analysis discusses how shared responsibility and varying levels of transparency between cloud providers and customers influence cloud security operations.

As organizations continue moving workloads to the cloud, IT visibility increasingly depends on integrating cloud APIs, identity systems, and cloud-native management tools alongside traditional infrastructure management.

Internal inventories do not always match external exposure

An organization's internal records may not fully reflect what is accessible from the internet.

Misconfigurations, forgotten cloud deployments, remote access services, development environments, and other internet-facing systems can create unexpected exposure outside normal operational visibility.

CISA's Internet Exposure Reduction Guidance recommends evaluating internet-facing assets from an external perspective because publicly exposed services may differ from internal inventories.

This external perspective helps organizations identify publicly accessible systems that internal asset inventories may miss.

Identity has become part of IT visibility

Modern IT visibility extends beyond devices and software.

Organizations also need to understand who is accessing resources, which devices they are using, whether those devices meet security requirements, and what resources they are attempting to access.

NIST SP 800-207: Zero Trust Architecture describes security decisions based on continuous evaluation of users, devices, resources, authentication, authorization, and contextual information rather than assuming trust based solely on network location.

As hybrid work and cloud adoption continue to grow, identity data becomes an increasingly important part of maintaining complete IT visibility.

Why no single tool provides complete IT visibility

Most organizations collect operational information from numerous platforms, including endpoint management systems, network discovery tools, vulnerability scanners, identity providers, cloud platforms, SaaS administration tools, configuration databases, and security monitoring solutions.

Each platform answers different operational questions and often maintains its own identifiers, update schedules, and data formats.

NIST SP 1800-5 demonstrates that effective IT asset management depends on integrating information from multiple systems rather than relying on one source of data. Likewise, the MITRE Center for Threat-Informed Defense's Sensor Mappings to ATT&CK shows that different security sensors observe different types of activity, reinforcing that no single source provides complete operational visibility.

Building complete IT visibility therefore requires correlating information across multiple management and security systems.

Building continuous IT visibility

Maintaining complete IT visibility is an ongoing challenge because IT environments continuously evolve. New devices appear, software changes, cloud resources scale, identities change, and internet-facing services are introduced or retired over time.

Rather than treating visibility as a one-time inventory exercise, successful organizations build continuous processes for asset discovery, software inventory, identity management, cloud monitoring, vulnerability management, and exposure management.

For IT teams using platforms like Level, endpoint visibility provides an important foundation, but it becomes significantly more valuable when combined with information from cloud platforms, identity providers, vulnerability management systems, and other operational tools. Bringing these sources together helps create a more accurate understanding of the IT environment and supports better operational decision-making.

The guidance from NIST CSF 2.0, NIST SP 1800-5, and the CISA Cross-Sector Cybersecurity Performance Goals Version 2.0 points toward the same conclusion: effective IT visibility is not achieved through a single discovery tool. It is built through continuous asset management, software inventory, identity awareness, cloud visibility, and the integration of multiple trustworthy data sources.
