As organizations grow, their IT assets grow exponentially. According to Technavio, the global IT asset management software market size is estimated to grow by $456.14 million between 2024 and 2028, growing at a CAGR of nearly 7.58% during the forecast period.

Effective infrastructure management starts with a thorough inspection of your organization’s environment. To effectively identify and record assets across hardware devices, software applications, network components, and more, IT professionals can leverage asset discovery tools.

With accurate asset inventory management, organizations can strengthen their security posture, optimize and allocate resources, streamline processes, and meet compliance.

An asset discovery tool is a software solution that automatically identifies, classifies, catalogs, and monitors all assets within an organization’s IT infrastructure. Asset discovery tools can identify known resources as well as uncover redundant, unmanaged, or unauthorized assets and devices.

There are two different types of IT asset discovery tools: active and passive.

The difference between an active vs passive asset discovery tool is that an active one proactively sends requests to assets and collects responses to manage the assets. Passive discovery monitors network traffic without directly interacting with the devices.

An organization’s infrastructure is composed of many different assets. Ten of the most common types of IT assets managed with discovery software include:

These assets are critical components of modern infrastructure, and they can be easily discovered and monitored through asset management. Organizations can also reveal known, unknown, vendor, and rogue assets. After all, you can’t manage what you can’t see.

As organizations grow and evolve, assets are constantly being added, removed, or modifiedmaking it difficult to maintain an accurate inventory. The addition of shadow IT, where unauthorized devices and software are used without the knowledge of IT departments, further obscures asset visibility.

With continuous asset discovery, organizations can detect shadow clouds, network infrastructure, and unknown endpoints.

The main benefits of asset discovery include:

• Improved Security: Reduces risk with continuous, accurate detection of assets


• Operational Efficiency: Accelerates business while reducing time and resource needs


• Cost Reduction: Eliminates redundant assets that can be modified or reduced


• Compliance Assurance: Streamlines inventory for accurate compliance reporting


• Enhanced Decision-Making: Helps determine network upgrades, cloud migration, and address business changes quickly

IT asset discovery works by identifying and cataloging devices in a network, including endpoints, routers, switches, and OT/IoT devices. They can be used in both cloud and on-premises environments.

Through the asset discovery process, organizations can find specific information, including usage patterns, software installs, and configuration details. This data is consolidated into a centralized inventory, providing IT and security teams with an up-to-date, unified view of their asset data. This single source of truth helps manage, track, and secure IT resources effectively.

IT asset discovery ensures that organizations maintain complete visibility and awareness of their full infrastructure, reducing risks and costs while enhancing overall organizational efficiency. The top 5 use cases for asset discovery include:

1. Asset Inventory

Modern asset discovery tools provide real-time monitoring to maintain accurate asset inventories, including hardware specifications, software versions, and usage metrics. The asset inventory data can be enhanced with additional context such as asset ownership, department associations, lifecycle stages, and more.

2. Change and Configuration Management

Automated asset discovery can also determine when devices join or leave the network, as well as configuration changes. The discovery tools continuously update the asset database with these ongoing changes for strategic planning.

3. Risk and Vulnerability Assessment

Advanced analytics can be applied with asset discovery to identify trends, detect anomalies, and optimize asset management strategies. Real-time discovery can also help quickly address security vulnerabilities, compliance issues, and operational inefficiencies by providing an at-a-glance view of the IT environment.

4. Software License Compliance

By automatically identifying and cataloging all software installed in their IT infrastructure, organizations can easily track how many software licenses are in use vs how many have been purchased, ensuring compliance with licensing agreements. Organizations can also avoid costly fines and legal issues, as well as identify unauthorized or outdated software that might be non-compliant with current licensing terms.

5. Cloud Resource Optimization

Cloud can often be a black box, but with asset management discovery tools organizations gain visibility into their cloud assets, including storage, services, and instances across cloud providers. This visibility enables IT professionals to identify underutilized or idle cloud resources, which can then be redistributed or reevaluated.

For real-time active, passive, and targeted network and device discovery, organizations can leverage FireMon Asset Manager to detect unknown, rogue, shadow clouds, network infrastructure, and endpoints in the enterprise.

Why Is Asset Discovery Important?

According to Forrester and the Global Tech Spend Forecast, software and IT services will account for 69% of global tech spend by 2027. This shows the growing need for asset discovery tools to track and manage organizations’ investments across their network from desktops, servers, laptops, and beyond.

By tracking assets, organizations can reduce spend, minimize waste, better allocate resources, and secure their assets. After all, you can’t secure what you can’t see.

How Does Asset Discovery Help You Understand Your Attack Surface?

Asset discovery provides organizations with a comprehensive view of their assets where they can identify every component in their infrastructure with all access points. Organizations can then identify vulnerabilities, detect rogue and unauthorized devices, better manage their hybrid environments, and respond to cybersecurity incidents faster.

What Are the Differences Between Active and Passive Discovery Tools?

The difference between active and passive discovery methods is how they collect and identify asset information. Active discovery tools actively query the network by scanning the devices and software, whereas passive discovery tools monitor the activity on the network without any probes or queries.

An active discovery tool may impact network performance due to the active scans; however, it can provide more detailed and real-time information.

Active discovery is best when an organization needs full, detailed visibility for compliance checks, vulnerability management, and auditing. Passive discovery is useful for continuous monitoring without any additional traffic on the network.
