Top IT Asset Discovery Tools in 2025 to Protect your Business

Any business that relies on technology to run its operations needs to have some form of asset discovery in place. Asset discovery refers to identifying and cataloging an organization's hardware and software assets. This information helps to generate an inventory that can be used for various purposes, such as compliance with regulations, managing assets, and troubleshooting technical issues—the larger the assets, the more pain points associated with putting them in order.

For example, many businesses are required to comply with regulatory requirements such as Sarbanes-Oxley, HIPAA, PCI DSS, and others. Failing to comply with these regulations can result in heavy fines or criminal charges. Asset discovery tools can help businesses inventory their assets and ensure compliance by providing detailed reports on what is installed on each device on the network. This article will overview what IT asset discovery tools are and how they can help your organization.

What is asset discovery in IT?

IT asset discovery tools are software programs used to identify and track an organization's hardware and software assets. They provide organizations with a comprehensive view of their assets, including information about the location, age, and condition of each asset. This information is important for a number of reasons, including asset management, compliance, security, and cost savings. IT asset discovery tools can be used in a variety of settings, including businesses, government agencies, and educational institutions.

There are 2 types of IT asset discovery—active and passive. Let's look closer at them.

What is an active IT asset discovery?

An active or standard asset discovery approach involves going over a network and trying to ping each of the devices that come into contact with it. This method would typically involve a lot of configuration. Although this approach works well in most cases, it can be insecure and can affect the network in a lot of cases. 

What is a passive IT asset discovery?

The other approach is called the passive asset discovery syslog. This involves taking a log message and storing it in a log management solution. The live data would be considered as live data, as it would have to be continuously updated by the log management solution in order to create the asset. With the advent of the passive asset discovery method, organizations can now create assets from both live and historical data. This method allows them to pull in data from various sources, such as archived syslog messages.

One example would be allowing organizations with different geographic regions to copy over the archived logs from their local syslog to a central repository. This method would allow the head office to identify potential security breaches.

The tools used for monitoring and identifying assets related to your information technology infrastructure. To be more specific we can notice several useful features as:

• Monitoring and risk scoring
• Troubleshooting network devices
• Identification of hacking attempts, leaked data
• Discovering vulnerable and outdated software
• Pen testing tools
• Mapping network devices
• Standardizing and centralizing the processes of multiple site management
• SQL queries and PRTG sensors for monitoring databases and detailed statistics
• Internal audit compliance
• Managing software licenses
• Gather information about device status, packet loss, response times

How the asset discovery process works

The concept of asset discovery is a process that enables enterprises to find the location and status of their non-physical assets. These include devices and software that are not yet physically tied to a physical building.

Until recently, the asset discovery process was mainly focused on finding physical products or installing software. With the advent of cloud computing, it has become possible to discover and monitor the various components of an organization's infrastructure.

We prepared a typical comprehensive enterprise IT discovery process:

The asset discovery process can be performed in various ways depending on the type of hardware and software products that an organization has. 

Also, it is worth mentioning that there are two types of asset discovery systems: manual and automated. Automated asset discovery systems pull information about the assets into the hands of the appropriate software agents. These systems do not require the owner or employees to do anything. Manual asset discovery systems usually use humans to input data about an asset. In other words, both types of asset discovery systems operate by broadcasting the details of the assets to the appropriate software agents or tags. The only difference is in "hands" behind the process. 

Here is how data flow happens with data discovery tool in an organization:
