How is asset detection primarily achieved by Tenable products?

Asset detection in Tenable products is primarily achieved through network scanning methodologies. This approach allows for the active identification and inventory of devices and services within a network. By scanning the network, Tenable products can discover various assets, assess their security posture, and gather detailed information about their configurations, operating systems, and potential vulnerabilities.

Network scanning takes advantage of protocols and services available in the network environment, enabling a comprehensive view of assets connected to the network. This capability is essential for organizations aiming to maintain an up-to-date inventory of their IT environment and identify any potential security risks associated with their assets.

Other methods like manual entry or agent-based scanning may contribute to asset identification, but they do not provide the same level of comprehensive visibility or efficiency as network scanning. Additionally, focusing solely on public IPs would limit the detection process, as many assets may exist within private IP ranges that are not visible through public scans.
