IT teams require visibility into their network in order to fulfil their respective duties—they may not be able to understand the relationship between devices and how they communicate with each other when network discovery is not in play. When networks experience downtime, network discovery provides response teams with relevant data, allowing them to more quickly identify and address the issue.
Hybrid networks, such as virtual, wired and wireless networks can complicate a network topology and make it difficult for IT teams to identify any root causes when an incident or issue occurs. And, as digital operations continue to increase in scale, networks are also beginning to change in terms of layout. BYOD policies and increased dependency on smart technology mean that employees are adding personal devices to the workplace. As such, monitoring basic health metrics is no longer a usable baseline—businesses must be able to use network discovery tools to have visibility of all internal activity.
Cybersecurity is also aided by network discovery, as invalid IP addresses can be identified as a sign of a malicious device that is carrying malware. IT and Security teams may use network discovery to run regular scans to identify any threats that might be sitting quietly on a network, poised for attack.
Network discovery can further improve security by helping teams identify open ports on connected devices, and inform decisions regarding which ports do and do not need to be open for business operations to run effectively.
