Case Study: City of Raleigh achieves stronger OT visibility and compliance with Tenable OT Security

City of Raleigh gains visibility across 5 water plants with Tenable Networks

The City of Raleigh sought to secure its operational technology (OT) environment, which manages critical water and wastewater services. The city needed full visibility and control over changes made to devices like programmable logic controllers (PLCs) within its industrial control systems. Their challenge was to move beyond basic network monitoring to gain deep situational awareness and ensure the security of its critical infrastructure. To meet this need, they selected Tenable OT Security from vendor Tenable Networks.

The solution from Tenable Networks provided automated asset discovery, passive detection, active querying of devices, and a comprehensive audit trail. This gave the city's team full visibility into any network changes and streamlined their compliance efforts. The results included gaining massive amounts of network data within minutes instead of weeks and the ability to track who made changes to devices and when, significantly strengthening their security posture.
