Case Study: a large local authority in the UK stops AD brute force and Golden Ticket attacks with Tenable Identity Exposure

Large local authority, UK stops Golden Ticket attacks in 3 days with Tenable Networks

A large local authority in the UK, which provides public services and handles sensitive citizen data, faced a rising number of cyberattacks and strict regulatory requirements. Their challenge was to secure their Active Directory (AD) to prevent attacks and gain real-time visibility into their security posture. They turned to Tenable Networks and implemented its Tenable.ad product for identity security.

Tenable Networks' solution provided real-time analytics and alerts, which immediately detected and notified the team of ongoing brute force and Golden Ticket attacks just two days after deployment. This enabled the security team to quickly disable compromised accounts and remove threats, preventing a potential domain takeover and data breach. As a result, Tenable Networks helped the authority avoid significant damage, potential fines, and reputational harm, ultimately saving the organization and leading to the adoption of additional Tenable products.
