In the water supply sector, the security of operational technologies (OT) is essential for maintaining service continuity and protecting critical infrastructure from increasingly sophisticated cyber threats. A leading water supply company faced significant challenges in early threat detection and coordinated incident response. By integrating Maltiverse Threat Intelligence with Security Orchestration, Automation, and Response (SOAR) solutions, the company transformed its OT security strategy. This integration not only automated responses to security incidents, significantly reducing response times, but also enhanced threat detection capabilities, ensuring the protection of vital assets and maintaining customer trust in a complex cyber landscape.
