AI-Powered Data Governance Secures Critical Water Infrastructure

A major government-owned water utility needed a robust solution to manage the vast and sensitive data associated with its critical infrastructure. Responsible for reservoirs, sewerage, and drainage systems across a major city, the utility holds highly sensitive operational and national security-related data. By deploying Castlepoint, the organisation achieved a centralised and secure data governance framework, ensuring compliance and risk mitigation.

The Challenge

The utility manages extensive structured and unstructured data across multiple systems, including records related to water quality, public safety, and infrastructure security. With increasing cyber threats targeting critical infrastructure, the organisation required a scalable solution to classify, monitor, and manage its information assets while ensuring compliance with strict regulatory obligations.

The Solution

The water utility first deployed Castlepoint as a proof of concept, successfully validating its ability to integrate with existing infrastructure and deliver measurable benefits. Following this, Castlepoint was rolled out enterprise-wide, transforming the utility’s approach to data governance through:

  • AI-driven classification and sentencing, ensuring all records were managed in line with compliance requirements
  • Automated risk identification, allowing high-risk data to be flagged, monitored, and tracked in real time
  • Agentless integration across diverse data environments, enabling seamless governance of structured and unstructured information
  • Enterprise-wide auditing and monitoring, ensuring all compliance obligations were met without manual oversight
  • Automated disposal of outdated records, reducing unnecessary data storage and security risks
  • Scheduled processing for critical systems, ensuring operational data remained compliant, accessible, and secure

The records management process was configured to operate invisibly to staff, enabling compliance without requiring changes to daily workflows.

The Outcome

By leveraging Castlepoint’s AI-powered governance, the water utility significantly strengthened its security and compliance posture while streamlining operational efficiency:

  • 2,163 systems registered and actively managed, providing complete visibility over all data holdings
  • 65 million key phrases mapped from over 3,000 records, improving searchability, auditing, and reporting
  • 21% of records identified as overdue for disposal, reducing unnecessary storage costs and minimising security risks
  • Improved threat detection by automating risk identification across national security-sensitive data
  • Optimised regulatory compliance, ensuring ongoing adherence to legislative obligations without resource-intensive manual processes

With Castlepoint, the water utility now has a future-proofed, AI-driven data governance framework that ensures compliance, mitigates cyber risks, and enhances the resilience of its critical infrastructure.

"Water utilities are at risk of foreign state actors and have obligations under law to minimise their data. This organisation takes this risk seriously."
