Case Study: Major Water Company strengthens cyber protection with PA Consulting

Improving cyber protection in the water industry

PA Consulting worked with Major Water Company, a major UK water supplier serving more than 650,000 customers, to reduce the risk of cyber attacks disrupting water services. The company was concerned about vulnerabilities created by external connections to its IT systems and wanted to understand how well its operations were protected.

PA Consulting, supported by its 7Safe technical security team, carried out a security assessment and ethical hacking exercise covering remote logins, field engineer laptops and communications, firewalls, and external-facing web applications. PA Consulting identified security gaps, provided practical recommendations to strengthen external links and improve awareness across the technical team, and helped the client move toward greater confidence in the security and resilience of its systems.
