NetSec Trends Report: Water Sector
A strategic report detailing the convergence of network and security operations (NetSec) within the water sector. It provides a roadmap for securing Critical National Infrastructure against aging OT, climate volatility, and evolving cyber threats. Break down silos between network and security to protect critical infrastructure against evolving threats and regulatory pressure.

Water utilities operate in some of the most sensitive environments in the UK. Today, maintaining safe, continuous service requires more than just engineering excellence—it requires a unified approach to digital resilience. As OT and IT environments merge, the traditional gap between network and security teams has become a significant vulnerability.
This trends report, "Securing Water Infrastructure through NetSec Convergence," offers a practical framework for the water sector. Drawing on deep experience in Critical National Infrastructure (CNI), it outlines how to stabilize legacy environments while building an intelligent, AI-driven defense that meets NIS2 standards and protects against climate and cyber risks.
Key Highlights:
The Erosion of Isolation: Traditional "air-gapped" OT security is failing as infrastructure becomes more IP-connected and remote-access dependent.
Converging Pressures: Utilities must simultaneously manage aging assets, climate volatility, and heightened cyber-threat activity.
NIS2 Compliance: The urgent need to meet stricter regulatory requirements for reporting and risk management in critical infrastructure.
NetSec Convergence Defined: The strategic alignment of Network and Security operations to create a unified defense posture.
Visibility Gaps: Why siloed teams often miss threats that move laterally between IT and OT environments.
Cloud-Native Connectivity: Leveraging secure, cloud-based architectures to improve network performance and visibility.
AI-Driven Observability: Using artificial intelligence to detect anomalies in sensitive operational environments before they cause service disruption.
Stabilizing Legacy Environments: A pragmatic approach to securing old infrastructure while transitioning to modern digital platforms.
The "Single Pane of Glass": Creating integrated NOC/SOC operations to streamline monitoring and incident response.
Sustainable Transformation: Moving beyond reactive risk management to build a foundation for long-term innovation.
Collaborative Resilience: Ensuring people, processes, and technology work in harmony to protect essential community services.
