NW2237 -the provision of OT Anomaly Detection Solution (Hardware, Software, Implementation & Support)

Northumbrian Water Limited (NWL) provide water and sewerage services to just under 4.4 million people operating principally in the North-East of England and Essex and Suffolk. It is NWL's vision 'to be the most digital water company in the world' therefore it is our mission to find a partner to support our Developer Services Product.

NWL would like to identify a partner to supply and help implement an OT Anomaly Detection solution with the right functionality that supports our business needs and provides future flexibility as our business evolves and grows its cyber capabilities.

Northumbrian Water Limited (NWL) has a regulatory requirement to implement an Operational Technology (OT) anomaly detection solution as part of our cyber resilience enhancement programme. This programme aims to deliver multiple benefits across the company by enhancing our cyber security strategy, processes, and tools to ensure compliance with the Network and Information Systems (NIS) Directive.

A key part of our cyber resilience enhancement programme is to improve the security posture of our OT estate and after recently implementing a managed hybrid Security Operations Centre (SOC), we aim to bring our OT monitoring, detection, and response in line with our existing IT capability. To effectively integrate with our SOC, any OT anomaly detection system must be capable of sending alerts (at minimum) to our SIEM (Splunk Cloud).

In addition to the security monitoring enhancements the OT anomaly detection system will bring to our compliance with the NIS Directive/Regulations, the additional asset discovery and vulnerability identification are key areas in which we expect the solution to assist.
