Summary of the contracting process

Southern Water Services Limited, located in Worthing, United Kingdom, is currently in the tender stage for procuring a supplier to provide Managed Detection and Response (MDR) services. This tender is part of their initiative to enhance their IT and Operational Technology (OT) security infrastructure, ensuring continuous monitoring and threat detection across their systems. With an estimated contract value of £8.5 million for three years, there are options to extend up to two additional years. The procurement process follows an open, competitive flexible procedure dictated by the Procurement Act 2023. Interested parties must submit their responses by 21 September 2026, and the selected supplier will begin services on 1 July 2027.

This tender presents substantial opportunities for businesses in the IT and security sectors, specifically those providing consulting, software development, and support services. Companies with expertise in integrating existing security tools, like Nozomi Networks and Cisco Cyber Vision, will find themselves well-suited for this contract. The open procurement method and single supplier requirement suggest that companies with comprehensive MDR solutions can leverage this opportunity to establish a long-term partnership with Southern Water, expanding their market reach and showcasing their capabilities in regulatory compliance and innovative threat management.

Notice Title

Managed Detection and Response Tender

Notice Description

The objective of this tender is to select a single supplier to provide a combined Managed Detection and Response (MDR) service covering SWS' Corporate/IT and Operational Technology (OT) environments. SWS is seeking a 24/7/365 MDR service providing continuous monitoring, threat detection, triage, investigation, IT and OT incident response, case management, reporting and assurance evidence. The MDR Service must support SWS in meeting its regulatory and assurance obligations, including CAF, NIS and DWI requirements SWS operates an existing security tooling estate (e.g. Nozomi Networks, Cisco Cyber Vision and CrowdStrike). The MDR Service Provider will be expected to consume and integrate telemetry from these existing SWS tooling sources rather than replace them by default. Where a Tenderer identifies material gaps in the existing tooling estate, they should propose solutions to address those gaps as part of their proposed design and tender response. Estimated contract value for a 3-year contract with options to extend by 1-year and a further 1-year is PS8.5m

Lot Information

Lot 1

Options: Southern Water reserves the right to require the supplier to deliver some or all of the services in relation to Southern Water Wastewater operational technology ("OT") sites and assets, in addition to Clean Water sites and assets. Southern Water may exercise this right at any time during the contract term. Any services required for Wastewater OT sites and assets will be of the same type as some or all of the services provided by the supplier for Clean Water sites. Charges for any services required for Wastewater OT sites and assets will be determined using the cost model, tendered rates and charging basis as set out in the Commercial Response Schedule (PK-008).

Renewal: Southern Water may extend the term of the contract for an additional one year from the third anniversary of the contract start date, meaning the contract would expire four years after the contract start date. In addition, Southern Water may extend the term of the contract for an additional one year from the fourth anniversary of the contract start date, meaning the contract would expire five years after the contract start date.
