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 £8.5m ## CPV classification IT services: consulting, software development, Internet and support Computer support and consultancy services Source Find a Tender (UK) · Notice ocds-h6vhtk-0606ff-2026-08-12T09:41:52+01:00 [View official notice](https://www.find-tender.service.gov.uk/Notice/ocds-h6vhtk-0606ff-2026-08-12T09:41:52+01:00) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
