What Northdoor plc does

Northdoor plc is a London-headquartered IT consultancy (51-100 employees, founded in the early 1990s) that delivers data-centric technology services to UK blue-chip enterprises, with primary vertical concentration in insurance and financial services, followed by public sector, retail, media, and charity sectors. The company's offering is organised around six core solution areas: Data Security (zero-trust architecture, cloud security, cyber recovery, IBM Guardium-based database activity monitoring, data discovery and classification, data masking, email security, endpoint detection and response, ransomware protection, and third-party cyber risk management); Applications, anchored by its two proprietary platforms NdexInsure (insurance and reinsurance lifecycle management including underwriting, claims, accounting and reporting) and Sanctions Checker (UK/EU/global financial sanctions screening with intelligent fuzzy search); Cloud and On-Premises Infrastructure, including IBM Power Systems modernisation; Big Data and Analytics; Artificial Intelligence (machine learning, cognitive services, intelligent bots); and IT Automation (DevOps, DataOps, Infrastructure as Code). The technology stack is anchored on Microsoft (.NET, Azure, SQL Server, multiple Silver competencies) and IBM (Premier Business Partner for Power Systems, Guardium, FlashSystem, MaaS360, Cloud Pak for Security, and the AI-assisted IBM Bob modernisation tool), supplemented by partner integrations including Egress (email security) and Geolang (data discovery).

The company operates a hybrid revenue model combining recurring managed services (managed infrastructure, managed security, managed data analytics, managed AI readiness), project-based and time-and-materials professional services (cloud migration, security assessments, legacy modernisation, bespoke development), and subscription/usage-based SaaS revenue from NdexInsure Cloud (pay-as-you-go) and Sanctions Checker (usage-based pricing tied to data volume and search complexity). Customer acquisition is driven by direct enterprise field sales targeting the City of London and UK enterprises, supported by a partner/reseller channel for Sanctions Checker via SSP, AdvantageGo (NIIT Technologies), and TGSL Group, and by G-Cloud 12 procurement access for the UK public sector. Northdoor holds ISO 27001:2022 certification and FSQS registration (2026/2027), and has won the Security Solution of the Year 2021 (European IT & Software Excellence Awards) and Security Project of the Year 2025 (Computing Security Magazine Awards). Recent inorganic activity includes the 2020 acquisition of Market Hill and the 2012 acquisition of Linksfield Technologies, alongside a strategic reinsurance technology partnership with Cenata.
