What D2 NETWORK ASSOCIATES LIMITED does
D2 Network Associates Limited (D2NA) is a privately held UK cyber security services company founded in 2005 and headquartered in Cheshire. The company operates a remote-first delivery model and offers a unified portfolio split between Assurance services (Penetration Testing, Vulnerability Management, Configuration Reviews, Social Engineering, OSINT, Governance/Risk/Compliance, and Cyber Essentials/Plus certification as an IASME Certification Body) and Operations services (CREST-accredited Security Operations Centre, Service Desk, and end-to-end IT Project Services). All service delivery is shaped by D2NA's proprietary CyberAscend five-stage framework (Initiate, Discover, Remediate, Confirm, Continue), aligned with NCSC best practices and the Microsoft security ecosystem; productised extensions include the D2Aware awareness/training platform and the Salus penetration testing portal.
Underlying technology is built around Microsoft Security and Microsoft AI Business Solutions partnerships, with Elastic for security analytics/search and Vanta for compliance automation. The company holds CREST accreditation for its SOC, Penetration Testing, and Vulnerability Assessment, plus ISO 27001 and ISO 9001 certifications.
The business model is a mix of recurring managed services (SOC monitoring, MDR), subscription-style assurance retainers, project-based professional services, and Cyber Essentials certification fees. Pricing is quote-based, with a complimentary 30-minute 1:1 specialist consultation offered as the primary top-of-funnel engagement. Go-to-market is sales-led and direct, targeting mid-market and enterprise clients across security-critical UK verticals including construction, local and regional government, police, fire & rescue, healthcare, finance, manufacturing, and retail, supported by events (CyberFusion, industry exhibitions), content marketing, and regional community engagement. The company is founder-led (Founding Director Graham Doyle) with no disclosed external investment or parent entity.
