Your questions, answered.

Data Defence is led by a practising CISO with over 30 years of experience. We are not a platform or a helpdesk — we are a consultancy that takes genuine accountability for your security posture. Our cyber security and resilience service is tailored to your environment, not templated. We combine senior-level guidance with hands-on delivery and long-term partnership.

We work with established organisations that have dedicated IT functions but may not yet have a formal security management programme or 24/7 security operations capability. Our clients span Housing Associations, National Charities, Legal and IP Firms, Manufacturing, Children’s Services, Education, Software Companies, and Local Authorities.

Our 24/7 SOC capability means that active incidents are detected and triaged in real time. For clients with a managed service agreement, initial response and escalation is immediate. For advisory clients, we provide an incident response retainer that ensures a senior responder is available within agreed timeframes.

Yes. Governance, risk, and compliance support is a core part of what we do. We provide practical, hands-on support for ISO/IEC 27001 implementation and certification, Cyber Essentials Plus, the NHS Data Security and Protection Toolkit, and alignment with NCSC Cyber Assessment Frameworks — not just documentation, but genuine operational readiness.

Our engagement model is built around a three-year maturity roadmap. As your environment evolves, so does the service. We introduce new capabilities progressively — from foundational hardening through to advanced threat detection, Zero Trust, and 24/7 SOC operations — ensuring your investment scales with your needs.
