How we work
Train. Support. Lead.
Your organisation’s security and privacy needs are unique. Principle Defence was founded to move beyond box-ticking delivering services that are risk-based, justified, and built around your challenges.
Train
We train and certify your staff to conduct security, cyber, risk, and privacy activities independently. As qualified instructors registered with the BCS, The Open Group, APMG, and TQUK your team learns from practitioners, not theorists.
Support
From pre-audit preparation to incident response and discrete project work, our consultants integrate with your existing team on a flexible, sliding-scale basis tailored to your timetable and budget.
Lead
With over 60 years of combined experience, our consultants can take full ownership of your cyber security, risk management, and data privacy activities freeing you to focus on running your organisation.
Client feedback

Jim and the team demonstrated deep knowledge of the standard, guiding us through each stage with clarity and professionalism. Their practical approach made the audit feel like a genuine opportunity for improvement.
