About Principle Defence
Security and privacy expertise, without the nonsense.
Our story
Built from experience. Driven by principle.
The security and privacy market has a problem. Too many providers lead with products. Too many audits produce reports that look thorough but don’t reflect operational reality. Too many organisations end up compliant on paper, exposed in practice.
Principle Defence was founded to challenge that. We provide risk-based, justifiable services that are specifically tailored to address your challenges — going beyond box-ticking to deliver security and privacy that actually works.
Our team's expertise spans the British Army, Big 4 consultancies, boutique firms, and in-house security roles. We've worked with clients across central and local government, and in sectors including new space, legal, logistics, oil and gas, media, financial services, software development, and telecoms.
We hold the certifications we help our clients achieve. We're a Living Wage employer. We're signatories of the Armed Forces Covenant. We try to operate as a business the way we advise our clients to — with accountability, transparency, and a clear set of principles.
To end bad security and privacy.
To help customers achieve their visions.
We: Are supportive, honest, and collaborative.
I: Have humility, integrity, and am innovative.

Our community commitment
Veteran-owned. Community-committed.
Principle Defence holds the Armed Forces Covenant Silver Award — a recognition of our commitment to fair treatment and opportunity for veterans, reservists, and Cadet Forces Adult Volunteers (CFAVs).
As a veteran-owned company, we champion the unique skills, dedication, and leadership that former service members bring to the workplace. Our inclusive hiring practices and ongoing support for veterans transitioning to civilian careers reflect a commitment that goes well beyond a plaque on the wall.
