Enterprise-grade cybersecurity auditing, compliance, and monitoring solutions to SMEs, schools, charities, and public sector bodies.
At Cyber Defence Office (CDO), our mission is simple: to protect organisations that serve the public good. We provide enterprise-grade cybersecurity auditing, compliance, and monitoring solutions to SMEs, schools, charities, and public sector bodies—organisations often overlooked by traditional providers. Our work is guided by a commitment to make robust digital security accessible, affordable, and ethically delivered.
As a registered Company, CDO operates not for profit, but for public value. Every pound we earn is reinvested into improving services, supporting community initiatives, and expanding access to cybersecurity education. We exist to build safer digital spaces not just for our clients, but for the communities they serve.
Expertise You Can Trust, Tailored for Real-World Risks
Our team is made up of industry-certified specialists holding qualifications such as CompTIA Security+, ISO 27001 Lead Auditor, and CISSP. With decades of combined experience, we bring the same level of professionalism and rigour you’d expect from a large security consultancy—delivered in a practical, mission-focused way tailored to your organisation.
We don’t believe in one-size-fits-all security. Whether you’re looking for a one-off cyber audit, help achieving compliance, or 24/7 SOC monitoring, our services are designed around the unique needs of your sector. We understand the constraints faced by growing organisations and work closely with you to deliver clear, actionable protection that fits your operations.
Every organisation we protect strengthens the wider ecosystem. We’re working to close the cybersecurity gap in the UK by empowering the organisations that matter most.
Cybersecurity isn’t a one-time project—it’s an ongoing process. That’s why we offer continuous monitoring, monthly updates, and quarterly strategy reviews to ensure your defences stay strong and scalable as your organisation evolves. We’re more than a vendor—we’re a trusted security partner committed to your long-term success.
