When something goes wrong, and at some point it will, the difference between a managed recovery and a damaging crisis often comes down to one thing: preparation.
I’m Jon Pertwee, an independent consultant based in Switzerland. I work with organisations of all sizes to build disaster recovery and business continuity programmes that are genuinely fit for purpose, not just compliant on paper. My approach draws on decades of practical experience, a deep grounding in information security, and frameworks developed through real-world implementations with international organisations, multinationals, and growing businesses.
Whether you’re starting from scratch, reviewing existing plans, or preparing for a serious test, I’d welcome the chance to help.
Disaster Recovery
Design, implement, and test disaster recovery strategies that work when it matters most. I use a proprietary layered framework to uncover cascading failures and hidden dependencies that standard approaches miss.
Business Continuity
Build organisation-wide resilience that goes beyond IT recovery. From ISO 22301 implementation to crisis management frameworks, I help you keep critical operations running through any disruption.
Information Security Management
Security and resilience are inseparable. I bring CISSP-level expertise to ensure your recovery strategies remain secure under pressure — covering governance, risk management, ISO 27001, and GDPR compliance.
New Publication – 2025
An IT Manager’s Guide to Disaster Recovery
A practical, no-nonsense guide to building disaster recovery programmes that actually work. Written for IT managers and consultants who need to move beyond compliance and deliver real-world resilience.
A Consultant Who Has Seen What Happens When Plans Fail
Over more than 20 years I’ve worked with multinational corporations, UN agencies, and growing businesses, plan for, and more importantly, recover from disruption. I’ve delivered and tested over 30 disaster recovery plans, authored two books on the subject, and developed frameworks that continue to evolve through ongoing research.
I work independently, which means you get direct access to my expertise, not a junior consultant with my name on the cover letter, or an agency that finds the expert after they have secured the contract.
Advancing Disaster Recovery Through Research
My consulting practice is informed by active academic research. I’m pursuing doctoral studies in disaster recovery, with a specific focus on applying complexity theory, including Nonlinear systems, network theory, and self-organisation, to understand why recovery strategies succeed or fail in real-world conditions.
I’m currently seeking organisations willing to participate as research partners. In exchange for contributing anonymised data, partners receive a comprehensive infrastructure analysis and cascading failure assessment, at no cost.
Let’s Talk About Your Resilience
Whether you’re concerned about a specific risk, reviewing an existing DR plan, or building a resilience programme from the ground up — I’m happy to have an initial conversation with no obligation.
