Building organisations that are more resilient, better protected and faster to recover.
COR5 helps organisations understand their exposure, strengthen their defences and maintain operational continuity in the face of cyber threats, fraud and disruption.
An integrated view of organisational resilience.
COR5 is a United Kingdom-based cybersecurity and resilience consultancy. The name describes what we do: Cyber Operational Resilience, supported by four further capabilities — Fraud, Intelligence, Vulnerability and Enhancement.
Our integrated approach combines these five disciplines to provide a comprehensive view of organisational resilience — from identifying emerging threats and weaknesses to strengthening controls, response capabilities and long-term security maturity.
Most organisations buy security services one at a time: a penetration test here, a maturity assessment there, a threat feed somewhere else. The findings rarely meet. COR5 exists to close that gap — to connect what intelligence tells you is coming, what testing tells you is exposed, what fraud data tells you is already being exploited, and what your organisation actually needs to keep running.
Prepare. Protect. Detect. Respond. Recover. Enhance.
- Prepare — know your critical services, dependencies and exposure before disruption arrives.
- Protect — strengthen the controls that stand between a threat and a business impact.
- Detect — see attacks, fraud and compromise earlier, when the cost is still low.
- Respond — act with clarity, defined roles and decisions already rehearsed.
- Recover — restore critical services within timeframes the business can absorb.
- Enhance — improve continuously, so the next incident meets a stronger organisation.
Five letters. Five capabilities.
Each capability answers a different question about your organisation — and together they answer the one that matters: could we keep operating?
Cyber Operational Resilience
Could we keep running? The ability to anticipate, withstand, respond to and recover from cyber disruption while maintaining critical business operations.
Fraud
Where are we losing money and trust? Understanding fraud exposure across processes, channels, products and customer journeys — and closing it without punishing legitimate users.
Intelligence
What is coming for us? Turning complex threat information into concise, actionable intelligence that security teams and boards can both act on.
Vulnerability
Where are we exposed? Identifying, prioritising and remediating weaknesses across infrastructure, applications, cloud and the external attack surface.
Enhancement
Are we getting better? Raising maturity through strategy, governance, architecture and culture, with improvement that can be measured rather than asserted.
COR + FIVE
Cyber Operational Resilience at the centre, four capabilities around it, and one integrated view of where your organisation actually stands.
Security expertise with an operational mindset.
Business-led
We connect cybersecurity decisions to business objectives, operational priorities and measurable outcomes.
Intelligence-led
We use threat and risk intelligence to help organisations focus on what matters most.
Practical
Our recommendations are designed to be implemented — not simply added to a report.
Integrated
Cyber resilience, fraud, intelligence and vulnerability cannot operate in isolation. We bring them together.
Continuous
Resilience is not a one-off project. We help organisations continuously assess, improve and adapt.
Board-ready
We translate technical risk into clear business language, enabling better decisions at every level of the organisation.
Resilience is not about preventing every incident.
It is about being prepared for the incidents you cannot prevent — understanding your exposure before it is exploited, responding with clarity when it matters, and recovering quickly enough that your organisation keeps moving.
Let's talk about what you need to protect.
