Virtual CISO

A Chief Information Security Officer provides strategic security leadership -- but most SMEs can't justify a full-time hire. Our Virtual CISO service gives you access to senior security expertise on a fractional basis, providing the strategic leadership your organisation needs without the permanent headcount cost.

Your vCISO becomes your trusted security advisor: attending board meetings, developing policy, managing supplier relationships, and ensuring your security strategy aligns with your business objectives and regulatory requirements.

02 -- Security Strategy

Security Strategy

An effective security strategy starts with understanding your business, your risks, and your obligations -- then building a prioritised, practical plan to address them. We develop security strategies grounded in real-world threat intelligence and aligned with frameworks like NCSC CAF, ISO 27001, and NIST.

The output is a clear, actionable roadmap: where you are now, where you need to be, and the practical steps to get there -- with realistic timelines and budget estimates.

Risk Assessment
03 -- Risk Assessment

Risk Assessment

Effective security investment starts with understanding your actual risks -- not just the risks that are easy to quantify or that get the most press coverage. We conduct structured risk assessments that identify, analyse, and prioritise your specific risk profile.

Our assessments cover technical, operational, and organisational risk dimensions, producing a risk register and treatment plan that enables informed decisions about where to invest and what to accept.

04 -- Compliance Advisory

Compliance Advisory

Navigating a growing landscape of security and privacy regulations is challenging. Whether you're facing UK GDPR obligations, contractual requirements for Cyber Essentials, NHS DSPT compliance, or emerging frameworks like NIS2, we help you understand what's required and build the most efficient path to compliance.

We take a pragmatic approach to compliance -- designing programmes that satisfy your regulatory obligations while minimising unnecessary overhead, and embedding compliance controls into your existing operations where possible.
