Delivering end-to-end programmes of change, helping organisations mature safely in the digital era by applying a cyber security lens to business strategy.


Our increasing digital existence generates a greater need to focus on cyber security. Not only to protect against constantly evolving threats and improve business resilience, but to unlock the growth which a strong cyber security strategy enables.

Investments in technology are essential to continue delivering public services but their quick adoption is forcing organisations to embark on complex programmes and play catch up on tackling the risks they have introduced. A new proactive and strategic approach is required, moving away from the implementation of point solutions and applying incremental change.


Whether starting from a low level of maturity or needing a refresh, our experienced consultants help organisations create a resilient, agile, and secure digital environment that supports the organisation's goals and operations.

Cyber security threats are constantly evolving; we go beyond addressing the challenges of today, to help organisations embed sustainable solutions to prepare for the challenges of the future. Organisations that enable trust in systems and data can take informed risks, adapt to disruptive change and embrace change and innovation with confidence and scale.

What are the stages of cyber transformation

Every organisation has different outcome expectations from cyber transformation. Therefore, one of the most important steps of the cyber process is deciding your business’s short-term and long-term goals and objectives.
  • Stage 1 - Assess

    We rapidly assess and benchmark cyber security capabilities, identify gaps, understand exposure to cyber risks with a view to constructing a programme of work to effectively reduce those risks. At this stage it is crucial to define and understand the cyber security frameworks and methodologies that will be used for the cyber transformation.

  • Stage 2 - Review and Plan

    Once expected outcomes are set and gaps have been identified, we conduct a review to determine overall maturity levels and agree the scope of the programme. We structure and plan a programme of work that delivers a combination of quick-win tactical enhancements and long-term strategic solutions that supports both the cyber security agenda and is sensitive to the needs and capacity for change within the organisation. 

  • Stage 3 - Strategy and Operating Model

    Central to the success of the cyber transformation programme is ensuring that it supports the organisations cyber security strategy. We help define a forward-looking and sustainable security strategy and roadmap in line with business objectives. We define the target operating model which will outline the services, organisational and governance measures required to sustain an effective security posture and realise the benefits of the cyber transformation.

  • Stage 4 - Implement and Remediate

    At this stage, we help integrate cyber security into business and IT processes leveraging digital identity, application, hybrid infrastructure capabilities, and build a cyber risk-aware culture across all levels of the organisation.  We help build and optimise key cyber processes and initiatives. Transform them into a manageable, timebound roadmap to accomplish milestones in agile sprints.

  • Stage 5 - Lessons Learnt and Continuous Improvement

    Whilst implementing your cyber transformation, we measure key metrics that provide insight into how effective the programme is. We validate success, identify improvements and ensure maturity has increased, or the cyber risk has reduced. Cyber threats, technology and best practice are ever evolving, which means it's important for cyber security to evolve with it. We embed continuous improvement activities into business as usual to ensure a future-ready cyber security strategy.
