The CISO of a major international retail bank reframed cyber security as an enterprise issue, not just a technology issue.
This case study explains how PYXIS helped the bank map causal risk factors beyond technology, prioritise high-impact interventions, and engage the board with a clearer, organisation-wide view of cyber security risks.
Client challenge
Cyber risk was seen as a technology silo, not a business issue.
The bank’s Chief Information Security Officer (CISO) struggled to get support from other functions because cyber security was viewed primarily as a technology problem. Traditional cyber briefing documents were too detailed and technical for business leaders and the board, and cyber budgets were nested within the broader Technology budget. Trust and customer loyalty were at risk due to ongoing breach costs and long detection times.
Reframing cyber security
The CISO shifted the narrative to enterprise-wide responsibility.
Recognising that human and organisational factors drive most security failures, the CISO engaged PYXIS to help reframe cyber security as a shared business responsibility. This reframing set the stage for a broader culture change agenda and stronger collaboration across functions.
Mapping cyber security causal factors
A facilitated workshop uncovered hidden risks.
PYXIS guided the bank’s cyber leadership team through a three-hour workshop to identify organisational causal factors that drive employee actions on cyber security.
Beyond training and phishing exercises, the team identified factors including:
Complex internal IT and cyber policies
Cumbersome work processes
Supervisor demands for cost control
Peer pressure not to report mistakes
Weak third-party cyber practices
Poor oversight of access management
Lack of alignment between physical, IT and cyber security
Limited support from senior leadership and the board
This ecosystem view revealed risk drivers that traditional assessments often miss.
Identifying systemic cyber risks
Quantitative and qualitative data strengthened the model.
To build a rigorous, data-driven model, the team spent a week gathering internal company data including historical cyber metrics and employee engagement surveys. A tailored cyber security

culture assessment was sent to managers and supervisors, and the PYXIS algorithm generated numerical and colour-coded scores for each causal factor, as well as an overall cyber security effectiveness score.
Scenario planning and prioritisation
Modelling interventions supported evidence-led decisions.
The PYXIS platform includes a library of best practices linked to specific risk causal factors. The bank’s team used the platform’s scenario planning function to model potential cyber security improvements and calculate estimated ROI for each.
Initiatives selected for focus included:
Strengthening engagement with business leadership
Increasing oversight of third-party suppliers and contractors
Improving risk management practices
Revising cyber policies and processes for easier compliance
This prioritisation process helped the bank focus resources on changes that would have the most impact.
Linking culture to business metrics
Visibility into performance supported governance.
The platform also linked the cyber security culture map to key business metrics. This capability allowed the bank to track internal practices relative to outcomes and adjust focus as needed. By showing metrics that mattered to leaders, the bank could monitor progress and keep cyber security aligned with broader business performance goals.
Engaging the board and senior leaders
Visual maps made discussions more effective.
With the visual culture maps, the CISO was able to communicate cyber security risk in business terms, avoiding dense technical reports. Boards and senior leaders could see where vulnerabilities were emerging and prioritise strategic conversations around risk mitigation. This deeper engagement helped move cyber security from a cost centre to a business-partner function supporting enterprise goals.
Outcomes and impact
Cyber security became a shared organisational priority.
The bank achieved a shift in how cyber security was understood internally:
Clearer alignment between cyber priorities and business goals
Better prioritisation of interventions based on systemic risk drivers
Enhanced board oversight with metrics leaders could interpret
A stronger enterprise approach to risk that extended beyond technology
This case illustrates how addressing cultural drivers and causal factors can materially improve an organisation’s cyber resilience.
