Fractional & Interim Chief Information Security Officer (vCISO)
Executive Cyber Leadership That Builds Confidence
Cyber security is no longer just a technology issue. It is a business issue that influences operational resilience, regulatory compliance, customer trust and commercial success.
Many organisations recognise the importance of experienced cyber security leadership but do not require, or cannot justify, a permanent Chief Information Security Officer.
Relentica provides experienced Fractional and Interim Chief Information Security Officers (vCISOs), giving organisations access to executive cyber leadership exactly when it is needed. Whether supporting executive teams for two days each month, leading a cyber transformation programme or providing full-time interim leadership during a period of change, we help organisations strengthen governance, reduce risk and build long-term resilience.
Our security leaders have worked across enterprise, private equity, mid-market and public sector organisations, bringing practical experience that aligns cyber security with business strategy rather than treating it as a standalone technical function.
Flexible Cyber Security Leadership
Every organisation has a different risk profile, regulatory environment and level of cyber maturity.
Some require ongoing strategic leadership to guide investment and strengthen governance. Others need experienced executive support to lead a security programme, prepare for regulatory change, improve resilience or provide stability while recruiting a permanent Chief Information Security Officer.
Our flexible engagement model allows organisations to access experienced cyber leadership in the way that best suits their objectives.
Typical Engagement Models
• Strategic Security Advisor – from 2 days per month
• Fractional Chief Information Security Officer (vCISO) – typically 1-3 days per week
• Interim Chief Information Security Officer
• Cyber Strategy & Transformation Leadership
• Board Advisory & Executive Assurance
