How to Become a CISO

A practical guide for security professionals aspiring to chief information security officer roles - and how the fractional path can accelerate your journey.

What Does a CISO Do?

The Chief Information Security Officer (CISO) is the senior executive responsible for an organisation's information and cyber security strategy. It is a role that sits at the intersection of technology, risk management, business strategy, and people leadership.

A CISO's responsibilities typically include setting the security vision, building and leading the security team, managing risk and compliance, responding to incidents, and communicating with the board. It is a high-accountability role that requires both deep technical understanding and strong commercial acumen.

Whether you aim to be a full-time CISO in a single organisation or explore the growing fractional CISO model, the foundational skills and experience are largely the same.

The Typical Path to Becoming a CISO

There is no single route to the top, but most CISOs follow a similar trajectory.

01

Build Deep Technical Foundations

Start in hands-on security roles - SOC analyst, penetration tester, security engineer, or IT risk analyst. This gives you the credibility to lead technical teams and make informed decisions later in your career.

02

Move into Leadership

Progress into management roles such as Security Manager or Head of Security. Here you learn to build teams, manage budgets, and translate security priorities into business terms.

03

Develop Strategic and Business Skills

The step from manager to CISO is about breadth. You need to understand corporate strategy, financial planning, legal and regulatory frameworks, and how to influence senior stakeholders.

04

Gain Board-Level Experience

Before becoming a CISO, most successful candidates have spent time presenting to executives, serving on committees, or leading cross-functional initiatives. Board exposure is often the differentiator.

Essential Skills for Any CISO

Technical knowledge gets you to the table. These skills get you the seat.

Leadership and team building - recruiting, developing, and retaining talent
Risk management - identifying, quantifying, and treating cyber risk
Communication - presenting complex topics clearly to non-technical audiences
Stakeholder influence - building trust with executives and the board
Crisis management - leading calmly under pressure during incidents
Business acumen - understanding finance, operations, and commercial drivers
Governance and compliance - navigating regulations and frameworks

The Fractional CISO Path

Once you have established yourself as a senior security leader, the fractional model offers an alternative to traditional full-time employment. As a fractional CISO, you work with multiple organisations on a part-time basis, providing strategic leadership without the day-to-day operational burden of a single employer.

This path suits experienced CISOs who want variety, flexibility, and greater control over their schedule. It can also be a valuable stepping stone for aspiring CISOs who want to build board-level experience across several organisations before taking a full-time executive role.
