As companies grow and handle more sensitive data, the need for strategic security leadership becomes critical. However, hiring a full-time Chief Information Security Officer (CISO) isn’t always feasible or necessary. Enter the fractional CISO—a cost-effective solution that provides expert security leadership when and where you need it.

What Is a Fractional CISO?

A fractional CISO is an experienced security executive who works with multiple organizations on a part-time or project basis. They provide the same strategic leadership and expertise as a full-time CISO but at a fraction of the cost and commitment.

The Evolution of Security Leadership

Traditional security models assumed companies needed either:

  • No dedicated security leadership (relying on IT teams)
  • A full-time CISO (expensive and often overkill for smaller companies)

Fractional CISOs fill the gap, providing:

  • Strategic Leadership: C-level security expertise
  • Flexible Engagement: Scale up or down based on needs
  • Cost Efficiency: Pay only for what you need
  • Immediate Impact: Hit the ground running with experience
