How Much Does a Fractional CISO Cost?
As of September 2026, a fractional CISO (vCISO) costs $8,000 to $25,000 per month, depending on scope and complexity; a full-time CISO costs $300K to $500K+ fully loaded once you add salary, benefits, equity, and recruiting. That makes a fractional CISO often less than half the cost of a full-time hire.

What Affects Fractional CISO Pricing?
Level of Involvement
Scope is set to your company's needs, from strategic oversight to hands-on program leadership, with interim arrangements for near full-time coverage.
Scope of Work
Assessment-only engagements cost less than ongoing security leadership. Compliance projects (SOC 2, HIPAA) may have higher initial costs.
Company Complexity
Multi-cloud environments, regulated industries, and larger employee counts typically require more intensive engagement.
Urgency
Post-incident response or urgent compliance deadlines may require higher initial investment to accelerate timelines.
Right-Sizing the Engagement
Cost follows scope, and scope changes as your program matures. A good fractional CISO adjusts the engagement with you:
- Start with an assessment so the scope matches what your program actually needs
- Scale up while building the program, preparing for an audit, or responding to an incident
- Scale back to strategic oversight once the program runs
- Move to interim coverage if your full-time CISO leaves
