Interim CISO Services
Your CISO just gave notice - or was asked to leave. You have 30 days or less, no strong deputy to step up, and a leadership gap that could last 6 months while you search. We provide experienced security leadership to bridge that gap, maintaining program momentum and stakeholder confidence while you find the right permanent hire. We also provide strategic advisory from interim CISOs during transformation phases like M&A, restructuring, rapid growth, and IPO readiness.
When You Need Interim Leadership
Common Interim CISO Scenarios
CISO Departure: Your security leader resigned or was let go. Security programs need consistent leadership - without it, initiatives stall, teams lose direction, and risks accumulate.
Extended Search: Executive security hires take 4-6 months on average. During that time, board reporting, compliance obligations, vendor assessments, and strategic decisions don't pause.
Organizational Change: M&A activity, restructuring, or rapid growth created a temporary need for security leadership while you determine the right permanent structure.
Leave of Absence: Medical leave, sabbatical, or other extended absence requires experienced coverage to maintain continuity.
What We Do as Your Interim CISO
Maintaining Program Momentum
We step in as your acting CISO, providing the strategic leadership your security program needs during the transition:
- Board and Executive Reporting: Continue regular security updates to leadership and the board, maintaining stability and confidence
- Team Leadership: Keep your security team focused, motivated, and productive during uncertain times
- Vendor and Partner Management: Maintain relationships with security vendors, auditors, and partners
- Compliance Continuity: Ensure audit schedules, compliance obligations, and certification renewals stay on track
- Incident Response: Provide experienced leadership if security incidents occur during the transition
- Strategic Decisions: Make informed decisions on security investments, staffing, and priorities that can't wait
Supporting the Transition
Beyond maintaining operations, we help set up your next CISO for success:
- Documentation: Ensure program documentation, policies, and procedures are current and accessible
- Stakeholder Relationships: Maintain and strengthen relationships across the organization
- Hiring Support: Help define the role, evaluate candidates, and brief finalists on program status
- Onboarding Prep: Create comprehensive transition materials for your incoming CISO
Interim vs. Fractional CISO
Interim CISO vs. Fractional CISO
Interim CISO is a temporary, intensive engagement designed to bridge a specific gap. We act as your CISO during a defined transition period, typically 3-9 months, with higher time commitment and full accountability for the security function.
Fractional CISO is an ongoing, part-time engagement for companies that need strategic security leadership but not a full-time executive. This is a longer-term relationship with engagement levels of 25, 40, or 80 hours per month.
Which do you need?
Choose interim if: Your CISO just left, you're actively hiring a replacement, and you need someone to maintain full accountability during the search.
Choose fractional if: You don't have (or need) a full-time CISO, and you want ongoing strategic guidance on a part-time basis.
Many interim engagements transition to fractional relationships if the company decides not to hire a full-time CISO, or we can step back entirely once your permanent hire is onboarded.
Common Questions
What's the typical engagement length?
Most interim engagements run 4-9 months, covering the transition period plus time to onboard the permanent replacement. We're flexible on duration and can extend or shorten based on your hiring timeline.
How much does an interim CISO cost?
Interim CISO pricing is comparable to what you'd pay a full-time CISO, but without the associated costs of a permanent hire. There are no recruiting fees ($50K-$100K savings), no benefits or equity packages, and no long-term commitment. You get immediate experienced leadership for a defined period rather than a multi-year employment relationship.
Can you help us hire the permanent CISO?
Yes. We work with your recruiting and people team to define the role, review candidates, and ensure the job description reflects what the program actually needs. We also prepare transition materials and support onboarding when your new hire starts.
What if we decide we don't need a full-time CISO?
That's a valid outcome. Some companies discover during the interim period that fractional CISO services better fit their needs. We can transition to an ongoing fractional engagement at 25, 40, or 80 hours per month if that makes sense for your situation.
How quickly can an interim CISO start?
We can typically begin within 1-2 weeks. The initial focus is rapid onboarding: understanding your environment, meeting key stakeholders, and ensuring continuity of critical functions. Most interim CISOs are operationally effective within the first 2-3 weeks.
What's the difference between interim CISO and acting CISO?
The terms are often used interchangeably. Both refer to temporary security leadership during a transition period. 'Interim' emphasizes the temporary nature while you search for a permanent hire; 'acting' emphasizes that the person is performing the CISO role during the gap. The responsibilities and engagement are essentially the same.
