Interim CISO Services
Your CISO just left. An experienced interim CISO keeps the program, board reporting and audits on track while you hire.
When should you hire an interim CISO?
Hire an interim CISO when your security leader leaves and the program can't wait months for a permanent hire. An interim (or temporary) CISO leads your existing security team, especially when there's no clear deputy to step up, and keeps board reporting, audits and customer commitments on track. They can also help you hire and hand over to the permanent CISO. If you don't need near full-time coverage, a fractional CISO is usually the better fit.
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.
Transformation Phases: We also provide strategic advisory from interim CISOs during transformation phases like M&A, restructuring, rapid growth, and IPO readiness.
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 transition materials for your incoming CISO
How an interim CISO engagement works
- Weeks 1 to 2: take the handoff. We start within 2 weeks, lead your security team from day one, and pick up open commitments: audits, board dates, customer questionnaires and any live incidents.
- First 30 days: know where you stand. A short written assessment of the program and a plan leadership agrees to.
- Months 2 onward: run the program. Weekly with the team, a monthly summary for leadership, and board reporting.
- Hiring: find the permanent CISO. We help define the role and review candidates.
- Last 2 to 4 weeks: hand over. We document decisions and brief your new CISO. If you decide you don't need a full-time CISO, we can move to a fractional engagement instead.
Most engagements run 4 to 9 months.
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, scoped to the company's needs.
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) and no benefits or equity packages. 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 if that makes sense for your situation.
How quickly can an interim CISO start?
Most engagements start within 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.
