What does a Fractional CISO do?
A fractional CISO carries the CISO accountability across two to five client organizations at once. The economics work because most companies under 500 employees cannot justify a full-time CISO salary but face the same regulatory, contractual, and incident-response demands as a Fortune 500. You spend a day or two per week per client, attend their board cybersecurity briefings, sign off on their SOC 2 attestations, and answer the customer-security questionnaires that come in faster than any internal team can absorb. The role is structurally suited for senior practitioners with executive presence who would rather work across multiple problems than embed in one organization. Cynet's 2024 Fractional Security Leader Report sized the US fractional-CISO market at roughly 8,000 active practitioners, growing as mid-market regulatory pressure (NYDFS Part 500, SEC cyber rule, state breach notification laws) compounds.
A day in the role
Wednesday, 7:30 AM. You start with the smallest client of the morning, a 60-person fintech in pre-Series B. You join their weekly engineering standup as the security advisor, sign two RFP security-questionnaire responses, and approve the rotation of their AWS root credentials. 10:00 AM you switch to a 200-person healthcare-tech client; their CTO needs your sign-off on a HIPAA-relevant vendor renewal. Lunch is your only buffer hour. Afternoon you meet with the largest client's audit committee for their quarterly cybersecurity briefing, walk through three incident-response simulations, and answer board-member questions about the SEC cyber rule. By 5:00 PM you triage Slack messages from the other clients you didn't see today.
Core responsibilities
- Carry executive accountability for cybersecurity outcomes across 2-5 client organizations
- Brief client boards and audit committees on cybersecurity posture, incidents, and roadmap progress
- Sign off on SOC 2 reports, ISO 27001 audits, and customer security attestations
- Lead incident response when a client faces ransomware, BEC, or vendor compromise
- Hire and coach the in-house security team the client will need at scale
- Negotiate cyber insurance renewals and answer underwriter questionnaires
- Set quarterly cybersecurity OKRs aligned to each client's industry and stage
- Maintain bench depth so a single client incident does not collapse the rest of the book

Tools you will use
MITRE ATT&CK tactics this role touches
Common pitfalls
- Taking on too many clients and missing an incident on the smallest one
- Failing to set escalation thresholds, so every client question becomes urgent
- Treating each client's security stack as a generic problem instead of their specific industry context
- Not maintaining at least one peer fractional CISO as a backup for vacation or illness coverage
