What Does a Fractional CISO Career Look Like?
A fractional CISO career offers experienced security professionals the opportunity to serve multiple organizations simultaneously, providing strategic leadership without the constraints of a single full-time role. Unlike traditional employment, fractional work means you might serve 4-6 clients concurrently, each receiving 10-25 hours of your expertise monthly.
The typical fractional CISO manages a diverse portfolio: perhaps a healthcare startup needing HIPAA compliance, a SaaS company pursuing SOC 2 certification, a financial services firm requiring PCI-DSS expertise, and a manufacturing company building its first security program. This variety keeps the work intellectually stimulating while building cross-industry expertise that makes you increasingly valuable.
Most successful fractional CISOs previously held full-time CISO or senior security leadership roles for 5-10+ years before transitioning. You're not entry-level consulting—you're providing executive-level strategic guidance that only comes from experience building and leading security programs.
Income Expectations
Fractional CISO practitioners typically earn £150,000-£400,000 annually, with earnings scaling based on client load, rates, and utilization:
Year 1 (building practice): £100,000-£180,000 - As you build your client base (2-3 clients), establish processes, and prove value, expect lower initial income while investing in business development.
Year 2-3 (established): £200,000-£350,000 - With 4-6 stable clients and refined delivery processes, income stabilizes at attractive levels exceeding most full-time CISO salaries.
Year 4+ (mature practice): £300,000-£600,000+ - Top practitioners command premium rates (£400-£600/hour), serve selective high-value clients, and benefit from referral-driven business development.

Top CISO Certifications You Need
While not legally required, certifications signal expertise and are often expected by fractional CISO clients:
CISSP (Certified Information Systems Security Professional)
Importance: Critical (required by 90%+ of clients)
The CISSP is the gold standard security certification from (ISC)². It covers eight security domains including security and risk management, asset security, communication and network security, and more.
Requirements: 5 years of paid work experience in two or more CISSP domains (or 4 years with a relevant degree). Pass the 6-hour, 250-question exam covering all eight domains.
Cost: £650 exam fee + £110 annual maintenance fee
Study time: 3-6 months of dedicated preparation for most professionals
Why it matters for fractional CISOs: Nearly universal client expectation. Lacking CISSP severely limits your addressable market. Many RFPs explicitly require it.
CISM (Certified Information Security Manager)
Importance: Highly valuable (preferred by many clients)
CISM from ISACA focuses on security program management and governance rather than technical implementation. It emphasizes the managerial aspects of security—perfect for executive-level fractional work.
Requirements: 5 years of information security management experience with at least 3 years in information security management in three or more CISM job practice areas. Pass the 4-hour, 150-question exam.
Cost: £465 (ISACA members) or £575 (non-members) + £85 annual maintenance fee
Why it matters for fractional CISOs: Demonstrates management-level expertise rather than just technical knowledge. Strong complement to CISSP's technical focus.
CRISC (Certified in Risk and Information Systems Control)
Importance: Valuable for risk-focused roles
CRISC from ISACA specializes in IT risk management and control. Particularly valuable for fractional CISOs working with highly regulated industries or risk-averse organizations.
Requirements: 3 years of cumulative work experience in two or more CRISC domains. Pass the 4-hour, 150-question exam.
Cost: £465 (ISACA members) or £575 (non-members) + £85 annual maintenance fee
Industry-Specific Certifications
If you specialize in particular verticals, additional certifications enhance credibility:
- HCISPP (HealthCare Information Security and Privacy Practitioner) - For healthcare-focused fractional CISOs
- CCSP (Certified Cloud Security Professional) - For cloud-focused practices
- CISA (Certified Information Systems Auditor) - For compliance-heavy engagements
Building Your Fractional CISO Portfolio
You need proof of expertise before clients will hire you as their fractional CISO:
Start With Your Experience
Document your security leadership accomplishments:
- Security programs you've built from scratch
- Compliance certifications you've achieved (SOC 2, ISO 27001, HIPAA, etc.)
- Incident response cases you've managed
- Security budgets you've managed (shows fiscal responsibility)
- Security teams you've built or led
- Board presentations you've delivered
These become case studies demonstrating your capabilities without disclosing confidential information.
Create Thought Leadership Content
Establish yourself as a fractional CISO expert through content:
- LinkedIn posts - Share security insights, compliance tips, and industry commentary 2-3x weekly
- Blog articles - Write detailed guides on security topics relevant to your target clients
- Speaking engagements - Present at security conferences, webinars, or local CISO meetups
- Podcast appearances - Guest on security or business podcasts
Content marketing builds credibility and generates inbound leads—reducing the business development burden.
Build a Professional Online Presence
Your digital presence is your storefront as a fractional CISO:
LinkedIn profile: Update your headline to clearly indicate fractional CISO availability. List specific capabilities (SOC 2, ISO 27001, HIPAA, security program development). Include client testimonials if permitted.
Professional website: Create a simple site explaining your services, expertise areas, typical engagements, and contact information. Include case studies and testimonials.
Recommendations: Request LinkedIn recommendations from former managers, peers, and clients emphasizing your security leadership and results.
Finding Fractional CISO Jobs and Clients
Breaking into fractional CISO work requires a multi-pronged client acquisition strategy:
Leverage Your Network
60% of first fractional CISO clients come from existing professional networks:
- Former colleagues who've joined companies needing security leadership
- Professional contacts aware of your expertise
- LinkedIn connections in leadership roles at growing companies
- Industry peers who may refer overflow work
Action plan: Message 20 contacts weekly about your fractional CISO services. Focus on companies showing signs they need help: recent funding, compliance requirements, security incidents, or rapid growth.
Join Fractional Executive Platforms
Platforms connecting fractional executives with companies provide built-in deal flow:
- Fractional.quest - Marketplace for fractional executive roles including CISOs
- OnFrontiers - Premium fractional executive network
- Bolster - Fractional CXO marketplace
- Chief Outsiders - Fractional executive collective
Trade-offs: Platforms provide leads but take 20-40% margins. Good for getting started, but building direct client relationships yields higher lifetime value.
Partner Strategically
Team up with organizations that have client pipelines but lack security expertise:
- MSPs and IT consultancies - Often have clients asking about security
- Compliance consultancies - Need technical security depth for client engagements
- Private equity firms - Need portfolio company security oversight
- Accounting firms - Clients often need SOC 2 help beyond what auditors provide
Revenue share or referral fee arrangements give partners incentive to send opportunities your way.
Direct Outreach to Target Companies
Proactive outreach to ideal-fit companies accelerates client acquisition:
Ideal profiles for fractional CISO services:
- Series A-C startups (funded but pre-full-time CISO)
- 100-500 employee companies in regulated industries
- Organizations posting compliance-related jobs (signal they need security help)
- Companies recently experiencing security incidents (job postings mentioning "security incident")
- PE-backed companies undergoing operational improvements
Outreach template: "Hi [Name], I noticed [Company] recently [raised funding/posted compliance role/expanded to enterprise customers]. Many companies at your stage need CISO-level oversight but aren't ready for a £250K full-time hire. I provide fractional CISO services to [3-4] companies in [industry]. I've helped similar organizations achieve [SOC 2/ISO 27001/etc.] in 4-6 months. Would a brief 20-minute call about your security priorities make sense?"
Setting Your Fractional CISO Rates
Pricing your fractional CISO services balances market rates, your expertise, and client value:
Hourly Rate Calculation
Start with your full-time CISO salary equivalent and work backwards:
Target annual income: £200,000
Billable hours (80-100 hours/month): 1,000 hours/year (assuming some unbillable time for business development, administration)
Required hourly rate: £200,000 ÷ 1,000 hours = £200/hour minimum
Add 30-40% for business overhead (taxes, healthcare, insurance, tools, unbillable time): £200 × 1.35 = £270/hour
Starting rate: £270-£300/hour
As you gain experience and build your practice, rates scale to £350-£500/hour for senior practitioners.
Monthly Retainer Pricing
Most clients prefer predictable monthly retainers over hourly billing:
- 15 hours/month × £300/hour = £4,500/month
- 25 hours/month × £300/hour = £7,500/month
- 35 hours/month × £300/hour = £10,500/month
Round to clean numbers: £5,000, £8,000, £10,000 monthly retainers.
Value-Based vs Time-Based Pricing
For defined projects (SOC 2 certification, security program buildout), consider value-based pricing:
SOC 2 Type I project: Instead of "40 hours at £300/hour = £12,000," price based on value: "SOC 2 certification unlocks £2M in enterprise deals for you. My £30,000 fixed-fee engagement delivers certification in 4 months with all necessary controls and audit support."
Value-based pricing aligns incentives (you're rewarded for efficiency) and often yields higher effective hourly rates.
Legal & Business Setup for Fractional CISOs
Operating as a fractional CISO requires proper business structure:
Business Entity Options
Limited Company: Most common UK structure for fractional CISOs. Provides liability protection and tax efficiency. Costs £12-£50 to incorporate.
Sole Trader: Simplest structure but offers no liability protection. Less tax efficient than limited company beyond £50,000 income.
Essential Insurance
- Professional Indemnity Insurance: Critical for fractional CISO work. Covers claims of professional negligence. Cost: £500-£3,000 annually depending on coverage limits (£1M-£5M typical).
- Public Liability Insurance: Covers injury or property damage. Cost: £100-£300 annually.
- Cyber Liability Insurance: Covers data breaches and cyber incidents. Increasingly expected. Cost: £500-£2,000 annually.
Contracts and Agreements
Have a solicitor review or draft your fractional CISO service agreement covering:
- Scope of services (strategic guidance vs. hands-on implementation)
- Liability limitations (cap at contract value or insurance limits)
- Confidentiality and data protection
- Intellectual property (work product belongs to client)
- Termination terms (30-60 days notice typical)
- Non-compete and non-solicitation clauses (carefully negotiate—you need to serve multiple clients)
Managing Multiple Clients as a Fractional CISO
Juggling 4-6 fractional CISO clients requires discipline:
Time Blocking
Assign specific days or time blocks to each client:
- Client A: Monday mornings + Thursday afternoons
- Client B: Monday afternoons + Friday mornings
- Client C: Tuesday + Wednesday mornings
- Client D: Wednesday afternoons
Prevents constant context-switching while ensuring regular engagement with each client.
Communication Cadence
Establish regular touchpoints with each fractional CISO client:
- Weekly 30-minute check-in call (for higher-hour retainers)
- Bi-weekly 1-hour strategic meeting
- Monthly written report on security posture and progress
- Quarterly business review with executive leadership
Regular cadence prevents urgent "emergency" requests that disrupt your schedule.
Tools for Managing Fractional Practice
- Time tracking: Harvest, Toggl, or Clockify to track client hours
- Project management: Asana, Monday, or ClickUp to manage deliverables across clients
- Document management: Google Drive or Dropbox with client-specific folders
- CRM: HubSpot or Pipedrive to manage client relationships and business development
- Invoicing: FreshBooks, Xero, or QuickBooks for professional invoicing
Common Mistakes to Avoid
New fractional CISOs often stumble on these issues:
Taking On Too Many Clients Too Fast
Start with 2-3 clients and prove you can deliver consistently before scaling to 5-6. Overcommitment leads to burnout and poor client outcomes.
Underpricing Your Services
Charging £150/hour when you should charge £300 means working twice as hard for the same income. Price based on value delivered, not just market rates.
Failing to Set Boundaries
Clients will consume all available time if you let them. Set clear boundaries on availability, response times, and scope creep.
Neglecting Business Development
When you're busy with clients, business development feels unnecessary. Then a client leaves and you have no pipeline. Dedicate 10-20% of time to BD even when fully booked.
Conclusion: Is a Fractional CISO Career Right for You?
A fractional CISO career offers experienced security leaders autonomy, diversity, and earning potential exceeding most full-time roles. However, it requires self-direction, business acumen, and comfort with income variability.
