For growing SaaS companies, security leadership is no longer optional. Customers, investors, and regulators expect a documented security program led by someone with real authority.
The challenge? Hiring a full-time Chief Information Security Officer (CISO) is expensive and often premature for companies under $50M ARR. The average U.S. CISO salary exceeds $250,000 before benefits, bonuses, and stock. That’s a big investment for a business still scaling product and revenue.
Enter the fractional CISO (also called vCISO or CISO-as-a-Service). Instead of a costly full-time hire, you get experienced security leadership on a part-time basis—bringing strategy, oversight, and compliance readiness at a fraction of the cost.
A modern CISO does far more than check compliance boxes. Their responsibilities typically include:
Defining security strategy aligned with business goals
Managing risk assessments and remediation priorities
Overseeing compliance frameworks (SOC 2, HIPAA, ISO 27001, CMMC)
Vendor and third-party risk management
Incident response planning and exercises
Security awareness training across the workforce
Reporting to executives and the board on security maturity
This is a wide-ranging scope. A security engineer or IT manager can’t realistically cover all of it.
For startups and growth-stage companies, hiring a full-time CISO is often unrealistic:
Salary: $250K+ average base pay
Benefits & stock: $50K–$100K more
Recruiting fees: Often 20–30% of salary
Retention risk: Average tenure is under two years
That’s a major financial risk, especially if you only need executive-level expertise at key points.
A vCISO model fills this gap. Here’s how it works:
Engage a vCISO for 5–20 hours per month
Gain strategic leadership without the full-time overhead
Get help preparing for audits, passing reviews, and meeting customer demands
Scale involvement up or down as your company grows
Instead of paying for unused bandwidth, you invest in targeted expertise when it matters most.
A strong vCISO program provides the same deliverables as a full-time CISO, including:
Risk assessments & gap analysis – Identify and prioritize risks
Policy development & oversight – Build policies that stand up to scrutiny
Vendor management – Reduce exposure through third-party reviews
Compliance readiness – Prepare for SOC 2, HIPAA, ISO 27001, CMMC
Security training – Build awareness across the workforce
BC/DR planning – Ensure resilience through continuity planning
Penetration test oversight – Translate findings into action
Executive & board reporting – Connect technical risk to business impact
In short, you gain leadership and credibility without a $250K+ hire.
| Factor | Full-Time CISO | Fractional vCISO |
|---|---|---|
| Cost | $250K+ salary + benefits | $3K–$15K/month retainer |
| Speed to Value | 3–6 month hiring process | Often active within 2 weeks |
| Flexibility | Fixed, full-time role | Scales with business needs |
| Experience | One person’s background | Broader exposure across industries |
| Retention Risk | Average tenure <2 years | Ongoing consulting relationship |
| Tools/Templates | Built from scratch | Pre-built policies & readiness kits |
For fast-scaling SaaS companies, the vCISO model wins on cost, speed, and adaptability.
A fractional CISO makes sense if your company is:
Facing customer security questionnaires slowing down deals
Preparing for or maintaining SOC 2 compliance
Raising capital and needing stronger security posture
Relying on cloud vendors but lacking a vendor risk program
Not yet ready for the cost of a full-time CISO
If security is starting to block sales, it’s time to explore a vCISO option.
“Our IT team can handle security.”
IT is about uptime; security is about protecting data and proving trust.
“A consultant won’t understand our business.”
Good vCISOs bring proven playbooks from dozens of SaaS companies.
“Fractional means less committed.”
A strong vCISO relationship means full accountability, even if hours are fractional.
“We’ll outgrow a vCISO.”
Many companies keep a vCISO through multiple growth stages. They can even help recruit your future in-house CISO.
For most SaaS companies, the choice isn’t “hire a CISO or do nothing.” The smarter path is leveraging a vCISO—gaining real security leadership at the right scale and cost.
By doing so, you accelerate compliance readiness, reduce risk, and free your engineers to focus on building product—all without making a premature executive hire.
