By the second half of 2025, the math on hiring a Chief Information Security Officer for a small or mid-market organization had shifted decisively. The base salary was up. The fully-loaded cost was up. And the alternative, a fractional vCISO retainer with a credible firm, had matured enough that the cost gap was no longer an unfair comparison.
The IANS Research and Artico Search 2025 CISO Compensation Benchmark put a number on the first half of the equation: CISO total compensation grew 6.7% year over year in 2025, even as broader economic conditions and the rest of the executive talent market softened. The CISO role kept rising in compensation because the underlying demand for the role kept rising. The data is in the public record, and the implication for SMB and mid-market organizations is sharp.
For a business that does not have a forced compliance regime requiring a named C-suite security executive (most SMBs and many mid-market firms), the case for hiring full-time was thin by Q3 2025 and thinner by Q4. Here's the actual math, where it favors fractional, and where it doesn't.
The full-time cost is not just the salary.
Salary.com's Phoenix benchmark for the Chief Information Security Officer role puts the average base salary in the metro at $380,591, with the 75th percentile reaching $424,765 and the 90th percentile beyond. That is base salary alone. Phoenix is a major metro but not at the top of the compensation table: San Francisco, New York, and Boston run higher. Smaller metros run lower, but rarely by the percentage hiring managers expect.
The IANS Research data extends the picture into total compensation rather than just base. The benchmark reports CISO compensation rising 6.7% in 2025, with total compensation (base + bonus + equity where applicable) substantially higher than the base figure for mid-market and enterprise organizations.
The fully-loaded cost (base, bonus, equity vesting, benefits, payroll taxes, recruitment fees if the role is hired externally) typically runs 1.3 to 1.4 times the base salary. For a Phoenix CISO at the $380K base figure, the fully-loaded annual cost crosses $500K and approaches $700K at the upper percentiles. That is a permanent salary line on the financial statements that does not flex with the business.
The next question is whether the business actually consumes a full FTE of CISO judgment. For most SMBs, the answer is no.
The fractional retainer market matured in 2025.
The Cynomi pricing guide, published in August 2025, captures the state of the vCISO market with specific numbers. Monthly retainers across the credible providers range from approximately $2,600 to $11,600. Cynomi puts the average full-time CISO cost at $300K annually and describes the typical fractional retainer as 30% to 70% less than the equivalent full-time engagement.
That range, $30,000 to $140,000 annually at the high end of the retainer market, overlaps with what midmarket organizations would pay an individual contributor security manager, while delivering the credential set and judgment of a CISO. The math works because the consultant amortizes their time across multiple clients. Each client gets the right slice of a senior practitioner rather than the wrong fraction of a full FTE.
The category has also stabilized in terms of what a fractional engagement actually looks like. The credible vCISO firms in 2025 are not delivering an hour of advice a month and calling it a CISO function. They are delivering a quarterly evidence pack, monthly advisory time, vendor risk reviews, board reporting, incident response coordination, and a defined SLA: the same set of artifacts a full-time CISO would produce, scaled to the cadence the business actually needs.
Where fractional wins decisively.
The math favors fractional clearly for organizations that meet three conditions:
- The business has a compliance forcing function but not enterprise scale. Cyber insurance renewal cycles, HIPAA Security Rule obligations, vendor questionnaires from enterprise customers: the work is real and recurring, but it does not consume a full FTE.
- The board, owner, or leadership wants quarterly visibility into security posture but does not need daily availability. A fractional engagement delivers the visibility on a defined cadence. A full-time hire delivers it constantly and you pay for the constant availability whether you use it or not.
- The organization's internal IT or MSP already handles operational work. The fractional CISO does not need to be a hands-on operator. The fractional CISO needs to be the senior judgment layer above the operator.
For the organization in this profile, fractional is not a discount. It is the right scale. A full-time hire would be over-buying capacity that the business cannot consume. The cost would be real; the additional value over fractional would not be.
ProactiveHQ's industry commentary on the rise of fractional engagement frames the talent-gap context: with approximately 4 million unfilled cybersecurity positions globally, the supply-side reality means even organizations with the budget for a full-time CISO often cannot find a qualified one to hire. The fractional model is not just a cost play. It is also the practical answer to a labor market in which the credentials matter and the credentials are scarce.
Where fractional doesn't win.
The case for hiring full-time is real and worth naming. The organization that should hire full-time is the one where:
- The regulatory environment requires a named, accountable C-suite security executive. Some financial services, healthcare, and federal contracting environments effectively require the role to be filled internally, not on retainer.
- The volume of decisions exceeds what a fractional engagement can support. Multi-thousand-employee organizations with active M&A, complex product portfolios, or geographic distribution typically consume more CISO capacity than any retainer model can deliver.
- The cyber risk exposure is so high that constant availability of senior judgment is part of the operational posture. Critical infrastructure, large healthcare systems, financial services with substantial trading operations: these organizations need the full FTE.
Outside those conditions, the full-time hire is often a credentials decision driven by what other companies of similar size have done historically, not a math decision driven by what the business actually consumes.
The decision is the consumption, not the credential.
The question to ask is not "should our company have a CISO?" but "how much CISO capacity does our business actually consume?" If the honest answer is somewhere between five hours a month and twenty hours a month, the fractional engagement is the right scale. If the honest answer is more than thirty hours a month and the business has the regulatory or operational profile to require constant availability, the full-time hire becomes defensible.
By Q4 2025, the market for fractional vCISO had matured enough that the right scale is reachable. The compensation data for full-time CISOs had grown enough that the cost of buying excess capacity was substantial. For most SMB and mid-market organizations, the math now favors paying for what the business consumes rather than what the org chart suggests it should have.
