At some point, security stops being something your lead engineer handles on the side and becomes a real function that needs an owner. When you reach that point, you face a choice: hire a full-time Chief Information Security Officer, or bring in a fractional one. This post compares the two models on cost, coverage, and fit, so you can tell which your company actually needs right now.
The Core Difference
A full-time CISO is an executive on your payroll who owns security as their entire job. A fractional CISO, often called a virtual CISO, does the same job on a part-time retainer, usually split across several client companies. Both set strategy, own compliance, manage risk, and report to leadership. What changes is how much of their time you get and what you pay for it.
What a Full-Time CISO Gives You
A full-time hire brings dedicated attention, deep single-company focus over time, and a senior leader who can build and manage an internal security team. For a company with a large attack surface, a growing security team to lead, or security decisions coming up every day, that focus is worth the cost. The tradeoff is that same cost, plus the risk of hiring a senior executive before your security needs justify one.
What a Fractional CISO Gives You
A fractional CISO gives you senior, CISSP-certified leadership without a full-time salary, experience drawn from many client environments rather than one, and coverage that scales up during an audit push and back down afterward. You get the strategy, compliance leadership, and risk oversight of a CISO, sized to what your stage requires. For a fuller breakdown of the role, see what a vCISO is and when to hire one.
The Cost Comparison
A full-time CISO in the United States costs roughly $200,000 to $400,000 a year once you include salary, equity, benefits, and bonus. A fractional engagement is a monthly retainer, commonly $3,000 to $12,000 depending on scope, which works out to 50 to 75 percent less over a year.

When a Full-Time CISO Makes Sense
Bring on a full-time CISO when you have a security team that needs a full-time leader, when security decisions come up daily and cannot wait for a scheduled call, when you are large or regulated enough that a dedicated executive is clearly justified, and when the budget can absorb the total compensation without holding back other critical hires.
When a Fractional CISO Makes Sense
A fractional CISO fits when you need security leadership but not forty hours a week of it, when you are pursuing SOC 2, HIPAA, or ISO 27001 and want someone who has done it before, when enterprise prospects are asking who owns security and you need a credible answer, and when you want senior expertise now without a months-long executive search.
How to Decide
Ask yourself three questions. How many hours of security leadership do you genuinely need each month? Do you have an internal security team that requires a full-time manager? Can the budget support $250,000 or more in total compensation without slowing your other hiring?
If you need fewer than full-time hours, have no team to manage yet, and would feel the weight of a full-time executive salary, a fractional CISO is almost certainly the better starting point. Plenty of companies run fractional for a year or two, then move to a full-time hire once the security function grows into the role.
