Frequently asked questions
When does it make sense to hire a Fractional CTO for Cybersecurity?
Typically when Cybersecurity has become a strategic priority — a board has asked for assurance, a customer or investor is pressing on the area, or the existing team has hit the limits of in-house expertise — but the work doesn't yet warrant a full-time senior hire. A fractional engagement gives senior coverage of the area while the longer-term shape of the team is being worked out.
How is a Fractional CTO different from hiring a Cybersecurity consultancy?
A consultancy typically delivers a project against a brief; a fractional CTO works inside your leadership team, owns the area, and is accountable for outcomes across multiple workstreams. They can also engage and manage specialist consultancies when delivery capacity is needed beyond what a single leader can provide.
Do the Fractional CTOs in this directory have hands-on Cybersecurity delivery experience?
Yes. The directory only lists CTOs with senior delivery experience in the specialism areas they tag. Each profile includes a bio, regions covered, and industry experience so you can shortlist candidates whose hands-on background matches your context.
