This is the fifth and final article in our series about managing a fractional CISO relationship. Check out our profile for the other articles covering the lifecycle of the relationship.
Fractional CISOs are an excellent way for growing companies to access senior security leadership early. But as the business evolves, the model may stop being the right match.

Three Transition Paths That Fit Different Stages of Growth
