What is a fractional CISO or vCISO?

A fractional CISO, sometimes called a virtual CISO or vCISO, is an experienced chief information security officer who works with your company for a set portion of time instead of as a full-time employee. You get senior security leadership at a level that fits your stage.

When does a business need a fractional CISO?

Common moments include a customer asking for SOC 2 or a security review, cyber insurance requirements, handling sensitive data, adopting AI tools, or preparing for due diligence ahead of a raise or acquisition.

How is a fractional CISO different from a managed security provider?

A fractional CISO provides security leadership, strategy and accountability. A managed security provider runs day-to-day monitoring and tools. Many companies use both, and we can introduce trusted partners for each.

How is a fractional CISO engagement priced?

Most fractional CISOs work on a monthly retainer or a defined project fee, based on scope and time commitment. We help you define the scope first so the engagement fits your stage and budget.

Do you only work with San Diego companies?

No. Calqulate is based in San Diego and works with growing businesses and portfolio companies nationwide.
