Fractional CISO
Secure your growing business
Without full-time CISO
vCISO (virtual Chief Information Security Officer) is a cybersecurity service model that delivers the expertise and leadership of a Chief Information Security Officer on a flexible, outsourced, or fractional basis.
A vCISO helps organizations by:
‣ Identify and prioritize risk with business-aligned assessments tailored to your industry and growth stage.
‣ Build and execute cybersecurity strategies that drive resilience, compliance, and competitive advantage.
‣ Lead security initiatives with hands-on oversight of your people, processes, and technology stack.
‣ Provide technical assistance including architecture review, core review, security testing, and configuration of security solutions.
‣ Make faster, smarter decisions with executive-level guidance and access to proven frameworks.
‣ Support board and investor confidence with reporting that translates risk into business language.
