Every organisation needs security leadership but not every organisation needs a permanent, full-time resourced CISO. For many, the challenge is balancing the need for executive-level expertise with the realities of budget and scale.

Parabellum’s vCISO & CISO-as-a-Service offering bridges that gap. Our consultants bring decades of senior cyber leadership experience, advising governments, regulators, and enterprise organisations. Acting as an extension of your executive team, we design strategies, oversee governance, and provide board-ready assurance tailored to your risk appetite and industry requirements.

Unlike short-term consultancy, our retainer model ensures continuous alignment and improvement. Your CISO partner is available on an ongoing basis to maintain your ISMS, support risk committees, advise on emerging threats, and guide compliance with frameworks including ISO/IEC 27001 and 27005, the NIST Cybersecurity Framework, NIST SP 800-30/53, CIS Critical Security Controls, SOC 2 Type II, the ASCS Essential Eight, and APRA CPS 230/234.

The result is lasting assurance: strategic leadership that evolves with your business and a trusted partner who strengthens resilience every day.
