Information Security Consultant

About the role

Zensec provides virtual CISO (v CISO) and information security consultancy services to organisations across the Channel Islands and beyond.

Our clients rely on us to own the parts of their security programme they cannot resource internally — from regulatory compliance and risk management through to board-level reporting and incident readiness.

As an Information Security Consultant you will act as the v CISO lead on a portfolio of client engagements.

You will be the security voice in the room: setting direction, running the compliance and assurance cycle, presenting to boards, and building long‑term relationships with client stakeholders.

This is a client‑facing consultancy role that combines hands‑on technical assurance with strategic advisory work.

You will also help shape how Zensec delivers its services — improving methodologies, mentoring junior consultants, and contributing to scoping and proposal work.
