Selected Engagements
Tier 1 Financial Market Infrastructure
Target operating model & agentic AI transformation roadmap

Engaged to redesign the security operating model for a Tier 1 global exchange group, running a privileged access management uplift in parallel and building the target operating model and delivery roadmap for the organisation's first agentic AI deployments.

High-Growth SaaS
Rebuilding a security function inherited from tooling-led delivery

Took over as fractional CISO from a tooling-led buildout that had deployed security products without the operational maturity to run them. Stood up SOC coverage, DLP, a risk management and GRC programme, control assurance, and a board-level cyber strategy from the ground up.

Enterprise SaaS Platform
FedRAMP Rev5 & 20x readiness

Leading a fast-scaling SaaS platform through FedRAMP Rev5 authorisation to submission milestone, while standing up SOC coverage, vulnerability management, a GRC programme, and continuous monitoring (ConMon) to meet FedRAMP 20x readiness requirements.

Tier 1 Global Bank
Strategy and investment portfolio at global scale

Designed and executed the cybersecurity strategy and investment roadmap for a Tier 1 global bank, holding accountability for a £160–240M portfolio across 50+ countries while embedding a leaner, more efficient operating model.

How We Work

Three ways security transformation gets delivered. Only one keeps the person who built the trust accountable for the outcome.

The Big Four Model

A senior partner sells the vision. Once the SOW is signed, delivery passes to graduates and junior consultants. The cost stays senior-level. The delivery doesn't.

The Staffing Model

Reliable delivery resource against a defined scope. No strategic ownership, no governance, no one accountable for whether the engagement actually moves the needle.

Our Model

The senior leader who builds the credibility stays engaged for the life of the engagement — owning governance and outcomes — while directing a vetted bench of architects, engineers, project managers, and analysts against the plan.

Why Us

Board-level security expertise, without the full-time price tag.

CISO Advisory Group delivers senior cybersecurity leadership to organisations that need it most — whether you are scaling rapidly, navigating a complex regulatory landscape, or simply lack the internal capability to stay ahead of the threat.

Our principal has spent over two decades leading security at the highest levels of global finance and critical national infrastructure. That depth of experience is what we bring to every engagement, applied practically to your environment, your risks, and your business objectives.

We are not a consultancy that produces reports and moves on. We embed, we own outcomes, and we stay until the job is done.

Beyond direct engagements, our principal has presented original research on AI security and post-quantum readiness directly to Tier 1 financial institution leadership teams, and has delivered executive and practitioner training across IAM, PAM, GRC, AI security, and post-quantum readiness.
