Core offerings

I support tech teams and mission-led organisations with strategic security, scenario-driven facilitation, and grounded resilience-building. My work blends systems thinking with deep technical insight, favouring practical outcomes over theatre.

Area What I do Who benefits
Threat modelling Guided sessions to map attacker goals, identify weak spots, and design proportionate defences. Risk first, tooling second. Founders, architects
Labs & workshops Drills, red/blue roleplay, and real-world scenarios that build confidence in security incident handling and response planning. Developers, ops teams
Facilitation From retrospective sessions to strategic offsites and scenario planning, I help teams think clearly and adapt without panic. Leadership & scaling teams
Digital safety Security that fits smaller orgs: low-cost deployments, plain-language training, and human-centred risk reduction strategies. Founders, volunteers, advocates

Focus areas

Threat modelling & risk-driven architecture

I help teams think like attackers — then act like adults. Through collaborative modelling sessions, I support critical decisions around architecture, trade-offs, and defensive priorities. Minimal jargon. No AI panics. No Big Tech overkill.

Hands-on security labs & workshops

I design training that sticks. This includes role-based exercises, attack simulations, and decision drills that reveal blind spots and test assumptions. Sessions are always tailored — never off-the-shelf — and support teams at any stage.

Organisational resilience & facilitation

Using methods grounded in systems thinking and Satir-based development, I work with leadership to navigate complexity, improve decision-making, and sustain healthy, adaptable structures. This includes retrospectives, strategy support, and future-scenario planning.

Digital safety for grassroots and nonprofits

Security support should be accessible, not extractive. I build practical, long-term solutions for advocacy networks, shelters, and volunteer teams. This includes private SIEM setups, safer communication strategies, and support for projects like:

Approach

My work is grounded, iterative, and focused on what actually helps people make better security decisions. Whether the challenge is technical, organisational, or behavioural — I’ll help you ask sharper questions, design clearer responses, and avoid the usual hype.
