Security Architecture & Research
I design, prototype and test security architecture, so you know it works before you rely on it.
- Threat modelling & design review
- Reference architectures & prototypes
- Technology & vendor evaluation
Technical advisory for security teams
Security architecture and detection engineering.
Technical leadership across security architecture, threat detection and applied research. I design solutions, build them and prove they work.

Help at the depth you need
I deliver practical outcomes and prove them in your own environment.
ProjectDefined scopeWe agree scope, deliverable and timeline.
EmbeddedTechnical leadershipI embed with your team, or lead it.
Advisory hoursTechnical sounding boardSenior technical input as decisions come up.
Threat Detection & Response Engineering
I build detection around how real adversaries operate, and validate it by testing, not by assuming it works.
- Detection engineering & coverage mapping
- Purple-team validation & tuning
- Logging strategy & incident readiness
Infrastructure & Systems Architecture
I design architecture grounded in years of running production infrastructure.
- Architecture, identity & hardening
- Automation & platform builds
- Technical team leadership
Approach
From problem to working solution
Understand
I learn your environment, threats and constraints first-hand, not from a slide deck.
Design
I architect a solution that fits your team, your stack and your real risks.
Build
I prototype, implement and integrate alongside your engineers.
Prove
I test it against real adversary behaviour and hand over something that works.
About
Still building.
Tim Vivian
I’m a Principal Architect who still builds. I started in infrastructure, moved through security programs and adversary emulation, and now lead threat detection, research and architecture for the teams I work with.
That background means I design defences by thinking like an attacker, and I can review an architecture or write the detection for it.
