What we do

Cyber security architecture services

Walnut Partnership helps you design, modernise and assure the security of the systems that matter most – especially where regulatory, audit and availability pressures are high.

🧭

Security & solution architecture

Target and current-state security architectures for critical business services. We map data, access and control points, then design pragmatic improvements that work with your existing platforms, people and risk appetite.

Ideal when: you’re changing core systems
🛡️

Detection & response design

Architecture for endpoint detection and response (EDR), antivirus, logging, SIEM and threat/vulnerability management. We focus on signal quality, coverage of critical assets and realistic operating models.

Ideal when: tooling exists but coverage doesn’t
✔️

Risk, audit & remediation support

Turning security findings into workable solutions. We help you interpret assessments, design remediation paths and sequence change so that risk reduces without breaking day-to-day operations.

Ideal when: reports outpace fixes
