Secure Architecture & Process Design
Design secure systems and workflows before development starts or major changes go live.
Design or challenge system architecture, sensitive workflows, vendor integrations, custody models, key ceremonies, signing policies, recovery procedures, operating controls, and go-live checkpoints before development, launch, or major change.
Discuss Architecture & Process DesignSecure Architecture & Process Design helps teams define, challenge, and improve security-critical systems and workflows before development starts or major changes go live. Guvenkaya designs and reviews the security architecture, trust boundaries, workflow, control model, runbook, and decision framework. The client, technology vendor, custody platform, or systems integrator owns configuration, code, deployment, and operation.
Best for
- • Architecture not finalized
- • System design needs security input before development
- • Sensitive data or privileged workflows need design
- • Vendor choice pending
- • Custody platform integration being planned
- • Key ceremony design or rehearsal needed
- • Custody, signing, approval, or recovery workflows need design
- • Tokenization or wallet infrastructure being designed
- • Existing architecture needs external challenge before major change
- • Development has not started or major changes are still being planned
Scope themes
- • System architecture and component boundaries
- • Data flows and sensitive-data handling
- • Authentication, authorization, and privileged-access models
