- A new product, major feature, integration, or architectural change is still early enough to influence.
- Authentication, authorization, APIs, tenant isolation, sensitive data, or service-to-service trust are material to the design.
- The team wants to avoid discovering expensive design risk after implementation or production launch.

Indicative USD baseline for a clearly bounded scope.
Typical delivery3–10 business days
Calendar timing depends on access, evidence, target size, and stakeholder availability.
Commercial modelFixed scope
Scope, assumptions, deliverables, timeline, and price are confirmed before delivery begins.
Baseline scopeOne bounded system, major feature, API platform, or architecture change with trust boundaries, abuse paths, and design controls.
No surprise hourly overages on agreed packaged work. If the scope changes materially, additional work is agreed in writing before it starts.
When this service fits
Recognize the decision before choosing the scope.
01
Where are the important trust boundaries, abuse paths, and attack assumptions?
02
Which threat scenarios are material enough to change the design or controls?
What we review
Focused on the controls that change real product risk.
The exact evidence set is tailored during discovery. A typical engagement covers the areas below.
- System context, data flows, assets, and trust boundaries
- Authentication, authorization, and tenant isolation
- API and service-to-service security
- Secrets, encryption, key management, and sensitive data flows
- Cloud, container, and Kubernetes security assumptions
- Abuse cases, attack paths, compensating controls, and residual risk

Engagement shape
Clear scope. Evidence. Priorities. Remediation.
01Discover
Goals, environment, constraints, evidence, and success criteria.
02Review
Technical and process assessment with targeted automation where useful.
03Prioritize
Risk, attack paths, engineering effort, and business context.
04Enable
Report, roadmap, workshop, and optional remediation validation.
Typical engagement: 3–10 business days for a bounded system or major feature.
Client side of the engagement
Know what changes, what is needed, and what can follow.
What changes after
- Architecture decisions are backed by an explicit threat model and prioritized risk register.
- Engineering receives concrete secure-by-design guardrails instead of abstract recommendations.
What we need from you
- Current architecture diagrams, data flows, trust relationships, and deployment context.
- The authentication/authorization and identity model, including important third-party integrations.
