Architecture security assessment

At a glance

Context / challenge

A HealthTech (or multi-tenant SaaS) team wanted security input while major design decisions were still movable: data partitioning, identity model, integration boundaries and logging. The goal was to catch structural issues before a late-stage pentest could only report them as expensive rework.

This sits under security assessments / architecture review within Solutions, often paired later with web, API or cloud testing.

Engagement shape

Typical shape: workshop-led review of architecture diagrams, data-flow descriptions and control intent; threat scenarios aligned to the sector (e.g. sensitive health data, tenant isolation, third-party integrations); written findings as design risks with recommended control patterns — not exploit payloads.

Approach

Finding classes (illustrative)

Illustrative design-risk classes: unclear tenant or patient-data binding; over-trust of internal networks; third-party integrations without abuse cases; secrets and key management gaps; missing abuse-case logging; environments that collapse prod-like controls in staging.

Outcomes and remediation pattern

Architecture owners leave with prioritised design changes, a clearer control map, and a backlog that later pentests can verify. We do not invent compliance certification claims; if a framework is in scope we map control intent honestly.

Lessons for buyers

• Buy architecture review early when isolation and data-flow decisions are still cheap to change.
• Ask for abuse cases, not only component inventories.
• Plan a later build-time pentest to verify the design landed.
• Keep public case studies anonymised — diagrams in the private report stay under NDA.
