Cloud Security & Identity Architecture

Challenge

Broad access paths had accumulated across a large AWS estate. Identity was a set of one-off accounts, not platform infrastructure, so production boundaries were unclear and hard to change safely.

Decision

Put identity boundaries in the same Infrastructure as Code as the rest of the platform. Access changes would go through automation — not a separate security process bolted on afterward.

Approach

The approach treated identity, access controls, and automation as one problem, so security patterns lived next to networking and compute instead of beside them.

Technical Delivery

Implemented identity architecture, access controls, and cloud-security patterns in the platform automation. After the work, fewer standing access paths remained, and changes to who could reach production went through the same reviewable infrastructure as everything else.

Outcome

Unnecessary access paths were reduced and identity boundaries made explicit, with security patterns living in the same infrastructure code as the rest of the platform.
