Multi-account landing zone for a growing SaaS platform

Situation

Engineering teams were spinning up accounts and VPCs without shared identity, logging, or guardrails. Security reviews slowed every release, and production drift made incident response harder than it needed to be.

Approach

• Designed a multi-account topology with clear separation for shared services, non-prod, and production
• Established identity baselines, break-glass access, and centralized audit logging
• Applied network and tagging standards with policy guardrails before new workloads landed
• Documented runbooks and handover so internal teams could operate the foundation

Outcomes

• New environments follow a single governed pattern instead of one-off builds
• Security and platform reviews start from a shared baseline, not blank accounts
• Clear ownership of logging, networking, and access for ongoing operations

Outcomes are qualitative and anonymized. We do not publish fabricated metrics or named client endorsements here.
