A templated, governed multi-account AWS foundation
Onboarding new client environments meant rebuilding account structure and governance from scratch each time, with no consistent isolation model. We built a templated foundation that made every new environment consistent from day one.
Every new tenant environment built the same governed way.
Complete isolation between client environments.
Central governance with consolidated billing.
The challenge
Every new environment, rebuilt from scratch
Onboarding new client environments meant rebuilding account structure and governance from scratch each time, with no consistent isolation model between tenants — slow to stand up and inconsistent once live.
Before
- Account structure rebuilt manually per client
- No consistent tenant isolation model
- Governance applied inconsistently across environments
- Billing scattered across accounts
After
- Templated, governed multi-account foundation
- Complete tenant isolation by design
- Central governance applied consistently
- Consolidated billing across the estate
How we approached it
Govern centrally, automate the guardrails, vend accounts repeatably
Govern from the centre
We implemented centralised account management with AWS Organizations, Service Control Policies, and consolidated billing — so every linked account inherits the same guardrails and rolls up into one bill.
Make security the default
We automated the creation of security groups, cross-account records, EBS encryption, and S3 public-access controls, with VPC and subnet setup driven by IP-range specification — and layered on MFA, password policies, and IAM roles.
Deploy consistently
We built automated GitLab CI/CD pipelines so resources deploy and are monitored the same way across every account — giving DevOps teams speed without giving up control.
Under the hood
Next step
Rebuilding account structure and governance for every new client?
We template the foundation once, so every new environment inherits governance and isolation by default.
