A government-affiliated agency partnered with Intarmour to migrate its core systems to AWS—embedding compliance by design, eliminating fragility, and gaining real-time control over infrastructure and risk.
The Mission
The agency operated critical digital services at national level. Its infrastructure—spread across fragmented, aging on-prem systems—was increasingly unstable, expensive, and vulnerable to cyber risk.
The goal: migrate to AWS within six months with zero service disruption, full regulatory alignment, and scalable architecture that could adapt under pressure.
Downtime, audit gaps, and data exposure were not acceptable. The transformation had to deliver speed, traceability, and resilience—simultaneously.
The Approach
A secure migration designed from the inside out
Rather than “lifting and shifting” systems into the cloud, we began with a structured discovery and scoring phase—mapping:
Application criticality to daily operations
Regulatory sensitivity of hosted data
Required controls for identity, encryption, and audit
This analysis led to a migration blueprint that followed the AWS Well-Architected Framework, but was adapted for a regulated public environment, where scrutiny and risk surface are higher.
Key priorities included:
Least-privilege IAM from day one
Environment isolation via a multi-account strategy
Encrypted-by-default workloads
Compliance artifacts baked into every deployment
The Implementation
Infrastructure as Code meets security by default
We built everything using Terraform and peer-reviewed workflows—ensuring every deployment was documented, auditable, and version-controlled.
Security wasn’t added after the fact. It was the foundation.
IAM roles were scoped with surgical precision
Encryption at rest and in transit was enforced across all data flows
CloudTrail, AWS Config, and centralized logging captured every change
Guardrails and Service Control Policies ensured nothing fell through the cracks
Threat modeling was performed on high-sensitivity apps, and guardrails protected against misconfiguration drift in production.
Compliance Layer
Mapped and aligned before the first deployment
From the start, we aligned each workload with compliance controls from:
NIS2 Directive (essential service operators)
GDPR (personal data flows and auditability)
National cybersecurity guidelines from CERTs and supervisory agencies
Automated audit evidence was generated by design—not manually after the fact. Deployment pipelines produced logs, change records, and policy confirmations, ready for inspection.
Dashboards gave the agency real-time visibility into infrastructure health, configuration drift, and control coverage.
The Outcome
Migration completed. Control gained. Risk reduced.
After 5.5 months:
The agency achieved 99.99% uptime across migrated systems
Infrastructure costs fell by 28%
Security audits revealed zero critical findings
Patch cycles and incident response times improved measurably
Internal teams gained confidence and clarity, not just performance
Most importantly, compliance wasn’t a constraint—it became an enabler.
The agency now treats its AWS environment as a strategic asset, not just a backend.
Need to migrate to AWS without losing control or failing compliance audits?
Let’s build secure, scalable, inspection-ready infrastructure—together.
