AWS Account Remediation

Computacenter’s Serverless AWS Account Remediation service automates the discovery, remediation and governed migration of AWS resources across accounts and organisations using a fully AWS-native framework. Built on AWS Step Functions, Lambda, Amazon S3, AWS KMS, IAM Identity Center, AWS Config, Security Hub, GuardDuty and CloudTrail, the service eliminates shared accounts, enforces least-privilege identity controls, and generates validated Terraform Infrastructure-as-Code configurations for every remediated resource. Customers benefit from zero-downtime migration, full IaC coverage and an active compliance baseline from cutover.

Dedicated state machines per resource type — EC2, RDS, S3, Lambda and IAM — execute an inspect, encrypt, share and generate sequence, surfacing Terraform templates to application teams for validation before deployment via AWS CodeBuild or existing CI/CD pipelines such as GitHub Actions and GitLab CI.

The service addresses common enterprise challenges including fragmented multi-account estates from mergers and acquisitions, over-privileged IAM configurations without MFA, manually provisioned resources with no version-controlled baseline, and compliance gaps under ISO 27001, SOC 2, DORA, FCA, FDA 21 CFR Part 11 and UK Cabinet Office secure-by-design requirements. Computacenter delivers account consolidation, divestiture separation, IAM remediation and Landing Zone modernisation through a structured five-phase engagement: Discovery, Design, Identity and Security Remediation, Resource Remediation and IaC Baseline, and Hypercare and Handover. Each phase includes formal deliverables, signed acceptance criteria and a complete audit evidence pack including CloudTrail logs, AWS Config snapshots and Security Hub compliance reporting.

Validated at enterprise scale, including the remediation of 18 shared accounts and over 269,000 resources for a global organisation with zero downtime, the service is applicable across financial services, life sciences, UK public sector, retail and manufacturing. Delivered by our AWS SME's, the engagement provides a 30/60/90-day cloud maturity roadmap, a reusable Terraform module library, and knowledge transfer across Identity Center, Security Hub and AWS Config, ensuring customers can operate, govern and evolve their environment independently from day one.
