Harborline Health Systems

Regional healthcare software provider | 120 employees | AWS

Challenge

Harborline was running legacy on-premises infrastructure and needed to move to the cloud for compliance, scale, and multi-tenant SaaS delivery. They had manual infrastructure, inconsistent security practices, poor tenant isolation, and compliance audits that took months.

Pain: 4-week tenant provisioning process
Risk: Non-compliant data isolation between customers
Constraint: HIPAA and SOC 2 Type II mandatory

Solution

Ironleaf designed and implemented a multi-account AWS architecture with dedicated tenant accounts, automated provisioning, and encryption at rest and in transit.

✓ Multi-account landing zones (management, shared services, dedicated per-tenant)
✓ VPC automation with tenant-specific security groups
✓ Automated tenant provisioning via Terraform
✓ Comprehensive CloudTrail and Config logging
✓ SOC 2 Type II compliance automation

Outcomes

Observability Setup

Northstar Freight Network

Logistics technology platform | 85 employees | AWS

Challenge

Northstar's platform was experiencing frequent outages during peak load, alerting was noisy and unreliable, and the engineering team spent more time firefighting than shipping features.

Problem: 200+ daily alerts, 80% false positives
Impact: 15% incident-driven downtime annually
Cost: £180K+ per incident on freight operations

Solution

Ironleaf redesigned observability from the ground up: better metrics, centralized logging, distributed tracing, and SLO-driven alerting.

✓ Prometheus + Grafana for metrics and dashboards
✓ ELK stack for centralized logging
✓ Jaeger for distributed tracing
✓ SLO framework with smart alerting
✓ Incident response runbooks

Outcomes

82%

Reduction in false-positive alerts

58 min

Calder & Rowe Financial Services

Financial operations software | 200+ employees | AWS

Challenge

Calder & Rowe needed a multi-account AWS architecture that met strict financial compliance requirements (SOX), gave them cost visibility across departments, and enabled rapid infrastructure changes without security risk.

Requirement: SOX 404 compliance for all infrastructure changes
Pain: £2.8M annual cloud spend with poor cost visibility
Goal: Governed multi-account setup with department cost allocation

Solution

Ironleaf built a multi-account governance framework with automated compliance checking, cost allocation by department, and audit trails for all infrastructure changes.

✓ Control tower with SCPs and guardrails
✓ Department-specific accounts and cost centers
✓ Automated SOX compliance checks
✓ Change approval workflows
✓ Cost optimization and rightsizing

Outcomes

£2.1M
