Overview
We architected a unified zero-trust security model for a SaaS provider operating across AWS and Azure. Reduced their attack surface by 70%.
The Challenge
A fast-growing global SaaS provider experienced rapid scaling, leading to a fragmented multi-cloud environment split across AWS and Microsoft Azure. Their infrastructure had become a complex web of misconfigured IAM roles, public-facing S3 buckets, and overly permissive firewall rules. They required a unified, robust architecture to protect sensitive client data and achieve SOC2 Type II compliance.
Our Approach: Zero-Trust Cloud Architecture
HackVitraSec conducted a comprehensive Cloud Security Posture Management (CSPM) review and manual infrastructure audit. Our strategy focused on implementing a strict Zero-Trust model:
- IAM Hardening: Audited over 500+ IAM roles and policies, enforcing the Principle of Least Privilege (PoLP).
- Network Segmentation: Redesigned VPCs and subnets, isolating the database tier from the public-facing application tier using stringent Network ACLs and Security Groups.
- Secret Management: Migrated hardcoded credentials from environment variables to AWS Secrets Manager and Azure Key Vault.
- Continuous Monitoring: Integrated AWS CloudTrail and Azure Monitor logs into a centralized SIEM for real-time anomaly detection.
The Solution & Impact
We delivered an Infrastructure as Code (IaC) security blueprint using Terraform to ensure all future deployments adhered to the new security baseline automatically.
Results:
- Reduced the external attack surface by 70% within the first month.
- Successfully passed the SOC2 Type II audit with zero major non-conformities.
- Automated security compliance checks within their CI/CD pipeline, ensuring secure cloud deployments.
