Phase 1: Security Assessment & Governance Blueprint (Weeks 1–2)

Centizen staffed cloud security architects and compliance analysts to assess the client’s AWS workloads and define a cloud governance model. This included IAM review, encryption policy mapping, and shared responsibility breakdown. A multi-cloud security posture management (CSPM) framework was initiated using tools like Prisma Cloud and AWS Security Hub.

Phase 2: Zero Trust Architecture & Identity Hardening (Weeks 3–4)

Centizen implemented a Zero Trust model, limiting access with strict IAM policies and multi-factor authentication (MFA). Critical workloads were segmented with security groups and network ACLs. AWS GuardDuty, Inspector, and Macie were integrated for threat detection and data classification.

Phase 3: Real-Time Monitoring & Threat Response (Weeks 5–6)

Cloud security engineers deployed a SIEM pipeline using Splunk Cloud integrated with CloudTrail, CloudWatch, and AWS Config. Real-time alerts were set up for suspicious activity, and auto-remediation scripts using AWS Lambda were configured for policy violations or drift.

Phase 4: Compliance Automation & Training (Weeks 7–8)

To meet compliance requirements (GDPR, SOC 2, HIPAA), Centizen automated audit logging, implemented encryption at rest and in transit (using AWS KMS), and applied CIS benchmarks. A security knowledge transfer and incident response training was delivered to internal DevOps and compliance teams.
