Enterprise Security Audit for E-commerce Platform
Comprehensive OWASP-based audit of a large-scale e-commerce system — delivering full visibility, risk mitigation, and a strategic roadmap for DevSecOps maturity.Client & Project Overview
A leading e-commerce enterprise partnered with SiriusOne to perform a full-cycle security audit across applications, infrastructure, and cloud environments. The goal was to validate every layer of protection — from source code to AWS configuration — ensuring compliance with OWASP, CIS, and Secure SDLC principles.
Business Problem
As the platform scaled to millions of users, its growing complexity increased the risk of undetected vulnerabilities. Ad-hoc checks were no longer enough — the company needed an independent, structured assessment that provided measurable, lasting results. The client required:
- Verification of application security and coding standards
- Validation of CI/CD and secrets management practices
- Cloud and WAF configuration review
- Full dependency and license analysis
- A long-term roadmap for continuous DevSecOps improvement
"Our approach was to turn security from a reactive process into a predictable system. We combined automation with deep manual analysis — not just to find issues, but to strengthen every link between development and security."

Solution Overview
SiriusOne applied a hybrid audit model combining automation precision with manual expertise. The audit framework ensured technical depth while aligning security results with business priorities.
Comprehensive Source Code Review
Manual and automated analysis across all apps revealed logic, authentication, and performance flaws.
Cloud Security & WAF Validation
CSPM review and WAF tuning confirmed resilience against OWASP Top 10 vulnerabilities.
CI/CD and Secret Management Inspection
Audited pipelines for credential safety and compliance with best DevSecOps practices.
Dependency & License Audit
Generated full SBOM, scanned open-source components, and verified licensing compliance.
OWASP SAMM Maturity Assessment
Mapped current security maturity and delivered a 3–6-month roadmap for continuous improvement.
Results
Unified security posture across all layers
The audit delivered a single governed model aligning application code, cloud infrastructure, and CI/CD pipelines. This provided the client with a unified view of their security posture, replacing fragmented oversight with a cohesive, transparent management strategy.
Full remediation of critical infrastructure gaps
Critical vulnerabilities were identified and remediated across both application and infrastructure layers, including deep-seated gaps missed by previous scans. AWS and WAF configurations were optimized to provide robust protection against OWASP Top 10 threats.
Hardened CI/CD and Supply-Chain governance
CI/CD pipelines were secured by eliminating exposed secrets and embedding security controls into workflows. Combined with an SBOM-based approach for open-source dependencies, this ensured full license compliance and control over supply-chain risks.
Sustainable security culture and 6-month roadmap
The engagement shifted security from a one-time audit to a repeatable, measurable process. With a clear 3–6 month DevSecOps roadmap, security is now a core part of the product culture, ensuring long-term alignment with business priorities.
