9. Real-World Case Studies
Financial Services: SDLC Compliance Transformation
Issue: Fragmented DevSecOps practices and lack of traceability across pipelines.
Impact: Failing compliance audits and repeated vulnerabilities in releases.
Our Role: Implemented secure SDLC framework, introduced automated SAST/DAST, trained developers.
Outcome: 60% reduction in security bug backlog; passed SOC 2 & ISO audits.
SaaS Platform: CI/CD Security Integration
Client: VC-funded B2B SaaS company
Findings: No security gates in CI/CD, hardcoded secrets in codebase.
Outcome: Integrated SAST/SCA/Secrets Detection, enforced secrets policy, adopted OWASP SAMM KPIs.
