OUR DEVELOPMENT STANDARD

Built Under a Secure SDLC & Code Quality Framework

Every solution RannLab delivers is developed under a rigorous Secure Software Development Lifecycle (SDLC) — with mandatory code quality gates, AI code governance, security reviews at every phase, and zero-tolerance policies for critical vulnerabilities. This is not a checklist — it is the standard by which all our software is built.

Security at Every Phase

Threat modelling, SAST/DAST scanning, and security reviews built into every sprint.

Quality Gate Enforcement

Automated quality gates block deployments that fail coverage, complexity, or duplication thresholds.

AI Code Governance

All AI-assisted code is reviewed, tested, and validated before it enters the codebase.

CI/CD & Audit Trails

Every change is tracked, reviewed, and deployed through automated, auditable pipelines.
