Vaultify: multi-tenant SaaS production hardening

System

Vaultify is a production SaaS operating on Supabase/PostgreSQL, TypeScript and Vercel, with tenant-isolated business workflows.

Production risk addressed

The database security boundary required hardening so privileged execution could not remain exposed to public API roles.

Work completed

• Removed privileged database execution from anonymous and authenticated roles.
• Restricted privileged execution to service-role boundaries.
• Applied explicit least-privilege grants for backend services.
• Added CI security regression checks to prevent the exposure from returning.
• Verified production deployment after hardening.

Current production surface

The system includes CRM/leads, quotes and digital acceptance, recovery workflows, billing/entitlements, incidents/health, integration health and cost tracking.
