🧪DATA LEAK PREVENTION

Multi-Tenant RLS Isolation Tester

A single misconfigured Supabase RLS policy exposed Client A's data to Client B. This prevents it.

The Problem

In multi-tenant SaaS, a single misconfigured Row Level Security (RLS) policy can expose one tenant's data to another. This is catastrophic — you lose all enterprise customers instantly, face GDPR/POPIA fines, and make national headlines. Most teams only discover this in production.

The Solution

An automated test suite for Supabase and Prisma that runs chaotic boundary injection tests in staging — intentionally trying every known RLS bypass technique to verify cross-tenant data isolation is mathematically impossible before deployment.

Why You Have No Choice

Gives tech leads a clean compliance log to hand to security auditors. Prevents the single most trust-destroying incident in B2B SaaS. No equivalent testing tool exists.

Code Preview

This is what you'll drop into your codebase. The full package includes all configuration options and integrations.

// rls-tester.config.ts
import { RLSTester } from './rls-tester'

const tester = new RLSTester({
  supabaseUrl: process.env.SUPABASE_URL!,
  serviceKey: process.env.SUPABASE_SERVICE_KEY!,
  tenants: ['tenant_a_id', 'tenant_b_id', 'tenant_c_id'],
  tables: ['documents', 'invoices', 'user_profiles'],
  attacks: ['tenant_escalation', 'null_rls', 'jwt_tampering'],
  outputReport: 'compliance-audit-log.json'  // hand to auditors
})

// Run in CI before every deploy
await tester.runAll()  // throws if any isolation failure found
