Supabase Security & Tenant Isolation Audit
Independent security assessment focused on protecting customer data in Supabase-based SaaS applications. We review authentication, authorization, Row Level Security (RLS), tenant isolation, service-role usage, API security, Edge Functions, storage access controls, and database permissions to identify paths that could expose sensitive information. The goal is to validate that security controls continue to enforce business boundaries correctly and prevent unauthorized access, cross-tenant data leaks, and privilege escalation as your application, team, and customer base grow.
01. Security Architecture Review
Understand how authentication, authorization, tenant isolation, API routes, service-role access, and trust boundaries are designed to protect customer data across the platform.
02. Authorization Review
Review Row Level Security policies, permissions, ownership checks, and access control rules to verify users can only access data and functionality they are authorized to use.
03. Technical Security Analysis
Perform manual code review and automated security scanning to identify vulnerabilities, misconfigurations, exposed secrets, insecure dependencies, and risky implementation patterns.
04. Tenant Isolation Validation
Execute practical security tests to confirm that users, organizations, and API consumers cannot access, modify, or infer data belonging to other tenants.
05. Security Findings
Deliver prioritized findings, supporting evidence, risk assessment, and actionable remediation recommendations to strengthen the application's long-term security posture.
