SaaS security & RLS audit
Multi-tenant SaaS teams who want certainty before enterprise deals or audits that no tenant data leaks.
Updated: 2026-07
A SaaS security audit targets tenant isolation specifically: is row-level security watertight, does access control hold, are typical Supabase pitfalls (service role in the client, missing RLS) avoided? The output is a finding with concrete fixes.
The most common critical gap in multi-tenant SaaS is not an exotic zero-day but flawed tenant isolation: an RLS policy that does not apply, a service-role key in the browser, a table without row-level security enabled. At worst, one customer sees another’s data.
A targeted audit finds exactly this class of error — from people who run multi-tenant SaaS on this stack and know the pitfalls from practice.
