Technical Deep Dive

For a SaaS business, a customer data leak is the ultimate failure. Whether you're building on Supabase, AWS, or your own hardware, your multi-tenant isolation logic must be flawless. DBX provides a 'Database X-Ray' specifically for SaaS builders, tracing every logical relationship and security policy to ensure that data from 'Tenant A' can never, under any circumstances, be reached by 'Tenant B'.
