How does PostgreSQL Row-Level Security (RLS) prevent cross-tenant data leaks?

RLS enforces tenant_id checks directly inside the database engine using the authenticated session context, ensuring a query can never return another organization's rows.

Can each enterprise client use their own Identity Provider (Okta/Entra ID) in a multi-tenant portal?

Yes. Edge middleware inspects the email domain or custom hostname and routes the user to that specific organization's SAML 2.0 or OIDC identity provider.

How is this implemented across Vezert B2B web projects?

Every €1,500 landing page, €4,500 corporate website, and €9,000+ web portal we deliver includes full technical validation, 5-locale parity, and 95+ Core Web Vitals.
