Multi-tenancy is the backbone of every scalable SaaS product, but getting it wrong leads to data leakage, performance bottlenecks, and compliance nightmares. We design and build multi-tenant architectures using row-level security, schema isolation, or database-per-tenant patterns -- choosing the right strategy based on your compliance requirements, scale targets, and cost constraints.

Secure, scalable tenant isolation patterns for SaaS products of any size
Database-enforced tenant isolation using PostgreSQL Row-Level Security policies that automatically filter every query by tenant context. Even if application code has a bug, the database layer prevents cross-tenant data access. Zero trust at the data layer with automatic policy enforcement on every SELECT, INSERT, UPDATE, and DELETE.
Dedicated database schemas per tenant for stronger isolation without the cost of separate databases. Each tenant gets their own tables, indexes, and migrations while sharing the same database instance. Ideal for B2B SaaS products that need compliance-grade isolation with moderate tenant counts.
Self-service tenant onboarding that automatically creates database schemas, configures storage buckets, provisions subdomains or custom domains, seeds default data, and sends welcome emails. New tenants are fully operational within seconds of signup with zero manual intervention.
Request-level tenant resolution from subdomain, custom domain, JWT claims, or API keys. The middleware injects tenant context into every request, ensuring all downstream database queries, cache lookups, file storage operations, and background jobs are automatically scoped to the correct tenant.
Platform-level analytics dashboards for SaaS operators that aggregate metrics across all tenants -- usage patterns, revenue per tenant, storage consumption, API call volumes, and feature adoption. Tenant-level dashboards for individual customers to track their own usage and billing.
Proven strategies for migrating between isolation models as you scale. Start with shared-database row-level security for cost efficiency, then migrate high-value enterprise tenants to dedicated schemas or databases. Horizontal sharding strategies for when a single database can no longer handle your tenant load.

Flexible engagement models for multi-tenant SaaS architecture
"We were terrified of a data leakage incident as we scaled past 200 tenants. Edesy implemented PostgreSQL row-level security policies that made cross-tenant access physically impossible at the database level. Our security audit passed with zero findings on tenant isolation -- a first for us."

"Tenant provisioning used to take our ops team 2-3 hours per customer. Edesy built an automated system that creates the schema, seeds data, configures the subdomain, and sends the welcome email -- all in under 10 seconds. We onboard 50+ tenants per week now without touching it."

"Edesy helped us migrate from a shared-everything architecture to schema-per-tenant for our enterprise customers while keeping the shared model for smaller accounts. The hybrid approach gave us compliance-grade isolation where needed without exploding our infrastructure costs."
