# Zero-Trust Security

> **Definition:** Zero-Trust is a cybersecurity framework based on the premise that no user, device, or system should be trusted by default, whether inside or outside the organization's network perimeter.

## In depth

Traditional security models focused on protecting the network perimeter. Once inside, users had wide access. Zero-Trust requires continuous validation at every step: validating device health, verifying identity via MFA, and enforcing least-privilege permissions. All traffic is encrypted end-to-end.

## How ERPStack applies this

We design all custom systems with Zero-Trust principles, enforcing VPC network isolation, row-level database controls, and time-bound API session tokens.
