Zero Trust
Definition
Zero Trust verifies every access instead of trusting devices or people solely based on their network location.
A security model without implicit trust due to network location; every access is risk-based authenticated, authorized, and continuously evaluated.
Simply explained
Even within the corporate network: anyone who wants to access something must be verified and authorized for it.
Why it matters in practice
The term contributes to secure, maintainable, and high-performance web applications as well as resilient technical decisions.
Example from business
An operation verifies identity, device status, and resource at every internal application access.
Limits and pitfalls
- Zero Trust is not a product; ZTNA is only an access solution within possible architectures and does not replace data or application security.
Origin & history
NIST SP 800-207 systematized Zero Trust Architecture for modern enterprise environments in 2020.
Use in mid-sized companies
- Possible example: An operation verifies identity, device status, and resource at every internal application access.
