Zero Trust

Zero trust is a security architecture that eliminates implicit trust, requiring continuous verification of every user, device, and network flow regardless of location. The principle "never trust, always verify" replaces traditional perimeter-based security models. Zero trust implementations enforce least-privilege access, micro-segmentation, multi-factor authentication, and continuous monitoring. Every request is authenticated and authorized independently, even from within the corporate network. For URL shortening services, zero trust principles apply to both infrastructure security and link access control. Administrative APIs require strong authentication per request. Private short links verify user identity before redirecting. Internal services communicate through authenticated channels. This prevents lateral movement if any single component is compromised.
