Zero Trust Security

Zero Trust Security is a security model that does not trust any user, device or service by default. Instead, every access is continuously verified and evaluated on the basis of identity, context, risk and permission. The well-known guiding principle is: never trust implicitly, always verify. For organizations, zero trust is relevant above all because classic network perimeters have lost importance through cloud usage, remote work and SaaS.

A zero trust approach typically includes strong identity controls, least privilege, device health checks and segmented access models. It is important to understand zero trust not as a single product but as an architectural and operating principle. In practice, implementation is usually gradual and follows concrete protection needs. Applied correctly, zero trust reduces the attack surface and makes lateral movement by attackers considerably more difficult. An important foundation for this is Identity Security, because identities and permissions frequently form the entry point for attacks; Zero Trust solutions provide the architectural framework.
