Zero trust
A security approach in which being inside the network grants no trust on its own and every access request is verified separately for identity, device and context.
- 01
Why it matters
The old approach trusted everything inside the office network; remote work, cloud services and hijacked accounts made that assumption invalid. Zero trust aims to keep an attacker who gets in confined to the narrowest permissions of the account they took over. It is not a single product but an architectural principle applied step by step.

Example
In one company, the accounting application can be reached only from company devices, with multi-factor authentication and only by accounting team accounts. A hijacked marketing account cannot reach it at all.
- 03
Common mistake
Thinking zero trust is a single product you can buy. Without an inventory of identities, devices and applications and simplified permissions, no product delivers the approach on its own.
