Zero trust network architecture, or zero trust network access (ZTNA) is a network security design methodology. It states that users and devices are inherently untrusted no matter where they are located. This contrasts with a traditional model, where devices connected to the local network are largely considered safe, and authorized to access most other resources on the same network.

The increase in remote work and the use of cloud applications has posed new security challenges for businesses. The traditional model, where employees use virtual private networks (VPNs) to access company resources remotely, opens companies up to several security risks.

Companies are increasingly turning to ZTNA solution providers, like Perimeter 81, to better secure their digital assets. IT professionals knowledgeable of ZTNA practices are in high demand, so we’ve listed 10 of the best ZTNA online courses you can use to get up to speed with this important technology.
