Key Security Attributes of a Zero Client:

1. Locked BIOS Firmware:
   A zero client operates using firmware embedded in a locked BIOS, rather than a traditional, accessible operating system.
   • This design restricts the device to a single connection point.
   • With firmware contained in the locked BIOS, the device cannot be rooted, hacked, or redirected, even through a reboot.
2. No Accessible Storage:
   • Zero clients have no user-accessible storage.
   • Powering off the device erases all session memory, ensuring nothing is retained between uses.
3. No Data Leaves the Data Center:
   • During use, only encrypted pixels are transmitted between the centralized, secured computer and the zero client.
   • No actual data is transferred or stored on the device itself.

These attributes ensure that:

• A zero client cannot be redirected from its assigned endpoint.
• If stolen, the device becomes inaccessible and unusable.
• Data transmissions are never stored locally, preventing interception during use.

Benefits Beyond Security

In addition to strong security, zero clients are:

• Exceptionally reliable
• Long-lasting
• Simple for IT to manage and deploy

Compatibility & Use Cases

Zero clients are compatible with:

• PCoIP
• VMware
• Amazon Web Services (AWS)

This makes them ideal for establishing secure connections from unsecure locations to virtual or remote PCs.

Limitations

• Video reception on zero clients is generally good.
• Video transmission and peripheral support, however, can be limited or marginal, depending on the use case.
