Question #378: Do you provide Communications Assistance for Law Enforcement Act (CALEA) functionality for the GUARD?
Answer: No.

Question #375: What operating system is installed on the GUARD?
Answer: All Guards come with OpenWRT preinstalled. This is a Linux based distribution specialized for firewall and routing tasks. You can find out more about OpenWrt at

Question #376: Is it possible to use some other OS than OpenWrt?
Answer: Certainly. But at the moment, only a Linux kernel is available from MPL AG, so only Linux based ARM operating systems (like, for example, debian) are supported. Please contact MPL support if you need assistance.
