The Guardian is ergonomically designed for tabletop use, offers excellent convenience and has been verified by independent third-party laboratories to defeat all TEMPEST, audio and video Technical Espionage threats inherent to PEDs. The Guardian also features a storage bay that can be reconfigured in a 10 slot compartment, a 20 slot compartment or open bay configuration. The Guardian also holds approximately 40 cell phone style PEDs or at least 5 tablet style computers. It also features 10 internal PED charging ports that allow PEDs to be securely charged within the Guardian. This prevents PEDs from being charged in an unsecure manner, in an open office environment, which could place classified, sensitive and private information at risk.
