Metatron Citadel

Metatron Citadel is a premier access control, surveillance, and I&HAS solution developed by Metatron Access Control and designed for military and intelligence applications. It advertises complete vertical integration of all three common parts of facility security infrastructure, and is certified to both EN 50131 Grade 5 and Raven IS-2171-177 Class 3. It also offers integration with the IFF interface of the Metatron Active Defence SRX line of automated fire control systems, as well as those manufactured by Helios Corporation and CORE Weapon Systems. Some Citadel components include Farsight, Panopticon, Sine, and Slate.

Metatron Citadel encompasses a "complete tamper protection" policy. All installed elements of the system, from the most basic of LIDAR sensors to card/PIN panels are shielded by a tamper-responsive mesh that detects attempts at drilling, probing, or manipulation. This extends to the cabling between components, where all communication uses a bus topology and quantum encryption, preventing substitution. Furthermore, all components are built ruggedised as standard, and can withstand advanced physical attacks, gunfire, and even explosions.
