EMP Cabinets- Secure IT Level 3 with EMP

Physical IT Security

Companies today face rapidly multiplying, increasingly sophisticated security risks. Even the advanced IT systems that drive global business and underpin our society are susceptible to the latest state-of-the-art threats. As the complexity of our systems grows, so too does our reliance upon them. And when they go down, the consequences can be critical. From a technological standpoint, the proverb ‘the bigger they are, the harder they fall’ is very true!

Governments and corporations alike face the very real risk of a future attack by Electromagnetic Pulse (EMP), which criminals, terrorists and other destabilising agencies can use to disable servers and other electrical equipment for financial or strategic gain. The targeting of advanced technologies to access sensitive data can have catastrophic implications. Protecting them—physically—is more important than ever.

Gunnebo has developed the Secure-IT Class 3 EMP range to protect servers from intentional and malicious attacks or information gathering. Class 3 cabinets are constructed to meet the stringent requirements of burglary standard SS 3492, additionally the EMP-certified models ensure that mission-critical IT systems are insulated from the harmful effects of Electromagnetic Pulse (EMP), electronic eavesdropping, and the consequences of targeted, unauthorised access.
