Premier EMI Filters

In high-security environments where data integrity and information security are paramount, safeguarding against electromagnetic leaks is just as critical as protecting against cyber threats. TEMPEST EMI Power Line Filters from Premier Filters are purpose-built to defend sensitive installations against compromising emanations  — and the cabinet-style design offers scalable, rugged, and code-compliant solutions for real-world secure environments. 🔐 What Are TEMPEST EMI Filters? TEMPEST refers to a set of U.S. and NATO standards aimed at preventing unintended electromagnetic emissions from being used to compromise or intercept classified information. These standards apply to facilities that process sensitive national security data — such as SCIFs , embassies , command centers , and defense R&D labs . TEMPEST EMI filters are used to: 🛡️ Prevent data leakage through power lines 📡 Block inbound electromagnetic signals from breaching secure spaces ⚙️ Ensure compliance with N...

In today’s digital age, the threat to classified information doesn’t just come from cyberattacks  — it also comes from electromagnetic interference (EMI). For SCIFs (Sensitive Compartmented Information Facilities) , securing control lines and data transmission pathways against EMI is critical. That’s why Premier Filters offers specialized EMI Power Line Filters for SCIF control and data circuits , ensuring total electromagnetic isolation and compliance with strict national security standards. 🔗 Explore the SCIF Filter Range The Challenge: Securing Information Beyond Firewalls SCIFs are designed to store, process, or discuss classified and sensitive information , making them high-value targets for surveillance and data breaches. Even unintentional emissions through power or control lines can act as a vulnerability — exposing confidential information to interception. To counter this, all conductive paths (power, data, HVAC, fire alarm, lighting, etc.) entering or exiting the SCIF mus...
