Sensitive Compartmented Information Facility (SCIF) interfaces are essential components for secure facilities, providing robust shielding against electromagnetic interference (EMI), radio frequency (RF) signals, and cyber threats to protect classified data and operations. Ramsey Electronics, a leading faraday cage manufacturer, specializes in designing and installing SCIF interfaces that meet stringent government standards for defense, government, and corporate environments. This ultimate guide covers how SCIF interfaces work, their benefits, installation process, and why Ramsey Electronics is the trusted choice for secure facility shielding.
SCIF interfaces from Ramsey Electronics deliver 100 dB shielding, ensuring data security and compliance for secure facilities, with costs ranging from $2,000–$10,000.
What Are SCIF Interfaces and How Do They Work?
SCIF interfaces are specialized shielding components, such as conductive doors, vents, and cable entries, integrated into secure facilities to block EMI and RF signals. They create a continuous conductive barrier, achieving up to 100 dB attenuation, as per IEEE standards, to prevent signal leakage and protect sensitive operations. Ramsey Electronics designs SCIF interfaces compliant with MIL-STD and DCID 6/9, ensuring no external signals compromise data security.

Key Benefits of SCIF Interfaces
SCIF interfaces offer numerous advantages for secure facilities:
Data Security
Blocks 99.999% of EMI and RF signals, preventing unauthorized access to classified information.
Compliance
Meets DCID 6/9 and MIL-STD standards for government and military applications.
EMP Protection
Shields electronics from electromagnetic pulses, ensuring operational continuity.
Durability
Constructed with premium materials like copper and aluminum for long-term performance.
Customization
Tailored to fit specific facility layouts, from small rooms to large complexes.
Cyber Threat Mitigation
Prevents wireless hacking attempts, safeguarding sensitive data.
Operational Reliability
Ensures equipment functions without interference in high-security settings.
Did You Know? SCIF interfaces can block 99.999% of electromagnetic signals, ensuring compliance with federal security standards, per NIST guidelines.
