Safeguarding Secure Spaces with Advanced RF & STC Testing
Effective Radio Frequency (RF) and Acoustic (STC) testing is essential to secure facility construction and accreditation. As TEMPEST threats evolve, simply understanding RF and STC vulnerabilities isn't enough—you need experts who can anticipate and adapt.
At SPG, our team includes former Certified TEMPEST Technical Authorities (CTTAs) with deep expertise in RF/STC testing techniques. We deliver precise assessments to help ensure your facility meets the highest security standards.

Expert-Led Testing
Our team of RF and STC testing specialists includes former CTTAs who bring decades of experience in mitigating threats. With a focus on evolving surveillance risks, we deliver testing protocols grounded in both policy and real-world expertise.
2
Comprehensive Methodology
We assess three key acoustic metrics—Sound Transmission Class (STC), Noise Isolation Class (NIC), and Speech Intelligibility—to evaluate how effectively your space contains sound. Our RF testing methodology also detects signal leakage using highly sensitive, policy-compliant instruments.

Unseen Threats, Constantly Evolving
Common workplace devices—microprocessors, monitors, printers, and cables—all emit RF signals that can be intercepted and reconstructed. Without proper testing and controls, these signals can compromise secure communications.
4
Secure from the Inside Out
Sound travels through air, water, and structural materials. If not properly mitigated, it can breach secure boundaries. Our testing identifies weaknesses in walls, doors, and construction details—ensuring your space is protected against both eavesdropping and electromagnetic leakage.
