SignalSecure
SignalSecure is an innovative dual-use, cellular interdiction solution designed to combat the use of illegal cellphones and unauthorized wireless devices within prisons and secured facilities. These contraband devices are used to coordinate criminal activity, contraband trade, escape attempts, corporate espionage, and external communications that threaten public safety. With SignalSecure, we give prisons and other high-security sites a fast, FCC-compliant way to detect, mitigate, locate, and disconnect illegal phones—protecting people, operations, and sensitive information without disrupting authorized communications.
ADRESSING ONGOING THREATS
- Constant Interdiction: Covertly detects, mitigates, locates, confirms, and disconnects unauthorized wireless devices in real time, in full alignment with FCC 47 C.F.R. § 20.23.
- Denial Of Service (DOS): Optional feature that prevents unauthorized devices from connecting to a cellular network.
- Pinpoint Accuracy: Handheld “walk-down” tools locate rogue cellular devices and optional in-building sensors detect unauthorized Wi-Fi hotstops or networks connections.
- Zero Collateral Impact: Proprietary algorithms and scan techniques develop a target list of contraband phones while leaving approved devices untouched.
- Scalable Protection: Safeguards prisons, military bases, embassies, and any facility that bans personal devices.
- Actionable Intelligence: Provides identification and location details on wireless devices for rapid response and long-term planning.
- Proven Expertise: SOC has years of experience developing custom wireless solutions including network architecture, network security, antenna installation, customized cellular solutions, and network deployments.
