What is line sweeping?

Line sweeping is a process of inspecting, detecting, and removing potential wiretaps or listening devices that may be hidden in communications systems, such as phone lines or data networks. This service is often offered by security and investigation firms to protect confidential information from being intercepted by competitors, adversaries, or other unauthorized parties. Line sweeping involves using sophisticated electronic equipment, such as spectrum analyzers, signal detectors, and thermal imaging cameras, to scan and analyze the electromagnetic spectrum for any anomalous signals or radiation. Any suspicious signals or anomalies will be further investigated and eliminated by a team of trained professionals. Line sweeping is an essential component of counter-espionage and counter-surveillance operations, particularly in high-risk industries, such as government, defense, and corporate intelligence.
