Area: Advanced Manufacturing and Semiconductor Production
Requirement: Independent audit of wireless infrastructure and covert monitoring for unauthorised network activity
A global leader in semiconductor manufacturing required a detailed audit of its wireless infrastructure following concerns about unauthorised connectivity within restricted cleanroom environments.
With strict “no device” policies for guests and controlled device registration for employees, the facility demanded a non-intrusive, real-time monitoring solution capable of identifying any unapproved transmissions, tethered devices, or embedded wireless systems.
Air Sheriff was deployed to provide complete visibility of the facility’s wireless ecosystem – ensuring full compliance, operational integrity, and long-term assurance of intellectual property protection.
Within hours of deployment, Air Sheriff uncovered a hidden wireless network embedded within the facility’s LED lighting system. The network periodically changed its SSID and concealed microphones designed to capture audio from nearby workstations. In addition, nine tethering devices were found transmitting sensitive design data outside approved channels – activity invisible to standard cybersecurity tools.
Following the investigation, unauthorised devices were removed, vulnerabilities were remediated, and enhanced monitoring protocols were introduced. The client has since retained Air Sheriff as a core component of its ongoing long-term cyber assurance and compliance strategy.
Installed without disrupting operations or alerting staff.
Critical vulnerabilities identified within the first days of monitoring.
Delivered a true, unbiased picture of wireless activity.
Continued monitoring provides sustained visibility and protection.
Due to the confidential nature of Air Sheriff’s work within high-value manufacturing environments, client identities remain undisclosed.
The testimonial below reflects verified feedback from a senior operations director at the semiconductor facility.
We know security can feel complex, so we’ve answered some of the most common questions about how Air Sheriff works and what makes it different.
Air Sheriff identifies and monitors Wi-Fi, Bluetooth, cellular, and IoT devices, detecting unusual behaviour or unauthorized networks.
No. Air Sheriff only monitors device behaviour and network activity. It never collects, stores, or inspects the actual data transmitted.
Very easy. Air Sheriff detectors only need power and mobile data. No integration with existing networks or infrastructure is required.
Air Sheriff provides independent, real-time monitoring of WiFi, Bluetooth, cellular, and IoT networks. Trusted in defence, aviation, government, and critical industries worldwide, our technology delivers unobtrusive cyber assurance, helping organisations detect hidden threats and secure their digital environment.
