About Vigilant Sky
Defining the New Standard of Airspace Sovereignty.
Vigilant Sky was founded at the intersection of Signal Intelligence (SIGINT) and Tactical Security. As the barrier to entry for Unmanned Aircraft Systems (UAS) collapsed, we recognized a critical vulnerability in global infrastructure: the "Airspace Gap."
​
Traditional security focuses on the x and y axes—fences, bollards, and biometric access. We were built to master the z-axis. Our mission is to provide high-performance, non-kinetic drone detection for environments where silence, precision, and legal compliance are non-negotiable.


Intelligence Should Be Felt, Not Heard.
In the counter-UAS (C-UAS) industry, there are two paths: Active and Passive.
-
The Active Flaw: Radar and Jamming systems "scream" into the electromagnetic spectrum. This creates "spectral noise" that interferes with Wi-Fi, medical equipment, and emergency communications. Furthermore, active emissions serve as a beacon for electronic counter-surveillance.
-
The Vigilant Sky Advantage: We believe in Total Spectral Silence. By utilizing advanced Passive RF sensing, our systems act as a high-fidelity "digital ear." We detect the unique telemetry and video downlinks of drones without emitting a single watt of traceable radiation. This makes our technology the primary choice for "zero-fail" environments like hospitals, airports, and high-density urban centers.

Engineering the Invisible Perimeter.
Our team is comprised of veterans from the aerospace, defense, and signal processing industries. We have distilled decades of electronic warfare experience into a streamlined, enterprise-ready platform.
​
I. The Global Signal Library
Our software doesn't guess; it knows. We maintain a proprietary database of thousands of drone "fingerprints." From off-the-shelf hobbyist models to specialized DIY "dark" drones and long-range commercial platforms, our AI classifies the make, model, and frequency-hopping protocol in less than 200 milliseconds.
​
II. Time Difference of Arrival (TDOA) Precision
While cheaper systems use simple "Signal Strength" (RSSI) to estimate distance, Vigilant Sky utilizes TDOA (Time Difference of Arrival). By synchronizing multiple sensors with nanosecond precision, we triangulate the exact GPS origin of the signal. This allows us to locate the pilot—often before the drone even leaves the ground.
​
III. Future-Proof Integration (API-First)
We don't believe in "closed" systems. Vigilant Sky is built on an Open Architecture. We act as a "Force Multiplier" by feeding real-time drone coordinates into your existing Global Security Operations Center (GSOC), Video Management Systems (VMS), and automated alarm triggers.


Security Without the Regulatory Burden.
Because our systems are strictly passive (receive-only), they are 100% FCC and FAA compliant. Unlike jammers or spoofers—which are heavily restricted and often illegal for private use—Vigilant Sky provides a legal, "prosecutor-ready" forensic trail. Every flight path, serial number, and MAC address is logged, providing the evidence needed for law enforcement intervention and legal recourse.
Guided by Experience. Driven by Innovation.
The Vigilant Sky leadership team is comprised of veterans from the United States Intelligence Community (IC) and the Defense Signal Processing sector. With over 40 years of combined expertise in Electronic Warfare (EW) and tactical security integration, we have transitioned elite military-grade technology into a streamlined, civilian-ready platform.
​
Our engineers have been at the forefront of the C-UAS revolution since its inception, moving beyond simple detection to create a forensic-first ecosystem. We aren't just technologists; we are security practitioners who understand that in a high-stakes environment, intelligence is the only true deterrent.
