SHERIDAN, WYOMING – August 5, 2025 – In a world where drones are buzzing into places they shouldn’t be, a quiet revolution in airspace security is taking flight—without making a sound. A European consortium led by German security firm hensec has launched a next-generation, fully passive airspace surveillance system designed to protect critical infrastructure without needing complicated licenses or active signals.
Think of it as a silent watchdog—always alert, never barking.
Why this matters: Drone risk is real, and growing
With unauthorized drones increasingly spotted over ports, energy plants, and even airports, the stakes for civil airspace security have never been higher. In just the first half of this year, Rhineland-Palatinate reported nearly as many drone incidents as in all of 2024. The recent sightings over restricted areas in Wilhelmshaven are only the tip of the iceberg.
While hobby pilots might mean no harm, a single mishap—or worse, a targeted jamming attempt—can spell disaster for sensitive infrastructure.
That’s where hensec’s solution steps in.
A passive solution with powerful coverage
Unlike many conventional systems, hensec’s innovation doesn’t send out any signals itself. That means:
- No regulatory red tape for signal emissions
- Full mobility for temporary or event-specific setups
- Seamless operation in urban, rural, or high-risk areas
The system combines three silent but highly effective “listeners”:
- Radio signal analysis – to detect command signals and interference
- Passive radar – to sense movement without broadcasting anything
- Radio telemetry – to track and classify flying objects
These sensors work in concert to paint a complete real-time picture of the airspace, covering everything from hobby drones and helicopters to ultralight aircraft—and even birds.
Made in Europe, with digital sovereignty in mind
One standout feature: everything in this system is 100% EU-made. That’s not just a nice badge of origin—it ensures there are no foreign dependencies, export issues, or unknown third-party data handlers.
Partners include:
- Aaronia (Germany) for radio analytics
- Parasol (Germany) for passive radar
- Airsenso (Germany) for telemetry
- GPSPatron (Poland) for anti-GNSS interference protection
With data centers in Hesse and Thuringia, and operations centers in Baden-Württemberg and Bavaria, the infrastructure is as sovereign as it is secure.
Kevin Heneka, founder of hensec, explains: “We are probably the only provider on the market that is not backed by a foreign corporation or sources essential components from outside the EU.”
Real-time insights that keep operations safe
This system isn’t just theoretical—it’s already in use. At energy-intensive production facilities and transport hubs, it has successfully:
- Differentiated between emergency-response drones and rogue flyers
- Created shared situational maps across agencies (fire, police, rescue)
- Documented both permitted and unauthorized flights in real time
This precision means fewer false alarms and better coordination when every second counts.
Where you can use it
Whether you're safeguarding a power plant, monitoring an airport, or coordinating security at a major event, this system flexes to fit:
- Stationary installation for long-term protection
- Mobile deployments for temporary needs like public events or crisis zones
- Scalable integration across wider regional or national infrastructure
And since it requires no frequency allocation, approvals, or foreign hardware, deployment is faster, safer, and more flexible.
A smarter future for airspace safety
As drone usage continues to rise—both for good and ill—Europe needs modern solutions that respect privacy, operate quietly, and deliver fast, accurate insights. hensec’s system checks all these boxes while reinforcing EU values of independence and innovation.
Kevin Heneka sums it up: “We offer companies a modular, scalable security concept that is tailored to European requirements and can be flexibly deployed in a variety of scenarios.”
