Hensec develops integrated port security platform

German security company hensec secure solutions has developed Portags, an integrated monitoring platform designed to protect ports against airborne threats and disruption to satellite navigation systems.

The system combines multiple detection technologies, including radio-frequency sensors, passive radar and GNSS analysis, into a single operational view.

The development comes as countries around the Baltic Sea increase cooperation to counter hybrid threats. Germany, Denmark, Estonia, Finland, Latvia, Lithuania, Poland, Sweden and Norway agreed at a Baltic Sea Security Summit in late August to strengthen information sharing and establish a joint task force.

“Shared situational awareness isn’t achieved simply by installing more and more individual sensors. What matters is bringing their data together, correlating it and presenting it in a way that allows security teams to quickly understand what is actually happening,” said Kevin Heneka, managing director of hensec secure solutions.

Portags is designed to monitor the airspace above ports for potential airborne objects, including drones, while simultaneously assessing the reliability of GNSS signals. RF sensors can identify drone communication, control and telemetry signals, including Remote ID data, while passive radar can detect non-transmitting or non-cooperative airborne objects.

The platform also analyses GNSS signals for interference, including jamming and spoofing. Jamming can block or severely degrade satellite signals, while spoofing provides receivers with false but plausible navigation or timing information. Hensec said such interference can affect maritime and air traffic, communications, critical infrastructure and autonomous systems.

The company said research conducted with hensec during a 2025 measurement campaign in the southern Baltic Sea identified combined jamming and spoofing activity. In some instances, stronger interference was recorded at sea than in Gdansk.

“Where drone activity and interference with navigation signals can occur at the same time, relying on a single sensor source is not enough,” Heneka said.

Portags uses sensor fusion to correlate RF, radar, telemetry and GNSS information before presenting relevant data through a Common Operating Picture.

The modular system can be deployed in stationary or mobile configurations across container terminals, tank farms, port entrances and automated facilities, with open interfaces allowing integration into existing operations centres.
