UNIVERSITY OF LJUBLJANA SPIN-OUT · EU

Cyber deception and threat intelligence, engineered in the EU.

We turn years of research on real attackers into security products. Our team has run custom-built honeynets across the globe for more than 10 years; today that work powers CTIshark, our threat intelligence and deception platform.

ABOUT US

A research lab that grew into a security company.

Cyber Systems was founded by researchers from the Laboratory for Telecommunications at the University of Ljubljana’s Faculty of Electrical Engineering. Our team brings decades of combined experience in networks, telecommunications and cybersecurity.

We design our own sensors, operate our own infrastructure and support our customers directly. Every finding we deliver can be traced to the evidence behind it.

RESEARCH AND TRACK RECORD

Years of watching real attackers.

Before CTIshark was a product, it was research: national and European projects, open data and peer-reviewed work on honeypots and the security of critical infrastructure.

Research work was carried out by our team at the University of Ljubljana.
