We love getting feedback from our clients about our product, SensorFu Beacon. Imagine our surprise however, when one of our clients called to tell us that not only had Beacon worked well, but it was apparently capable of achieving digital immortality.
A case study detailing how Eximprod’s ES200 vRTU tech enabled the rapid rollout of 100 SensorFu Beacons across geographically dispersed substations and the key insights gained.
Describes a “tarpit”-style defense that not only slows down but actively confuses and traps hostile network scans, flipping defense into offense.

It is important that companies identify the material that they need to protect to enable efficient protection. Complex isolated networks are not always as well isolated as you would think. The feasibility study (Toteutettavuustutkimus) conducted by the National Cyber Security Centre Finland (NCSC-FI) successfully tested and developed new, agile and scalable methods for improving these areas.
Water supply professionals and government planners have long been aware that urban water systems are a lucrative target for cyber adversaries. Water utilities are heavily using industrial control system (ICS) networks to control the physical processes essential to water treatment and distribution systems. Network isolation and segmentation are key protections that prevent unauthorized access to these SCADA/ICS systems and to keep hostile adversaries at bay.
We have delivered our SensorFu Beacons into a real production networks. To celebrate this milestone of real deployments, we are writing about the lessons learned and experiences gained while working with our early adopters.
