In complex OT and ICS environments, you cannot manage what you cannot verify. Firewalls, VLANs, routing rules, VPNs and air-gaps may be designed correctly, but configurations drift, maintenance tunnels appear, and small exceptions become permanent risks.
The SensorFu Beacon 14-Day Trial gives you practical evidence. By deploying lightweight Beacons into your most sensitive network segments, you move from assuming isolation to proving it.
Beacon provides a continuous heartbeat for isolated segments.
Lightweight, non-intrusive and designed for sensitive environments.
If a Beacon can call home, the segment is not isolated.
TCP/UDP (v4/v6), DNS tunneling, ICMP, broadcasting, spoofing and more.
Critical infrastructure and ICS/OT security policies require segmentation e.g., ISO/IEC ISO27002:2022 Control 8.22 - Segregation of Networks. In addition, under the NIS2 Directive (Directive (EU) 2022/2555), network segmentation and segregation are critical, non-negotiable risk management measures required for essential and important entities to bolster cyber resilience.
Fill out the trial request form. We review requests to ensure a professional context.
You receive access to Beacon Home and tailored trial instructions.
Launch your first Beacon as an application, container, VM or device.
If Beacon succeeds in reaching home, Beacon Home shows your leak.
Identify misconfigurations, forgotten routes or unwanted connectivity.
SensorFu is based in Oulu, Finland, and focuses on practical cybersecurity for organizations that depend on reliable network segmentation. The company’s Beacon product is designed especially for OT environments where network changes must be safe, controlled and easy to understand.
Tell us briefly who you are and what kind of environment you want to evaluate. We review trial requests to help you get started with the right setup.
Evaluation without financial commitment.
You stay in control of your environment.
Operated from Finland and the EU.
Yes. The 14-day trial does not require a credit card and provides full access to the necessary tools for testing isolation.
Beacon is designed to be lightweight and non-intrusive. It does not rely on aggressive scanning or high-bandwidth activity, making it safe for sensitive PLC and industrial controller environments.
If a Beacon reaches home from an isolated segment, it means the segment has a path out. Beacon Home will provide technical details about the escape path (e.g., protocol used) to help you investigate the root cause.
Your first Beacon can typically be deployed in minutes. Depending on your choice (VM, Docker, etc.), it's usually just a matter of launching the image and verifying connectivity to Beacon Home.
No. The trial is designed around selected Beacon deployments in the specific segments you want to verify. You don't need agents on every endpoint.
