Verifying Network Isolation Without Disrupting Legacy OT Environments
Many industrial systems used today were built decades ago to run non-stop for years. In these environments, keeping systems up and running safely is the top requirement. Because of this, companies often prefer to live with older, known risks rather than try new security tools that might cause problems. Many older networks have unrecorded firewall rules, aging equipment, unsegmented networks, and unknown dependencies. These risks are often accepted simply because they have existed for years without causing a breakdown. Cybersecurity teams know they need to fix these issues, but it is hard to know where to start. Many security tools claim to be “passive” or “non-invasive”, meaning they won’t disturb the network, but OT teams need real proof before they can trust those claims.
Easy Implementation of SensorFu Beacon
When the founders of SensorFu designed the SensorFu Beacon, their core mission was simplicity. They wanted to ensure that anyone with basic IT skills could easily deploy it, and most importantly, that it would never disrupt active Operational Technology (OT) environments. True to this vision, getting SensorFu Beacons up and running is remarkably straightforward.
Seamless Deployment & Flexible Hosting
To begin, a technical contact with the authority and network access is needed to deploy the Beacons and manage the local network infrastructure. From there, the requirements are minimal:
-
IP Allocation: SensorFu Beacon requires an IP address, subnet, default GW, or DHCP
-
Virtual Platforms: Easily host Beacons on 64-bit x86 virtual environments using OVA or ISO images for VMware, Hyper-V, VirtualBox, and KVM-based platforms.
-
Physical Platforms: For physical deployments, SensorFu provides a Raspberry Pi-based appliance equipped with a 230 VAC power supply and an RJ45 access port.
Designed for maximum efficiency, the system maintains a lightweight network footprint with a traffic profile of just one packet per second. It also seamlessly integrates into your existing enterprise ecosystem with:
-
Single Sign-On (SSO): Out-of-the-box support for Microsoft Entra, Google, and Okta.
-
SIEM/SOAR/SOC Integration: Dedicated documentation to guide you through forwarding alerts directly to your security operations center.
Real-World Success: SSAB’s Experience
Instead of requiring days of tedious setup, SensorFu is built for rapid implementation. As our customer, SSAB, shared:
“Configuring and downloading the beacons from the management interface was smooth, and there was no need to read the instructions at all.”
SSAB successfully deployed a mix of both virtual and physical Beacons. While they experienced minor external delays when their IT partner deployed the virtual machines to an HCI environment, they noted that SensorFu’s support team was readily available to help keep things on track.
