About TXOne Networks

TXOne Networks sells security solutions that integrate across all levels of the Purdue model. TXOne Complete integrates Edge network security, Stellar endpoint protection, Element inspection, and Sennin orchestration into a unified architecture. TXOne Networks designs its solutions to operate at Levels 0-3 of the Purdue model, where traditional IT security tools cannot function effectively. The Purdue Enterprise Reference Architecture, called the Purdue Model, is a structural model for industrial control system security.[1][5][15]

TXOne Edge blocks at the OT command level. Edge provides inline threat prevention across 180+ industrial protocols, both standard and proprietary, with 1,500+ OT-native signatures. Edge includes an AI engine that finds assets, writes policy, and prioritizes alerts. Edge deploys inline on hardware or virtual appliances without IP address changes or network redesign. Edge offers native support for 180+ industrial protocols with L2 to L7 inspection and 1,500+ OT-native threat signatures. Edge uses ZDI research-backed signatures to protect legacy systems from known vulnerabilities without requiring system modifications or downtime. Edge network security includes Gen3 hardware bypass on every segment with Universal Bypass for uplink disconnection. Edge applies the same inspection, CPSDR detection, and policy enforcement on hardware and virtual appliances.[8][11]

TXOne Stellar delivers endpoint security in two editions. Stellar Discover installs in one minute with no drivers and no kernel access. Stellar Protect comes in an ICS Edition for the full prevention suite and a Kiosk Edition for the most constrained legacy endpoints. The ICS Edition includes application lockdown, USB device control, network access control, and script-based plus fileless attack prevention. The Kiosk Edition of Stellar Protect is the lite counterpart, with the same agent footprint scaled down for single-purpose endpoints, HMIs, and the oldest legacy systems that cannot run the full ICS agent.[2][7][16]

StellarOne is the single-pane management console for every Stellar deployment. StellarOne inventories Discover sensors, pushes policies to Protect agents, coordinates one-click upgrades from sensor to agent, and forwards events to Splunk, Microsoft Sentinel, and QRadar. StellarOne maps to IEC 62443 and NIST CSF requirements. StellarOne enforces role-based access control and approval workflows for policy deployment, agent upgrades, and configuration changes. StellarOne supports air-gapped deployments for ICS and Kiosk agents with USB pattern updates. Stellar telemetry feeds SenninOne's VSAR vulnerability scoring for operational-context risk prioritization.[7][17]

Element validates devices and media without software installation, system modifications, or network requirements. Element is 100% air-gap compatible. Element scans at 7,200 files per minute. Portable Inspector plugs into any USB port to scan for malware, collect asset information, and verify system integrity without software installation or system modifications. Portable Inspector provides agentless malware scanning and asset discovery from a USB device and supports 80+ operating systems from Windows 2000 through the latest Linux distributions. The Pro Edition of Portable Inspector adds AES-256 hardware-encrypted storage for validated file transfer into air-gapped environments.[5][7][10][11][16][18]

ElementOne is a centralized management console for a Portable Inspector and Safe Port fleet, with one dashboard for data scanning, device health, and compliance reporting. ElementOne aggregates scan results, asset inventories, and threat detections from 1,000+ Portable Inspector and Safe Port devices into a unified security posture dashboard. ElementOne automates pattern file distribution to keep every device current. ElementOne deploys as a virtual machine for centralized management of all security inspection devices. SenninRecon provides automated discovery and risk scoring, with centralized asset visibility across all sites from a single console.[5][7][8][9][10][11][16][17][18][19][20]
