About TXOne Networks

TXOne Networks stands as a specialized entity in the industrial cybersecurity sector, concentrating on the protection of operational technology (OT) and industrial control systems (ICS). The company was established in 2018 as a joint venture between Trend Micro, a global cybersecurity firm, and Moxa, a specialist in industrial infrastructure. This strategic formation combines Trend Micro's extensive cybersecurity expertise with Moxa's deep knowledge of industrial networking and protocols. The firm is headquartered in Taipei, Taiwan, with a significant U.S. presence in Irving, Texas.

The company's leadership team includes CEO Dr. Terence Liu, who previously served as a Vice President at Trend Micro and was the CEO of Broadweb, a company specializing in Deep Packet-Inspection (DPI) that Trend Micro acquired in 2013. Akihiko Omikawa, an Executive Vice President at Trend Micro, serves as Chairman of TXOne Networks. The business was founded to address the security gap created as isolated OT networks increasingly connect to corporate IT networks, exposing industrial machinery not originally designed for network connectivity to cyber threats. Since its inception, TXOne has secured significant funding, including a $12.9 million Series A in August 2021, a $70 million Series B in August 2022, and a $51 million Series B extension in May 2024, bringing its total funding to $134 million.

TXOne Networks' business model is centered on providing OT-native cybersecurity solutions designed to safeguard industrial environments without disrupting operations. The company serves a broad client base, including leading manufacturers and critical infrastructure operators across sectors like semiconductors, automotive, healthcare, food and beverage, and energy. Revenue is generated through the sale of its specialized hardware and software security products. The firm's core philosophy is "OT Zero Trust," which applies a "never trust, always verify" principle to industrial environments. This approach is designed to provide granular control and protection for critical assets.

The product portfolio is structured to offer defense-in-depth, with both network-based and endpoint-based solutions. Key offerings include the Element series for security inspection of assets and removable media; the Stellar series for OT-native endpoint protection on critical devices; and the Edge series of network security appliances for network segmentation and threat prevention. These products are managed through the SageOne central management console, which provides unified visibility and control over cyber-physical systems (CPS). A distinct feature is the ability to provide virtual patching for legacy and unpatched systems, a common challenge in OT environments where downtime for updates is often not feasible.
