TXOne Networks, which builds and sells tech for securing industrial IoT environments, has raised a $70M Series B led by TGVest Capital
TXOne Networks, a joint venture between cybersecurity firm Trend Micro and industrial networking solutions provider Moxa, has banked $70 million in new venture capital funding.
Context & Ripple Effects
TXOne Networks exists because Trend Micro decided five years ago that industrial IoT was worth seeding directly: its $100M venture fund targeting IoT startups set up the joint venture with Moxa, whose industrial networking hardware gives TXOne distribution inside factories rather than just another endpoint agent.
The $70M Series B led by TGVest Capital makes TXOne the largest-funded company in this corpus's industrial-IoT security lineage, ahead of CyberX's $18M Series B in 2018 and ZingBox's $22M round in 2017. It also lands at an awkward moment for its parent: Trend Micro, valued around $6.5B, is reportedly exploring a sale after buyout interest.
First-order effects
- TXOne gets a war chest to scale OT/IoT security products independently of its parents' balance sheets, while Moxa's installed base of industrial networking gear becomes the go-to-market channel the money is meant to exploit.
- Trend Micro now has a more valuable asset on its books mid-sale-exploration — alongside other spinouts like SOC-as-a-service firm Cysiv, which it incubated before its own $26M Series A.
Second-order effects
- Rivals in industrial-systems security face a competitor backed by both a major antivirus vendor and the equipment maker whose devices sit on factory floors — forcing them to seek equivalent hardware partnerships or acquisition to match that distribution.
- Any acquirer of Trend Micro inherits a stake in TXOne plus the venture-fund portfolio, meaning the parent's sale process now prices in a security-startup equity book, not just a product business.
Third-order effects
- The pattern across these rounds — vendor-backed JVs, corporate funds, and spinouts — points toward industrial security consolidating around players who control device-level access, with standalone IoT-security startups increasingly needing a hardware or platform anchor to stay competitive.
- If ransomware pressure on manufacturing persists (Trend Micro itself flagged manufacturing as the most-targeted sector in Q3 2020), expect regulators and insurers to keep pulling OT security from optional to mandated, widening the market TXOne's raise is positioned for.
The trend: Industrial IoT security is graduating from seed-stage experiments funded by corporate venture arms to large institutional rounds, as IT-security vendors embed themselves in operational technology through hardware partnerships.
