A10 Networks reported that it has acquired TrojAI, a specialized AI security firm that focuses on securing, testing and governing AI applications and agentic workflows. The announcement coincided with a 3.6% jump in A10 shares (NYSE:ATEN) following the news.
TrojAI brings two principal layers of protection to A10’s security offerings. The first is red teaming, which probes models, agents and applications for vulnerabilities during development. The second is real-time threat protection, designed to defend those systems while they run in production.
"TrojAI is a natural fit for A10, strategically and operationally," said Dhrupad Trivedi, President and Chief Executive Officer of A10 Networks. "Pairing our hardware-based AI firewall with TrojAI’s software-based red teaming and runtime protection helps customers adopt AI quickly and confidently, protecting their models, data, and agents without sacrificing the latency or availability they rely on us for, whether on-premises, in the cloud, or hybrid."
According to A10, the expectation is to fold TrojAI’s capabilities into the company’s security portfolio so customers can run secured AI where their data resides. The company has not disclosed the financial terms of the transaction.
A10 also stated that it does not expect the acquisition to have a material impact on its financial results for fiscal year 2026.
The move is positioned as an enhancement to A10’s ability to provide AI security across deployment environments, combining hardware- and software-based defenses aimed at both development-time testing and runtime protection.
