Zscaler has announced the acquisition of SPLX, an AI security specialist, in a move to expand its Zero Trust Exchange platform with capabilities designed to secure artificial intelligence systems from development through deployment.
The acquisition adds new features for AI asset discovery, automated red teaming, and governance — areas that have become increasingly important as enterprises adopt large-scale AI models and agents across hybrid environments. Zscaler said the integration of SPLX’s technology would extend its platform to help organisations identify vulnerabilities and apply consistent security controls across the full AI lifecycle.
Zscaler founder and CEO Jay Chaudhry said the acquisition reflects the company’s strategy to address emerging risks in AI adoption. “AI is creating enormous value, but its full potential can only be realised when it can be secured,” he said. “By combining SPLX’s technology with the intelligence and data protection of the Zscaler Zero Trust Exchange, we can secure the entire AI lifecycle on one platform and give customers the confidence to safely embrace AI.”
Industry analysts have warned that the rapid growth of AI infrastructure — projected to exceed USD 250 billion by the end of 2025 — is creating new security challenges. The proliferation of large language models, autonomous agents, and Model Context Protocol servers has expanded the potential attack surface and increased the need for discovery, governance, and continuous testing of AI systems.
SPLX has developed tools for AI red teaming, asset management, threat inspection, and prompt hardening that simulate domain-specific attack scenarios to identify vulnerabilities. Its platform automates discovery and risk assessment across public and private AI deployments, including models, workflows, and retrieval-augmented generation (RAG) systems.
Following the acquisition, SPLX’s capabilities will become part of Zscaler’s AI Runtime Guardrails and Governance suite, extending protection to development environments and runtime operations. The company said this will allow customers to apply unified guardrails, improve compliance, and automate mitigation across AI assets and data pipelines.
Kristian Kamber, CEO and co-founder of SPLX, said the two companies share a common vision for addressing the security challenges created by expanding AI infrastructure. “By joining forces, we’ll bring our innovation to one of the most trusted security platforms in the world, securing AI innovation at the speed organisations are adopting it,” he said.
The deal positions Zscaler to compete more directly in the emerging AI security market, where enterprises are seeking integrated solutions to protect sensitive data and prevent model manipulation as AI systems become more deeply embedded in business operations.
