Zscaler has acquired SPLX, an innovative AI security pioneer known for its work in AI red teaming, governance, and risk management.
The move strengthens Zscaler’s position in the fast-growing field of AI-driven cybersecurity and expands the company’s Zero Trust Exchange™ platform with advanced AI security capabilities.
The acquisition aims to extend Zscaler’s platform with shift-left AI asset discovery, automated red teaming, and governance features, enabling organisations to secure their AI investments from development through to deployment. The financial terms of the deal have not been disclosed.
Zscaler, listed on the NASDAQ under the ticker ZS, offers a comprehensive suite of cloud-based security solutions designed to eliminate the attack surface and prevent data loss. Its Zero Trust Exchange™ platform helps enterprises securely connect users, devices, and applications regardless of location. SPLX, meanwhile, has gained recognition for its cutting-edge AI security solutions, including automated threat inspection, AI asset discovery, prompt hardening, and compliance tools that address the evolving risks associated with artificial intelligence.
The integration of SPLX’s technology introduces a new, dedicated layer of AI protection within Zscaler’s existing platform. This includes AI asset discovery and risk assessment tools covering models, code repositories, and Model Context Protocol (MCP) servers across both public and private environments. Automated AI red teaming capabilities will enable continuous testing and real-time remediation using over 5,000 purpose-built attack simulations. Zscaler will also enhance its AI Runtime Guardrails and prompt hardening to provide deep visibility into development environments, while expanding governance and compliance support for organisations aiming to proactively protect their AI infrastructure.
Zscaler CEO, chairman, and founder Jay Chaudhry said, “Today marks an important step in advancing Zscaler’s role as the trusted partner helping organizations securely adopt AI. AI is creating enormous value, but its full potential can only be realized when it can be secured. By combining SPLX’s technology with the intelligence of the Zscaler Zero Trust Exchange and its native data protection that classifies, governs, and prevents loss of sensitive data across prompts, models, and outputs, Zscaler will secure the entire AI lifecycle on one platform. This will strengthen our industry leadership and give customers the confidence to safely embrace AI.”
As AI continues to drive unprecedented infrastructure investments — projected to surpass $250bn by the end of 2025 — organisations face increasingly complex threats, from shadow AI sprawl to vulnerable large language models (LLMs). This acquisition positions Zscaler to offer end-to-end protection across every stage of AI adoption.
SPLX CEO and co-founder Kristian Kamber said, “Zscaler and SPLX share a vision to confront the vast new attack surface created by rapidly expanding AI infrastructure investments. 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 organizations are adopting it.”
