Zscaler, Inc. has reinforced its commitment to AI security by acquiring SPLX, a prominent AI security innovator. This strategic acquisition aims to advance the Zscaler Zero Trust Exchange platform, integrating enhanced asset discovery, red teaming capabilities, and robust governance frameworks.

With this move, Zscaler positions itself as the trusted partner for organisations striving to securely harness AI's potential. According to Jay Chaudhry, CEO of Zscaler, securing AI's full value necessitates comprehensive protection across the entire AI lifecycle, a goal that this acquisition aims to achieve.

The escalation of AI investments, projected to surpass $250 billion by 2025, underscores the urgency for improved security measures. Organisations now face an expanding attack surface, necessitating continuous discovery and risk assessment across evolving models and infrastructures.

SPLX brings to the table expertise in AI asset management and threat mitigation, enriching Zscaler's existing capabilities. Its technology will natively integrate within the Zscaler Zero Trust Exchange platform to offer seamless AI protection. Key features include:

  • AI Asset Discovery and Risk Assessment: Encompassing public and private AI deployments, from models to MCP servers.
  • Automated AI Red Teaming: Offering over 5,000 specialised attack simulations.
  • AI Runtime Guardrails: Enhancing data protection across AI applications and LLMs.
  • Governance and Compliance: Proactively ensuring adherence to governance frameworks.

Moreover, Kristian Kamber, CEO of SPLX, shares an aligned vision with Zscaler, stating the collaboration aims to address the challenges posed by rapidly growing AI infrastructure investments.

While forward-looking statements affirm the acquisition's potential benefits, they remain subject to certain risks and uncertainties as outlined in regulatory filings. Emphasis is placed on the seamless integration of SPLX’s technology into Zscaler's platform alongside preserving SPLX’s business continuity.

This acquisition underscores Zscaler’s pursuit of AI innovation security, ensuring it continues to shield valuable AI investments in an increasingly digitised landscape.
