Cloud security giant Zscaler on Monday announced the acquisition of AI security company SPLX.
Founded in 2023, SPLX has developed solutions designed to secure AI chatbots, agents, models, and workflows.
The company provides AI asset discovery and risk assessment, and automated AI red teaming and vulnerability remediation capabilities. It also offers runtime guardrail, threat inspection, prompt hardening, and governance solutions.
SPLX expertise and technology enables Zscaler to expand the capabilities of its Zero Trust Exchange platform.
Financial terms of the deal were not disclosed.
SPLX (also known as SplxAI) has raised $9 million in funding, including $7 million in a seed round announced in March 2025.
“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,” said Jay Chaudhry, CEO and founder of Zscaler.
Zscaler in recent years also acquired Red Canary for $675 million, Avalor for $350 million, and AirGap.
More than 360 mergers and acquisitions have been added this year to SecurityWeek’s cybersecurity M&A tracker.
Nine of those deals involved the acquisition of companies specializing in artificial intelligence security. A majority of these acquisitions were made by large firms looking to enhance and extend their AI security capabilities. The list includes Tenable, SentinelOne, Check Point, and CrowdStrike.
