SplxAI, the fast-rising Croatian-founded company specializing in securing AI applications and large language models (LLMs), has been acquired by cloud security behemoth Zscaler, Inc. for an undisclosed amount. The acquisition marks a significant milestone for the young startup, which has rapidly established itself as in a critical, emerging AI cybersecurity niche.
The deal, announced Monday, centers on integrating SplxAI’s technology into Zscaler’s Zero Trust Exchange platform. For SplxAI, the move represents a massive acceleration of its core mission to protect the AI-driven enterprise.
“Our mission is to re-define how security leaders and AI practitioners test their AI applications and agentic workflows,” said Kristian Kamber, CEO & Co-founder of SplxAI, earlier this year. Following the acquisition, Kamber expressed enthusiasm for the new chapter, stating that joining Zscaler will allow the company to bring its innovation to “one of the most trusted security platforms in the world.”
From Seed to Acquisition in under a year
Founded in 2024 by Kristian Kamber and Ante Gojsalić, SplxAI was created to address the “significant security gaps” appearing as businesses adopted AI chatbots and agentic workflows at scale. The company’s flagship platform, Probe, was designed to proactively detect and mitigate vulnerabilities in these systems before malicious actors could exploit them.
SplxAI’s innovative approach quickly drew investor attention. In March 2025, the company announced a successful $7 million (€6.49 million) seed funding round, led by LAUNCHub Ventures with participation from Rain Capital, Inovo, Runtime Ventures, DNV Ventures, and South Central Ventures. This funding was intended to fuel the advancement and adoption of the SplxAI Platform, which was already reporting impressive traction.
“AI agents have the potential to re-define the business landscape, but as their adoption increases, so does the potential for abuse,” stated Stan Sirakov, General Partner at LAUNCHub Ventures, during the seed round announcement. He highlighted SplxAI as the “only vendor with a plan for managing this risk at scale.”
Evidence of the company’s market momentum was clear, with SplxAI reporting 127% quarter-over-quarter growth since launching its platform in August 2024, securing high-profile customers including KPMG, Infobip, and Glean.
SplxAI’s technology in spotlight
The centerpiece of the acquisition is SplxAI’s comprehensive suite of AI security capabilities and SPLX’s deep expertise in AI red teaming, asset management, threat inspection, prompt hardening and governance. Those will expand Zscaler’s current capabilities, creating a new, dedicated and natively integrated layer of AI protection within the Zscaler Zero Trust Exchange platform. As per Zscaler’s press announcement, that includes:
-
- AI Asset Discovery across public and private deployments.
- Automated Red Teaming that can execute over 5,000 attack simulations against AI models.
- Runtime Guardrails for protecting sensitive data.
- Compliance Tools for AI governance.
Zscaler’s expanded platform will now offer protection for the entire AI lifecycle, including development environments, production systems, and the data flowing between AI applications.
According to a market analysis report by The CyberEdge Group, SplxAI’s technology was a highly sought-after strategic asset. The report noted that the startup had developed a “unique, full-lifecycle security paradigm” for generative AI, making it the ideal partner for a major cloud security platform looking to dominate the burgeoning AI security market.
