SPLX, founded in Croatia in 2023, built software that tests, protects, and governs enterprise AI systems: it discovers AI models, workflows, and MCP connections into a single inventory called an AI bill of materials, runs automated attacks to surface weaknesses, and adds guardrails that block attacks in production. On about nine million dollars raised it reached named customers including KPMG, Infobip, and Glean, then Zscaler acquired it in November 2025 to add its AI asset discovery, red teaming, and governance to the Zero Trust Exchange, while SPLX still ships as a standalone platform. The fast acquisition is the strongest outcome signal in the reviewed record, though the undisclosed terms prevent assessing the financial outcome.
