2023SPLX provides an AI security platform that tests, protects, and governs enterprise AI systems across their lifecycle.
The SPLX Platform is an enterprise AI security service that tests, protects, and governs AI systems across their lifecycle. Its capabilities span automated AI red teaming, AI asset discovery and risk assessment, real-time runtime threat detection and response, prompt hardening and dynamic remediation, and governance and compliance mapping.
A threat inspection capability scans large language model logs for jailbreaks, prompt injections, and malicious queries, and an AI model security service stress-tests commercial and open-source models. The platform is delivered as a subscription with free, professional, and enterprise tiers, and is now integrated within the Zscaler Zero Trust Exchange.
Enterprise AI adoption is expanding the attack surface faster than manual testing can cover, driving demand for continuous, automated AI security spanning discovery, testing, runtime protection, and governance. Regulatory pressure on AI systems is simultaneously making compliance mapping a standing requirement rather than a one-off audit task.
SPLX's November 2025 acquisition by Zscaler places its red teaming and runtime protection capabilities inside the Zero Trust Exchange, aiming to deliver full-lifecycle AI security at the scale of Zscaler's enterprise customer base. The category remains contested, with both specialist vendors and broad platform vendors adding AI security offerings.
SPLX positions itself as an end-to-end platform rather than a point tool: automated red teaming, AI asset discovery, runtime guardrails, dynamic remediation, and compliance mapping operate from a single control point. Its attack simulation draws on an extensive AI attack database plus customer datasets, and its Policy Generator turns red-team findings into deployable guardrail policies.
The company was built by AI security practitioners and red teamers, publishes primary research on frontier-model vulnerabilities, and maintains Agentic Radar, an open-source scanner for agentic workflows. Fortune 500 and global enterprise customers are cited as reference buyers.
As a younger company founded in 2023, SPLX entered a crowded AI security market alongside more established vendors with larger footprints and longer enterprise track records.
Its platform is now integrated within the Zscaler Zero Trust Exchange, which narrows its independent go-to-market surface relative to standalone AI security specialists that sell across multiple cloud and security platforms.
