SPLX is a commercial platform for red teaming AI systems, now part of Zscaler. Its AI Red Teaming product, called Probe, runs automated tests that use generative AI to craft attacks against a target application, drawing on an attack database and the customer's own datasets. The docs describe a customizable set of probes, a compliance view that includes the OWASP LLM Top 10 2025, a PDF report for each test run and remediation help such as prompt hardening. SPLX also sells runtime protection and publishes Agentic Radar, a free open-source scanner for agent workflows, which is a separate product. The pricing page shows plan names and credits but no prices, and quotes come through sales.
