Protect AI vs SplxAI

Both compete in Red-Teaming & AI Security. Protect AI positions itself as “End-to-end security for the AI and machine-learning supply chain”, while SplxAIleads with “End-to-end security for AI with automated red teaming and runtime protection for agentic systems”. The table below compares what each publishes.

Where Protect AI pulls ahead

Publishes support for NIST AI RMF, SOC 2, which SplxAI does not. Security and ML teams needing to scan and defend models, pipelines, and LLM apps across the AI lifecycle

Best forSecurity and ML teams needing to scan and defend models, pipelines, and LLM apps across the AI lifecycleEnterprises wanting full-stack AI security from red teaming through runtime protection for agentic systems
LimitationsNow integrated into Palo Alto Networks, so standalone products may converge into Prisma AIRS; breadth means some components (runtime guardrails vs. model scanning) are stronger than othersNow part of Zscaler, so standalone availability and roadmap are tied to the acquirer; detailed compliance certifications not publicly enumerated.

Which should you shortlist?

Choose Protect AI if security and ML teams needing to scan and defend models, pipelines, and LLM apps across the AI lifecycle

Choose SplxAI if enterprises wanting full-stack AI security from red teaming through runtime protection for agentic systems

Neither is a substitute for a governance program. Whichever you pick, you still need people who can define the policies the tool enforces.
