Protect AI vs Giskard

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 Giskardleads with “Open-source and enterprise platform for testing and red-teaming LLM agents”. The table below compares what each publishes.

Where Protect AI pulls ahead

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

Where Giskard pulls ahead

Publishes support for EU AI Act, which Protect AI does not. ML, quality, and risk teams wanting open-source-first, framework-aligned LLM testing and continuous red teaming

Both map to NIST AI RMF, so framework coverage alone will not separate them — the decision usually comes down to who operates the tool and how it fits your existing stack.

Best forSecurity and ML teams needing to scan and defend models, pipelines, and LLM apps across the AI lifecycleML, quality, and risk teams wanting open-source-first, framework-aligned LLM testing and continuous red teaming
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 othersTesting/evaluation focus rather than inline runtime enforcement; smaller company and funding base; enterprise features concentrated in the paid Hub tier

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 Giskard if mL, quality, and risk teams wanting open-source-first, framework-aligned LLM testing and continuous red teaming

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