No free plan. The cheapest way in is Enterprise at Custom (contact sales). Consider free alternatives in the enterprise agents category if budget is tight.
Prisma AIRS is designed to defend against AI-specific threats including prompt injection, jailbreaks, sensitive data leakage through LLM responses, malicious or backdoored models, model and training data poisoning, insecure AI agent tool use, and misconfigurations across AI infrastructure.
Traditional WAFs and DLP tools were not built to understand LLM prompts, embeddings, or agent behavior. Prisma AIRS adds AI-aware inspection of prompts and responses, model scanning, AI posture management, and agent governance — controls that general-purpose security tools typically lack.
Yes. Prisma AIRS includes model scanning for models from sources such as Hugging Face and supports protection of AI applications built on a range of commercial and open-source LLMs, including those deployed in cloud and self-hosted environments.
It targets enterprises and regulated organizations building or deploying AI applications and agents at scale — particularly those that already use Palo Alto Networks security products and need centralized governance, compliance, and runtime protection across AI workloads.
Prisma AIRS is sold as an enterprise offering through Palo Alto Networks sales and partners. Pricing is not published publicly and is typically structured around organization size, deployment scope, and the specific modules required.
