Palo Alto Networks Prisma AIRS Review 2026

Prisma AIRS is an AI runtime security platform from Palo Alto Networks designed to protect AI applications, agents, models, and data across the AI application lifecycle.

Prisma AIRS (AI Runtime Security) is Palo Alto Networks' enterprise-grade security platform purpose-built to defend organizations against the new and rapidly expanding category of AI-related threats. As enterprises rush to adopt large language models, generative AI tools, custom AI applications, and increasingly autonomous AI agents, the attack surface expands dramatically — exposing organizations to prompt injection, data leakage, model theft, training data poisoning, supply chain risks in third-party models, and unsafe agent behavior. Prisma AIRS aims to provide a unified, end-to-end control plane for managing these risks across the entire AI application lifecycle, from development through deployment and ongoing runtime operation.

The platform integrates several core capabilities into a single offering. AI Model Scanning inspects models — including those pulled from public hubs like Hugging Face — for malicious code, backdoors, deserialization exploits, and other supply-chain risks before they enter production. Posture Management gives security teams visibility into AI assets across the environment, surfacing misconfigurations, excessive permissions, and risky data exposures across model endpoints, vector databases, and AI services. AI Red Teaming continuously probes deployed AI applications and agents with adversarial techniques, simulating prompt injection, jailbreaks, and data exfiltration attempts to uncover weaknesses before attackers do. Runtime Security inspects prompts and responses in real time to block prompt injection, sensitive data leakage, malicious URLs, and policy violations as they occur. AI Agent Security extends protection to agentic workflows, governing tool use, identity, and autonomous decision-making to prevent agents from taking unsafe or unauthorized actions.
