Palo Alto Prisma AIRS: End-to-End Security for Your AI Ecosystem

Palo Alto Prisma AIRS is an AI security platform that lets organisations discover, assess and protect their AI applications, models, agents and the data they use, all from a single platform. As generative AI and agentic applications move quickly into business processes, security teams face a new question: which AI applications are running, what data do they reach, and what are they allowed to do?

Why Does AI Need a New Security Approach?

AI applications are exposed to attacks that traditional security tools do not recognise. Prompt injection can hijack a model's instructions, sensitive data can leak through model responses, and models downloaded from third-party sources can carry tampered files or malicious scripts. AI agents that can call tools and take actions on their own open a new door for unauthorised activity. These risks call for a layer of visibility and protection built specifically for AI.

Core Components of Prisma AIRS

AI Gateway: The control plane that discovers, governs and secures every AI activity in the enterprise, making it clear which teams use which AI services.

AI Model Security: Scans third-party models before they are used, detecting tampered model files, malicious scripts and deserialization attacks.

AI Red Teaming: Simulates real-world attacks to uncover weaknesses in AI applications and agents before attackers do.

AI Posture Management: Provides visibility and control over training and inference data, model access and the integrity of applications and agents, so misconfigurations and excessive permissions are caught early.

Agent Security: Verifies agent identity and blocks unauthorised actions at scale with real-time security policies.

AI Runtime Security: Monitors AI behaviour at runtime and stops manipulation, data exposure and unsafe actions with real-time safeguards.

Flexible Deployment

Prisma AIRS can be deployed in two ways: inline on network traffic without changing applications (Network Intercept), or integrated directly into applications through an API (API Intercept). AI applications, LLM deployments, models, cloud infrastructure and containers are protected under the same policy framework. Palo Alto Networks also offers Managed AI Runtime Security as a managed option.

Protection That Reaches the Endpoint: Koi

The Agentic Endpoint Security technology of Koi, whose acquisition Palo Alto Networks completed in April 2026, extends Prisma AIRS to the AI agents, MCP servers and extensions running on employees' computers. AI security no longer stops at the cloud and the data centre; it becomes a single control plane across the enterprise.
