Prisma AIRS

Prisma AIRS (AI Runtime Security) version 3.0, released in early 2026 by Palo Alto Networks, is a platform that spans the complete agentic AI lifecycle. It provides pre-deployment AI model and application discovery, runtime traffic inspection for AI APIs, and active defense against prompt injection, model manipulation, jailbreaking, and data exfiltration through AI pipelines. It integrates with Prisma Cloud and Cortex for unified security posture.

Installation

Prisma Cloud Integration (Primary Method)

# Install the AIRS CLI (requires Prisma Cloud access)
curl -sSL https://install.prismacloud.io/airs | bash

# Authenticate with Prisma Cloud tenant
airs login \
  --tenant your-tenant.prismacloud.io \
  --access-key $PRISMA_ACCESS_KEY \
  --secret-key $PRISMA_SECRET_KEY

# Verify connectivity
airs status

Kubernetes Admission Controller

# Add Palo Alto Helm repo
helm repo add paloalto https://helm.paloaltonetworks.com
helm repo update

# Install AIRS operator
helm install prisma-airs paloalto/prisma-airs \
  --namespace prisma-airs-system \
  --create-namespace \
  --set prismaCloud.apiUrl="https://api.prismacloud.io" \
  --set prismaCloud.accessKey="$PRISMA_ACCESS_KEY" \
  --set prismaCloud.secretKey="$PRISMA_SECRET_KEY" \
  --set runtime.interceptMode="enforce"   # enforce | detect | audit

# Verify operator
kubectl get pods -n prisma-airs-system

Sidecar Injection (per workload)

# Label namespace for automatic sidecar injection
kubectl label namespace ai-workloads prisma-airs-inject=enabled

airs discovery run

# 2. Create a policy profile for the application
airs policy create \
  --name "chatbot-v2-policy" \
  --template "customer-facing-llm" \
  --profile production

# 3. Label the application namespace for injection
kubectl label namespace chatbot-v2 prisma-airs-inject=enabled

# 4. Deploy application (sidecar auto-injected)
kubectl apply -f chatbot-v2/

# 5. Verify interception is active
airs status --namespace chatbot-v2

# 6. Run simulation to validate detection
airs simulate \
  --namespace chatbot-v2 \
  --attacks "prompt-injection,jailbreak" \
  --assert-blocked

Incident Investigation

# 1. List recent high-severity incidents
airs incidents list --severity high --last 24h

# 2. Get full context on an incident
airs incidents get INC-2026-00891 --include-payload

# 3. Check other incidents from the same source app
airs incidents list --source-app chatbot-v2 --last 7d

# 4. Block the offending session
airs sessions block --id sess-abc123 --reason "Active prompt injection"

# 5. Generate incident report
airs incidents report INC-2026-00891 --format pdf

# 6. Resolve and add notes
airs incidents resolve INC-2026-00891 \
  --resolution "Blocked session, updated injection patterns, notified app team"

Executive Reporting

# Generate weekly AI security posture report
airs report generate \
  --type executive \
  --period weekly \
  --include "incidents,inventory,compliance,trends" \
  --format pdf \
  --output ai-security-weekly.pdf

# Schedule automated reports
airs report schedule \
  --type executive \
  --cron "0 8 * * 1" \
  --email ciso@company.com,security-team@company.com

Tips and Best Practices

  • Start in detect mode before switching to enforce — review the audit log for false positives before blocking production traffic
  • Never enable includePayloads: true in logging in production unless actively debugging; LLM payloads often contain sensitive user data
  • Run airs simulate against every new AI application before going live to validate your policy catches common attack patterns
  • Use airs inventory drift weekly to catch unauthorized model changes — shadow AI adoption is a major risk vector in 2026
  • Set token volume thresholds conservatively and tune them up based on baseline; sudden spikes often indicate data exfiltration attempts
  • Integrate with Cortex XDR so AI security incidents appear in the same investigation workflow as endpoint and network incidents
  • Pin approved models using airs inventory approve and configure alertOnNewModel: true so new models require explicit review
  • Test custom injection patterns with airs test prompt before adding them to enforce-mode policies to avoid blocking legitimate traffic
  • Review airs policy audit monthly to identify patterns in allowed-but-suspicious traffic that may need new detection rules
  • Use namespace-level policy scoping rather than cluster-wide to allow different risk tolerances for internal vs. customer-facing AI apps
