AI Agent Security
OWASP Agentic AI, EU AI Act enforcement, and production guardrails
AI security transformed in 2026. OWASP released a dedicated Top 10 for Agentic Applications — distinct from the LLM Top 10 — because autonomous agents introduce fundamentally new risks. The EU AI Act is now actively enforced, with the first investigation launched into Grok. Lakera was acquired by Check Point for ~$300M, validating the market. The "Intent Capsule" pattern is becoming mandatory for serious agent deployments.

OWASP Top 10 for Agentic Applications (2026)
OWASP released a new Top 10 specifically for agentic AI — separate from the LLM Top 10 — because agents that plan, persist, and delegate across tools create fundamentally different risks than single-model content generation. Developed with 100+ industry experts.
Prompt Injection
#1 Risk#1 attack vector. "Intent Capsule" pattern is the mandatory defense — separate system instructions from user input.
Tool Misuse
CriticalAgents accessing resources beyond scope. Requires explicit tool permission systems and sandboxing.
Delegation Attacks
New in 2026Manipulating agent delegation chains. Multi-agent systems amplify this risk.
Persistent State Manipulation
EmergingPoisoning agent memory/context across sessions. Long-running agents are vulnerable.
Regulatory Landscape (February 2026)
Three regulatory frameworks are reshaping AI development. The EU AI Act is now actively enforced with the first investigation launched. California SB 53 mandates transparency from frontier AI developers. HIPAA is evolving to require bias auditing.
EU AI Act
EnforcingActive enforcement since Feb 2025 (bans), Aug 2025 (GPAI rules). First investigation into Grok. Full compliance Aug 2026.
California SB 53
ActiveFrontier AI developers (>$500M revenue) must disclose safety testing, third-party audits, and standards.
California SB 243
ActiveAI watermarking mandate for synthetic content. C2PA standard adoption accelerating.
HIPAA AI
HealthcareCovered entities must audit AI for bias, document training data, maintain accuracy metrics.
Defense-in-Depth Architecture
Production AI security requires four layers. The "Intent Capsule" pattern — treating all user inputs as untrusted and routing through rigorous validation — is the mandatory architectural requirement. A "no" from a guardrail is final.
Input Validation
Layer 1Intent Capsule pattern, prompt classification, injection detection. Treat all inputs as untrusted.
Execution Guardrails
Layer 2Tool permissions, rate limiting, sandboxing. Guardrail "no" is final — no override.
Output Filtering
Layer 3PII detection, content safety, compliance checks, C2PA watermarking.
Audit & Monitoring
Layer 4Decision tracing, anomaly detection, compliance reporting, human-in-the-loop triggers.
AI Security Market & Platforms
The AI cybersecurity market was valued at $22.4B in 2023, growing at 21.9% CAGR. Check Point acquired Lakera for ~$300M, validating AI-native security as a critical enterprise need. Guardrails platforms are becoming standard production components.
Lakera (Check Point)
$300MAcquired ~$300M. Real-time GenAI security. Prompt injection detection, output scanning.
NVIDIA NeMo Guardrails
Open SourceOpen-source guardrails framework. Programmable safety rails for LLM applications.
Pangea
API-FirstSecurity APIs for AI applications. Authentication, authorization, audit logging.

Frequently Asked Questions
Prompt injection is the most common attack vector — adversarial inputs that override agent instructions to hijack behavior.
