OWASP for AI Security
The OWASP GenAI Security Project publishes documents about security risks. This page covers two of them: the OWASP Top 10 for LLM Applications and the OWASP Top 10 for Agentic Applications. The OWASP Top 10 for LLM Applications is "a core initiative of the OWASP GenAI Security Project". The Agentic Security Initiative of the Project publishes the OWASP Top 10 for Agentic Applications. The OWASP Foundation announced the Agentic Security Initiative. The citation of the LLM Top 10 names the OWASP Foundation as the publisher.
The LLM Top 10 (2025 and 2026 editions) and Agentic Top 10 (2026) are community security guidance with the license CC BY-SA 4.0, not law.

This page gives general information. It is not legal advice or security advice. No endorsement, certification, or affiliation by the OWASP Foundation is claimed.
OWASP Top 10 for Large Language Model Applications
Security risks and mitigations for applications that use large language models.
OWASP Top 10 for Agentic Applications
Security risks and mitigations for AI agents.
When to use each OWASP Top 10
The OWASP Top 10 for LLM Applications gives security guidance for LLM applications and includes some agent risks. The Agentic Top 10 adds guidance when the system operates as an agent. A system that uses Retrieval-Augmented Generation (RAG) is not always agentic: see When to use the Agentic Top 10.

OWASP and AI governance frameworks
The OWASP LLM Top 10 2025 and Agentic Top 10 2026 do not map entries to ISO/IEC 42001 or EU AI Act articles. LLM04:2025 cites the NIST AI RMF as a related framework, without mappings to its Categories. The Agentic 2026 document has no mappings to those Categories. Appendix A of the LLM Top 10 2026 maps risks to NIST AI RMF Categories and other frameworks. See LLM mappings and Agentic mappings.
The GenAI Security Crosswalk is a different OWASP dataset that maps security risks to other frameworks. Its rule is: "Every mapping in this project is unreviewed until a named reviewer signs it."
Article 15 of the EU AI Act sets accuracy, robustness, and cybersecurity requirements for high-risk AI systems. Article 16(a) tells providers to "ensure that their high-risk AI systems are compliant with the requirements set out in Section 2". Article 15 applies from December 2, 2027 for Article 6(2) and Annex III systems, and August 2, 2028 for Article 6(1) and Annex I systems (Article 113(c)). For Article 6(1) systems related to Annex I Section B products, only Articles 6(1), 60a, and 102–112 apply, plus Articles 57–59 only insofar as the listed legislation incorporates high-risk requirements (Article 2(2)). See dates and transitional rules.
Other information from the OWASP GenAI Security Project
The OWASP GenAI Security Project publishes more than the two Top 10 documents. In the Letter from The Agentic Top 10 Leaders, the Agentic Security Initiative identifies these publications:
- "Agentic AI - Threats and Mitigations", the "core taxonomy" of the Agentic Security Initiative
- the "Agentic Threat Modelling Guide"
- "Securing Agentic Applications"
- "State of Agentic AI Security and Governance"
The OWASP GenAI Security Project also publishes the GenAI Security Crosswalk.
The OWASP AI Vulnerability Scoring System (AIVSS) is a different OWASP project. The OWASP Top 10 for Agentic Applications refers to AIVSS "for scoring and prioritization".
