The OWASP Top 10 for Large Language Models (LLMs) is a security framework that identifies the most critical risks affecting AI systems. These risks focus on how AI models interpret input, interact with enterprise systems, and process sensitive data at runtime.
Unlike traditional software security risks, LLM risks emerge from the model’s dynamic inference behavior and system integration pathways. These risks include prompt injection, sensitive data exposure, unauthorized system interaction, and governance visibility gaps.
According to OWASP, these risks represent structural vulnerabilities in AI systems that cannot be mitigated using traditional infrastructure security controls alone.
As enterprises deploy AI agents, copilots, and automated workflows powered by LLMs, the OWASP Top 10 provides a critical framework for understanding and securing enterprise AI deployments.
Securing enterprise AI systems requires runtime visibility into agent behavior, system interaction, and execution pathways.
What Is the OWASP Top 10 for LLMs?
The OWASP Top 10 for LLMs is a security framework developed to identify the most critical risks affecting AI systems that use large language models. It provides a structured taxonomy of vulnerabilities specific to AI inference behavior, agent execution, and system integration.
The framework was created to address security challenges introduced by the widespread deployment of AI agents, enterprise copilots, and automated AI driven workflows. Traditional security frameworks focus on software vulnerabilities such as injection flaws, authentication failures, and infrastructure compromise. The OWASP LLM Top 10 focuses on risks unique to AI systems.
These risks emerge from how LLMs interpret instructions, interact with enterprise systems, and process sensitive data dynamically at runtime.
The OWASP Top 10 for LLMs serves several critical enterprise purposes:
Why OWASP LLM Risks Matter for Enterprise AI Security?
Enterprise AI systems differ fundamentally from traditional software systems. AI agents dynamically interpret instructions, retrieve enterprise data, and execute system actions at runtime. This dynamic execution model introduces security risks that traditional software security frameworks do not address.
AI agents frequently interact with enterprise systems such as APIs, databases, and internal services. These interactions create pathways through which malicious input can influence system behavior, retrieve sensitive data, or execute unauthorized actions.
Unlike traditional cyberattacks, many AI security risks do not involve exploiting software vulnerabilities. Instead, they manipulate the model’s interpretation process and runtime execution logic.
The enterprise impact of OWASP LLM risks includes:
Overview of the OWASP Top 10 LLM Risks
The OWASP Top 10 for Large Language Models provides a structured taxonomy of the most critical risks affecting enterprise AI systems. These risks focus on vulnerabilities that emerge from runtime inference, system integration, and agent driven execution rather than traditional infrastructure compromise.
These risks reflect how AI systems operate differently from traditional software systems. Because AI agents dynamically interpret input and interact with enterprise systems, vulnerabilities emerge at the runtime execution layer. Unlike traditional application security risks, many OWASP LLM risks involve manipulation of model behavior rather than exploitation of software flaws.
The OWASP Top 10 LLM risks are summarized below:
Key Enterprise Risks Explained
While all OWASP LLM risks are important, several risks have particularly significant impact on enterprise AI deployments. These risks directly affect system integrity, data protection, and operational security.
The most critical enterprise risks include prompt injection, sensitive data exposure, insecure tool integration, and excessive agent permissions.
1. Prompt Injection (LLM01): Runtime Manipulation of AI Agent Behavior
Prompt injection is the most critical risk affecting enterprise AI systems. It allows attackers to manipulate agent behavior by providing malicious instructions that influence runtime execution.
This can result in:
- Retrieval of sensitive enterprise data
- Execution of unauthorized system actions
- Manipulation of automated workflows
Prompt injection targets the inference layer rather than infrastructure, making it difficult to detect using traditional security tools.
This risk was covered in detail in the Direct and Indirect Prompt Injection articles.
2. Sensitive Information Disclosure (LLM06): Exposure of Confidential Enterprise Data
AI agents frequently retrieve and process enterprise data. Without proper governance, agents may expose sensitive information through model output or system interaction.
This may include:
- Customer data
- Intellectual property
- Credentials and configuration data
Sensitive data exposure creates regulatory, operational, and reputational risk.
3. Insecure Plugin and Tool Integration (LLM07): Unsafe MCP and API Interaction
AI agents interact with enterprise systems through tools, plugins, and MCP Server integrations. If these integrations are improperly governed, agents may execute unsafe system actions.
This may result in:
- Unauthorized API access
- Unsafe system execution
- Exposure of enterprise infrastructure
Because MCP Servers govern tool interaction, securing MCP execution is critical for enterprise AI security.
4. Excessive Agency (LLM08): Over Permissive Agent System Access
Excessive agency occurs when AI agents are granted broad system access without sufficient governance. This allows agents to retrieve data or execute actions beyond intended scope. If agent behavior is manipulated, excessive privileges may result in widespread system exposure.
This risk highlights the importance of enforcing runtime governance and access controls.
The highest impact enterprise AI risks can be summarized as follows:
Why Traditional Security Tools Cannot Address OWASP LLM Risks
Traditional enterprise security tools are designed to protect infrastructure, applications, and network communication. These tools rely on predefined execution logic, static access controls, and known system interaction pathways. Large Language Models and AI agents operate differently. They interpret instructions dynamically and execute actions at runtime based on inferred intent rather than predefined logic.
Because OWASP LLM risks emerge from runtime inference and agent driven execution, traditional security tools cannot fully govern or detect these threats.
This creates a security gap between infrastructure level protection and AI runtime execution.
1. Infrastructure Security Tools Cannot Govern AI Runtime Behavior
Infrastructure security tools monitor system access, authentication events, and network communication. They verify whether access is authorized but cannot determine whether AI driven execution is safe or appropriate.
AI agents may operate using valid credentials and authorized system access. However, adversarial instructions can manipulate agent behavior and cause unsafe execution.
Infrastructure security tools cannot detect whether agent driven system interaction has been influenced by malicious input.
2. API Gateways Cannot Interpret Agent Intent or Execution Logic
API gateways enforce authentication, authorization, and request validation. They ensure that only authorized entities access enterprise systems. However, API gateways cannot interpret why an AI agent generates a request. If an agent executes a request influenced by prompt injection or adversarial content, the API gateway cannot distinguish it from legitimate execution.
This creates a governance gap between access control and execution safety.
3. Identity and Access Management Cannot Prevent Instruction Manipulation
Identity and access management systems enforce access permissions. These systems ensure that agents or applications can access only authorized systems. However, identity controls cannot prevent misuse of authorized access. AI agents may retrieve sensitive data or execute unsafe workflows if manipulated through adversarial input.
This risk emerges from execution behavior rather than access authorization.
4. Application Security Tools Cannot Monitor Inference Layer Execution
Traditional application security tools analyze application code and predefined execution pathways. AI agents do not follow fixed execution logic. Their behavior is determined dynamically through model inference.
Because prompt injection and related risks target the inference layer, traditional application security tools cannot observe or detect these attacks.
They cannot monitor:
- Model instruction interpretation
- Agent reasoning pathways
- Runtime execution decisions
This makes AI specific threats invisible to conventional application security analysis.
The limitations of traditional security tools in addressing OWASP LLM risks can be summarized as follows:
