AI and LLM Penetration Testing

AI Penetration Testing Services for LLMs and Agents

Manual penetration testing for LLM applications, RAG pipelines, and agents. Assess prompt injection, sensitive data exposure, and tool abuse across your AI application.

Brain

What every AI and LLM pentest includes

  • OWASP LLM risk coverage
  • Prompt injection and jailbreak testing
  • System prompt and sensitive data exposure
  • Agent permission and tool use abuse
  • RAG retrieval and poisoning risks
  • Direct access to the researchers on your engagement
  • Fix validation when included in scope

What is AI penetration testing?

AI penetration testing examines how attackers could exploit prompts, retrieved content, agents, and connected tools. Blaze tests these paths alongside the application’s access controls, APIs, and data flows.

What AI penetration testing services cover

AI-specific attack paths that conventional application testing may not cover.

In scope

Prompt injection

Direct and indirect prompt injection in user and retrieved content.

In scope

Data leakage

Exposure of system prompts, confidential data, or retrieved content.

In scope

Guardrail bypass

Bypassing safety controls, context handling, or output validation.

In scope

Unsafe output handling

Untrusted model output reaching browsers, APIs, tools, or interpreters.

In scope

Excessive agency

Over-privileged agents taking unintended or unauthorized actions.

In scope

Model denial of service

Inputs causing excessive resource use or service degradation.

In scope

Retrieval manipulation

Manipulating retrieved content to influence model behavior.

In scope

Supply chain

Risks in models, tools, plugins, and dependencies.

Our Process

Our testing methodology

Map the architecture, test AI-specific attack paths, and validate how weaknesses connect across the application.

01

Architecture review

Map AI/LLM integration points, data flows, model access, trust boundaries

02

Prompt injection testing

Direct and indirect prompt injection across all input vectors

03

Data leakage assessment

Assess system prompts, confidential data, PII, and connected data.

04

Guardrail bypass testing

Probe content filters, safety controls, and output handling

05

Agent and tool security

Test tool permissions, action authorization, and multi-step attacks.

06

Reporting and remediation

Findings with reproduction steps, risk ratings, and clear fixes

Test how your AI handles untrusted input

Assess how prompts and retrieved content interact with your application’s data, permissions, and tools.

Warning

Prompt injection through retrieved content

Test whether instructions hidden in retrieved documents can redirect application behavior, expose sensitive data, or trigger unintended tool actions.

Warning

Agent permissions and tool abuse

Test whether an agent can access data or execute tool actions beyond the requesting user’s permissions.

Frequently asked questions

Answers about AI application scope, models, RAG, agents, tools, safety limits, pricing, and remediation.

Pricing depends on the models, applications, RAG pipelines, agents, tools, data sources, user roles, environments, and testing depth. Share the architecture and objectives for a fixed scope and quote.
Blaze tests chatbots, copilots, RAG applications, content-generation systems, AI search, and agents that call external tools. Scope can include hosted or self-managed models and the surrounding application.
AI testing covers prompt injection, retrieval manipulation, data leakage, unsafe output handling, and excessive agency. Web testing covers the surrounding application; weaknesses can chain across both layers.
Yes. Coverage can reference the OWASP Top 10 for LLM Applications alongside MITRE ATLAS and NIST AI RMF, adapted to the actual system.
Yes. Blaze assesses tool permissions, action authorization, context handling, data access, and multi-step paths that could trigger unintended actions.
Testing follows agreed environments, accounts, rate limits, sensitive actions, data-handling rules, and safety limits. Potentially disruptive actions require explicit approval.
Not always. A pentest focuses on exploitable security risks in a defined system. AI red teaming may also examine misuse, safety, resilience, or broader adversarial behavior.
Not always. Black-box testing can assess exposed behavior; architecture, prompt, configuration, or source access can support deeper testing when appropriate.
Retest after fixes or material changes to models, prompts, retrieval data, integrations, tool permissions, or guardrails. The cadence should reflect the system's risk and rate of change.
