Agent & Tool-Use Penetration Testing
An agent is a model that can act: query databases, send emails, read files, move money. That capability makes it the highest-value target in your AI stack, because a successful manipulation turns into a real action with real consequences. We enumerate everything your agent can do, test whether it can be made to do something it should not, and show you where to draw the lines.
What We Test
Excessive agency (OWASP LLM06): We inventory every tool, function, and API your agent can call, flag the ones that are too powerful for an AI to hold (raw SQL, shell, file access, payments), and demonstrate how they can be reached through manipulated input.
Vulnerable tool integrations: The functions an agent calls are backend code like any other, and we test them for the classic vulnerability classes: SQL injection, command injection, SSRF, and path traversal, confirmed safely and out-of-band.
Privilege confusion: We test whether low-privilege content can steer a high-privilege agent into sensitive actions, a pattern repeatedly proven in production systems.
Code execution paths: If your agent runs code it writes (a data-analysis tool, a Python interpreter), we carefully verify whether that path can lead to real code execution on your infrastructure.
Insecure output handling (OWASP LLM05): We verify whether your agent's output is safely handled wherever it is rendered or passed downstream, from chat UI to databases and internal APIs.
MCP security: For Model Context Protocol deployments, we review tool descriptions, authentication passthrough, and server configuration.
Why It Matters
Agents are given power to be useful, and power without strict limits is exactly what attackers look for. The fix is least privilege, confirmation for consequential actions, and treating every tool argument as untrusted input, and our report shows you precisely where yours falls short.
Deliverables
Agent capability map: Every tool, its reach, and its risk level.
Findings report: Mapped to the OWASP Top 10 for LLM Applications and MITRE ATLAS.
Hardening plan: Least privilege, approval flows, and output encoding that stop manipulation from becoming action.
