Adversarial Testing forAI Systems, LLMs &Agentic Pipelines

Purpose-built penetration testing for AI applications — covering prompt injection, jailbreaking, RAG poisoning, MCP tool abuse, and autonomous agent exploitation across your entire AI attack surface.

Service Overview

AI attack surface
coverage intel

AI systems expose fundamentally different attack primitives than traditional software. Where conventional tools target syntax and protocol boundaries, AI vulnerabilities live in semantic space — within the meaning, context, and intent of language itself.

The AI Security Gap

Traditional pentest
tools don't
speak AI.

Conventional security tooling was built for APIs, web apps, and networks. The AI stack adds 6 new layers above infrastructure — each with novel attack primitives that traditional scanners cannot model or detect.

MCP Security Testing

Model Context Protocol is
the new attack vector.

MCP gives AI models the ability to call tools, read files, query databases, and invoke APIs. Any successful prompt injection can now trigger real-world actions with catastrophic, irreversible consequences across your enterprise infrastructure.

👤User🧠LLM⚙️MCP Router📁File System🌐External API🗄️Database
What We Test
MCP Server Security Review
Audit authentication, transport, and server configuration for weaknesses.
Tool Schema Attack Testing
Fuzz and enumerate all exposed tool definitions for abuse potential.
Cross-Tool Injection Chains
Test adversarial content propagation across chained tool invocations.
Privilege Boundary Validation
Verify that AI tool access cannot exceed intended permission scopes.
Rogue MCP Server Simulation
Simulate malicious MCP servers to test client-side trust validation.

Unauthorized Tool Invocation

CRITICAL

Prompt injection triggers unintended tool calls — file reads, API requests, database queries — executing real-world actions without authorization.

CVSS 9.1CWE-862

Privilege Escalation via Tools

CRITICAL

Chained MCP tool calls enable lateral movement from low-privilege AI context to high-privilege system access across connected integrations.

CVSS 8.8CWE-269

Tool Schema Enumeration

HIGH

Exposed MCP tool schemas reveal system capabilities, identify overprivileged functions, and enable crafted targeted abuse payloads.

CVSS 6.5CWE-200

Data Exfiltration via MCP

HIGH

Adversarial prompts direct the AI to leverage MCP file and API tools to silently exfiltrate sensitive data to attacker-controlled endpoints.

CVSS 7.6CWE-200

MCP Server Impersonation

HIGH

Rogue MCP servers present malicious tool definitions to the AI client, hijacking execution flow and intercepting sensitive authentication data.

CVSS 7.2CWE-290

Cross-Tool Injection

MEDIUM

Adversarial content embedded in tool outputs corrupts subsequent LLM reasoning, creating chained injection attacks across tool invocations.

CVSS 5.4CWE-74
