Services

Security testing for AI agents and the systems they can reach.

ModelStrike offers expert-led engagements covering AI agents, LLM applications, MCP integrations, and the architecture around them.

No two agent architectures are the same. Engagement scope, depth, and duration are set after we understand your system, its permissions, and what you need to demonstrate — internally or to customers.

AI Agent Security Assessment

A structured, hands-on assessment of your agent and everything it can reach. We map how instructions, data, and permissions flow through the system, then test where those boundaries break under adversarial pressure.

Good fit: Teams with an agent in, or close to, production who want a clear picture of real risk.

Typical coverage

  • Threat modeling
  • Attack surface mapping
  • Adversarial testing
  • Tool and permission review
  • Exploit validation
  • Remediation guidance

AI Agent Red Team

Goal-driven offensive testing that behaves like a motivated attacker. Rather than checking items off a list, we pursue realistic objectives — reaching data, triggering actions, escalating privileges — across the model, tools, and connected systems.

Good fit: Agents with broad tool access, sensitive data, or high-impact actions.

Typical coverage

  • Prompt injection
  • Indirect prompt injection
  • Privilege escalation
  • Tool abuse
  • Data extraction
  • Cross-system attack chains
  • Autonomous failure scenarios

Pre-Deployment Security Review

A focused review timed for launch or procurement. We assess the architecture and controls you plan to ship with, validate guardrails, and leave you with a prioritized plan and clearer answers for security questionnaires.

Good fit: Launches, major capability expansions, and enterprise security reviews.

Typical coverage

  • Architecture review
  • Production-risk analysis
  • Guardrail validation
  • Authorization review
  • Deployment recommendations
  • Prioritized remediation report

MCP Security Testing

MCP makes it easy to hand an agent new capabilities — and easy to hand over too much. We review the servers you build or depend on for exposed capabilities, authorization gaps, tool description manipulation, and unsafe handling of model-supplied input.

Good fit: Teams publishing MCP servers or connecting agents to internal or third-party MCP servers.

Typical coverage

  • Capability and scope review
  • Server authentication and authorization
  • Tool description and metadata manipulation
  • Input handling in tool implementations
  • Third-party server trust assessment

LLM Application Security

Not every LLM feature is a fully autonomous agent, but most still handle untrusted input and sensitive data. We test prompt handling, retrieval, output handling, and the application security around the model.

Good fit: Copilots, chat assistants, and retrieval-augmented features.

Typical coverage

  • Direct and indirect prompt injection
  • RAG and retrieval pipeline review
  • Sensitive data exposure
  • Insecure output handling
  • Tenant isolation

Architecture Threat Modeling

The cheapest time to fix an over-permissioned agent is before it ships. We work with your engineers to model trust boundaries, data flows, and high-impact actions, and recommend controls that fit your architecture.

Good fit: Teams designing a new agent or significantly expanding an existing one.

Typical coverage

  • Trust boundary and data flow mapping
  • Permission and least-privilege design
  • Human approval checkpoints
  • Logging and detection recommendations
  • Prioritized design recommendations
