An agent that can read email, query databases and call APIs is a new attack surface. We red-team your LLM apps and agents the way an attacker would, then fix what we find: permissions, guardrails, isolation and evals that keep it fixed.
Any text an agent reads (a web page, an email, a PDF, a ticket) can carry instructions. Combine that with tool access and you get data exfiltration, unauthorized actions and leaked system prompts. Most teams ship agents without ever testing for it.
- 01
LLM app & agent red teaming
Direct and indirect prompt injection, jailbreaks, system-prompt extraction, tool abuse and cross-tenant leakage, tested against your real deployment.
- 02
Agent permission review
Every tool, credential and scope your agents hold, mapped against what they actually need. Least privilege, enforced.
- 03
RAG & data-leak testing
Can a user retrieve documents they shouldn't? Can a poisoned document steer answers? We find out.
- 04
Guardrails & regression evals
Input/output filters, policy checks and an attack eval suite that runs on every release, so fixed stays fixed.

Your competitor's agent is working right now.
Get my agent nowIs this a pentest?
It's a focused, authorized security assessment of your AI layer: models, prompts, retrieval, tools and agent permissions. We can combine it with a classic web/API assessment.
Do you need production access?
We prefer a staging copy with realistic data and tools. Every engagement is scoped and authorized in writing before testing starts.
Can prompt injection be fully prevented?
Not with filters alone. The durable fixes are architectural: least-privilege tools, isolation of untrusted content, human approval on sensitive actions and monitoring. We design for that.
We built our agent with a vendor platform. Can you still test it?
Yes. We test the deployed behavior and configuration, whatever framework or platform sits underneath.
