Solutions / LLM & AI agents

LLM red teaming for AI applications and agents.

Chatbots, copilots and autonomous agents add an attack surface that traditional testing does not cover. Cyrion’s AI Red Team probes how your model, prompts, tools and data sources behave under adversarial input.

Attacker-style recon

Agents build a model of your target before testing it, instead of sweeping it with signatures.

Chains, not lists

Individually minor weaknesses are combined into end-to-end attack paths.

Validated findings

A second agent re-attempts each issue in a sandbox before it reaches your report.

Audit-ready output

Reproduction steps, request logs and framework mappings in every report.

01 · Coverage

What the agents
test.

Every module shares one memory of your environment, so a finding on llm & ai agents fuels hypotheses on the next surface.

CAP-01

Prompt injection

Direct and indirect, including payloads hidden in retrieved documents and web pages.

CAP-02

Jailbreaks

System-prompt extraction and guardrail bypass.

CAP-03

Data leakage

Sensitive data exposed from context windows, RAG indexes and logs.

CAP-04

Excessive agency

Tools and actions an agent can be tricked into taking.

CAP-05

Insecure output handling

Model output that reaches a browser, shell or database.

CAP-06

Governance mapping

OWASP LLM Top 10, NIST AI RMF and EU AI Act obligations.

02 · ATTACK PATH

From a poisoned document to a tool call.

The risk is rarely the model alone. It is what the model can reach once an attacker controls its input.

03 · Method

How an engagement
runs.

The same loop a human red team follows, recon, hypothesis, exploit and debrief, running continuously instead of once a year.

01
Map

Catalogue the prompts, tools, retrieval sources and output sinks of your AI application.

02
Hypothesize

Plan direct and indirect injection, extraction and tool-abuse attacks.

03
Prove

Run adversarial inputs and confirm what the model leaks or does.

04
Report

Findings mapped to the OWASP Top 10 for LLMs and the NIST AI RMF.

Frameworks

Findings map to the OWASP Top 10 for LLM Applications, the NIST AI Risk Management Framework and EU AI Act obligations, so they can feed straight into your AI governance process.

What you get.

  • Reproduction steps with the exact requests and responses for each finding.
  • Severity based on demonstrated impact, not a signature match.
  • Remediation guidance your developers can act on.
  • An auditor-ready report you can share with customers and assessors.
