AI Red Teaming ServiceFor AI services you can trust,
AI security validation from an attacker's perspective
Across AI services—generative AI, RAG, AI agents, and more— we identify security, safety, and policy-compliance risks ahead of time through adversarial inputs and real attack scenarios
AI answers as if everything's normal,
but information can leak and systems can be attacked
AI services can expose information and malfunction depending on the input and context. Attackers use Prompt Injection and Jailbreak to manipulate responses and behavior and bypass policies, and the result—leaks of sensitive information and system misuse—erodes both trust in the service and your control over it.
Before launching an AI service, advance validation of its trustworthiness and operational control is essential.
We perform tailored security validation across diverse forms of AI services.
Prompt Attack
Rise of AI-Specific Attacks
Attack techniques unique to AI services—Prompt Injection, Jailbreak, Indirect Prompt Injection, and more—are surging.
Data Leakage
Risk of Sensitive Data Exposure
The risk of exposing sensitive information and internal knowledge or leaking the system prompt is ever-present, and hallucination introduces brand-trust risk.
Agent Risk
Potential Tool / API Misbehavior
Tool and API integrations carry the risk of excessive privilege use and misbehavior, and new security threats are emerging in AI agent environments.
Compliance
Regulatory Compliance Required
Compliance with AI security regulations such as OWASP Top 10 for LLM and the EU AI Act is becoming mandatory, and trustworthiness validation is required before launch.
How It Differs from Existing Services
See at a glance how AI Red Teaming differs from penetration testing and red teaming.
| Item | Penetration Testing (PT) | Red Team (RT) | AI Red Teaming |
|---|---|---|---|
| Assessment Target | Technical vulnerabilities in web, app, and infrastructure | Organizational detection and response framework | AI service malfunction, misuse, information exposure, policy bypass |
| Perspective | Discovering system-level vulnerabilities | Comprehensive validation based on real attack scenarios | Domain dedicated to AI-specific risk |
| Key Techniques | Based on OWASP Top 10 and CVEs | APT Simulation, MITRE ATT&CK | Prompt Injection, Jailbreak, RAG Manipulation |
| Deliverables | Vulnerability report, remediation guide | Attack timeline, detection-status analysis | Risk matrix, AI-specific remediation guide |

Delivery Process — A Systematic 5 Stages
We comprehensively validate the security risks of your AI service through a systematic five-stage process.
Scoping & Threat Modeling
Scoping and Threat Modeling
We identify the service architecture, privileges, data flows, and attack surface, and build a threat model.
Scenario Design
Attack Scenario Design
We design attack scenarios suited to your industry and business context, and build out the test cases.
Execution
Attack Execution
We carry out multi-angle attacks combining automated and manual techniques to surface real vulnerabilities.
Analysis
Vulnerability Analysis and Assessment
We set priorities through vulnerability reproduction, risk assessment, and business-impact analysis.
Remediation & Re-Test
Remediation and Re-Validation
After improving prompts, guardrails, privileges, and operational controls, we re-validate to confirm the security level.
Deliverables & Value Proposition
We provide the validation results in a form that both executives and practitioners can put to use.
- Executive Summary Report
- A summary of key risks, business impact, and decision points
- Remediation Guide
- Concrete remediation recommendations for prompts, guardrails, privileges, and operational controls
- Re-Assessment Report
- Re-validation results after applying remediations, plus residual risk and follow-up recommendations
- Risk Matrix
- A quantitative assessment of each vulnerability's risk level, priority, and scope of impact
- Attack Scenarios & Evidence
