LLM Security Testing for Modern AI

Ship LLM features with confidence through adversarial security testing built for the risks traditional pentests overlook. Vynox Security probes prompt injection, jailbreaks, sensitive-data exposure, RAG retrieval paths, and agent tool use with human-led validation. Receive clear evidence, reproducible findings, and stack-specific remediation guidance that helps engineering teams strengthen AI applications before release, customer reviews, or compliance milestones.

Our LLM Security Testing Services

Targeted adversarial assessments for LLM applications, RAG systems, agents, models, and AI deployment risks.

LLM Penetration Testing

Manually test LLM applications against 40+ prompt injection and jailbreak techniques, with OWASP LLM Top 10 coverage, evidence, and developer-ready remediation steps.

Prompt Injection Testing

Determine whether attackers can override instructions, extract system prompts, bypass guardrails, disclose sensitive information, or trigger unintended model behavior through focused testing.

RAG Pipeline Security

Test retrieval workflows for cross-tenant document exposure, access-control bypass, vector database poisoning, query manipulation, and embedding inversion risks.

AI Agent Security

Assess autonomous agents and tool integrations for tool-call injection, goal hijacking, privilege escalation, unsafe delegation, and data exfiltration through legitimate channels.

Model Extraction Testing

Evaluate whether targeted queries can reveal proprietary training data, fine-tuning signatures, model behavior, or intellectual property that competitors could use to clone systems.

AI Red Teaming

Simulate determined adversaries across LLMs, agents, and pipelines, chaining vulnerabilities into realistic scenarios that demonstrate business impact and control gaps.

Human-Led AI Assurance

Find AI Risks Before Attackers Do

Vynox Security tests the behaviors, integrations, and data flows that make LLM products valuable—and potentially vulnerable. Rather than relying on scanner output, specialists validate exploitable paths across prompts, retrieved documents, model responses, and connected tools. Each engagement delivers technical proof, OWASP LLM Top 10 mapping, CVSS-scored findings, and practical remediation guidance so engineering leaders can prioritize fixes, satisfy security reviews, and release AI capabilities with stronger assurance.

Frequently Asked Questions

What is LLM security testing?

LLM security testing is an adversarial assessment of an AI application’s model behavior, prompts, data access, integrations, and guardrails. It looks for risks such as prompt injection, jailbreaks, system-prompt leakage, sensitive-data disclosure, unsafe output handling, and unintended tool actions. Vynox Security uses manual, human-led validation and maps AI findings to the OWASP LLM Top 10.

How is LLM security testing different from a traditional penetration test?

What does an LLM penetration test include?

Can you test RAG applications for data leakage?
