LLM Security & Prompt Injection Audit

Red-Team Your LLMs to Prevent Data Leaks, System Hijacking & Jailbreaks

LLM applications introduce entirely new attack surfaces, such as direct prompt injection, indirect prompt injection via untrusted user documents, and model data exfiltration, that traditional firewalls cannot block. Quantum Bases performs specialized LLM Risk Auditing and adversarial red-teaming. Our security team simulates real-world attacker techniques to bypass system prompt instructions, trick AI agents into executing unauthorized tools, and extract sensitive system data. We then harden your system prompts, implement input sanitization middleware, and deploy output guardrails.

Key Operational Challenges

What We Solve in LLM Security & Prompt Injection Audit

Challenge #1

Attackers using clever prompt tricks to force the LLM to reveal proprietary system instructions.

Production Solution

System prompt hardening and pre-inference prompt sanitization filters.

Challenge #2

Indirect prompt injection where malicious text inside PDFs or web pages hijacks AI agent tools.

Production Solution

Document parsing sanitization and secondary tool call verification guardrails.

Challenge #3

Model outputting sensitive user data or toxic content during multi-turn chats.

Production Solution

Real-time output guardrail integration (NeMo Guardrails / Llama Guard).

Frequently Asked Questions

Expert Guidance on LLM Security & Prompt Injection Audit

What is indirect prompt injection?

Indirect prompt injection occurs when an attacker hides malicious instructions inside a PDF or web page that the AI agent later parses, tricking the agent into executing bad commands.

How do guardrails protect LLM applications?

Guardrails act as a real-time firewall, checking user prompts before they reach the model and verifying model answers before sending them to the user.
