## Choose when

### Choose ps-fuzz if…

- License: ps-fuzz is MIT, AI-Infra-Guard is Apache-2.0.
- Tags unique to ps-fuzz: ai-fuzzer, fuzzer, generative-ai, llm-fuzzer.
- Also covers Developer Tools.
- When you need to methodically test system prompts in generative AI applications for potential security flaws.

### Choose AI-Infra-Guard if…

- License: AI-Infra-Guard is Apache-2.0, ps-fuzz is MIT.
- Tags unique to AI-Infra-Guard: agent-security, ai-red-teaming, llm-evaluation, skills-security.
- Also covers LLM Frameworks.
- AI-Infra-Guard ships Docker support for self-hosted deployment.
- If you need advanced LLM jailbreak evaluation capabilities specific to the vulnerabilities identified by Tencent's research, consider using AI-Infra-Guard.

## When NOT to use ps-fuzz

- If your project does not involve generative AI applications or does not require prompt testing for security reasons.
- For tasks unrelated to the hardening and evaluation of system prompts, as ps-fuzz is specifically designed for this purpose.

## When NOT to use AI-Infra-Guard

- Avoid if you are looking exclusively for a tool that focuses solely on the runtime behavior of LLMs without broader infrastructural scanning capabilities.
- Not recommended when your primary focus is on network-level security rather than comprehensive AI infrastructure security assessments and evaluations.
