OWASP LLM Top 10 Assessment
🔒 In your browserSelf-assess your LLM app against the OWASP LLM Top 10 — get a risk score and mitigations.
How it works
Answer a few questions about your LLM app or agent. You'll get a risk profile mapped to the OWASP Top 10 for LLM Applications (2025), prioritized by exposure, with concrete mitigations for each gap. Nothing is uploaded — it's computed in your browser.
Crafted input overrides instructions or smuggles commands via retrieved content.
The model leaks secrets, PII, or proprietary data in its output.
Compromised models, datasets, plugins, or MCP servers introduce risk.
Tampered training/fine-tuning/RAG data biases or backdoors the model.
Model output is trusted downstream (SQL, shell, HTML, tool args) without validation.
The agent has more tools, permissions, or autonomy than the task needs.
Secrets or security-critical logic live in the system prompt and can be extracted.
RAG vector stores leak data across tenants or are poisoned via embeddings.
Confident but wrong output (hallucination) is relied upon in decisions.
No limits on tokens/tool calls/cost enable denial-of-wallet and DoS.
This maps to the public OWASP Top 10 for LLM Applications and is a self-assessment starting point — not a certification or a substitute for a professional security review.
About the OWASP LLM Top 10 Assessment
The OWASP Top 10 for LLM Applications is the industry-standard list of the biggest security risks in AI apps and agents — prompt injection, sensitive-information disclosure, excessive agency, and more. This free self-assessment asks a few plain questions about your app and turns them into a risk profile: which OWASP LLM risks you're exposed to, a readiness score, and specific mitigations for each gap.
It runs entirely in your browser — nothing about your system is uploaded.
How to use it
- Answer yes / no / unsure to the questions under each of the ten risks.
- Watch the readiness score and per-risk status (Exposed / Partial / OK) update live.
- Read the mitigations shown for each exposed risk, and copy the full report.

Frequently asked questions
What is the OWASP Top 10 for LLM Applications?
It's a community-driven list, published by the OWASP GenAI Security Project, of the ten most critical security risks specific to applications built on large language models.
Is this a certification?
No. It's a self-assessment to help you find gaps and prioritise fixes — not a formal audit or certification, and not a substitute for a professional security review.
How is the readiness score calculated?
Each risk is scored by how many of its questions you answered in the risky direction (with 'unsure' counted as half). The score is the inverse of your average exposure across the risks you answered.
What do I do with an 'Exposed' risk?
Each exposed or partial risk lists concrete mitigations. Several link to ToolsHub tools — the MCP Security Scanner, Prompt Secret Redactor, Prompt Injection Checker and the Red-Team Prompt Generator.
Is anything uploaded?
No. Your answers and the report never leave your browser.
