Prompt Injection & AI Threat Intelligence Database
PromptIntel is a free, continuously updated database of prompt injection attacks, jailbreaks, and LLM attack techniques, maintained by GuardionAI. Every threat is documented with its methodology, severity rating, framework mappings, and real prompt examples, so security teams can study — and test against — the techniques attackers actually use.
As of December 2, 2025, PromptIntel documents 89 AI security threats across 25 categories, with 29,334 recorded prompt injection and jailbreak examples.

How to Defend Against Prompt Injection
Cataloging attacks is only half the job. The techniques documented here are blocked at runtime by guardrails that classify prompts and responses inline, before they reach your model or agent. Guardion's prompt defense guard models score 0.95 F1 (0.92 recall, 0.98 precision) on published benchmarks, covering prompt injection, jailbreaks & adversarial attacks, bot abuse, spam.
See the full methodology and per-category results in the guard models benchmark documentation.

Frequently asked questions
What is prompt injection?
Prompt injection is an attack where adversarial text — typed by a user or hidden in content an AI system reads — overrides the model's instructions, causing it to leak data, bypass safety rules, or take unintended actions. PromptIntel documents 89 such techniques with real, categorized examples.
What is PromptIntel?
PromptIntel is Guardion's free, public threat-intelligence database for AI systems: 89 documented threats across 25 categories, covering prompt injection, jailbreaks, and LLM attack techniques — each with severity, methodology, and real prompt examples.
Where can I find prompt injection examples?
PromptIntel publishes 29,334 real prompt injection and jailbreak examples, free to browse at guardion.ai/promptintel. Each example is mapped to a technique, category, and severity level, so you can study or red-team against the attacks adversaries actually use.
How many prompt injection techniques exist?
As of December 2, 2025, PromptIntel catalogs 89 distinct LLM attack techniques across 25 categories. The largest categories right now are Encoding, Latentinjection, Web Injection, Leakreplay, Packagehallucination. The corpus grows continuously as new attack research is published.
How is this threat intelligence collected?
Threats are aggregated from public security research, red-team tooling, and attack patterns observed across guarded production traffic, then categorized by technique and severity. The catalog is updated continuously.
How do I defend against prompt injection attacks?
Runtime guardrails that classify prompts and responses inline block these techniques before they reach your model or agent. Guardion's prompt defense guard models score 0.95 F1 (0.92 recall, 0.98 precision) on published benchmarks across prompt injection, jailbreaks & adversarial attacks, bot abuse, spam.
