Jailbreak Detection Python Packages

little-canary

Detects prompt injection by its effect on a sacrificial canary model, not just pattern matching: untrusted input hits a powerless model first, a behavioral check reads the residue, and it returns block, flag, or pass before your primary model acts. Inbound preflight sensor, not a guarantee.

reasongate

Explainable security gate for LLM apps — blocks prompt injection with an auditable reason for every decision.

aicordon

Picket: a local signature detector for prompt injection, planted and typed - no model, no network, no dependencies

uptrain

UpTrain is an open-source unified platform to evaluate and improve Generative AI applications. We provide grades for 20+ preconfigured checks (covering language, code, embedding use-cases), perform root cause analysis on failure cases and give insights on how to resolve them.

shadowshield

Unified open-source security shield for agentic AI systems — defense-in-depth prompt-injection protection (canary tokens, agent-trace alignment audit, tool-call guarding, PII/secret scanning).

sovereign-shield

Deterministic AI defense framework: immutable input filtering, n-model cryptographic hash consensus, and self-learning adaptive rules. Zero dependencies. Hardware-sealed.

pyaigis

Get Claude Code and other AI agents approved for use at work — deterministic guardrails on every tool call, tamper-evident audit logs, and a generated IT-approval pack. Zero-dependency Python OSS.

aicordon-haystack

Picket: a local signature detector for prompt injection, planted and typed - no model, no network, no dependencies

aicordon-langchain

Picket: a local signature detector for prompt injection, planted and typed - no model, no network, no dependencies

injectionguard

Prompt injection detection for LLM applications and MCP servers. Detects jailbreaks, instruction override, encoded attacks. OWASP LLM #1 defense.

intentshield

Pre-execution intent verification for AI agents. Audits what your AI is about to do, not what it says. Zero dependencies, deterministic, hash-sealed.

zerolabz-sentinel

Sub-millisecond stateless AI guardrail reverse proxy and inference security middleware. Intercepts prompt injections, jailbreaks, and credential leaks in <0.4ms.

llm-injection-guard

Drop-in prompt injection defense for LLM apps and AI agents — detect, block, and audit injection attacks in real time

blackwall-llm-shield-python

Blackwall LLM Shield is an open-source AI security toolkit for JavaScript and Python that protects LLM apps from prompt injection, sensitive data leaks, unsafe tool calls, and hostile RAG content with prompt sanitization, PII masking, output inspection, policy enforcement, and audit trails.

llm-thorn
