Ethicore Engine™ - Guardian SDK is the first pip-installable AI threat protection layer for Python. Drop it in front of any LLM; OpenAI, Anthropic, Ollama, etc, to block prompt injection, jailbreaks & role hijacking before they reach the model. Three defense layers: pattern matching, offline ONNX semantic embeddings, and ML behavioral inference. No cloud dependency, no latency overhead. Open-core: free community edition on PyPI. Licensed tier adds 30-category threat library + production models.see more

About
In today's rapidly evolving digital landscape, integrating powerful Large Language Models (LLMs) into your applications brings incredible potential, but it also introduces significant, often unseen, security vulnerabilities. That is where the Ethicore Engine Guardian SDK steps in, offering you a robust, first-of-its-kind defense layer designed specifically for Python environments. Imagine deploying cutting-edge AI capabilities with the confidence that malicious inputs are being stopped dead in their tracks, long before they can compromise your system or data. This SDK is not just another security tool; it is an essential, pip-installable shield that sits directly in front of any LLM you are using—whether you are leveraging OpenAI, Anthropic, local Ollama instances, or others. It fundamentally changes the risk profile of your AI integrations by proactively neutralizing threats like prompt injection, sophisticated jailbreaks, and attempts at role hijacking, ensuring your application behaves exactly as intended, every single time.
What truly sets the Guardian SDK apart is its multi-layered, defense-in-depth architecture, engineered for maximum effectiveness without sacrificing performance. We understand that security measures cannot slow down innovation, which is why this solution operates entirely without cloud dependency, meaning you experience zero added latency overhead. The protection works across three distinct levels: a foundational layer of advanced pattern matching to catch known attack signatures, a sophisticated offline ONNX semantic embedding layer that understands the meaning and intent behind text, and finally, a powerful ML behavioral inference layer that detects anomalies in real time. This comprehensive approach means that even novel or zero-day attacks have a significantly reduced chance of success. The community edition, available freely on PyPI, provides immediate access to this core protection framework, allowing developers to start securing their projects right away.
For organizations operating at scale or handling sensitive data, the licensed tier elevates your security posture even further. This premium offering unlocks an extensive, continuously updated threat library spanning over 30 distinct categories of known AI exploits, coupled with highly optimized production-grade models. By integrating the Ethicore Guardian SDK, you are not just adding a firewall; you are embedding proactive intelligence into your application's core logic. This allows your team to focus on building groundbreaking features, secure in the knowledge that the integrity and safety of your AI interactions are being managed by a dedicated, high-performance security engine built by experts in the field. It is the simplest, fastest way to move from deploying an experimental AI feature to launching a resilient, production-ready system.
