What is Superagent?
Superagent is an open-source AI firewall engineered to provide reasoning-driven runtime protection for your Large Language Models. It directly addresses the critical security vulnerabilities inherent in LLM operations, safeguarding your applications from prompt injections, sensitive data leaks, and malicious backdoors. Designed for developers and enterprises leveraging AI, Superagent ensures your AI interactions remain secure, compliant, and performant.
Key Features
🛡️ Comprehensive Runtime Threat Defense: Superagent actively monitors and blocks three primary LLM attack vectors in real-time. It prevents prompt injections that manipulate AI behavior, stops data leaks by preventing exposure of sensitive information (like API keys or PII) in responses, and detects backdoors by identifying and neutralizing malicious code generation patterns.
⚡ Sub-50ms Detection with NinjaLM: At its core, Superagent leverages NinjaLM, a fine-tuned small language model, to analyze every prompt and response. This allows for reasoning-driven threat detection within sub-50 milliseconds, ensuring rapid protection without compromising the speed or responsiveness of your AI applications.
🚦 Intelligent Model Routing: Gain control over your LLM traffic with Superagent's flexible model router. It directs requests based on your defined policies, cost considerations, and latency requirements, enabling you to seamlessly manage and secure interactions across various AI providers like OpenAI, Anthropic, and Gemini.
📊 Full Observability for Compliance: Superagent provides always-on logs and traces for every request, complete with detailed decision reasoning. This comprehensive observability is crucial for debugging, ensuring compliance with standards like SOC2, GDPR, and OWASP, and maintaining a robust audit trail of all AI interactions.
Use Cases
Securing AI Agents: Protect your autonomous and coding agents (like those powered by Cursor or custom builds) from malicious prompts, ensuring they execute tasks safely without data exposure or code-level backdoors.
Safeguarding Internal AI Applications: Deploy Superagent as a critical security layer for custom APIs, microservices, and internal tools that integrate LLMs, preventing sensitive corporate data from being compromised.
Enhancing Third-Party AI Tool Use: Extend robust security to your interactions with external LLM platforms such as Claude Code and ChatGPT, ensuring that prompts and responses are free from threats before they reach your users or systems.
Why Choose Superagent?
Superagent stands apart by offering a unique blend of advanced security and operational flexibility for your AI stack:
Reasoning-Driven, Not Just Static Filters: Unlike traditional security measures that rely on static rules, Superagent's NinjaLM uses contextual reasoning to detect novel and sophisticated attacks that static filters often miss, providing a deeper layer of protection.
Seamless, Drop-in Integration: Implement enterprise-grade AI security with minimal effort. Superagent acts as a transparent proxy; simply swap your existing API URL to route through the firewall – no extensive code refactoring is required.
Open-Source Transparency & Trust: As an MIT-licensed open-source solution, Superagent offers complete transparency and allows for community contributions, fostering trust and enabling full control over your security infrastructure.
Flexible Deployment Options: Whether you require a fully managed, hosted solution for rapid deployment and automatic scaling, or prefer complete data ownership and control with an on-premise, self-hosted deployment, Superagent adapts to your operational needs.
Conclusion
Superagent provides the essential, reasoning-driven security layer modern AI applications demand. By offering real-time protection against critical LLM threats, it empowers developers and organizations to build, deploy, and utilize AI with confidence.
