Two Worlds of
Defense
We are not a content moderation layer. We are an immune system for the autonomous age.
Citadel OSS
The Immune System
The bedrock of secure AI. Powered by open-source BERT for semantic analysis, layered with heuristics and high-performance Go-native embeddings. Blazing fast, secure, and fully customizable.
No Performance Tax
Don't double your latency with guardrail chains. Citadel runs locally in milliseconds, invisible to the user.
Best-in-Class Defense
Multi-layer protection: Behavioral Heuristics + Specialized Neural Networks + Semantic Analysis.
100% Open Source
Apache 2.0. Audit the code. Run it air-gapped. Zero data exfiltration risk.
Mighty Multimodal
The Agentic Gateway
The world's first security layer for the multimodal era. We catch attacks that don't rely on text.
Prompt Injection Accuracy
Latency
Expertise
Visual Steganography Detection
Catch "invisible" attacks—white-on-white text, low-opacity instructions that Vision LLMs miss.
Deep Binary Analysis
Recursive scanning of PDFs, archives, and embedded streams. Detect payloads hidden in document metadata.
