🛡️ Cortiqa Guard-A40M: Universal AI Security Firewall
Cortiqa Guard-A40M is an ultra-fast (~2ms) dedicated 40.5M parameter AI Firewall engineered by Cortiqa to inspect, classify, and block adversarial attacks before they reach production LLMs (OpenAI, Gemini, Claude, LLaMA, Ollama, vLLM).
Built with a Hybrid Defense Architecture:
- Neural Transformer Core (40.5M GQA Transformer): Intercepts semantic attacks (Jailbreaks, Prompt Injections, Toxic Abuse, Malicious payloads) with 83%+ confidence in ~2ms.
- Deterministic Pattern Engine: Intercepts strict financial leaks (Visa, Mastercard, Amex, Discover, European IBAN, Indian Aadhaar & UPI) in under 0.5ms.
