Skyblue Soft
Security tools for the AI era.
We make Sentinel, an AI security proxy that inspects LLM traffic in real time to catch prompt injection, PII leaks, poisoned RAG data, and agentic tool abuse before they reach production.
Skyblue Soft is built on three decades of network and systems security work, not a weekend hackathon. Our founder holds a PCNSA certification and is completing the OSCP, with years of production Unix/Linux infrastructure and enterprise network architecture experience.
01 — Product
Sentinel AI Firewall
Sentinel sits between your application and the LLM APIs it calls. It catches what generic API gateways miss: adversarial prompts, sensitive data leaving through model responses, and tool calls that shouldn't happen.

Built in the open
We open-source the tools we build to solve real problems. SlopScan detects hallucinated package names before they become a supply chain attack. It's free, it's on GitHub, and it's built into Sentinel.
