UMAI Core CE – An eBPF semantic firewall for AI protocols
UMAI Core is an open-source kernel semantic firewall designed for the AI ecosystem. It operates within the Linux kernel using eBPF to validate and enforce AI application protocols at high speeds. The firewall inspects incoming packets and can drop unauthorized requests before they consume system resources.
- ▪UMAI Core runs directly inside the Linux kernel space using eBPF and XDP.
- ▪It evaluates AI application protocols at raw line speed, dropping malicious requests instantly.
- ▪The firewall features deep-packet parsing engines optimized for various AI protocols.

Opening excerpt (first ~120 words) tap to expand
UMAI Core (Community Edition) The Open-Source Kernel Semantic Firewall (KSF) for the AI Ecosystem UMAI Core is not a traditional firewall. It is a lightweight, open-source network validation and enforcement agent that runs directly inside the Linux kernel space using eBPF (Extended Berkeley Packet Filter) and XDP (eXpress Data Path). By hooking straight into the earliest possible stage of the network driver's packet entry gate, UMAI Core evaluates and enforces AI application protocols at raw line speed. It inspects conversational structures, tools, and machine identities the exact microsecond they arrive, dropping unauthorized or malicious requests before the main operating system spends memory or CPU cycles processing the packet.
