Rampart

Rampart is a distributed network defense platform that unifies firewall management across Linux systems and multiple cloud providers through a single YAML policy interface. It combines traditional packet filtering with an autonomous threat detection system that analyzes traffic patterns in real-time to identify and block attacks automatically across clusters.

Designed for infrastructure teams and security engineers, Rampart abstracts the complexity of managing eBPF, nftables, and cloud security groups. Key capabilities include Layer-7deep packet inspection for DNS and HTTP, multi-cloud orchestration for AWS/GCP/Azure, Raft-based distributed consensus with mTLS, and built-in observability via Prometheus and audit logging. The maker indicates it was built with Claude Code and Gemini CLI.
