Proxmox Virtual Environment (Proxmox VE) is an open‑source virtualization platform built on Debian Linux that integrates KVM for full virtualization and LXC for lightweight container workloads. Proxmox VE allows virtual appliances, such as right‑sized single‑core firewalls, to operate efficiently in decentralized infrastructures. When deployed in branch offices, edge computing sites, and SMB environments, Proxmox VE enables secure network segmentation and full Layer 7 security functionality while maintaining near‑native performance with minimal compute overhead.
