Versions:
Zenarmor 2.1.1 is a hardware-agnostic network security platform that installs natively on Windows, Linux, FreeBSD, and cloud hypervisors, enabling organizations to deploy enterprise-grade perimeter protection wherever data paths exist without locking into proprietary appliances. The software performs real-time deep packet inspection, application-aware filtering, intrusion detection and prevention, TLS fingerprinting, and encrypted traffic analysis at wire speed, giving administrators unified visibility into east-west and north-south traffic across branch offices, remote workers, container hosts, and multi-cloud tenants. Typical deployments see Zenarmor inserted as a transparent bridge on a laptop for personal defense, spun up as a virtual machine in an on-premise ESXi cluster to protect internal VLANs, or launched as a container instance inside Kubernetes to enforce micro-segmentation between pods, all managed from a single web console that exports policies to every endpoint. Because the engine stores rules and logs locally, users retain full custody of sensitive metadata, satisfying compliance mandates that prohibit third-party cloud analytics. Four major versions have been released since the project’s inception, each expanding protocol support, performance optimizations, and REST API hooks for SOAR integration. The current 2.1.1 branch adds WireGuard VPN filtering, a rewritten IPS signature loader, and ARM64 acceleration for Raspberry Pi gateways. Zenarmor is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation of multiple applications.
