Simplify your data center
Proxmox delivers secure, flexible, and reliable open-source enterprise solutions for organizations that want to modernize virtualization, backup, and infrastructure management without unnecessary complexity or budget pressure.
From day-to-day operations to multi-site scale, Proxmox helps teams simplify the data center with practical, production-ready platforms.
Proxmox Virtual Environment
Proxmox Virtual Environment (Proxmox VE) is a complete, open-source server management platform for enterprise virtualization. It combines KVM (full VM virtualization) and Linux Containers (LXC) on a single platform, and adds software-defined storage and networking plus high-availability clustering through an integrated web interface.
What it enables
- Run VMs + containers side by side: Use KVM for Windows and Linux VMs and LXC for lightweight, isolated Linux workloads giving maximum flexibility in production.
- Centralized management (GUI + CLI + API): Manage nodes, clusters, VMs, containers, tasks, and logs from one web UI; automation is supported via CLI and REST API.
- High availability & operational resilience: Built-in tools for HA clustering and integrated disaster recovery workflows simplify continuity planning.
- Scale-out clustering: Start with a single node and grow into a cluster without redesigning your architecture.
Where Proxmox VE fits best
Proxmox VE is ideal for partners delivering virtualization refresh projects, consolidations, private cloud foundations, and modern hybrid environments especially where customers want strong capability, clarity in operations, and an open ecosystem.
Proxmox VE – Comparison snapshot
Proxmox Virtual Environment (VE) is a modern, open-source virtualization platform built to simplify infrastructure consolidation while keeping operations efficient and predictable. It delivers zero license cost with full functionality, helping reduce operating expenses and admin overhead while improving infrastructure flexibility, security, and reliability.
Key differentiators at a glance:
Two virtualization approaches in one platform: full virtualization with KVM/QEMU plus Linux containers (LXC).
True cluster-first design: built-in clustering where any node can manage the cluster (no fixed master), plus High Availability.
Broad storage and networking options: support for common and advanced storage backends (including distributed and filesystem options) and virtual networking (bridging and Open vSwitch).
Enterprise-grade management stack: full web GUI, CLI, and REST API, plus monitoring integrations and granular permissions.
Complete VM lifecycle tooling: integrated backup/restore, live migration (including storage live migration), snapshots, replication, templates/clones, and import/export support.
Support your way: free community resources plus subscription-based enterprise support, training, and public documentation.
Proxmox Backup Server
Proxmox Backup Server (PBS) is an enterprise backup solution for VMs, containers, and physical hosts, designed to reduce storage and network load through incremental, fully deduplicated backups. It also includes strong encryption and integrity mechanisms helpful even when backing up to targets that are not fully trusted.
Key capabilities partners care about
- Incremental + dedup by design: Only changes are sent; backups are deduplicated server-side to save storage and reduce network impact.
- Fast compression for large environments: Uses Zstandard (ZSTD) for high-speed compression with strong ratios.
- Security-first backup architecture: Supports encrypted client-to-server traffic; authenticated encryption is performed client-side (AES-256-GCM) so data is protected before it reaches the server.
- Integrity verification: Uses checksumming (SHA-256) and supports scheduled verification to detect corruption/bit rot and confirm backup consistency.
- Remote sync for offsite resilience: Synchronize datastores to other locations efficiently by transferring only changes since the last sync.
- Tape backup option: Built-in tape workflows support LTO (including retention policies and library support), useful for long-term archival strategies.
Tight integration with Proxmox VE
PBS is designed to work seamlessly with Proxmox VE, enabling straightforward backups for VMs and containers and supporting advanced restore workflows (including “live-restore” behavior noted in PBS integration details).
Proxmox Mail Gateway
Proxmox Mail Gateway (PMG) is an open-source email security solution designed to protect mail servers from modern email threats, covering spam, viruses, phishing, and trojans, while giving administrators strong visibility and control over inbound and outbound mail flows through a web-based interface.
What it’s used for
- Mail proxy security layer: Deployed between firewall and mail server to analyze and filter email traffic before it reaches internal systems (“before-queue filtering” approach is part of the described deployment flow).
- Threat detection stack: Integrates ClamAV and SpamAssassin among the referenced filtering methods for anti-virus and anti-spam processing.
- Operational visibility: The Proxmox Message Tracking Center tracks and summarizes logs and helps admins quickly investigate message flow and filtering outcomes.
- High availability: Includes a Proxmox HA clustering approach for resilient mail security deployments.
Proxmox Datacenter Manager
Proxmox Datacenter Manager (PDM) is a centralized management solution built to oversee multiple nodes and clusters of Proxmox-based virtual environments. It provides an overall view of distributed infrastructures and helps teams run operations across clusters and data centers through a unified interface.
Highlights for larger / multi-site environments
- Central cockpit: Unified overview of clusters, nodes, guests, and datastores across locations with powerful search for large environments.
- Multi-cluster operations + live migration: Manage actions at scale (start/stop/reboot/migrate many guests) and support live migrations between independent clusters.
- Identity & governance: Supports centralized identity integration (LDAP, Active Directory, OpenID Connect) and role-based access control concepts to support least privilege and audits.
- Operational efficiency: Includes update management visibility across Proxmox VE and PBS infrastructure from one panel.
- Ecosystem alignment: Native compatibility with Proxmox VE and Proxmox Backup Server to create a cohesive management layer.
