Overview
VM Backup, previously marketed under the Altaro name, is a virtual machine backup product from Hornetsecurity, which Proofpoint acquired on 8 December 2025 for total consideration of US$1.8 billion[20]. At the time Hornetsecurity reported annual recurring revenue of nearly US$200 million, more than 12,000 channel partners and MSPs, and more than 125,000 customers[20]. The site now uses “Hornetsecurity by Proofpoint” branding[19].
VM Backup protects Microsoft Hyper-V, VMware and Proxmox from a single console[19]. Its licensing is unusual for its flexibility: perpetual licences are sold per host with unlimited sockets and VMs in Standard, Unlimited and Unlimited Plus editions, while a monthly subscription for the Unlimited Plus edition is charged per backed-up VM with no upfront cost[19]. Perpetual customers need a Service Maintenance Agreement for support and upgrades. A free edition covers 2 VMs per host with no time limit, and a 30-day trial of the full product is available[19]. Prices were not listed on the page consulted. The product is focused on virtual machines and does not cover the range of physical, SaaS and database sources found in broader suites.
