Altaro

What Altaro does

Altaro is a Raleigh-headquartered software vendor that builds backup and recovery solutions targeting small and mid-market IT environments, specifically Hyper-V and VMware virtual machines, Windows Server, and Microsoft 365 data (mail, files, collaboration content). The core product line consists of VM Backup for virtualized infrastructure and 365 Total Backup for Microsoft 365, with an adjacent 365 Total Protection module bundling advanced threat protection, compliance features, and security awareness for Microsoft 365 tenants. All products are delivered as subscription-licensed software, priced per VM or per user, and supported by a centralized management/control plane inherited from the Hornetsecurity portfolio post-acquisition.

The company operates a strictly channel-first go-to-market: it does not run direct enterprise sales, instead selling exclusively through resellers, managed service providers (MSPs), and IT consultants via two parallel programs — a dedicated Altaro Partner Program for backup-only sellers and the broader Hornetsecurity Partner Program for partners wanting to bundle email security, backup, compliance, and awareness solutions. Partner self-service runs through a dedicated Altaro Partner Portal alongside Hornetsecurity's unified Control Panel, and pricing is not publicly disclosed (a price-calculator and "Buy Now" flow route buyers to Hornetsecurity's checkout).

Altaro was founded in 2009 and is now a brand and product line inside Hornetsecurity GmbH, a German-headquartered strategic operating company that delivers "AI-powered, cloud-based security, compliance, backup, and security awareness" services. Under Hornetsecurity, Altaro continues to be sold and supported through Hornetsecurity's platforms and partner network, and commercial operations (pricing, checkout, program signup) have been consolidated onto Hornetsecurity infrastructure. Simon Attard is identified as co-founder and Chief Product Officer.
