Why IT teams choose Virto

Built to pass your security review, not work around it

Your content stays in your tenant

Virto apps process your content without storing it: it stays in your Microsoft 365 tenant or on your own SharePoint servers. The one exception is Virto Shared Calendar, which keeps shared calendars on VirtoSoftware's Azure.

Need more? Virto Calendar App and Virto Alerts & Reminder App can also run entirely inside your own Azure tenant.

Works with the calendars and lists you have

No migration and no second system to keep in sync. Virto apps read what your teams already keep in Microsoft 365, and Virto Calendar App adds Google and any iCal feed.

  • Outlook
  • Exchange
  • SharePoint
  • Teams
  • Planner
  • Lists

FAQ

Before you ask

Something else? sales@virtosoftware.com

Is there a free trial?

Yes. Virto Calendar App, the Kanban, alerts and forms apps and the on-premises web parts come with a 30-day free trial. Virto Shared Calendar has a free plan instead (up to 15 calendar entries per user), and Virto Charts & Data Visualization App, Virto Time Blocker App and Virto Slideshow App are free.

Microsoft 365 or on-premises — which apps do I need?

If your SharePoint runs in Microsoft 365, choose the Microsoft 365 or Teams apps: they install from Microsoft Marketplace. If you run SharePoint Server in your own data center, choose the SharePoint On-Premises web parts. They are separate products with separate licences.

Where is my data stored?

Your content stays in your Microsoft 365 tenant or on your own SharePoint servers; Virto apps process it without storing it. The one exception is Virto Shared Calendar, which stores shared calendars on VirtoSoftware's Azure. Details are in the Trust & Security Center.

Do on-premises licences expire?

No. An on-premises licence is perpetual. Renewing maintenance brings updates and support; letting it lapse never stops the product from running. Maintenance for a single web part renews at 50% of its list price; a Productivity Kit renews at the full kit price.

Do you offer discounts for nonprofits and education?

Yes — 15% for nonprofit and educational organizations. Write to sales@virtosoftware.com before you buy.

Is VirtoSoftware the same company as Virto Commerce?

No. VirtoSoftware (VirtoSoftware UAB) is an independent vendor of Microsoft 365 and SharePoint apps, a separate company from Virto Commerce, the B2B e-commerce platform.
