TESTIMONIALS
Sereno IT worked closely with Statons to transform their IT operations into a modern, efficient, and scalable setup. The first step was addressing their outdated on-premises server, which was replaced with a secure, cloud-based storage solution using Microsoft SharePoint. This migration not only improved accessibility for staff working across six offices without the need for unreliable VPNs. This also eliminated the need for an expensive backup system, and allowed for a downgrade on firewalls, saving Statons approximately £40,000 over three years.

Your files are securely stored on Microsoft’s hosted servers, which ensures reliable access, backups, and compliance.
Originally, Office 365 was a subscription-based service that comprised Microsoft Office apps (Word, Excel, Outlook, etc.) and cloud services like OneDrive and Exchange. In 2020, most Office 365 plans were rebranded under the Microsoft 365 name. Microsoft 365 includes everything Office 365 has, plus advanced security features, device management, and collaboration tools.
