Analyst Report
Cohesity named a Leader again!
We were recognized as a Leader in the 2025 Gartner® Magic Quadrant™ for Backup and Data Protection Platforms for the 6th time.
Testimonials
The main reason we chose the Cohesity hosted service was so we wouldn’t have to bring everything back on-prem for M365 restores. With BaaS, we can keep everything in the cloud so we aren’t using excessive bandwidth to pull that data down every day. Although cost savings were not the main driver in our decision to go with Cohesity for M365, it will be less expensive to keep our data in the cloud rather than buying more on-prem hardware in the future.”

We do everything we can to prevent cyberattacks, but having the ability to restore clean M365 data from Cohesity’s immutable backup copies means we have a solid fallback."

Cohesity plays especially well with Exchange. After switching to Cohesity we were able to reclaim six Exchange servers previously reserved for snapshots for an immediate return on investment."

Cohesity gave us the ability to start leveraging our OneDrive, SharePoint, and Team sites more without worrying about excessive cost overruns.”

After the ransomware attack we restored all 2.5 TB of M365 data—protected by Cohesity DataProtect on Azure—in 12 hours. “We paid no ransom.”

We use Microsoft 365 with its built-in retention policies, but that isn’t robust backup.We count on Cohesity for robust, reliable backup of our Exchange Online user mailboxes onsite as an additional fail safe so if something happens—like ransomware—we have a way to quickly recover mailboxes, files, and sites. The added benefit is we can perform searches within a user’s mailbox and do recoveries directly from Cohesity. We expect to use Cohesity soon to also backup our SharePoint Online and Microsoft Teams environments. With corporate data shared across these collaboration platforms, it becomes increasingly critical to be able to retain and restore from our backups."

Cohesity helped us eliminate our existing storage filer and it does everything we need it to do for backups—all for 30–40% less than other data management solutions. It’s fun to work with a company actively delivering capabilities fast, like backup for Microsoft 365, that provide real value to customers at no additional cost.”
