Best for one global file system across offices for enterprises

CTERA replaces separate NAS devices with one global file system over cloud or on-premises object storage, reached through Edge Filers and apps. No price is published, each site needs virtualisation capacity, and some protection tools are Windows and macOS only.

Who CTERA is for

  • Fits if you run offices that need to share one set of files
  • Works for enterprises that want a private or CTERA-hosted deployment

Who CTERA is not for

  • Not for you if you are a small team, as it is sold to enterprises
  • Skip it if you want a price or a trial
  • Watch out: each site needs its own virtualisation capacity for the Edge Filer
  • Watch out: Drive Connect and Drive Protect list Windows and macOS only

Keep CTERA, or make your own?

Keep it

To replace CTERA you would be making files kept in step across devices without losing one. That is not a weekend's work, with an AI app builder or without one.

That makes this kind of software worth paying for, not this one in particular: 79 of the 91 other file storage and sync services grade higher.

What you could not

  • Files kept in step across devices without losing one.
  • Storing and serving files for other people.
  • A file manager working directly on your disk.
  • Apps for macOS, Windows, iOS and Android that stay in step with each other.
  • End-to-end encryption done properly.
  • AI features, unless you pay a model provider for each request yourself.

What this rests on. CTERA’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.

What is CTERA?

CTERA sells the CTERA Intelligent Data Platform, a software-defined global file system that replaces separate NAS devices with one namespace over cloud or on-premises object storage. Offices reach files through virtual Edge Filers, and users through web, desktop and mobile apps. It is sold to enterprises, with no published prices.

Worth knowing

  • No prices are published; the site offers demos and sales contact only.
  • Deployment is either a private subscription or a CTERA-hosted model, so hosting responsibility depends on which is chosen.
  • Edge Filers are virtual appliances, so each site needs its own virtualization capacity.
  • Drive Connect and Drive Protect are listed for Windows and macOS only.

Key features

Global file system
Cloud and on-premises storage silos are presented as one logical namespace, managed from a web-based multi-tenant portal.
Edge Filers
Virtual appliances at remote sites provide caching and NFS and SMB gateways, in sizes the site says range from a few users to thousands.
CTERA Drive apps
Drive Share syncs and shares files on Windows, macOS, iOS and Android; Drive Connect mounts the file system on Windows and macOS; Drive Protect backs up desktops and laptops.
Encryption and key control
The vendor says data is protected with AES-256 end-to-end encryption and that customers keep control of their keys.
Ransomware and archiving tools
Ransom Protect and immutable snapshots handle attacks, and an AI-assisted archiving service helps decide what to move to cheaper storage.
