Where are your photos and documents? With Nextcloud you pick a server of your choice, at home, in a data center or at a provider. And that is where your files will be. Nextcloud runs on that server, protecting your data and giving you access from your desktop or mobile devices. Through Nextcloud you also access, sync and share your existing data on that FTP drive at the office, a Dropbox or a NAS you have at home.
The easy web interface allows you to share files with other users on your server, to create and send password protected public links, to let others upload files to your cloud and to get notifications on your phone and desktop when a user on another cloud server shares files directly with you. And you can do all these things from the desktop or mobile clients, too.
We are deeply committed to protect the safety of the data of our customers and users. We are confident that Nextcloud offers the best security in the open source file sync and share industry, because:
we follow industry best practices around security (aligned to ISO27001)
we offer some of the highest open source security bug bounties
With Nextcloud, system administrators can control and direct the flow of data between users on or between servers. Rule based file tagging and responding to these tags as well as other triggers like physical location, user group, file properties and request type enables administrators to specifically deny access to, convert, delete or retain data following business or legal requirements. Nextcloud puts you in control of your data and keeps it safe.
Tracking changes to your files
The nextcloud Activity app shows file modifications, downloads of shares and changes to comments or tags, providing an overview in the browser, clients or via email notifications and an RSS feed.
Monitoring your Nextcloud server
The Monitoring app enables admins to monitor the health and performance of a Nextcloud system with a graphical UI and an API endpoint for monitoring apps.
Mobile and desktop clients
Nextcloud clients for Android, iOS and desktop systems allow you to sync and share files, in a fully secure way through an encrypted connection. The mobile clients feature automatic upload of pictures and videos you take and can synchronize select files and folders. The clients can handle multiple accounts, show all activity happening on your server and notify you of new events such as the availability of new shares.
External storage, secure encrypted
The external storage feature of Nextcloud gives you access to your data wherever it is. Nextcloud can access files stored with a wide variety of popular cloud service providers such as Amazon, Google and Dropbox, but you can also access them using standard protocols such as NFS, (S)FTP, WebDAV and more.
The Encryption App can encrypt data at rest for both local and remote storage, protecting data stored on networks outside of your infrastructure. Keys can be handled by an external key management server or stored locally, on the server. Nextcloud will keep your data where it is and retrieve it over a secure communication channel whenever you need to access it.
