“SpiderOak nails its colors very clearly to the mast with its focus on security and privacy. If these are the most important elements you require then it is clearly the best choice”
PC Advisor
“Dropbox is hostile to privacy, unlike 'zero knowledge' SpiderOak.”
Edward Snowden to The Guardian
“Go end-to-end encrypted on email and cloud storage too...SpiderOak ONE is like a super-private Dropbox.”
“Cloud storage services such as SpiderOak have architected its service so that the decryption key is accessible only to the account owners.”

More than Just Backup.

You know the best time to backup your photos, files, or work? Before you need to! We hear from thousands of our users every year who had disaster strike - a house fire, a hard drive failure, stolen laptop, ransomware, to name a few - but they were safe because they had been regularly backing up their files with SpiderOak ONE. Their panic immediately swept into relief, as they realized all their files were still safe and accessible.

But it's not just about the backup that runs quietly in the background, in a way that you might not even notice. SpiderOak ONE also syncs across all of your devices. Drag and drop any file or folder into your  on your computer(s). Backup and sync unlimited devices through your account.

Need access to your files but don't have your device? Simply log in and continue with your day.

So whether you want to store, access or share pictures of your family, a paper you've been working on, your music, movies, or other personal files - use SpiderOak ONE for unparalleled privacy and peace of mind.


Because our software encrypts every piece of data before it ever leaves a computer, we never know the types or content of your files. Everything we store is encrypted end-to-end (at-rest and in-transit). You alone have sole ownership and complete control of the keys to unlock your data. We call this No Knowledge privacy.

From everyday users to Edward Snowden, SpiderOak ONE is recommended as the private alternative to trust with your most important data.
