SpiderOak is an American online backup and file hosting service that allows users to access, synchronize and share data using a cloud-based server. SpiderOak is accessible through an app for Windows, Mac and Linux computer platforms, and Android, N900 Maemo and iOS mobile platforms. SpiderOak allows users to back up any given folder on their computer. According to SpiderOak, the software uses encrypted cloud storage and client-side encryption key creation, so SpiderOak employees cannot access users' information. Some components of SpiderOak are open-source, and as early as 2009 the company announced their intent for the client to be fully open-source in the future. As of 2015, SpiderOak's source code is not available.
SpiderOak distinguishes itself from its competition in provision of encryption, in provision for syncing files and folders across multiple devices, and in automatic de-duplication of data. SpiderOak offers free accounts to users who do not exceed a maximum size, and premium accounts for a monthly fee. SpiderOak also offers referral discounts.
SpiderOak was rated "Awesome" by MacLife magazine in 2009 and also was made an Editor's Choice by Computer Shopper magazine in May 2009. In a July 2014 interview, former NSA contractor Edward Snowden recommended SpiderOak over Dropbox, citing its better protection against government surveillance.
SpiderOak is headquartered in Chicago and currently employs 42 staff, headed by CEO Ethan Oberman. In 2013, SpiderOak opened offices in San Francisco and Kansas City, and hires remote employees inside and outside of the US.
Main features comprise:
- All data accessible in one de-duplicated location
- Configurable multi-platform synchronization
- Preserve all historical versions and deleted files
- Share folders in web ShareRooms with RSS notifications
- Retrieve files from any internet-connected device
- Claimed "zero-knowledge" data encryption if you only use the desktop client, that is, no sharing, web-access, or mobile access. This claim, however, cannot be confirmed due to the client being closed source
- Unlimited devices
- A layered approach to encryption, using a combination of 2048-bit RSA and 256-bit AES
