SpiderOak is an US based[1] online backup and file hosting service that allows users to access, synchronize and share[2] 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.[3] 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.[4] As of 2015, SpiderOak's source code is not available.[5]

SpiderOak distinguishes itself from its competition in provision of encryption,[6] in provision for syncing files and folders across multiple devices, and in automatic de-duplication of data.[7]

SpiderOak was rated "Awesome" by MacLife magazine in 2009[8] and also was made an Editor's Choice by Computer Shopper magazine in May 2009.[9] In a July 2014 interview, former NSA contractor Edward Snowden recommended SpiderOak over Dropbox, citing its better protection against government surveillance.[10]

History

SpiderOak was founded in 2007 by Ethan Oberman and Alan Fairless as a zero knowledge private backup program.[11] In 2013, SpiderOak began developing Crypton (framework), "a JavaScript framework for building applications where the server doesn't know the contents it's storing on behalf of users."[12] Crypton is an Open Source project allowing developers to easily add encryption security to mobile applications.[13] By mid-2014, SpiderOak neared 1 million users.

SpiderOak is headquartered in Chicago and currently employs 42 staff, headed by CEO Ethan Oberman.[10] In 2013, SpiderOak opened offices in San Francisco and Kansas City, and hires remote employees inside and outside of the US.[14][15]

Main features

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[3]
  • 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.[16] This claim, however, cannot be confirmed due to the client being closed source[17]
  • Unlimited devices[18]
  • A layered approach to encryption, using a combination of 2048-bit RSA and 256-bit AES[4]
