Once thought of as the "security-minded" Dropbox and Google Drive competitor, SpiderOak has now fully rebranded itself as "Space Cyber Security Solutions for Hybrid Space". This is no window dressing, either - the company is optimizing its software for space missions. It no longer has customers, it has "mission partners". The company has a Senior VP of Space and a Space Advisory Board.
For its existing, more "down to Earth" customers, the company directs you to its legacy One Backup product over at the https://crossclave.com/one/ website. Ultimately, it seems like sales, marketing, and the ICP have changed more than the product itself (aside from some new software certification goals, of course).
