After more than four years of prep, the security startup has launched a service that claims to have solved the burden of cryptographic key management.

In late 2010, Adam Ghetti—founder and CTO of the security startup Ionic Security that exited so-called “stealth mode” on Tuesday—started building a tool that would allow him to have more control over his information across services like Twitter, Facebook, and Dropbox. He was tired, he says, of implicitly trusting them, of feeling as though he had no insight into what they were doing with his data. He called the program “social fortress.”
