Kim Bubello for TIME Our personal information, stored by corporations like Google and Yahoo, seems more vulnerable than ever to hacks and leaks. One way to help keep it private is by storing it yourself using an email attached to a custom domain name; Helm CEO Giri Sreenivas calls email the “core of your online identity” through which you access nearly “every account that you have online.” For $499, the Helm Personal Server is a service and device that gives you private email and stores it securely, along with files, contacts and calendars. Its first two manufacturing runs have already sold out. —Tara Law
