The EFF took a look at 24 companies in total, and three stood out as the worst at protecting your data. Who are the culprits? That would be AT&T, Verizon and WhatsApp. AT&T and WhatsApp only met one of the EFF's criteria, and Verizon met two.
The report wasn't all bad news, though. Nine companies received five-star ratings from EFF. Adobe, Apple, CREDO, Dropbox, Sonic, Wickr, Wikimedia, WordPress.com and Yahoo each met all five pieces of the EFF's data security criteria. You can see every single company's results in the EFF's chart below, and you can access the full report here to read about how your favorite companies faired.
