Encryption App Silent Circle Shuts Down E-Mail Service 'To Prevent Spying'

The business of protecting consumers from prying, government eyes has suddenly become a pre-emptive one for Silent Circle. The communications encryptions firm said Friday that it was shutting down its e-mail service to prevent spying, a day after competitor Lavabit shut down its core email service. Lavabit's founder had suggested in a letter to customers that he had been the subject of a U.S. government investigation and gag order.
