To our Customers, Partners & Friends,

Silent Circle has exciting news to share. Due to explosive growth and market demand, Silent Circle has restructured the company to more effectively scale its product portfolio. The “Silent Phone” product suite was sold to Office Tone and continues to operate under the name Silent Circle. Silent Circle’s “GoSilent” product line has been acquired, newly capitalized and rebranded Attila Security.

Attila Security will be led by the original GoSilent management team and engineers. This change will not affect our valued customers or partners in any way. Although our website is currently under construction, you can always reach us at
