Privacy should not stop at software. Silent Circle made security its whole product: the Blackphone 2 shipped with SilentOS, encrypted calls and hardened permissions for people who take data seriously. It would be odd to lock down your traffic yet leave your display readable to anyone alongside you, which is why a two-way privacy filter is the natural Silent Circle screen protector. Prefer another finish? Crystal-clear, anti-glare and anti-shock versions are shaped just as precisely for Blackphone displays. Find your device with the filters, then let the comparison tool weigh the options for you.
