Program Rules

Maintaining top-notch security is a group effort and Silent Circle encourages independent security researchers to help us spot potential issues. To recognize such efforts and the important role they play in keeping the Silent Circle ecosystem safe we offer a bounty for reporting qualifying security vulnerabilities.

Please review the following program rules before you report a vulnerability. By participating in this program, you agree to be bound by these rules.


Silent Circle may provide rewards to eligible reporters of qualifying vulnerabilities. The standard reward is $128.00 USD. Reward amounts may vary depending upon the severity of the vulnerability reported. Silent Circle will determine, in its discretion, whether a reward should be granted and the amount of the reward.

We are pleased to thank every researcher who submits valid reports that help us improve the security of the Silent Circle. However, only those that meet the following eligibility requirements may receive a reward:

• You must be the first reporter of a vulnerability;
• The vulnerability must be a qualifying vulnerability (see Scope);
• We can’t be legally prohibited from rewarding you;
• You may not publicly disclose the vulnerability prior to our resolution;
• Not be employed by Silent Circle or its subsidiaries or related entities.
