Already 14 bug finders have been rewarded under the bug bounty programme.
Silent Circle and Blackphone have jointly announced the launch of their bug bounty programme which is designed to encourage independent developers to find vulnerabilities within the platform.
Both the companies will offer a standard reward or bounty of $128 per bug, depending upon the severity of the vulnerability reported.
According to the terms, researchers have to submit a valid report and must be the first to report the vulnerability and must not publically disclose the vulnerability before reporting them to the company.
The Blackphone bug bounty programme includes update servers, PrivatOS, and associated web portals, and the Silent Circle programme includes network services client apps, web sites, cloud infrastructure and web services.
Blackphone and Silent Circle CSO Dr. Daniel Ford said: "We have high expectations for security and privacy."
"In order to deliver on our expectations we must continually build a strong relationship with the security research community."
Blackphone CEO Toby Weir-Jones said: "Ensuring the privacy of its users is at the core of what do, making security of the utmost importance."
"By launching our Bugcrowd bug bounty programme, both companies are assuring their customers that their smartphone and communication software is subjected to the latest testing and assessment techniques, while providing a form of compensation for successful contributors."
