For Companies: The Bugbounter platform runs on blockchain so it is transparent, democtratic, secure and agile- thus trustworthy! We provide continuous testing opportunities within the ecosystem, therefore companies discover vulnerabilities that current penetration testing methods would hardly uncover-in a much faster way. Since Bugbounter rewards only the verified successful exploits, the service is highly cost-effective. For Researchers: Our platform gives all the security researchers the same opportunity to challenge their talent, earn rewards and fame. In order to be invited to special bounty programs, researchers would have to go through various levels of vetting processes.
