Dubai-based start-up Crowdfense is offering as much as $3 million for ethical hacking of Android, iOS, Windows and Mac.
The payout is part of a $10m bug bounty program to develop cyber-defence capabilities for popular software. It is the first public programme of its kind to offer a prize that hefty.
Bug hunting, a part of ethical hacking, involves looking for bugs or flaws in code that could be exploited by hackers. It helps software vendors to clean up their code and find mistakes they may have missed.
Crowdfense comprises a global team of cyber-security experts, researchers and lawyers, set to work on some of the world's biggest cyber-defence challenges in order to introduce higher levels of expertise in the market.
"We work only with the best vulnerability researchers, focusing on very select capabilities with a highly structured and scientific approach," said Crowdfense director Andrea Zapparoli Manzoni.
"Now that this originally underground practice has become a strategic high-tech industry, it is necessary to implement good business processes, checks and guarantees for all the parties involved. That is why we built Crowdfense: the market needed a neutral, reliable, law-abiding, process-driven partner to deliver top-quality active cyber-defense capabilities," he added.
The company, which took over a year to establish, aims to get its customers the best return on investments, while protecting nations and citizens from a growing spectrum of threat attacks.
It evaluates, tests and improves state-of-the-art active cyber-defence capabilities.
