Google handed out a record amount of bug bounty prize money in 2019 as part of its Vulnerability Reward Programs.

In an announcement, the company revealed it rewarded security researchers who found kinks in its defenses $6.5 million last year — that’s nearly twice the amount Google paid for bug bounties in 2018 which amounted to a total of $3.4 million. This brings the total amount of rewards given since 2010 to $21 million.
