Security firm iDefense has doubled the cash rewards on offer to researchers who spot software bugs after a rival company started its own bounty payment scheme.
The company announced an immediate doubling of the standard pricing structure covering reports submitted under its three-year-old vulnerability contributor programme, while incentive and retention payments designed to reward regular contributors will also be boosted.
A new growth reward programme has been added to the scheme, offering a further bonus for those whose vulnerability reports increase year-on-year.
The company, acquired by VeriSign in a $40m (£22.8m) deal earlier this month, announced its new bounty rates just a day after rival firm Tipping Point announced its own cash for bug reports scheme, as the competition to identify security vulnerabilities hots up.
The iDefense retention programme, which rewards the top five contributors each year, will now pay out a $10,000 prize to its best contributor, while the top contributor each quarter will scoop $5,000.
Contributors making submissions to iDefense for at least two years will be able to apply for payments under the growth programme as well.
