AVG Technologies said it strives to keep abreast on the latest state-of-the-art security developments by working with security researchers and companies. The initiative is targeted purely on client-side applications, with any server or back-end testing falling outside the program's scope.

AVG had paid out rewards on 32 vulnerabilities as of early February, with an average bounty of $200 over the past three months. Some 230 hackers have joined AVG's bounty program, with 18 security researchers being recognized by Bugcrowd for having reported important security issues.
