Thanks for the vulnerability report! The report was responsible and detailed enough to let us quickly verify and diagnose the issue, understand its impact, and fix it quickly. Ayan was reacting in lightning speed once I contacted him. He explained the issue to me very clear and provided a comprehensive amount of possible solutions. This was really great service, thanks so much!
