Keys can and do get misplaced in github and in code, often. This is a costly mistake and not always the result of simple human error. Robots are designed to by hackers to crawl for these keys, which are then used illicitly.
On average, it takes two full days to react to this situation. Considering a single hacked key costs companies a minimum of $10,000, and that this situation occurs several time on a daily basis, ignoring this situation is an expensive choice.
Because OneKloud sends out alerts and blocks unforecast spend in real time, while enabling an instant rotation of keys that renders the stolen keys invalid: The potential for keys to be stolen is eliminated alongside the resulting money drain.
