Kind of …. but instead of personal computers or personal devices our focus is on protecting websites. Hackers, well their automated bots, find vulnerable sites by searching for sites with known vulnerabilities (via google dorks for instance) and then their bots can infect and take over those sites in just a matter of a few seconds.
SharkGate is a way of protecting your site from being broken into by the hackers by standing in the way and blocking them. Hacking of websites is rampant due to the large money to be gained from such malicious activities. For example, see this transparency report from Google about sites it has found that are currently infected.
