Threat intelligence is evidence-based knowledge, including context, mechanisms, indicators, implications, and actionable advice, about an existing or emerging menace or hazard to assets that can be used to inform decisions regarding the subject’s response to that menace or hazard.
Threat intelligence is gathered through different sources and different tools, however, depending on the functions needed to be served, TI falls into three categories:

• Operational
• Tactical
• Strategic

However, hackers are not the only users and shouldn’t be. The reason behind this amazing tool is to help organizations protect their data. So, just like attackers find information to attack, enterprises can find information to protect. Everything mentioned above (sensitive information, credentials, and so on), if first found by the owner, will be in safe hands. It means that something important has leaked, and you finding this security hole before the hacker, will prevent the risk.
