The primary function of a threat intelligence platform in security is to aggregate, analyze, and disseminate information about potential threats to an organization's assets. These platforms help security teams identify vulnerabilities, assess risk levels, and prioritize response efforts effectively. By leveraging data from various sources, threat intelligence platforms provide actionable insights that enable proactive measures against cyber threats. This enhances an organization’s overall security posture and helps in anticipating and mitigating potential attacks before they occur.
