What is the role of threat intelligence in email security?

The role of threat intelligence in email security is pivotal for adapting security measures according to current threats. This approach enables organizations to stay ahead of potential attackers and respond effectively to emerging threats by leveraging real-time data and insights. Threat intelligence gathers information about the tactics, techniques, and procedures employed by cybercriminals, as well as indicators of compromise that indicate malicious activity. By integrating this intelligence into existing security frameworks, organizations can proactively adjust their defenses, design more effective filtering rules, and implement timely updates to security protocols.

This dynamic response capability ensures that email security systems are not only reactive but also preventative, significantly mitigating the risk posed by evolving threats. Historical data, while useful, lacks the immediacy and relevance necessary for current threat landscapes, which is why relying solely on past threat data does not provide the same level of protection. Similarly, setting up email accounts and advertising products are not connected to threat intelligence—they do not influence security practices in the context of protecting against threats.
