Why Integrate Threat Intelligence Feeds into Email Security?
KnowBe4 Blog, Friday, May 15th, 2026
Integrated threat intelligence feeds enable email security systems to proactively detect and respond to evolving AI-driven phishing attacks in real time.
As phishing attacks become more convincing through AI and traditional signature-based defenses struggle to keep pace, organizations need email security systems with integrated threat intelligence feeds that provide real-time context on emerging threats.
Threat intelligence feeds continuously supply indicators tied to active campaigns, including malicious IP addresses, domains, URLs, and file hashes, which when enriched with user behavior and campaign context enable faster detection and response.
Integrating threat intelligence into email security improves proactive threat detection, accelerates response to live threats, increases detection accuracy while reducing false positives, and decreases the operational burden on security teams.
KnowBe4 Cloud Email Security demonstrates this approach by combining integrated threat intelligence with user behavior visibility and adaptive controls, while PhishER Plus extends threat intelligence capabilities through crowdsourced human-reported signals to enable coordinated blocking and remediation across organizations.
