Cybersecurity professionals understand that no single defense will catch all cyber-threats. Gartner recommends a layered and adaptive security architecture that enables a continuous cycle of “prevent-detect-respond-predict” defense. While this architecture is widely used by cybersecurity vendors, it is noticeably absent in corporate email security. Most organizations still rely primarily on prevention delivered by a secure email gateway (SEG) at the network perimeter.

The secure email gateways has one purpose – to prevent email-borne cyber-attacks from penetrating the enterprise network. However, as threats increase in sophistication and number, the SEG frequently fails.

Organizations need to bolster their perimeter approach to email security. Inbox Detection and Response (IDR) introduces a critical layer of security, right at the cloud mailbox, filling the gaps in detection and remediation left by the SEG. The SEG continues to operate as first layer of defense, removing spam and malware threats as emails pass through it. The IDR layer operates in the mailbox, catching all the phish that got away.

  • Why corporate email in the cloud remains highly vulnerable to cyber-threats
  • How IDR addresses these vulnerabilities
  • Best practices in IDR implementation
