Using CIRS to Determine If the Threat Is Real

When a Cyren Inbox Security user clicks the red PhishScan button to report a suspicious email, it can fall into one of three categories:

  • Phishing threat detected by CIS, but shouldn’t be
  • Phishing threat not detected by CIS, but should be
  • Nuisance email (not a security threat per se, but unwanted or nuisance emails)

Each threat report is immediately investigated and verified by CIRS experts to determine if the reported threat is real or not. Validated threats may trigger an automatic rescan and remediation of all mailboxes to eradicate a phishing attack for example. When a reported threat is not valid, the incident is immediately resolved and closed.
