SEER™ Threat Detection Technology

Patented behavioral phishing detection and machine learning to detect unknown threats with unmatched accuracy.

Detect More Evasive Threats

SlashNext’s patented SEER™ technology brings cloud-scale resources to real-time, multi-vector, multi-payload phishing threat detection. The SEER approach sees through more evasion tactics and detects previously unknown, zero-hour threats missed by URL inspection and domain reputation analysis methods.

SEER technology addresses:

  • Phishing and social engineering payloads beyond fake login pages
  • Shortened links
  • Multiple URL redirects / forwards
  • Other types of URL obfuscation
  • Multi-stage attacks requiring user interaction, even captchas
  • Use of compromised websites and legitimate hosting infrastructure
