What we catch that your gateway can't.

Legacy email security (SEG)
  • Matches known signatures and patterns
  • Blind to AI-generated, never-seen-before attacks
  • Waves through BEC that passes SPF, DKIM & DMARC
  • Buries analysts in false positives
  • Alerts pile up, hours of manual triage
StrongestLayer
  • Reads every email like a human analyst
  • Catches first-time, one-of-a-kind attacks
  • Flags auth-passed fraud by intent and behavior
  • Under 1% false positives
  • Every alert pre-investigated, closes in minutes

The whole platform, in motion.
