Value props

76Fair

Title, subtitle, hero — do they sell the product's true value?

Castle’s headline sellsStop bots and account abuse at scaleExpose coordinated abuse with Castle's device, email, IP and behavioral intelligence. Enterprise security without the friction.

Working

  • Outcome-first verb: 'Stop bots and account abuse'
  • Subhead names concrete signals: device, email, IP
  • 'Without the friction' hits the buyer tradeoff

Could improve

  • No numbers to anchor 'at scale'
  • Hero is empty gradient; shows nothing
  • No proof stat near strong logo bar
