  in internet attack surface management, continuously discovering and monitoring an
  organization''s internet-connected assets to find exposures and unmanaged risk. The
  company was backed by IVP, Susa Ventures, and Y Combinator, and was acquired by Palo
  Alto Networks in 2020. Its technology now ships as Cortex Xpanse, part of the Palo
  Alto Networks Cortex platform, and the expanse.co domain 301-redirects to the Cortex
