Which should you choose?

Choose CyCognito if

  • it matters most to you that it proves exploitability (9/10)
  • it matters most to you that it finds the unlisted estate (9/10)

Choose CyCognito if you have no reliable asset list and want proof and a verified fix for each finding. Look elsewhere if you need exposures blocked at the edge before the patch lands.

Choose Tenable ASM if

  • it matters most to you that it fits the enterprise stack (9/10)
  • it matters most to you that it finds the unlisted estate (7/10)

Choose Tenable ASM if Tenable One is already your exposure platform. Look elsewhere if you want an ASM tool that proves and contains exposures on its own.
