Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Clerk

  • Pricing scales with monthly retained users, which can grow expensive quickly for consumer apps with large user bases.
  • Enterprise SSO connections beyond the first are billed as add-ons, adding cost for larger organizations.
  • The Business tier's extra dashboard seats cost $20/month each, which adds up for larger teams.
  • Enterprise-tier features like the 99.99% uptime SLA require annual contracts rather than flexible monthly billing.

Rapid7 InsightVM

  • InsightVM is now sold inside Exposure Command rather than as a standalone product
  • Rapid7 states pricing is not publicly listed and is provided by custom quote based on the customer's environment
  • Billing counts billable assets including devices, software, identities, cloud compute instances and applications, so the asset count grows faster than a device inventory suggests
  • Cloud security, compliance, infrastructure as code scanning and application security testing require the Ultimate package rather than Essentials
  • Volume discounts are described as commonly available for larger asset counts, so smaller buyers pay the higher unit rate
