Keil MDK

  • Pricing for Essential and Professional subscriptions not disclosed on primary site
  • Customers must contact Arm Developer Tools store for subscription rates

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
