Where each one falls short

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

Keil MDK

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

SonicWall

  • Product line page names no price for any firewall model, series or bundled security service
  • Product tiers are segmented strictly by business size (TZ80 for micro-SMBs up to NSsp for large enterprises), so a growing business must migrate hardware series rather than scale within one model
