Where each one falls short

Metasploit

  • The free Framework edition is command line only; the web interface is Pro only
  • Automated exploitation, automated credential attacks and antivirus evading dynamic payloads are restricted to Metasploit Pro
  • Reporting, audit wizards, task chains and closed loop vulnerability validation are Pro only
  • Rapid7 publishes no price for Metasploit Pro and routes buyers to contact sales

Pieces for Developers

  • Requires installing and running a background desktop app rather than being purely cloud-based.
  • Free tier trial of Pro features requires a credit card and reverts after 7 days.
  • Local-first storage means memory is not automatically synced across multiple machines without Enterprise controls.
  • Effectiveness depends on the breadth of integrations enabled, which adds setup overhead.
