  • They diverge on capability: Icinga covers Forever Free core, Metasploit covers Exploit database.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Icinga

  • An IT team wanting unlimited-scale open source monitoring with no per-host licence fee, running standard Linux distributionsnot Metasploit
  • An organisation on RHEL or SLES that wants officially packaged Icinga builds via the repository subscription rather than building from sourcenot Metasploit
  • A team wanting an SLA-backed vendor support relationship rather than relying on community forums for a production monitoring systemnot Metasploit
  • A company already invested in Prometheus and Grafana wanting to add host and service-level alerting from a compatible open source toolnot Metasploit

Where each one falls short

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

Icinga

  • The free core has no vendor SLA, so production incidents are supported through community channels unless a paid support subscription is purchased
  • Repository access for enterprise Linux distributions like RHEL and SLES is not free, so organisations standardised on those distributions face a real recurring cost most open source monitoring buyers do not expect
  • Enterprise modules are gated behind a separate module subscription, so some functionality demonstrated in marketing material is not part of the free core
  • Self-hosting and operating Icinga requires real Linux and monitoring expertise that a commercial SaaS tool would otherwise absorb, so total cost of ownership includes staff time not captured in the licence price
  • Pricing for the paid subscriptions varies by geographic region and is not published as a single global rate card, complicating budgeting for multinational organisations
  • The web interface and configuration language, while capable, are less immediately polished than a fully commercial tool like PRTG, and initial setup takes longer to reach a usable state

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
