Agentic Index

AirMDR vs UnderDefense (2026)

Both pair an AI analyst with human experts, and both publish a free entry point, which is unusual in this lane.

AirMDR triages 95 percent of alerts in under five minutes across 100 percent of volume with a supervising human team, an always free plan and more than 240 integrations. UnderDefense runs MAXI, a multi agent system handling roughly 80 percent of tier one and two work with full context in two minutes and containment in five, validated by 120 certified engineers, from roughly 11 to 15 dollars per asset a month, documenting 8.5 of 14 against 6. UnderDefense is the deeper service; AirMDR is the easier start.

Choose AirMDR if

  • A genuinely free plan automating alert triage lets you prove the model before any spend.
  • You are an SMB or buying through an MSSP rather than staffing a SOC.
  • Integration breadth out of the box matters more than service depth.

Choose UnderDefense if

  • You want certified engineers validating actions, not just supervising them.
  • Published per asset pricing lets you model cost against your estate.
  • On premise for closed, sovereign or air gapped environments is a hard requirement.
