The short version

  • Only Nagios XI has a free tier, so it costs nothing to try first.
  • Each has a real cost: Nagios XI free Edition caps at 7 nodes or 100 services, whichever limit is hit first; Zeta it competes against card processors with decades of production track record, and in card processing an outage is a public event, so a shorter operational history is a genuine risk factor rather than a technicality.

Where each one falls short

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

Nagios XI

  • Free Edition caps at 7 nodes or 100 services, whichever limit is hit first
  • Standard Edition is licensed per node count, starting at $2,595 for 100 nodes and rising to $14,995 for 1,000 nodes
  • Enterprise Edition, which adds capacity planning and SLA reporting, is sold as an add-on starting at $4,690 for 100 nodes on top of the base license
  • Sitewide Edition for large distributed environments has no published price and requires contacting sales

Zeta

  • It competes against card processors with decades of production track record, and in card processing an outage is a public event, so a shorter operational history is a genuine risk factor rather than a technicality.
  • Contracts are enterprise scale and quoted with volume minimums, which puts it out of reach of small issuers who would otherwise benefit most from modern tooling.
  • A card portfolio migration runs twelve to twenty four months at minimum, during which the issuer runs two platforms and pays for both.
  • Zeta is a processor rather than a licence holder, so network membership, BIN sponsorship and regulatory obligations remain entirely with the issuer.
  • Public references for large live United States production volumes are fewer than the announcements imply, so diligence should insist on active account counts and uptime history rather than partnership press releases.
