  • They diverge on capability: Milestone XProtect covers Open device support, Nessus covers Vulnerability scanning.

Where each one falls short

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

Milestone XProtect

  • Care Plus is presented as optional but is not in practice: without it, perpetual licences stop receiving version upgrades and eventually you cannot add a current camera because your frozen version does not support it.
  • Per-device licensing means multi-sensor and multi-imager cameras consume several licences each, so a headline camera count badly understates the true licence cost of a modern design.
  • It is Windows only for servers and needs a properly designed server and storage architecture, so the software price is a fraction of a project that also needs recording servers, storage and an integrator.
  • Complexity requires trained staff or a certified integrator; organisations that install it without either end up running a large deployment on default settings and never using the features they paid for.
  • Milestone retired Kite from its portfolio in favour of Arcules from January 2025, which stranded buyers who had standardised on Kite and is a reminder that the cloud side of the portfolio has changed direction more than once.

Nessus

  • Nessus Professional is $4,790 for one year, with no free or low cost commercial tier
  • Multi year terms are the only discount route, at $9,330.95 for two years and $13,637.54 for three
  • It is a single user scanner, so team workflows mean migrating to another Tenable product
  • Tenable One vulnerability management is priced separately, starting at $3,500 a year for 100 assets
