The short version

  • Only Milestone XProtect has a free tier, so it costs nothing to try first.
  • Each has a real cost: Cortex pricing is quote only, so a platform team cannot build a business case or compare against the true cost of self-hosted Backstage without entering a sales cycle first.; 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.
  • They diverge on capability: Cortex covers Service catalogue, Milestone XProtect covers Open device support.
  • 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.

Cortex

  • An organisation where ownership of production services is genuinely unknown after reorganisations or acquisitionsnot Milestone XProtect
  • Enforcing production readiness standards on new services at creation time rather than at incident reviewnot Milestone XProtect
  • Replacing a self-hosted Backstage that is consuming a full-time engineer or two just to stay upgradednot Milestone XProtect

  • A city or transport operator running tens of thousands of cameras across federated sitesnot Cortex
  • An enterprise with mixed legacy camera brands that refuses to standardise on one manufacturernot Cortex
  • A critical infrastructure site needing failover recording servers and tamper-evident evidence exportnot Cortex
  • An integrator building a bespoke security application on top of an open VMS platformnot Cortex

Where each one falls short

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

Cortex

  • Pricing is quote only, so a platform team cannot build a business case or compare against the true cost of self-hosted Backstage without entering a sales cycle first.
  • The catalogue is only as accurate as the metadata you supply, so an organisation with inconsistent repository conventions spends its first quarter cleaning data before any scorecard means anything.
  • Scorecards create political friction: publishing a per-team grade turns an engineering standard into a performance metric, and teams will game the rules rather than fix the underlying issue.
  • It is closed source and hosted, so organisations with strict data residency or air-gap requirements have limited options compared with running Backstage themselves.
  • Value scales with organisation size, so a company with fifty engineers and thirty services will find the catalogue tells them nothing they did not already know while still paying an enterprise contract.

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.

Answered from the vendors’ own pages

Cortex: How is Cortex different from Backstage?

Backstage is an open source framework you build and staff. Cortex is a hosted product with scorecards and initiatives out of the box and no platform team required to keep it running.

Milestone XProtect: Is XProtect really free for small sites?

Essential+ is free for up to eight cameras with no recording time limit, but it comes with no vendor support and no multi-server capability.

Cortex: Is pricing published?

No. Cortex requires a sales conversation and prepares a custom proposal.

Milestone XProtect: Are licences perpetual or annual?

Device licences are perpetual. The annual cost is Care Plus, the support and software update contract, which you need to stay on current versions.

Cortex: Can it self-host?

It is offered as a hosted product; on-premise arrangements are handled through sales rather than published.

Milestone XProtect: What happens if I do not renew Care Plus?

The system keeps recording, but you stop getting version upgrades, and over a few years that blocks you from adding newer cameras.

Cortex: What is the main adoption risk?

Bad or missing service metadata. The catalogue and every scorecard on top of it inherit whatever quality your repositories already have.

Milestone XProtect: Who owns Milestone?

Canon. The portfolio also includes BriefCam analytics and Arcules cloud video, with Arcules replacing Milestone Kite from January 2025.
