The short version

  • Only Milestone XProtect has a free tier, so it costs nothing to try first.
  • Each has a real cost: Diligent the platform is an assembly of acquisitions, with the analytics engine from ACL, risk from Rsam, ethics and third-party diligence from Steele and the board portal from Diligent itself, so cross-module reporting and consistent user experience should be tested in a proof of concept rather than assumed.; 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: Diligent covers Diligent Boards, Milestone XProtect covers Open device support.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Diligent

  • The platform is an assembly of acquisitions, with the analytics engine from ACL, risk from Rsam, ethics and third-party diligence from Steele and the board portal from Diligent itself, so cross-module reporting and consistent user experience should be tested in a proof of concept rather than assumed.
  • Pricing is unpublished and consistently at the top of the market, and organisations that need only one capability, a board portal or an audit analytics tool, generally pay less and get more from a specialist.
  • Renewal leverage is weak once the board portal is embedded, because directors are the least willing user group to be migrated and that dependency is well understood by the vendor at renewal time.
  • The analytics engine expects real data skills, and audit teams without an analytics-capable member typically use a fraction of what they licensed while paying for all of it.
  • Module-by-module implementation means the promised single view of governance and risk usually arrives years after the first purchase, if the later modules are ever funded.

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

Diligent: Is Diligent One the same product as Galvanize?

It contains it. Diligent bought Galvanize, the ACL and Rsam merger, for around one billion dollars in April 2021, and its audit analytics and risk modules are that heritage rebranded into Diligent One.

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.

Diligent: What does Diligent cost?

Not published. It is quoted by module and user, and board portal seats are priced differently from GRC seats. Expect an annual or multi-year enterprise agreement.

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.

Diligent: Can you buy just the board portal?

Yes, Diligent Boards is sold on its own and is the most common entry point. The GRC modules are separate purchases.

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.

Diligent: Does it replace a SOC 2 automation tool?

No. Diligent is aimed at enterprise audit, risk and governance, not at automated evidence collection for security certifications.

Milestone XProtect: Who owns Milestone?

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