The short version

  • Each has a real cost: Qualys VMDR licensing is per asset and each capability is its own subscription, so patch management, endpoint detection, web application scanning, container security and policy compliance are separate line items, and the platform demonstrated in a proof of concept is rarely the platform in the quote.; Rhombus Systems the per-camera annual licence never ends and a camera without an active licence stops working, so the total cost over a ten-year hardware life is several times the hardware price.
  • They diverge on capability: Qualys VMDR covers Cloud Agent, Rhombus Systems covers On-camera storage.
  • 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.

Qualys VMDR

  • Licensing is per asset and each capability is its own subscription, so patch management, endpoint detection, web application scanning, container security and policy compliance are separate line items, and the platform demonstrated in a proof of concept is rarely the platform in the quote.
  • Ephemeral cloud instances consume asset entitlement until they age out of inventory, so an autoscaling group that creates and destroys hosts hourly can burn licence capacity on machines that existed for minutes, and controlling that means tuning purge policies rather than tuning the cloud.
  • Authenticated scanning produces materially better results than unauthenticated, but it requires storing and rotating privileged credentials for every target platform, which is a security project in its own right, and teams that skip it receive reports full of unconfirmed potential findings that nobody trusts.
  • The console is a set of modules with separate interfaces, search syntaxes and report engines, so an analyst moving between vulnerability management, policy compliance and web application scanning learns each one, and cross-module reporting usually ends in a spreadsheet or a script against the API.
  • The tool surfaces findings far faster than any organisation can remediate them, and it does not solve the ownership problem: without an agreed prioritisation policy and a named owner in IT operations, a first scan producing tens of thousands of findings becomes a dashboard that everyone learns to ignore.

Rhombus Systems

  • The per-camera annual licence never ends and a camera without an active licence stops working, so the total cost over a ten-year hardware life is several times the hardware price.
  • Cameras must be Rhombus, so there is no reuse of existing IP cameras and migrating away means replacing every device rather than changing software.
  • Cloud archiving is priced separately by retention and stream count, and long retention on multisensor cameras runs into five figures per camera, which can dwarf everything else in the quote.
  • On-camera storage is the default retention, so a camera physically stolen or destroyed takes its unarchived footage with it unless cloud archiving was paid for on that camera.
  • Analytics and integrations are good for mid-market needs but shallower than a dedicated enterprise VMS with a large third-party ecosystem, so specialist requirements like advanced LPR or forensic search hit limits.

Answered from the vendors’ own pages

Qualys VMDR: Agent or scanner: which do I need?

Usually both. The agent covers endpoints and servers you control and gives continuous data; scanners cover devices you cannot install an agent on, such as network gear, printers and appliances, and provide the external perimeter view.

Rhombus Systems: Do I need an NVR or a server?

No. Cameras record on board and connect directly to the cloud console, which is the main operational reason organisations pick it.

Qualys VMDR: Does it patch as well as detect?

Yes, through the Patch Management module, which is a separate subscription using the same agent. Core VMDR detects and prioritises but does not deploy fixes.

Rhombus Systems: What does the licence cost?

Roughly $149 per camera per year for Professional and about $199 for Enterprise, typically sold in one, three, five or ten year terms.

Qualys VMDR: How are assets counted for licensing?

By the number of assets in inventory, which includes cloud instances and containers depending on the modules in use. Short-lived cloud assets count until they are purged, so purge settings directly affect what you consume.

Rhombus Systems: Is cloud storage included?

No. On-camera storage is the default. Cloud archiving is a separate charge priced by retention duration and number of streams.

Qualys VMDR: Can I keep the data in a specific region?

Yes. Qualys operates several regional platform instances and you choose which one your subscription lives on. Moving between them later is not trivial, so decide before onboarding.

Rhombus Systems: Can I use my existing cameras?

No. The platform works only with Rhombus hardware, which is the trade-off for the zero-server architecture.

Qualys VMDR: Does it scan web applications?

Web Application Scanning is a separate module licensed per application, not part of core VMDR, and it is a dynamic scanner with the usual limits around authenticated flows in single-page applications.
