The short version

  • Each has a real cost: Dahua Technology dahua is named under NDAA Section 889 and listed on the FCC Covered List, so the US federal government cannot procure its video surveillance equipment and cannot contract with entities that use it, which disqualifies most organisations with any federal contracting ambition regardless of how good the software is.; 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.
  • They diverge on capability: Dahua Technology covers DSS Pro V8, Qualys VMDR covers Cloud Agent.
  • 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.

Dahua Technology

  • Dahua is named under NDAA Section 889 and listed on the FCC Covered List, so the US federal government cannot procure its video surveillance equipment and cannot contract with entities that use it, which disqualifies most organisations with any federal contracting ambition regardless of how good the software is.
  • Rules adopted by the FCC in late 2025 gave the Commission authority to revoke equipment authorisations already granted, so equipment that is legal to sell today may not be tomorrow and a multi-year rollout carries regulatory risk the vendor cannot indemnify.
  • Sourcing has degraded sharply: new equipment, replacement parts and system expansions are increasingly difficult to obtain through compliant US distribution and major retailers have removed listings, so an installed estate faces a spares problem long before end of life.
  • Any organisation that later wins or bids for federal work, or supplies a federal contractor, must audit and replace Dahua equipment across all its facilities under Section 889(a)(1)(B), turning a cheap installation into an expensive forced rip-out.
  • Beyond procurement law, insurers, auditors and enterprise customers increasingly treat Chinese-manufactured surveillance as a supply chain finding in its own right, so the reputational cost lands even where the legal prohibition does not.

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.

Answered from the vendors’ own pages

Dahua Technology: Can a US federal agency buy Dahua?

No. Dahua is explicitly named under NDAA Section 889, so federal agencies cannot procure or obtain its video surveillance equipment, including OEM-rebadged versions.

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.

Dahua Technology: Can a private US company use Dahua cameras?

Section 889 does not directly regulate private companies without federal contracts, and existing installations are not required to be removed. But the moment the company bids for federal work or supplies a federal contractor, Section 889(a)(1)(B) makes the installed equipment a problem.

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.

Dahua Technology: Is existing Dahua equipment banned?

No. The prohibition on new authorisations does not apply retroactively to equipment authorised before February 2023, and legacy systems may remain in use. New purchases and expansions are the restricted part.

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.

Dahua Technology: Is Dahua available outside the United States?

Yes, and it remains one of the two largest manufacturers globally, though a number of other countries have introduced their own restrictions on government use.

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.

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.
