The short version

  • Only Chainguard has a free tier, so it costs nothing to try first.
  • Each has a real cost: Chainguard containers Catalog at 19,000 USD/year expensive for teams under 10 people; 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.
  • They diverge on capability: Chainguard covers Hardened container images, Dahua Technology covers DSS Pro V8.
  • 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.

Chainguard

  • Containers Catalog at 19,000 USD/year expensive for teams under 10 people
  • Per-image pricing for containers requires custom quotes with no transparency
  • Free tier limited to 5 container images for testing
  • Libraries pricing by ecosystem and developer count lacks transparent per-developer cost
  • VM image catalog pricing opacity makes cost estimation difficult

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.

Answered from the vendors’ own pages

Chainguard: How much is the Chainguard Containers Catalog?

The Containers Catalog is 19,000 USD per year for 10-person engineering teams, providing access to 2,000+ hardened container images.

Source
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.

Chainguard: What SLAs does Chainguard offer?

Chainguard provides contractual CVE remediation SLAs: 7 days for critical vulnerabilities, 14 days for high/medium/low severity, all with priority support.

Source
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.

Chainguard: Can I try Chainguard before purchasing?

Yes. The free tier includes five container images for testing and deployment, allowing hands-on evaluation.

Source
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.

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.
