The short version

  • Each has a real cost: BigID pricing scales with data sources and volume, so the cost rises exactly as the estate you need to scan grows, and the modules shown in a demo, including AI security posture and headless deployment, are frequently separate licences that appear only in the final quote.; 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: BigID covers Structured and unstructured scanning, Dahua Technology covers DSS Pro V8.

Where each one falls short

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

BigID

  • Pricing scales with data sources and volume, so the cost rises exactly as the estate you need to scan grows, and the modules shown in a demo, including AI security posture and headless deployment, are frequently separate licences that appear only in the final quote.
  • Scanning large unstructured estates is slow and computationally expensive, so most organisations sample rather than scan everything, which reintroduces uncertainty into the very question they bought the tool to settle.
  • Classification accuracy on messy unstructured content requires tuning, and out of the box false positives on things like reference numbers create a large triage backlog that a small governance team cannot clear.
  • It discovers and reports but does not remediate, so realising value requires a separate process and often separate tooling to actually delete, restrict or move the data it flags.
  • It is built for large enterprises and both the price and the administrative overhead are disproportionate below a few thousand employees, where a lighter DSPM tool covers the security use case for far less.

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

BigID: What does BigID cost?

It is quoted by data source count and volume. Reported contracts run from roughly 15,000 to 175,000 US dollars a year, and add-on modules such as AI security posture are licensed on top.

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.

BigID: Does it handle unstructured data?

Yes, and that is its main advantage. It classifies data in files and shares and correlates findings back to individuals, not just to data types.

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.

BigID: Will it delete the data it finds?

Not by itself in most deployments. It identifies and routes findings; deletion and remediation happen through your own processes or connected systems.

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.

BigID: Is it a privacy tool or a security tool?

Both are sold from the same discovery core. Buyers increasingly come from security wanting data security posture management rather than from legal wanting privacy.

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.
