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.; Yoti age estimation returns a probabilistic range rather than a verified date of birth, so it only works with a safety buffer above the legal threshold and cannot prove an exact age.
  • They diverge on capability: BigID covers Structured and unstructured scanning, Yoti covers Facial age estimation.
  • 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.

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.

Yoti

  • Age estimation returns a probabilistic range rather than a verified date of birth, so it only works with a safety buffer above the legal threshold and cannot prove an exact age.
  • Estimation accuracy varies by demographic and reported error margins widen at the age bands that matter most for eighteen-year thresholds, which pushes borderline users into a document fallback you still have to pay for.
  • Pricing is not published, so buyers cannot compare the cost of an estimation check against a document check without going through sales.
  • Regulatory acceptance of facial estimation differs by jurisdiction, so a method that satisfies Ofcom may not satisfy a regulator elsewhere and multi-market platforms need more than one approach.
  • The reusable digital identity app depends on consumer adoption, which is meaningful in the UK and thin elsewhere, limiting the reusability benefit outside its home market.

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.

Yoti: Does age estimation store my face?

The image is used to produce an estimate and then deleted rather than retained, which is the specific property that makes it usable for age assurance on minors.

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.

Yoti: Is it accepted for UK Online Safety Act compliance?

Facial age estimation is one of the methods regulators have accepted as highly effective age assurance. Confirm the current position with your own counsel for your content category.

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.

Yoti: Can it prove someone is exactly 21?

No. It gives a range. If you need a precise age you need a document or database check, which Yoti also sells.

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.
