The short version

  • They diverge on capability: BigID covers Structured and unstructured scanning, Mark43 covers Computer-Aided Dispatch.
  • Prices and features above were last checked on 31 August 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.

Mark43

  • No published pricing on homepage; sales contact required for all cost details
  • Only reference to pricing is 'early bird pricing' for 2027 conference registration
  • No transparent pricing structure visible for public evaluation

Answered from the vendors’ own pages

BigID: What does BigID cost?

Source
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.

Mark43: What payment methods or financing options does Mark43 offer?

No information about payment methods or financing options is disclosed on the public homepage. Pricing and payment details are handled through direct sales consultations.

Source
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.

Mark43: Are there volume discounts or specialized pricing for different agency sizes?

Mark43 website does not disclose any volume pricing, per-user costs, or specialized rates for agencies of different sizes. All pricing inquiries require direct contact with sales team.

Source
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.
