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.; Resolver kroll ownership since 2022 means the product is sold alongside risk consulting services, so buyers who want software with no services attach should expect that conversation and should price the licence separately in negotiation.
  • They diverge on capability: BigID covers Structured and unstructured scanning, Resolver covers Incident management.
  • 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.

Resolver

  • Kroll ownership since 2022 means the product is sold alongside risk consulting services, so buyers who want software with no services attach should expect that conversation and should price the licence separately in negotiation.
  • Configuration flexibility comes at the cost of implementation time, with deployments commonly running several months and typically requiring vendor or partner services, so the first-year cost is well above the annual licence.
  • Module-based pricing means the platform gets expensive quickly once you add audit, compliance and continuity to a security-led purchase, and modules bought later rarely carry the discount of the original deal.
  • The IT and cyber compliance side is thinner than dedicated tools, so organisations chasing SOC 2 or ISO 27001 evidence automation will find it does not replace a Drata or Vanta.
  • Reporting is capable but the drag and drop builder has a real learning curve, and organisations that do not train an internal administrator end up raising support tickets for changes that should be self-service.

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.

Resolver: Who owns Resolver?

Kroll, which acquired it in 2022. It is marketed as a Kroll business and sold alongside Kroll risk and investigations services.

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.

Resolver: What does Resolver cost?

Pricing is not published. It is quoted by module and user count on an annual or multi-year enterprise agreement, with implementation charged separately.

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.

Resolver: Is Resolver a SOC 2 compliance tool?

No. It is a risk, incident and investigations platform. Automated evidence collection for security certifications is not its strength.

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.

Resolver: How long does implementation take?

Months rather than weeks for a multi-module deployment, and most customers use vendor or partner services to configure it.
