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.

Splunk Enterprise Security

  • Splunk Enterprise Security is licensed separately from the Splunk platform, so a SIEM deployment needs both
  • Splunk publishes no rate for Enterprise Security and directs buyers to contact a pricing expert
  • UEBA, SOAR and automated threat analysis require the Premier edition rather than Essentials
  • The platform underneath can be billed by ingest volume, workload or activity, so the total cost depends on a pricing model chosen at contract time rather than a list price

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.

Splunk Enterprise Security: How much does Splunk Enterprise Security cost?

Splunk Enterprise Security pricing is not published. The product is available in Essentials Edition with threat detection, investigation, and response capabilities, and Premier Edition with UEBA, SOAR, and Automated Threat Analysis. Customers must contact Splunk sales for pricing quotes on either edition.

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.

Splunk Enterprise Security: What editions of Splunk Enterprise Security are available?

Splunk Enterprise Security offers Essentials Edition with threat detection, investigation, and response capabilities, and Premier Edition which adds UEBA (User and Entity Behavior Analytics), SOAR (Security Orchestration, Automation and Response), and Automated Threat Analysis.

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.

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.
