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.; SentinelOne enterprise pricing requires contacting sales
  • They diverge on capability: BigID covers Structured and unstructured scanning, SentinelOne covers AI-powered detection.
  • 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.

SentinelOne

  • Enterprise pricing requires contacting sales
  • Prices shown for 5-100 workstations may differ for larger deployments
  • Purchases must be made through authorized third-party partners

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.

SentinelOne: What is SentinelOne Singularity Complete pricing?

Singularity Complete costs $179.99 per endpoint per year and includes AI-driven endpoint and cloud workload protection, real-time threat detection and response, 14-day data retention, and AI Security Assistant. Pricing shown for 5-100 workstations.

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.

SentinelOne: What features distinguish SentinelOne Commercial from Complete?

Singularity Commercial costs $229.99 per endpoint per year (versus $179.99 for Complete) and adds Identity Detection and Response, 90-day data retention (compared to 14-day), and Managed Threat Hunting services.

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.

SentinelOne: How does partner pricing affect SentinelOne costs?

All SentinelOne purchases are made through authorized third-party partners, and partner pricing may differ from published rates. Customers should verify pricing with their authorized reseller.

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.

SentinelOne: What does SentinelOne Enterprise include?

Singularity Enterprise (custom pricing, contact sales) adds Agentic AI SOC Analyst and Full Visibility and Forensics capabilities to all Commercial features, plus expert-led onboarding and training.
