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 Singularity deployment and configuration requires professional services ($5,000 to $25,000)
  • They diverge on capability: BigID covers Structured and unstructured scanning, SentinelOne Singularity covers Behavioral AI.
  • 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 Singularity

  • Deployment and configuration requires professional services ($5,000 to $25,000)
  • Optional modules like Ranger and Vigilance add to total cost of ownership
  • Complex pricing tiers make budgeting difficult for large deployments

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 Singularity: What does SentinelOne Singularity XDR cover?

Singularity XDR unifies detection and response across endpoints, cloud, identity, network, and mobile, providing centralized visibility and automated response across all attack surfaces.

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 Singularity: How does SentinelOne correlate data across security tools?

Singularity normalizes data from endpoints, identity, cloud, and third-party security tools into a unified data layer, enabling automatic correlation of signals without manual integration.

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 Singularity: Can SentinelOne integrate with existing security tools?

Yes, Singularity Marketplace provides pre-built, one-click integrations with email, network, firewall, and SaaS security tools, avoiding vendor lock-in while extending detection capabilities.

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 Singularity: What is the pricing model for SentinelOne Singularity?

SentinelOne pricing ranges from $5.83 to $17.50 per endpoint per month across five tiers, with optional add-on modules and enterprise pricing available on request.
