The short version

  • Each has a real cost: Relativity quote-only and expensive, typically billed on data volume, so costs escalate with matter size; SentinelOne enterprise pricing requires contacting sales
  • They diverge on capability: Relativity covers Large-scale processing, SentinelOne covers AI-powered detection.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Relativity

  • Quote-only and expensive, typically billed on data volume, so costs escalate with matter size
  • Complex enough that certified specialists are a job title, which is a real staffing cost
  • Considerable overkill for small matters, where lighter self-service tools are far cheaper

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
