The short version

  • They diverge on capability: One Identity covers Identity Manager, SentinelOne Singularity covers Behavioral AI.

Where each one falls short

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

One Identity

  • The portfolio is assembled from separate acquisitions, so components are separately licensed, separately administered and do not present one console, which raises operational cost.
  • Identity Manager implementations are customisation-heavy and commonly run over a year, with the services spend exceeding the licence cost in the first year.
  • Quest has changed private equity ownership more than once since the Dell separation, and buyers should ask directly about product investment commitments before signing a multi-year deal.
  • Product documentation and support sit behind a customer portal, which makes independent evaluation before purchase harder than with vendors that publish openly.
  • The cloud-native and developer experience trails the pure-play identity vendors, so organisations moving decisively to SaaS applications find the on premises heritage becomes a constraint rather than an asset.

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

One Identity: Is One Identity the same company as Quest?

Yes. One Identity is Quest Software's identity and access management business unit, not a separate vendor.

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
One Identity: Does it include privileged access?

Safeguard provides it, but it is licensed separately from Identity Manager. Neither includes the other.

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
One Identity: Why choose this over SailPoint or Saviynt?

Almost always because of Active Directory depth via Active Roles or an appliance requirement for privileged sessions. For cloud-first estates the specialists are the stronger choice.

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
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.
