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

  • 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

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: 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.

One Identity: Does it include privileged access?

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

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
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: 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.

SentinelOne: What does SentinelOne Enterprise include?
