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.

Splunk Enterprise Security

  • Splunk Enterprise Security is licensed separately from the Splunk platform, so a SIEM deployment needs both
  • Splunk publishes no rate for Enterprise Security and directs buyers to contact a pricing expert
  • UEBA, SOAR and automated threat analysis require the Premier edition rather than Essentials
  • The platform underneath can be billed by ingest volume, workload or activity, so the total cost depends on a pricing model chosen at contract time rather than a list price

Answered from the vendors’ own pages

The product is available in Essentials Edition with threat detection, investigation, and response capabilities, and Premier Edition with UEBA, SOAR, and Automated Threat Analysis. Customers must contact Splunk sales for pricing quotes on either edition.

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

Splunk Enterprise Security: What editions of Splunk Enterprise Security are available?

Splunk Enterprise Security offers Essentials Edition with threat detection, investigation, and response capabilities, and Premier Edition which adds UEBA (User and Entity Behavior Analytics), SOAR (Security Orchestration, Automation and Response), and Automated Threat Analysis.

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.
