The short version

  • Each has a real cost: Semperis scope is limited to Active Directory, Entra ID and Okta, so an organisation whose critical identity lives elsewhere gets little from it, and the recovery value declines in direct proportion to how much has already moved off on-premises AD.; SentinelOne enterprise pricing requires contacting sales
  • They diverge on capability: Semperis covers Active Directory Forest Recovery, 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.

Semperis

  • Scope is limited to Active Directory, Entra ID and Okta, so an organisation whose critical identity lives elsewhere gets little from it, and the recovery value declines in direct proportion to how much has already moved off on-premises AD.
  • The licence buys tooling, not a proven runbook: forest recovery is only worth what your last rehearsal demonstrated, and a plan that has never been executed end to end in a lab is an untested assumption regardless of what was purchased.
  • It overlaps with backup and directory management products from Quest, Veeam, Commvault and others, so the buyer must argue internally why a dedicated product is needed alongside a backup contract that already claims to protect Active Directory.
  • Running Directory Services Protector well requires someone who understands AD internals, replication metadata and Tier 0 attack paths, and without that person the alerts on privileged changes are either ignored or auto-reverted in ways that break legitimate administration.
  • Licensing is driven by identity object counts, so directories carrying years of stale user accounts and service principals pay for objects that should have been deleted, and the cleanup project that would reduce the bill is the one nobody has time for.

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

Semperis: Does this replace my backups?

No. It replaces the Active Directory recovery procedure specifically. You still need backups for everything else, and the point of Semperis is that a generic system-state backup of a domain controller is a poor way to recover a forest because it restores the operating system along with whatever compromised it.

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.

Source
Semperis: Is it useful if we are cloud-only on Entra ID?

Partly. Directory Services Protector covers Entra ID and Okta for change tracking and posture, but the forest recovery product, which is the strongest reason to buy, applies to on-premises Active Directory. A genuinely cloud-only organisation should weigh it against Microsoft's own tooling.

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
Semperis: Are Purple Knight and Forest Druid really free?

Yes, both are free downloads with no licence requirement, and they are widely used by organisations that are not Semperis customers. They are also, transparently, the top of the sales funnel.

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.

Source
Semperis: How long does forest recovery actually take?

The honest answer is whatever your rehearsal took. The vendor's case is hours instead of days, and automation genuinely removes most manual steps, but the number that matters for your board is the one from a test in your own environment.

SentinelOne: What does SentinelOne Enterprise include?

Singularity Enterprise (custom pricing, contact sales) adds Agentic AI SOC Analyst and Full Visibility and Forensics capabilities to all Commercial features, plus expert-led onboarding and training.

Source
Semperis: Does it require agents on domain controllers?

It collects directory changes from the AD replication stream, which is what lets it see changes that bypass the security log. Deployment details vary by product and version, so confirm the exact architecture against your domain controller change-control rules.
