The short version

  • Each has a real cost: 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.; 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.
  • They diverge on capability: One Identity covers Identity Manager, Semperis covers Active Directory Forest Recovery.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

One Identity

  • A government or defence environment requiring privileged session management on a hardened physical appliance rather than a cloud servicenot Semperis
  • A manufacturer with SAP and Active Directory needing provisioning governed under one certification processnot Semperis
  • An enterprise consolidating Active Directory after an acquisition and needing automated account lifecycle across both forestsnot Semperis

Semperis

  • An organisation that cannot answer an auditor or insurer asking how long it would take to rebuild Active Directory after a destructive attacknot One Identity
  • Post-incident recovery where domain controllers are compromised and restoring from system-state backup would reintroduce the attacker's footholdnot One Identity
  • Continuous detection of privileged group changes and directory-level tampering that domain controller security logs missnot One Identity
  • Hybrid estates where AD, Entra ID and Okta all matter and no single tool currently shows changes across the threenot One Identity

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.

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.

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.

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.

One Identity: Does it include privileged access?

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

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.

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.

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.

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.

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.
