The short version

  • Only Harness has a free tier, so it costs nothing to try first.
  • Each has a real cost: Harness essentials and Enterprise pricing requires sales contact; no published rates; 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.
  • Prices and features above were last checked on 30 August 2026.

What people use each for

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

Harness

  • Deploying apps to AWS, Azure, and Google Cloud with rollbacksnot Semperis
  • Integrating security scanners throughout build pipelines before productionnot Semperis
  • Automating cloud cost reduction and tracking unit-level expensesnot Semperis
  • Enabling developers to provision infrastructure without operations bottlenecksnot Semperis
  • Assessing deployment frequency and lead time productivity metricsnot 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 Harness
  • Post-incident recovery where domain controllers are compromised and restoring from system-state backup would reintroduce the attacker's footholdnot Harness
  • Continuous detection of privileged group changes and directory-level tampering that domain controller security logs missnot Harness
  • Hybrid estates where AD, Entra ID and Okta all matter and no single tool currently shows changes across the threenot Harness

Where each one falls short

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

Harness

  • Essentials and Enterprise pricing requires sales contact; no published rates
  • DevOps Essentials has no on-premises deployment option
  • Internal Developer Portal requires minimum 20 developer licenses
  • Pipeline execution history retention 6 months (Essentials) vs 25 months as add-on (Enterprise)

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

Harness: Is there a free Harness plan?

Yes, Harness offers a free plan for individual developers and small teams with open source options including Harness Open Source and Litmus Chaos.

Source
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.

Harness: What are Harness's paid pricing tiers?

Harness offers Essentials for growing teams and Enterprise for large-scale organizations. Both require contacting sales for custom pricing. Pricing is based on modules and features selected.

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.

Harness: Can Harness be deployed on-premises?

Enterprise plans include self-managed platform deployment option. DevOps Essentials bundle does not offer on-premises deployment.

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.

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.
