CLion vs Semperis
Semperis
Cybersecurity
Identity threat detection and Active Directory forest recovery for AD, Entra ID and Okta, from a privately held US vendor.
- From
- On request
- Free plan
- No
The short version
- Only CLion has a free tier, so it costs nothing to try first.
- Each has a real cost: CLion specific subscription pricing not listed on product page; 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.
Where they differ

What people use each for
The jobs each tool is most often brought in to do.

- Embedded systems and ARM toolchain developmentnot Semperis
- Remote development via Docker and WSLnot Semperis

- Cross-platform development for Linux and Windowsnot 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 CLion
- Post-incident recovery where domain controllers are compromised and restoring from system-state backup would reintroduce the attacker's footholdnot CLion
- Continuous detection of privileged group changes and directory-level tampering that domain controller security logs missnot CLion
- Hybrid estates where AD, Entra ID and Okta all matter and no single tool currently shows changes across the threenot CLion
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
CLion
- Specific subscription pricing not listed on product page
- Requires reference to separate store page for tier details
- AI credits needed for integrated AI features
- No mention of free trial for commercial 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.

Questions people ask
- Is CLion or Semperis better?
- Neither clearly leads. CLion starts at Free and Semperis at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, CLion or Semperis?
- CLion has a free tier; the other does not. Paid plans start at Free for CLion and On request for Semperis.
- Does CLion or Semperis run on more platforms?
- Both run on Web, so platform support will not decide this one for you.
- Can I use CLion for free?
- Yes. CLion has a free tier, so you can try it without paying. Semperis starts at On request.
- What is CLion best used for?
- CLion is most often used for c and c++ development with real-time analysis, embedded systems and arm toolchain development, remote development via docker and wsl, educational programming instruction. Of those, c and c++ development with real-time analysis and embedded systems and arm toolchain development are not what Semperis is typically brought in for.
- What can CLion do that Semperis cannot?
- Semperis covers Active Directory Forest Recovery, Malware-free restore, Replication-stream monitoring, Automated rollback.
Answered from the vendors’ own pages
CLion: Is CLion free?
CLion offers free licenses for students, teachers, and non-commercial use. Commercial users can purchase subscriptions with organization pricing available.
SourceSemperis: 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.
CLion: What free options does CLion provide?
CLion provides non-commercial use licenses for open-source and hobby projects, plus full licenses for students and teachers without cost.
SourceSemperis: 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.
CLion: Does CLion include AI assistance?
Yes, CLion natively integrates AI with support for Claude, GPT, Gemini, and Grok models. Users can apply JetBrains AI credits or bring their own API keys to avoid vendor lock-in.
SourceSemperis: 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.
CLion: Are there discounts for switching to CLion?
CLion offers a competitive discount of 25% for users switching from other IDEs and similar products.
SourceSemperis: 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.
