The short version

  • Only Syft has a free tier, so it costs nothing to try first.
  • 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.; Syft lockfile parsing can drop packages silently. An open issue filed in August 2026 reports the yarn v1 cataloguer returning 118 of 745 packages with no error raised, which means a complete bill of materials and an 84 percent incomplete one look identical to the caller.
  • They diverge on capability: Semperis covers Active Directory Forest Recovery, Syft covers Multi-format output.
  • Prices and features above were last checked on 31 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.

Syft

  • Lockfile parsing can drop packages silently. An open issue filed in August 2026 reports the yarn v1 cataloguer returning 118 of 745 packages with no error raised, which means a complete bill of materials and an 84 percent incomplete one look identical to the caller.
  • Fidelity varies sharply by ecosystem. Conan for C and C++, Haskell and Terraform get cataloguer support with no licence data, no dependency relationships and no file ownership, so a C and C++ shop gets the least from it.
  • Binary classification yields no licence or dependency metadata, and vendored or statically linked code is exactly where supply chain risk hides, so the blind spot and the risk overlap.
  • Incorrect CPE values and CPE collisions are recorded as open issues, and since Grype matches on CPE and PURL, an inventory error becomes a false negative in the security report downstream.
  • An inventory is not a risk assessment. Even a perfect bill of materials says a vulnerable version is present, never that the vulnerable function is called, and the triage burden lands entirely on the reader.

Questions people ask

Is Semperis or Syft better?
Neither clearly leads. Semperis starts at On request and Syft at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Semperis or Syft?
Syft has a free tier; the other does not. Paid plans start at On request for Semperis and Free for Syft.
Does Semperis or Syft run on more platforms?
Semperis runs on Web. Syft runs on macOS, Linux, Windows, Docker.
Can I use Syft for free?
Yes. Syft has a free tier, so you can try it without paying. Semperis starts at On request.
What is Semperis best used for?
Semperis is most often used for an organisation that cannot answer an auditor or insurer asking how long it would take to rebuild active directory after a destructive attack, post-incident recovery where domain controllers are compromised and restoring from system-state backup would reintroduce the attacker's foothold, continuous detection of privileged group changes and directory-level tampering that domain controller security logs miss, hybrid estates where ad, entra id and okta all matter and no single tool currently shows changes across the three. Of those, an organisation that cannot answer an auditor or insurer asking how long it would take to rebuild active directory after a destructive attack and post-incident recovery where domain controllers are compromised and restoring from system-state backup would reintroduce the attacker's foothold are not what Syft is typically brought in for.
What can Semperis do that Syft cannot?
Semperis covers Active Directory Forest Recovery, Malware-free restore, Replication-stream monitoring, Automated rollback. Syft covers Multi-format output, Broad ecosystem coverage, Binary classifiers, In-toto attestations.

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.

Syft: Does Syft find vulnerabilities?

No. It produces an inventory. Grype, from the same company, matches that inventory against vulnerability feeds. They are separate tools and the distinction is frequently lost.

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.

Syft: Does anything in the Anchore stack do reachability analysis?

No. Neither Syft, Grype nor the commercial Anchore platform performs call graph or reachability analysis, so none of them tells you whether a vulnerable code path is actually invoked.

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.

Syft: Is it a CNCF or OpenSSF project?

No. It is single-vendor open source owned by Anchore, with no foundation governance. That is a different licence risk profile from Sigstore.

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.

Syft: What does Anchore Enterprise cost?

Not published. The pricing page is contact-sales only, with named but unpriced commercial and federal tiers.

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.

Syft: How do I know my SBOM is complete?

You largely cannot, which is the honest answer. Silent partial parsing is a known open defect, so a bill of materials used for compliance should be spot-checked against a known dependency list.
