The short version

  • Only Socket 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.; Socket team plan requires minimum 5-developer commitment, expensive for small teams
  • They diverge on capability: Semperis covers Active Directory Forest Recovery, Socket covers Malware 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.

Socket

  • Team plan requires minimum 5-developer commitment, expensive for small teams
  • Business plan $50/dev/month becomes costly for teams exceeding 20 members
  • Enterprise pricing requires custom consultation with no transparent pricing
  • Free plan limited to individual developers without team collaboration
  • Reachability analysis improvement (90% false positive reduction) only on Enterprise

Questions people ask

Is Semperis or Socket better?
Neither clearly leads. Semperis starts at On request and Socket at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Semperis or Socket?
Socket has a free tier; the other does not. Paid plans start at On request for Semperis and Free for Socket.
Does Semperis or Socket run on more platforms?
Semperis runs on Web. Socket runs on Web, CLI, GitHub.
Can I use Socket for free?
Yes. Socket 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 Socket is typically brought in for.
What can Semperis do that Socket cannot?

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.

Socket: How many zero-day attacks does Socket detect?

Socket detects over 100 zero-day attacks weekly across JavaScript, Python, and Go ecosystems.

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.

Socket: What is precomputed reachability analysis?

Socket's precomputed reachability analysis cuts CVE false positives by 60% automatically on Team plans, and up to 90% on Enterprise plans through function-level analysis.

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.

Socket: Is there a discount for annual billing?

Yes. Socket offers a 20% discount for annual commitments across all subscription tiers.

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.

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.
