The short version

  • Each has a real cost: Fortinet FortiGate security services are sold as separate FortiGuard subscription bundles, so ATP, UTP and ENT determine which protections are actually active; 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: Fortinet FortiGate covers Next-generation firewall, Semperis covers Active Directory Forest Recovery.
  • 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.

Fortinet FortiGate

  • Security services are sold as separate FortiGuard subscription bundles, so ATP, UTP and ENT determine which protections are actually active
  • Throughput is tied to the appliance model, from 500 Mbps on the FortiGate 30G to 520 Gbps on the 7121F, so capacity planning is a hardware purchase
  • Pricing is not published and goes through partners

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

Fortinet FortiGate: What are the FortiGate security bundle options?

Fortinet offers three FortiGuard AI-Powered Security Services bundles: ENT Bundle (ultimate security for networks, web, file, SaaS, data, and devices), UTP Bundle (advanced web and network protection), and ATP Bundle (protection against network intrusions and malware with IPS, antivirus, and application control).

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.

Fortinet FortiGate: How do I get pricing for FortiGate?

Pricing is not published on the product page. To obtain a quote, you can request a free product demo or connect with a security expert through the contact options on the site.

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.

Fortinet FortiGate: Is there a free trial for FortiGate?

The product page does not mention a free trial. However, Fortinet offers a free product demo that allows you to evaluate the solution before committing to a purchase.

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.
