The short version

  • Only Spacelift has a free tier, so it costs nothing to try first.
  • Each has a real cost: Microsoft Defender for Endpoint pricing not published on public websites; quote required from Microsoft sales; Spacelift users are unlimited and private workers are metered, so deployment concurrency rather than headcount drives the bill, which inverts how most engineering budgets are built and is easy to under-forecast.
  • They diverge on capability: Microsoft Defender for Endpoint covers Threat & vulnerability management, Spacelift covers Multi-tool orchestration.
  • 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.

Microsoft Defender for Endpoint

  • Pricing not published on public websites; quote required from Microsoft sales
  • Defender for Endpoint Plan 1 and Plan 2 do not include server licenses; additional licensing required for server protection
  • Specific feature differences between Plan 1 and Plan 2 require consulting Microsoft documentation

Spacelift

  • Users are unlimited and private workers are metered, so deployment concurrency rather than headcount drives the bill, which inverts how most engineering budgets are built and is easy to under-forecast.
  • There is no affordable paid entry point. The free tier stops at two users and the next tier is a five-figure commitment with nothing in between.
  • Three of the five tiers are quote-only, so a shortlist cannot be costed without entering a sales process with each vendor on it.
  • The self-hosted build lags the hosted one, has no public worker pool and lacks the Azure and Google Cloud integrations available in the SaaS product, with OIDC federation offered as the workaround.
  • Stacks, Rego policies, Blueprints, Spaces and Spacelift-managed state are proprietary constructs, so leaving means rebuilding the orchestration layer rather than pointing it at a different runner.

Answered from the vendors’ own pages

Microsoft Defender for Endpoint: How is Microsoft Defender for Endpoint priced?

Defender for Endpoint is bundled into Microsoft 365 enterprise subscriptions. Plan 1 is included in Microsoft 365 E3, and Plan 2 is included in Microsoft 365 E5. Individual pricing is not published separately.

Source
Spacelift: How is Spacelift priced?

By tier and by private worker count rather than per user. Users are unlimited on every paid plan. The published figure on the pricing page carries no period label, and the FAQ describes the tier as an annual subscription, so confirm the period in writing.

Microsoft Defender for Endpoint: Does Microsoft Defender for Endpoint offer a trial?

Yes. A free trial is available for prospective customers to test the product before committing to a subscription.

Source
Spacelift: Does it support OpenTofu?

Yes, and Spacelift sponsors the OpenTofu project, which is a substantive hedge for anyone avoiding Terraform under the Business Source Licence.

Microsoft Defender for Endpoint: What is the difference between Plan 1 and Plan 2?

Plan 1 (in E3) includes unified security tools, device controls, network protection, firewall, web/URL controls, APIs, SIEM connectors, and app controls. Plan 2 (in E5) adds endpoint detection and response, deception techniques, automatic attack disruption, exposure management, and threat intelligence.

Source
Spacelift: Is there a self-hosted version?

Yes, described as carrying Enterprise functionality, but it is priced on request and lags the hosted product on cloud integrations.

Spacelift: Why not just use the CI system we already have?

That is the real comparison. General purpose CI handles state, drift, approval gates and concurrency control for infrastructure poorly, and whether that is worth a five-figure floor depends on how much infrastructure change your organisation actually ships.

Spacelift: What happens to our pipelines if we leave?

They do not port. Rego policies, Blueprints, Spaces and managed state are Spacelift constructs and the orchestration has to be rebuilt elsewhere.
