The short version

  • Only HashiCorp Boundary has a free tier, so it costs nothing to try first.
  • Each has a real cost: HashiCorp Boundary hashiCorp was acquired by IBM in February 2025 and Enterprise licensing now runs through IBM Passport Advantage; IBM has already retired HCP Vault Secrets, so Boundary's roadmap depends on IBM portfolio decisions rather than HashiCorp's own product strategy.; SentinelOne Singularity deployment and configuration requires professional services ($5,000 to $25,000)
  • They diverge on capability: HashiCorp Boundary covers Identity-based access, SentinelOne Singularity covers Behavioral AI.
  • 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.

HashiCorp Boundary

  • HashiCorp was acquired by IBM in February 2025 and Enterprise licensing now runs through IBM Passport Advantage; IBM has already retired HCP Vault Secrets, so Boundary's roadmap depends on IBM portfolio decisions rather than HashiCorp's own product strategy.
  • Enterprise pricing is not published anywhere, and the features most organisations actually need for compliance, notably session recording, are Enterprise only, so the free community edition is rarely the version you end up buying.
  • It solves access to infrastructure, not to applications; browser-based internal tools, SaaS admin consoles and APIs need a separate control, so Boundary is one component of a zero-trust programme rather than the whole thing.
  • Running it yourself means operating controllers, worker nodes and a Postgres database in a highly available configuration, and if that control plane is down nobody can reach production, which makes it a new critical dependency.
  • It is materially easier to adopt if you already run Vault and Terraform; teams without that ecosystem face a steeper learning curve than a device-based mesh product like Tailscale, for a similar access outcome.

SentinelOne Singularity

  • Deployment and configuration requires professional services ($5,000 to $25,000)
  • Optional modules like Ranger and Vigilance add to total cost of ownership
  • Complex pricing tiers make budgeting difficult for large deployments

Answered from the vendors’ own pages

HashiCorp Boundary: Is Boundary open source?

The community edition is, under MPL 2.0. Boundary Enterprise is commercial and is now sold through IBM Passport Advantage.

SentinelOne Singularity: What does SentinelOne Singularity XDR cover?

Singularity XDR unifies detection and response across endpoints, cloud, identity, network, and mobile, providing centralized visibility and automated response across all attack surfaces.

Source
HashiCorp Boundary: Does it replace a VPN?

For infrastructure access, largely yes. It grants a session to a specific target rather than putting the user on a network, but it does not cover browser-based internal applications.

SentinelOne Singularity: How does SentinelOne correlate data across security tools?

Singularity normalizes data from endpoints, identity, cloud, and third-party security tools into a unified data layer, enabling automatic correlation of signals without manual integration.

Source
HashiCorp Boundary: What does Boundary Enterprise cost?

HashiCorp does not publish Boundary pricing. It is quoted, and since the IBM acquisition it is transacted on IBM licensing paper.

SentinelOne Singularity: Can SentinelOne integrate with existing security tools?

Yes, Singularity Marketplace provides pre-built, one-click integrations with email, network, firewall, and SaaS security tools, avoiding vendor lock-in while extending detection capabilities.

Source
HashiCorp Boundary: Do I need Vault to use it?

No, but the just-in-time credential brokering that makes Boundary worthwhile depends on Vault or an equivalent secrets store.

SentinelOne Singularity: What is the pricing model for SentinelOne Singularity?

SentinelOne pricing ranges from $5.83 to $17.50 per endpoint per month across five tiers, with optional add-on modules and enterprise pricing available on request.
