Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Basis Theory

  • The Starter plan is 995 US dollars a month before any volume, which is a real floor for an early stage company and puts the product out of reach of teams tokenising a few thousand records.
  • Starter is limited to the US region, so a company with European data residency requirements is pushed into a quoted Scale or Enterprise agreement immediately.
  • Log retention on Starter is 24 hours, which is well below what most security teams expect for a system holding cardholder data and forces an upgrade for reasons unrelated to volume.
  • Migrating away means moving card data out of the vault, which requires processor and assessor involvement and is slow, so the portability argument that attracts buyers cuts against them at exit.
  • An attestation of compliance covers the vendor environment, not your assessment; your assessor still decides what is in scope, and buyers occasionally discover their integration pattern pulled systems back into scope anyway.

HashiCorp Vault

  • Policies are written in HCL with no graphical user interface for policy management or editing
  • Unsealing requires managing multiple key shares and coordinating a quorum of operators
  • Community Edition lacks enterprise features like namespaces and disaster recovery replication
  • Requires additional monitoring solutions for alerting and observability

Answered from the vendors’ own pages

Basis Theory: Does this make us PCI compliant?

It removes cardholder data from your systems and gives you an AOC plus documented responses for most of a SAQ D. Your assessor still determines your scope, and a careless integration can pull systems back in.

HashiCorp Vault: Does HashiCorp Vault have a free version?

Yes. The open-source Community Edition is completely free and includes core secrets management, dynamic secrets, and encryption as a service. It is self-hosted with no licensing fees or secret count limits, but lacks enterprise features like namespaces, disaster recovery replication, and Sentinel policies.

Source
Basis Theory: What does it cost to start?

995 US dollars a month on Starter, including 20,000 tokens, a production PCI Level 1 environment and US hosting. Higher tiers are quoted.

HashiCorp Vault: Can I use HashiCorp Vault in production?

The Community Edition is suitable for non-production environments and small teams. For production deployments, organizations typically use HCP Vault Dedicated (managed cloud service starting at approximately 22 USD per month) or Vault Enterprise with custom pricing that includes disaster recovery, performance replication, and 24/7 support.

Source
Basis Theory: Can we switch payment processors without re-collecting cards?

Yes, that is the main non-compliance reason to buy it. You hold the tokens and detokenise into whichever processor you route to.

HashiCorp Vault: What are the main integrations available?

Vault integrates with AWS, Azure, Google Cloud, Active Directory, Okta, and 80+ other platforms. It supports dynamic credential generation for cloud providers, database systems, and identity services, enabling centralized secret management across multi-cloud infrastructure.

Source
Basis Theory: Is data stored outside the United States?

Not on Starter, which is US only. Other regions require a Scale or Enterprise agreement.

HashiCorp Vault: Does Vault work offline?

Vault requires network connectivity to function as it is a centralized secrets management server. However, it can be deployed on-premises for air-gapped environments, and clients can cache short-lived tokens for temporary offline access once authenticated.
