Key differences explained

Certified assessor review

Constant includes certified assessor review after AI pre-review. Vanta publishes an Australian auditor network and auditor portal. A network gives customers a path to an auditor, but is not the same claim as assessor review included in the product price.

Evidence automation

Vanta publishes hourly automated tests and a broad integration ecosystem. Constant publishes connected evidence collection and manual uploads, with the evidence moving through AI pre-review and certified assessor review.

Australian operation

Vanta is a US company with a Sydney office, APAC support, and an Australian AWS data-centre option. Constant is designed, owned, and operated in Australia, with Australian data residency, support, and assessor review.

Product philosophy

Constant focuses on Australian framework guidance and reviewed assurance. Vanta focuses on broad global compliance automation, continuous testing, trust reporting, and enterprise integrations.

Which approach may fit?

Neither approach is presented as universally better. They are designed around different priorities.

Constant may suit organisations looking for

  • Australian Essential Eight assurance with assessor review included
  • Australian ownership and onshore operation
  • Clear control guidance for the team doing the work
  • A public pricing path and included assessor costs

Vanta may suit organisations looking for

  • Broad global compliance automation
  • Hourly automated tests and a large integration ecosystem
  • Trust management and customer-facing assurance
  • Multi-framework enterprise programs with APAC support
