Where each one falls short

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

DTiQ

  • You are buying labour, so the cost per site is far higher than a self-service video licence and it does not fall as camera prices do.
  • Audits are sampled, not continuous, so a problem outside the reviewed window is invisible and the score is a statistical impression rather than a complete record.
  • Nothing is published on price and the commercial shape is a multi-year managed service agreement, which is harder to exit than a software subscription and typically involves bundled hardware you do not own.
  • Ownership changed in a $200 million Digital Alpha led investment tied to a Cisco Meraki partnership, so the hardware and network roadmap may shift under an existing estate.
  • It is built around restaurant, convenience and retail operating models, so an organisation outside those verticals gets a generic video product and pays for an audit methodology that does not fit its work.

Tenable Nessus

  • Nessus Professional is $4,790 for one year, sold as an annual licence rather than a per scan or usage based fee
  • Support beyond the base entitlement costs an extra $400 per year for Advanced Support with 24x365 phone and chat access
  • The on demand training course is a separate $275 purchase for a single person for one year
  • Multi year discounts require paying for two or three years up front
