Where each one falls short

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

Bonfire

  • It is a sourcing and evaluation tool rather than full procure to pay, so requisitions, purchase orders and invoicing stay in the finance system and the join between them is the agency's problem.
  • Since the acquisition path from GTY to GI Partners to Euna Solutions, Bonfire sits in a portfolio alongside products it once competed with, which narrows a shortlist that appears independent.
  • Suppliers must register on the portal to bid, and small local vendors reliably complain about the extra account, which can reduce responses on low value solicitations.
  • Pricing is quoted rather than published and scales with solicitation volume, so an agency with a few very large procurements pays a model designed around throughput.
  • Contract management after award is thin compared with dedicated contract lifecycle products, so agencies often buy a second system for the obligations the award created.

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
