Where each one falls short

CodeSandbox

  • Detailed paid plan pricing was not published on the accessible pages, making cost comparison difficult.

  • Public sandboxes are visible to others by default, which is not ideal for proprietary code.

Nessus

  • Nessus Professional is $4,790 for one year, with no free or low cost commercial tier
  • Multi year terms are the only discount route, at $9,330.95 for two years and $13,637.54 for three
  • It is a single user scanner, so team workflows mean migrating to another Tenable product
  • Tenable One vulnerability management is priced separately, starting at $3,500 a year for 100 assets
