Where each one falls short

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

Everlaw

  • Quote-only pricing, and ediscovery is typically billed on data volume, which makes costs hard to predict in advance
  • Specialist product: outside litigation and investigations there is no use for it
  • Predictive coding requires a properly trained review workflow, and poor input produces unreliable prioritisation
  • Data volume charges can escalate sharply on large matters

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
