Where each one falls short

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

Silent Eight

  • Automated disposition has to clear model risk governance and a regulator, and the shadow running period before auto-close is permitted can consume most of the first year of the contract.
  • It does not improve detection, so an institution with a poorly tuned monitoring system automates the handling of bad alerts rather than fixing why they exist.
  • Pricing is tied to alert volume, which means efficiency gains elsewhere that reduce alerts also reduce the vendor bill in a way sales teams structure minimums against.
  • The headcount saving is only realised if the institution actually reduces the analyst pool, and many banks redeploy rather than cut, leaving the business case unrealised on paper.
  • As a mid-sized private vendor serving tier one banks, concentration risk cuts both ways; the loss of one large client materially affects the company, and buyers should ask about financial stability during diligence.

Splunk Enterprise Security

  • Splunk Enterprise Security is licensed separately from the Splunk platform, so a SIEM deployment needs both
  • Splunk publishes no rate for Enterprise Security and directs buyers to contact a pricing expert
  • UEBA, SOAR and automated threat analysis require the Premier edition rather than Essentials
  • The platform underneath can be billed by ingest volume, workload or activity, so the total cost depends on a pricing model chosen at contract time rather than a list price
