Casebook

INVESTIGATION RECORD LAYER FOR SOC TEAMS

Investigations your team can understand, defend, and reuse.

Casebook builds an evidence-backed case for every alert, shows what is missing, lets your team review and preserve the decision, and makes that investigation available to the next analyst who sees the same pattern.

The pain

Your senior analyst investigates a tricky alert. They figure it out.

Six months later, they leave — and their reasoning goes with them.

15 failed logins on alice from 203.0.113.14 on WIN-DC01 — brute-force pattern

Observed15 failures from 1 IP between 15:00:40 and 18:08:39

DeviationFirst-of-its-kind cluster for this account.

What if this is wrong?

  • This is wrong if 203.0.113.14 is your Red Team scanner.
  • This is wrong if alice was locked out by an automation script.

Every finding in Casebook looks like this. Not a black-box confidence score. A specific claim, with its evidence, its baseline comparison, its human author, and its own falsifying conditions.

That is what makes a finding reviewable. Your team can agree with it, correct it, or rule it out — because they can see exactly what would change its mind.

Less repeated work

Patterns your team has explained don't need to be re-investigated when they recur.

Clearer review and handoff

Every finding shows its evidence, the baseline it deviated from, and the named human who taught the pattern.

Expertise preserved

Investigations your team completes stay available for the next investigation, and for the next analyst who sees the same pattern.

How Casebook works.

Four steps. No new SIEM to learn. Casebook sits beside Splunk, not on top of it.

01

Bring evidence

Connect Splunk or drop a log. Casebook receives what happened, no interpretation.

02

Investigate

Casebook activates what your team has taught it and shows what fits, what's missing, and what needs review.

03

Review

Approve the finding, adjust it, or teach Casebook a new pattern.

04

Preserve

Every Case File stays sealed and available for the next investigation.

See one complete investigation.

A synthetic case, start to finish: the evidence, the finding, what stayed unexplained, and the decision the team preserved. No signup, and none of your data.
