FROM ONE ALERT
TO THE WHOLE CAMPAIGN
Stairwell detects threats your stack misses, maps exactly where they spread, and gives you the evidence to close the case, not just the alert.
Built to catch
missed threats
Stairwell preserves every executable it observes. It detects threats without relying on another tool to flag them first.
Resistant to AI malware
by design.
Stairwell analyzes the files themselves, so new variants can surface even when
signatures and behavioral detections
have never seen them before.
Evidence that
never expires.
Detection is a single moment. Stairwell re-examines your full history as intelligence arrives, so a threat missed yesterday still gets caught tomorrow.
ATTACKERS REHEARSE AGAINST
COMMON DEFENSES UNTIL THEIR MALWARE
GETS THROUGH UNNOTICED.
YOU'RE WINNING ON THE WRONG SCOREBOARD.
The industry optimizes for one thing: how fast you clear false positives.
Lower MTTR, more tickets closed, higher auto-triage rates.
It says nothing about the false negative still sitting in your environment.
INTRODUCING
The first AI investigator built on evidence
Every executable, kept forever, continuously re-examined.
HOW IT WORKS?
Backstory continuously collects and preserves evidence, detects threats, runs full investigations, and directs your existing tools to comprehensively respond . Every new piece of intelligence starts the cycle again across your entire history in a dedicated environment.
Every question your SOC couldn't answer.
Answered.
Autonomous detection
Stairwell continuously analyzes every new executable. Definitive verdicts in seconds, independent of your other tools. Files your stack overlooks still get investigated.
Instant & continuous retro-hunt
Every new piece of intelligence automatically re-scans years of file history. Dormant malware gets caught.
Blast radius mapping
Every copy and every variant (renamed, recompiled, mutated) across all hosts and all time: what arrived, when, where it spread, which machines are affected.
Recommended actions
Backstory closes each investigation with a full campaign report, mapped to MITRE, and concrete actions for your other tools: containment, blocking, cleanup.
