Every alert has a

Backstory is Stairwell's agentic investigator. It turns a single alert into a finished case: the full blast radius, the attack written out stage by stage, and specific remediation steps for every asset affected.

Prologue

An investigation usually runs across a sandbox, a threat intel lookup, an EDR search, and a ticket. Backstory runs it in one place, against every file you have collected.

Chapters

The investigation is only half the job. The other half is explaining it. Backstory writes the case stage by stage, in plain language, so the report is done before anyone asks for it.

Epilogue

No case ends in doubt. You know how far the attack reached and what to do about it, on every asset it touched.

Find the plot behind the TTP

The alert names a MITRE technique and stops there. Backstory tells you what that technique did on your machines, which files carried it, and how each one led to the next.

Finish the book

Close the case with actions. What to block, what to isolate, what to remove, and in which tool. Ready to hand to your EDR, your SIEM or your SOAR.
