Klaxon turns "we think something happened" into "we ran the playbook, met every reporting deadline, and sent the right letters to the right regulators." It computes your 50-state + HIPAA / GDPR / DFARS / SEC / CIRCIA obligation clocks from the incident timeline, cascades reminders before you miss them, and seals the timeline so it holds up after the fact — at SMB price, local-first.
Toggle states (assume 600+ residents each, PHI involved). The engine computes who you must notify and by when — deterministically, from law, no guessing.

The append-only timeline on the left, the live legal deadline clocks on the right — the actual Klaxon war-room. Open the console →
50 states + DC/PR and HIPAA, GDPR, DFARS, PIPEDA, Québec, SEC, and CIRCIA — each on a live countdown from the legally-correct trigger, with current law (CA SB 446, OK SB 626) encoded and proposed rules (CIRCIA, HIPAA 72h) clearly labeled proposed.
T-48 / 24 / 4h / overdue stages computed locally from the timeline, with business-day and federal-holiday-aware deadline math. Opt in to push a secret-free reminder to email / Slack / Teams when the browser is closed.
An append-only forensic timeline sealed with a SHA-256 hash chain — any edit to a past event shows as TAMPERED — plus roles, tasks, and chain-of-custody evidence hashes. The defensibility artifact auditors and carriers ask for.
Nine jurisdiction-correct templates that prefill from the incident and flag missing statutory fields. The legal scaffolding is engine-computed; only the narrative is yours. Plus the playbook library and a scored tabletop runner.

"The deadline clock is the thing. We knew we had a breach; we didn't know we owed three AGs and HHS by different dates. Klaxon laid it all out in a minute."
"We run tabletops for a book of 20 clients. Bulk scheduling plus a scored AAR we can white-label is exactly what the consultants charge $15k a pop for."
"Local-first sealed it. A live incident is the last thing we want sitting in someone else's cloud. The letters generate on-device."
