Triage Aid

A zero-knowledge notebook for triaging security incidents. It sits next to your SIEM or alert queue, keeps triage fast, and encrypts every note in your browser before it is stored.

What it does

Zero-knowledge storage

Notes, customer names and incident IDs are encrypted client-side. The server holds ciphertext and a hash of your login value.

Fast triage editor

A keyboard-driven editor that spots IPs, hashes, domains, UUIDs and CVEs as you type, with double-click to copy.

Seen before

Indicators from earlier triages are flagged when they appear again, with a jump to the earlier note.

IP reputation

Inline lookups with your own API key, bulk lookup with file upload, and an optional browser-extension bridge.

Stats

Verdict trends, the true and false positive split per tenant and type, and a triage-cadence heatmap.

Account security

Optional two-factor login, a one-time recovery key, a quick-unlock passcode and locking across tabs.

How it is built

The principles behind Triage Aid, and the choices that follow from them.

01

Encrypt before it leaves

Notes are encrypted in your browser before they are sent. The server only ever receives ciphertext it cannot read.

02

Two keys from one password

Your password produces two separate values: one unlocks your data, the other logs you in. Even a full copy of the database holds nothing readable.

03

Made for speed under pressure

The editor recognises IPs, hashes, domains and CVEs as you type, and remembers indicators you have seen before, so repeat offenders stand out.

04

Run it where you want

Use it online straight away, or run it on your own server as a single container.
