How It Works

Ranked by what actually needs attention first.

VIGIL doesn't produce a generic risk score — it classifies against the real taxonomy HMRC uses and orders the output most-critical first.

01

Read the client profile

Filing history, sector, and structure are read against the patterns that typically precede each of the 14 notice types.

Profile read
02

Classify against the taxonomy

Each likely risk is classified by notice type and urgency, with a duplicate check against risks already flagged.

Taxonomy classification
03

Attach the response window and exposure

Every flagged risk carries an estimated response window in days and an estimated financial exposure, ordered most-critical first.
