What it does

Focuses only on the dangerous tail of patch drift: endpoints still exposed to a critical CVE after their remediation SLA has elapsed. It pages the on-call engineer and records the SLA breach for audit.

When to use it

Use this when low-severity drift is handled by daily tickets but critical exposure needs to interrupt someone now. It is the escalation layer above your routine sweep.

How it works

  1. 1An hourly schedule triggers the check.
  2. 2The flow queries Postgres for devices flagged against a critical-severity CVE.
  3. 3A branch keeps only devices whose patch SLA deadline has already passed.
  4. 4For each breaching device it triggers a PagerDuty incident with the CVE id, hostname, and hours overdue.
  5. 5It writes a breach record back to a Postgres audit table so the SLA miss is provable later.
  6. 6The incident acknowledgement link is returned as the output for the on-call to act on.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect PostgresAny Postgres URL — query, write, migrate.
  2. 2
    Connect PagerDutyIncidents, on-call, escalations.
  3. 3
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  4. 4
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  5. 5
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
