Monitor failed logins in Email

Catch the login failures that look like an attack — repeated misses from one address — with geo and network context attached before they reach you.

the event

You emit login.failed with this shape. The TypeScript SDK keeps the call type-safe, and the event is stored whole — so every field below is available to the pipeline by name.

  • emailstring
  • ipstring
  • reasonstringbad-password | locked | mfa
  • attemptnumberconsecutive misses

emit it

From your code with the TypeScript SDK — or any language over the REST endpoint and signed webhook ingress.

emit login.failed
import { ingest } from "@ingestlayer/sdk";

await ingest("login.failed", {
  email:   creds.email,
  ip:      req.ip,
  reason:  result.reason,
  attempt: result.consecutive,
});

route it to Email

Send a transactional email to one or more recipients, addressable from event fields.

  1. 01

    set the recipient

    Enter a fixed address, or reference an event field like $event.payload.email to route per event.

  2. 02

    write subject and body

    Both accept $event.* templates. The body renders as plain text with an optional summary table of the payload.

  3. 03

    confirm the sender

    Mail goes out from mail@notify.ingestlayer.com with SPF and DKIM aligned. Set a reply-to if you want responses to reach you.

notes

questions

How do I avoid alerting on typos?
Filter on the attempt count so a single fat-fingered password stays quiet and only sustained failures escalate.
Where does the geo come from?
enrich.entity resolves the IP to geo, ASN, and a known-bad flag in flight, so the alert carries the context to act on.
Is it safe to post emails to a channel?
redact.pii masks the email for the chat destination while the full record still lands in your audit table.
