# Abnormal Security

Integrating **Abnormal Security** with **ThreatDefence** allows you to ingest advanced email security telemetry—including phishing detections, business email compromise (BEC) alerts, and behavioral anomaly signals—directly into ThreatDefence. This ensures that identity and email-based threats are correlated with other security data for end-to-end monitoring and incident response.

***

## Step 1. Obtain API Credentials and Configure IP Safelist

1. Sign in to the **Abnormal Portal**.
2. Navigate to **Settings → Integrations**.
3. Locate the **Abnormal REST API integration** and click **+ Connect**.
4. Copy and save the **Access Token** securely (e.g., in a password vault). You will provide this to ThreatDefence later.
5. In the **IP Safelist** field, add the ThreatDefence SOC collector IP address ranges.

> **Note:** Your ThreatDefence representative will provide the correct IP addresses to safelist.

***

## Step 2. Provide Credentials to ThreatDefence

Send the following details to your ThreatDefence representative at [**support@threatdefence.com**](mailto:support@threatdefence.com):

* **Access Token** (from Step 1)
* **Host** — based on your region:
  * **US:** `api.abnormalplatform.com`
  * **EU:** `eu.rest.abnormalsecurity.com`
* **Credential Expiry** — (optional) if your token has an expiration date.

ThreatDefence will configure ingestion so Abnormal Security event data is collected and correlated within the ThreatDefence SecOps platform.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.threatdefence.com/siem-integrations/email-security/abnormal.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
