docs(connectors): add Group-IB ASM connector setup guide

Document the Group-IB Attack Surface Management connector in the
Pro connectors tool reference and add it to the supported-tools list.

Covers Basic Auth (username = ASM login, password = API key), the fixed
https://asm.group-ib.com location, per-company Record discovery, assets
mapped as endpoints, incremental sync, and the optional company_id
scoping fallback.

+## **Group-IB ASM**
+
+The Group-IB ASM (Attack Surface Management) connector uses the Group-IB ASM REST API to pull external attack-surface **issues** (findings) into DefectDojo. DefectDojo discovers each Group-IB **company/tenant** as a separate Record and imports that company's issues on a scheduled, incremental basis. The asset each issue relates to (a domain, IP, or URL) is attached to the resulting finding as an **Endpoint**.
+
+#### Prerequisites
+
+You will need your Group-IB ASM login and an API key. We recommend creating a dedicated service account for DefectDojo so that automated activity can be distinguished from manual team actions.
+
+To generate an API key:
+
+1. Open Group-IB Attack Surface Management, click **Help** in the lower-left corner, and select **API**.
+2. Click **Generate API Key** (top-right, under your username).
+3. Enter your SSO password and click **Next**, then click **Copy token**.
+4. Store the key in a secret manager and plan for regular rotation.
+
+#### Connector Mappings
+
+Group-IB ASM authenticates with HTTP Basic Auth, where the username is your ASM login and the password is your API key. **Both values are required** — the API key alone is not sufficient.
+
+1. Enter `https://asm.group-ib.com` in the **Location** field. This is the same for all Group-IB ASM tenants.
+2. Enter your ASM login (usually an email address) in the **Username** field.
+3. Enter your API key in the **API Key** (Secret) field.
+4. Optionally, set a **Minimum Severity** to limit which findings are imported. Findings below the selected severity are not imported.
+
+DefectDojo maps each Group-IB **company** as a separate Record, using the company ID as the identifier. On the first Sync, DefectDojo backfills recent issue history; subsequent Syncs are incremental, pulling only issues changed since the last Sync (tracked by each issue's most recent `lastSeen` timestamp).
+
+#### Scoping to a single company (optional)
+
+By default, the connector automatically discovers the companies available to your API credentials (via the ASM `clients` endpoint) and creates one Record per company. This is the recommended setup and requires no extra configuration.
+
+If the `clients` endpoint is not available for your tenant — for example, when it is restricted to partner/MSP accounts — the connector can be scoped to one company by supplying its **company ID** as a `company_id` tool-specific field on the connector configuration. When `company_id` is set, DefectDojo uses that company directly instead of enumerating companies. Leave it unset to use automatic discovery.
+
+See the Group-IB ASM REST API manual (available in-product via **Help → API**) for more information.

 ## **IriusRisk**
 
 The IriusRisk connector uses an API token to pull threat modeling data from your IriusRisk instance.
