Alerts
The Alerts feature provides real-time alerts about critical security events detected by the platform, including data breaches, malware infections, and other potential threats. These alerts enable users to take swift action and mitigate risks effectively.
Key Benefits
- Timely Alerts: Stay informed instantly with alerts sent as soon as a security event is detected—no need to check the platform manually.
- Customizable Criteria: Set up alert rules based on event type and risk level.
- Multiple Delivery Channels: Receive alerts via email, Slack, Microsoft Teams, and Generic Webhook.
How It Works
Asset Monitoring
Users add assets (such as domains, emails, phones, IPs or DWM rules) to the platform.
Event Generation
The platform continuously monitors for security threats. If a detected security event involves one of the user's assets, the platform generates an event.
Alert Delivery
If the user has configured alert rules, the platform sends alerts based on the generated event. Alerts are sent via email, Slack, Microsoft Teams, or Generic Webhook, depending on the user's configured preferences.

You should start receiving alerts from NordStellar in your selected Microsoft Teams chat or channel shortly.
Setting Up Generic Webhook Alerts
Prerequisites
To integrate Generic Webhook alerts, you need an endpoint URL ready where you want to receive the alerts. This endpoint could be part of your own application or a third-party service capable of receiving webhooks.
Note: If your endpoint requires specific authentication or other custom headers (e.g., an API key), ensure you have the necessary Header Name(s) and Value(s) available.
Steps to Configure Generic Webhook Alerts
- Create Your Webhook Endpoint:
- Ensure you have set up an endpoint URL capable of receiving POST requests with JSON payloads.
- Note Your Endpoint URL:
- Copy the URL of your created endpoint.
- Configure the Rule on the NordStellar Platform:
- Navigate to the Alerts section within NordStellar and choose to create a new rule for Generic Webhook.
- Rule Name: Assign a descriptive identifier for the rule (e.g., "Alerts to Custom App").
- Webhook URL: Paste your copied webhook endpoint URL into the designated field.
- (Optional) Custom Headers: If required by your endpoint, click "Add Header" and enter the
Header NameandHeader Value(e.g.,AuthorizationandBearer YOUR_API_KEY). You can add multiple headers if needed.
- Select Event type/s: Choose the category of events you want to be alerted about (e.g., Data Breaches, Malware Infections, Vulnerabilities).
- Risk Level: Set the minimum risk level that should trigger an alert (Informational, Low, Medium, High, Critical).
- Save Your Settings:
- Click “Save” to finalize the configuration.
You should start receiving alerts from NordStellar at your specified webhook endpoint shortly.
Payload Structure
When an alert event matching your rule criteria occurs, NordStellar will send an HTTP POST request containing a JSON payload to your configured Webhook URL.
The exact structure of the JSON payload depends on the Event Type that triggered the alert. The format follows the same specifications as the NordStellar Integrations API.
For detailed schemas and examples for each event type's payload, please refer to the official NordStellar Integrations API Reference:
NordStellar Integrations API Reference→Understanding the payload structure for the specific event types you are monitoring is crucial for correctly processing the incoming alerts in your application or service.
