|
|
|---------|---------|---------|
|
|
| shodan | >=1.28 | Shodan API for host discovery |
|
|
| requests | >=2.28 | HTTP API calls |
|
|
|
|
## CLI Usage
|
|
|
|
```bash
|
|
python agent.py --domain example.com --org "Example Corp" --shodan-key <key> \

|
|
Searches Shodan for hosts belonging to a named organization.
|
|
|
|
### `check_email_security(domain)`
|

Checks for SPF and DMARC DNS records to assess email security posture.
|
|
|
|
### `check_web_technologies(domain)`
|
|
