# Domain Certificate

The Domain Certificate connector finds a list of subdomains for a domain and finds the certificates for the main domain and each subdomain.

## Why Should You Use the Domain Certificate Connector?

The Domain Certificate connector provides visibility into certificates for your domain and subdomains. You can use this visibility to:

- monitor certificate expiration
- renew certificates before they expire

## How Does This Connector Work?

Lucidum executes read-only requests to the domain to find all subdomains and all certificates. Lucidum does not retrieve any data stored on your assets.

## Configuring the Connector in Lucidum
