Enterprise Security Connector is a VM that you deploy in your enterprise to act as a DNS forwarder, DNS sinkhole, or an HTTP Forwarder.

1. Secure DNS Forwarder. An internal DNS resolver that forwards traffic to SIA where SIA policy is applied. DNS Forwarder allows you to identify machines that are making requests. By default, the DNS forwarder is enabled in Security Connector version 2.6.8 or later. 

2. DNS sinkhole. Receives suspicious or malicious traffic. As a DNS sinkhole, Security Connector identifies machines that are infected with malware, attempts to download malware, or communicates with C&C servers.

3. HTTP Forwarder. An enterprise proxy that forwards web traffic to SIA Proxy.
