Instead, LDAP queries are wrapped within a series of SOAP messages, which are sent to the ADWS server using NET TCP Binding communication channel. Following, ADWS server unwraps the LDAP queries and forwards them to the LDAP server running on the same Domain Controller. As a result, LDAP traffic is not sent via the wire and therefore is not easily detected by common monitoring tools.

Key management and administration is based on profiles assigned to defined users. Administrators can login using two-factor authentication with Authy or Google Authenticator. From there they can manage their public SSH keys or connect to their systems through a web-shell. Commands can be shared across shells to make patching easier and eliminate redundant command execution.

Bastillion layers TLS/SSL on top of SSH and acts as a bastion host for administration
