About the Device
Dynamic Host Configuration Protocol (DHCP) is a client/server protocol that automatically provides an Internet Protocol (IP) host with its IP address and other related configuration information such as the subnet mask and default gateway. DHCP allows hosts to obtain required TCP/IP configuration information from a DHCP server.

To facilitate secure communication and align with our best practice, we strongly encourage the use of Transport Layer Security (TLS) between your security devices and our Adaptive MxDR platform for event forwarding.
While we understand that TLS support may not be available on all devices, if your devices do support TLS communication, we recommend utilizing port 10014 for seamless integration.
In some cases, the upgraded version of the device might incorporate TLS support without prior notice. If you come across such a scenario or for further assistance in configuring TLS, we kindly ask you to reach out to your dedicated Adaptive MxDR Service Delivery Lead.
