Our cloud is running in a google app engine, with https, fullrest APIs and Oauth, and other security standards.
The Wireless Security for the Smartee can be: Open, WEP, WPA, WPA2, WPA/WPA2-Enterprise.
The Smartee has also features for Port Forwarding, Port Filtering, Firewall
Mobile apps use fullrest with https and OAuth with the cloud, and dlna/upnp when run in the same wifi router.
For M2M we suggest using Zigbee or ZWave devices; Zigbee built in Smartee support AES 128 hardware encryption engine with true random number generator; for standard Smartee we implement Zigbee Home Automation profile (Zigbee standard) and smart energy profile, but we can put other standards to Zigbee, depending on the client.
For Zigbee implementations we use Mesh networks (no ip addresses), that allows each device talk to one other without the Smartee. The communication between each zigbee device is with AES 128, 16 bit and 64 bit addresses (mac).
