DataNext Systems Pvt. Ltd. is a DIPP recognized startup in cloud security, located in Bangalore, India, working on enterprize grade security product (basically a security framework), through inhouse R&D.
The product "DNXSYS® Cloud Security" is essentially a cloud based Security Gateway (CSG), which has:
1) a software module running on servers based in the cloud (remote Data Centres), forming a software based gateway to analyse all the network traffic at L2, L3 and L4 layers and takes security related decision based on the policies set and live traffic analysis. It also generates logs and then reroute the data frame to its intended destination. We call it DNXSYS™ CSG. The destination and the source machines communicate normally and typically CGS processes are hidden from them.
2A) and a hardware component (DNXSYS™ edge router appliance), which are installed on premises at customer sites, as an edge routing device. It is this edge routing component, which make possible to propel (routes) L2 data frames into one of the many instances of CSG. The hardware component synchronises continuously with a master CSG and knows exactly where to send data traffic into the cloud. Due to the capability to send L2 data frames, the source and in cloud destination machine could interact over a single LAN, as well as all data traffic are scanned and a monitoring could be done (at CSG) based on user IDs (through their login machine MAC as well as local IP address), and helps organisations form enforce security policies well.
2B) For some cloud based machines, DNXSYS™ CSG secures them in reverse proxy mode and also scanning L3, L4 network traffic data.
