deep packet inspection

Deep Packet Inspection Appliance

The Deep Packet Inspection Appliance DPIA is a powerful network appliance that enables the interception and real-time monitoring of internet applications, protocols, traffic data and meta-data. Although primarily a law-enforcement and intelligence gathering system, it can also be successfully deployed as an effective data retention or content filtering platform that is capable of deep packet inspection over fixed line and mobile networks.

The DPIA can correlate the flow of traffic between different protocol layers, for example, SIP-RTP, RADIUS-IP, GTP-C and GTP-U sessions, and is not limited to capturing data on the packet level. Unlike most deep packet inspection products, the DPIA is able to extract protocol data and appplication meta-data from over 1000 protocols – in real-time.

The DPIA leverages bleeding edge technologies and proprietary know-how to decode application sessions, decapsulate tunneling protocols, detect encrypted protocols and reassemble TCP/IP flows. As a result, it can extract relevant data such as e-identities, timestamps, network addresses and application identifiers, phone numbers, URLs as well as selected content. The end-result being a much deeper inspection of real-time network data.

The DPIA can be fully integrated into law enforcement interception management systems, captured data can be processed in real-time and immediately secured and mediated before delivery to an authorized law-enforcement or intelligence agency. The hand-over interfaces are fully compliant with both ETSI and 3GPP standards which makes the DPIA a cost-effective, flexible turn-key solution.
