DCFDâ„¢ 3500 Meets Demand for IP Based Surveillance:

Lawfully authorized electronic surveillance (LAES - sometimes referred to as "wiretapping" or "lawful intercept") is a critically important law enforcement tool that police and other authorized government agencies use to investigate and prosecute criminals. LAES is the collection of (1) the contents of communications; and/or (2) communication identifying information. With the rapid growth of IP based networks (such as the Internet), criminals and terrorists have started using IP based applications for communications (email, chat, instant messaging, voice over IP, FTP etc) instead of voice. A clear need has emerged to create products and standards that can enable surveillance of IP based communications. Top Layer's richly constructed DCFD 3500 product line plays an important role in providing these services 

The DCFD 3500 can extract data flowing over the network based on an IP address, MAC address, email address, login user names, Instant Messenger handle, specific  protocol, or application. Importantly, the device is designed to capture only the traffic to or from the entity listed on the warrant issued by the appropriate law enforcement agency. In so doing, the Top Layer solution preserves the privacy of all non-warrant defined IP traffic.
