Presenter - Mr. Casper Chang-kan, CEO Decision Group Inc. Taiwan

Casper Chang-kan established Decision Computer in 1986 (later to become Decision Group Inc.). At the early stage of Decision, it produced PC board, components and OEM assembling. Owing to the production technology became more mature with stable working capitals, Decision stepped into 286 motherboard production. At that time, there were only 5 manufacturers of 286 motherboard in Taiwan. After 1 year selling & producing, Decision understood that the market will eventually become low profit with high competition. Therefore, Decision decided to produce PC-Based Multi-port RS232/422/485 Serial Cards, Data Acquisition and Measurement Products and Industrial Automation & Control, those are with higher profits by specific technology know-how. Decision developed its own driver & software program to distinguish other competitors, in order to get higher market share and profit.

Since 1993, Decision co-founded with long-term cooperation foreign distributors to incorporate a holding multi-national company: “Decision-Computer International Co., Ltd”. Decision officially stepped into transnational company management. OEM and serial cards have been gradually replaced by advanced & matured PC, and threatened by the growing PC industry neighbors.

At this point, Decision decided to turn into the development & research of cyber forensics, digital property reservation, and successfully developed the series of network packet forensics products:

E-Detective Series of Products:

  • E-Detective System
  • LAN/Ethernet Legal Interception System,
  • Wireless-Detective System-WLAN Legal Interception System,
  • HTTPS/SSL Network Packet Forensics Device,
  • WatchGuard.WLAN,
  • VOIP-Detective and others

Decision has become a leading network forensics software provider in the world, and works with Taiwan Police Agency, Crime Investigation Agency to devote Decision’s digital forensics technology in social security and cybercrime investigation.
