DrayTek was one of the first manufacturers to bring VPN technology to low cost routers, helping with the emergence of viable teleworking. In 2004, DrayTek released the first of their VoIP (Voice-Over-IP) products which has become one of their key areas. In 2006, new products aimed at enterprises debuted, including larger scale firewalls and Unified Threat Management (UTM) firewalls products however the UTM Firewalls received little interest amid a saturated market. The UTM products have subsequently stopped being developed and advertised on the DrayTek websites.
DrayTek's Vigor line offers business and consumer DSL-Ethernet modems with support for the PPPoA standard compared to the more the widely supported PPPoE for use with full-featured home routers and home computers without more expensive ATM hardware. PPPoA is used primarily in the UK. Most Vigors also allow a virtual private network (VPN) connection directly to the router, without the need to pass the VPN packets through to a VPN server running on a computer. With appropriate configuration it is possible to make a VPN connection remotely to a Vigor router, use Wake on LAN to start up a computer connected to it, and make a remote administration connection to control the computer.
