EXPERT RESPONSE
Vendors now shipping third-party IPsec VPN clients for Pocket PCs include Maya Software and V-ONE. As operating systems have matured, IPsec has been embedded into TCP/IP stacks – for example, embedded IPsec clients are now included with new Symbian OS and Windows Mobile 2003 PDAs.
Embedded IPsec could reduce demand for third-party VPN clients. In the Win32 market, third-party IPsec clients have persisted because they are easier to use and provide value-added features when paired with remote access concentrators – your Win32 Cisco VPN client is a good example. Only time will tell if the same trend will hold for PDA IPsec clients, but here's one example: Bluefire announced that it will add a VPN client to its centrally-administered Pocket PC security suite by the end of this year.
