To date, most solutions have focused on supporting VPN security across only one type of connection. Certicom's MovianVPN product, intended for Palm OS and Windows CE based handhelds, is a good example of this. The focus has been on security. Less attention has been given to usability issues associated with linking mobile workers seamlessly back to corporate networks regardless of connection type. Drescher indicated that most mobile workers will have more than one connection type and that this issue will become increasingly important.
Security is important across all connections.
No one, however, wants to restart applications or reboot each time they move between connection types - wired, wireless or otherwise. Achieving this kind of usability is a complex task. It may be beyond the reach of many small or medium sized IT departments. It's resource-intensive and costly if you try to do it yourself. RoamSecure's OnRoad product suite addresses these concerns.
