SSL versus IPSec

Secure Sockets Layer (SSL) for remote access is based on a simple concept: use the encryption and authentication capabilities built into every Web browser to provide secure remote access to corporate applications.

An irony of SSL VPNs is that their greatest asset-browser-based access is also their most problematic feature. The freedom and mobility of the browser means that your users can run applications and access network resources from just about anywhere a partner site, an airport kiosk, an Internet cafe, even a friend's house. While that freedom may boost productivity, it also exposes your network to an unlimited number of computers whose security state is unknown and unknowable. Your network may experience increased risk from viruses, Trojans, and other malicious code, such as keystroke loggers.

Browser-based access has other complications as well. Default user authentication is limited to a username and password, which is notoriously insecure.

Let's suppose that the IPSec VPN Client stays light, that it is possible to download it with prearranged network configuration, that it is possible to make the user interface invisible and that the user just needs to insert its USB Stick (USB Flash Drive) with certificates inside to automatically launch connections (i.e. tunnels) then IPSec technology only differentiate itself by a stronger level of security.

Please have an overview on both side issues and how TheGreenBow brings together strengths of both worlds in its software:
