eValid -- Success Story -- Virtual Private Network (VPN) Validation
eValid Home
Success Story Summaries

Synopsis
A manufacturer of a Virtual Private Network (VPN) appliance has been using eValid to generate large amounts of web browsing traffic to confirm the quality and reliability of their equipment when applied in "real world" usage.

Background
Many companies offer Virtual Private Network (VPN) appliances that use various technologies to provide secure SSL-based access and use of web applications. A key factor is that in most cases secondary processing of delivered HTML material -- the material that is sent over the wire through the device processing -- requires validation to make sure that what the user sees with the VPN appliance is the same as what is seen without the VPN appliance.

eValid Application Description
The eValid system makes it easy to generate a regression suite that is tuned to detect, insofar as possible, important changes that affect web behavior and at the same time to disregard inconsequential changes.

Once the functional test suite was completed our customer put all of the tests under eV.Manager control for easy repetition and re-confirmation of their appliance after changes were made to their processing algorithms.

eValid Features Used
This project used eValid's functional test and page validation capabilities, and relied on the ability of eV.Manager to control large numbers of tests. In addition, there was significant use of the eValid PageMap utility to reveal the internal contents of the DOM image of each page.

Results Achieved
Over a period of several quarters, our customer identified major technical issues with the behavior of their VPN appliance when applied to real-world browsing and use of commercial, public websites. One outcome of their work was a major architectural change to a critical internal component for which the observed failures would have affected their ~$1B VPN appliance market. Savings estimate: ~$2,000,000.
