We test for vulnerabilities on an ongoing basis to ensure that these applications remain protected.

"Now we've got a tool for connecting the dots rather than reacting to each one. We can focus discussion on the big picture."

"Group MarketShare offers the opportunity for fundamental change in this industry. Rational competition is the key to avoiding commoditization, serving new markets, and providing consumers with more choice."

Division President

"What I like is the fact that we have real, objective data rather than speculation to make decisions on. This helps us sift through anecdotal feedback from the field so we know where to focus."

Sales VP

"Intuitive. Easy to use. This is very cool!"

Competitive Intelligence Analyst

"These reports provide excellent information. Feedback has been very positive! We would like the same reports for the next offices on this list."
