Customer Testimonials

  • Diane Pittman, Data Concierge, Babst, Calland, Clements & Zomnir, PC
    "We've found Discovery Attender to be an absolutely essential tool for eDiscovery, with uses far beyond searching Outlook emails. It's got a great UI, and we especially like the robust search-builder. We've found it useful for non eDiscovery tasks as well, such as file-type analysis, general searching, moving and copying. We're still trying out the new de-duping features and are pleased with how they function."
  • Mark Gainer, Director of Information Technology, Banker Steel
    "Sherpa's eDiscovery solution enabled us to save in excess of $9,000 in forensic and legal fees, and we are still expanding our use of the product. Beyond the bottom-line cost savings, we have been thrilled by the knowledge and professionalism of Sherpa's support staff, which has helped us to maximize the effectiveness of their solution. The low cost and high quality of the people and product have made our investment in Sherpa a great one."
  • Mark Mrotek, Information Security Manager, Universal Technical Institute
    "We've been a Discovery Attender customer for years, use it from time to time, and it works consistently - every time. We were recently hit with a high-visibility, time-critical eDiscovery request that required us to perform far more exhaustive and granular searches than before. I contacted Tech Support, and not only were they helpful in assisting with correcting some long-time-poor Search practices that we were employing, but they offered a 1-hour training session to cover Discovery Attender use and administration. Within minutes it was clear just how many features we were not using - all included with the core product - that made the [seemingly impossible] eDiscovery request borderline simple. Bottom line, once the features of Discovery Attender were used as the Sherpa developers designed, it opened countless doors and options that weren't previously utilized. We now use the product for more than periodic Discovery requests. It has become an irreplaceable tool in our systems administration processes."
  • Joel Commaford, Network Administrator, Nott Company
    "I would say Discovery Attender is unique in that it is the only tool I saw that allows me to search for all types of items from the same interface (files, mail items, offline archive mail, etc.). It does everything I wanted it to do and was easy to set up and use. The service Sherpa Software offers to get you up and running with training is also unique - it was very easy to reach support for any questions I had. They want you to use their software, but equally important is to know "how" to use the software. I would comfortably recommend Discovery Attender."
