Over the past 4 years, we have utilized Zanacore Technologies for all of our IT needs. We initially used them only when something broke! After a couple years of being reactive and with anticipation of a major electronic medical record (EMR) implementation we signed a contract with Zanacore for their NetGuard proactive support. At the time I was leery about signing a contract and committing to a predetermined amount every month. After all, that was just another added expense especially during this terrible economy. Looking back now, I am glad we did.
