I joined the organization before they made the decision to go with Symantec. They have or have still another antivirus like Norton Security Premium in some instances. This does not change my opinion of Symantec.  

We're currently looking at another solution that is not as expensive. I sometimes do use Calico Control. I find the software on the solution is better than Symantec.

We work with Trend, and McAfee together. We no longer use Symantec.

In my experience, I have seen that people tend to keep changing their cybersecurity products every three or four years.
