Sojourner - You most likely have had attacks. You just don't know it because ZA has not told you. That could be from the settings you have in the program.
As an example, about 3 years ago several students at UNC-CH tried quite a few times to get into my computer. Using ZA logs alone gave me no clue who was doing this. But, with VZ, I was able to track down where it was coming from ... right down to the physical longitude & latitude.
When I first contacted UNC-CH computer authorities, they said the ZA logs didn't give them enough info to track down who on the campus was doing this. With the physical information & logs given from VZ, the attacks stopped.
And, if you are often getting attacks from certain companies or individuals, you can report these to agencies that track and report the offending companies and/or individuals. But, please make sure these need to be reported before doing so. It may be better to first contact the source as I did in the above example.
