Shouldn't be surprising or news to anyone who has looked directly into an
access.log, all servers are constantly being probed by bots, crawled by
spiders, etc. The incapsula "article" is some combination of marketing and
FUD, even though the title is true.

Using a second form of analytics never hurts. If you have a webserver, run
analog on your own log files. Understand that GA only counts accesses when a
client accessing your server also executes the javascript code on your site
and successfully accesses their site.

Note that many hosting sites do not give you access to error logs, or only
provide a web interface to show some of the most recent error messages.

A better title is probably "Google Analytics doesn’t show you 51% of website
noise"
