The main issue would be to find out what brand names they demand
a user of a recent model Apple computer running OS X 10.11.4+ is
supposed to purchase in order to continue their studies or conduct
business, on these web site portals.
https://www.internetsafetyproject.org/wiki/onguard-online fails to impress.
To search online: only opens up the door of popularity or that of business
and advertisement driven false-popularity, as those can be bought so as
to appear truthfully the Best. -- That's too much like searching for products
such as 'cleanmymac' and hope it really is good, only because of the number
of times in each search result page the nonsense and false claims, appear.
Does it pay to be popular, or does popularity pay? Either way it costs too much
if the product is false and drags the performance down so low that other false
products get promoted in marginal offers to 'clean' or 'make it faster' adverts.
There are a few items in the Mac App Store, which may or may not qualify as
a practical and prudent method of securing the OS X from untoward attack...
Since the qualifier is not necessarily that a product perform beyond a doubt.
{And the measure of doubt, is enhanced when performance is hampered;
the actual operating system itself is damaged by these posers of truth.}
Even using different search engines can change the results; plus modifiers
such as bolean and other custom means to alter the search results. My
first choice is 'duckduckgo' since it doesn't track; however word order and
other text can be required to obtain other desired results; & hopeful 'facts'.
In any event, the odds are factual protection will have a limited ability to do
more than act like a filter; those tend to obstruct &/or damage the new OS X.
{On the other hand, there are a few items that are helpful, free; such as
etrecheck.com, https://www.malwarebytes.org/antimalware/mac/ & etc.}
While I can see there is an alleged desire to prevent issues from becoming
greater than they may otherwise could be, if nothing is done at all, a matter
of practical importance is dumped on our collective doorsteps by a demand
we use a new 'blanket approach' to Solving a Problem. The built in one is OK.
And better when people know how to harden their own computer's OS X. 😐
