The FUD techniques are certain to come up again and again as they are effective (to a degree).
FUD is a marketing technique to sow fear into cost conscious customers that are thinking of going to a competitor. Pushing safety in numbers and other uncertainty creates FUD in the mind of potential customers. Thus it is not so easy to go with a competitor unless one is armed with knowledge.
the first FUD campaign happened when IBM mainframes finally receive some competition with Amdahl mainframe company.
Above picture is an Amdahl mainframe (with red-hued panels instead of the familiar IBM blue). Newcastle university in picture)
So obviously Newcastle University did not pay attention to FUD by IBM
Why do I mention this FUD business? Because it is an old tactic and is being used by competitor Firewalls in the security firewall market space. Palo Alto is muscling into a larger marketshare (due to developing and running a good firewall operation)
So the competitors have developed a youtube video
First one selects an exploit 
Then configure the test environment which means setting up what kind of attack will be ‘tested’.
then conveniently one can Run the attack.
So the competitor ran the Evader software with specific evasion techniques to see if they can evade the Palo Alto firewall they have set up so they can evade it.
This is exactly why FUD works, make future Palo Alto customers(or current ones) see that they can have a firewall that is not bullet proof.
Yes we know that – no firewall is bulletproof no matter how well you configure it, there is always one item that is missed over the days and years. Since we are assaulted day after day and all the hackers have to do is get one attack to work. We have to be cognizant to not be complacent and invincible (it will not happen to me attitude).
It is true we have better firewalls and the only thing to combat FUD no matter your industry is massive amounts of information, thus knowing what you have backwards and forwards.
