a DDOS cannot be stopped easily by small companies. they can promise you alot but in fact, they cannot deliver. that's why a REAL ddos protection is expensive. the rest of them are just useless imitations or pure scams because they have fake advertising.
I agree with your argument. DDOS is an attack that carried a lot of people against one particular object.
The world is almost no one can avoid the DDOS. even large companies ever attacked by DDOS.
