Asking what is the best cybersecurity technology is like asking what is the best prescription medication – There simply is no one best cybersecurity product or prescription medication, because what is "best" is highly dependent upon the specifics of a particular situation in which it is being applied.
Also, consider that the feature and functionality differences between competing offerings in the same category of cybersecurity countermeasures are rarely, if ever, the primarily reason that a person, business, or government is able to be successfully breached.
In most cases, if not in all cases, how well you use cybersecurity technology is going to be far better predictor of your chances of remaining secure than would be which particular reliable vendor’s offering you choose to use.
