In theory, consumers and businesses could punish Symantec for these
oversights by contracting with other security vendors. In practice, there’s
no guarantee that products from other vendors are well-secured, either
— and there is no clearway to determine how secure a given security
product actually is.
Too many firms take an "appliance" or "product" (aka 'technology") approach to security. There's a saying that's been attributed to many security specialists over the years but is quite true:
If you think technology can solve your security problems,
then you don't understand the problems and you don't
understand the technology.
Its still true today.
