The problem is that threat actors are able to get through the castle gates (firewalls) and once in, are able to evade the castle guards (IPS). The argument is that today with the expansion of n-tier distributed systems and massively parallel architectures, east-west traffic has increased exponentially. Microsegmentation will fix this.
