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). Cisco EPGs can be a physical server, a virtual machine, a Linux container, or even a mainframe. Pitfall #3 : It’s resource intensive. Microsegmentation will fix this.
