Roadblocks to Security Success
• More than half of attacks result in damages over $500k
• More devices and Greater Threat Complexity
• Budget constraints and lack of trained personnel
• Security product overload!
Nearly half of the security risk
organizations face stems from having
multiple security vendors and products.
Of organizations using 1 to 5 vendors, 28
percent said they had to manage public
scrutiny after a breach; that number rose
to 80 percent for organizations using
more than 50 vendors.

APIC configures FMC 6.2.3, using REST-APIs to manage the following devices:
 Pre-registered FTD devices in either Stand-alone, HA or Cluster mode
APIC configures the following features:
• Interfaces in Routed, Switched, or Inline mode. Defines VLAN sub-interfaces
(including Port-Channels) for Routed and Transparent firewall mode, including IRB.
Static routes can be added under interface configuration.
• Security Zones, Interface Names, Inline Sets, as specified in function profile
parameters. FMC names are prefixed with APIC Tenant and registered FTD device
name. EPG learning feature is supported with FMC.
• Assignment of the Security Zones to pre-configured ACP Rule(s).
