Business continuity and increased resiliency


High performance
Cisco ISR 4321 features a distributed multicore architecture with internal services plane.

Lower WAN expenditures
Embedded IWAN solution is designed for creating lower-cost,business-class Internet connections.

Superior and secure user application experiences
Secure boot feature performs hardware-based authentication of the boot loader software to prevent malicious or unintended software from booting on the system. Code signing verifies digital signatures of executables prior to loading to prevent execution of altered or corrupted code. Hardware authentication protects against hardware counterfeiting by using an on-board tamper-proof silicon,including field replaceable modules. If authentication fails,the module is not allowed to boot.

IT consolidation,space savings,and improved total cost of ownership (TCO)
Single converged branch platform integrates routing,switching,virtual server,storage,security,unified communications,WAN optimization,and performance management tools.

Business continuity and increased resiliency
Cisco ISR 4321 features modular network interfaces with diverse connection options for load-balancing and network resiliency and modular interfaces with online removal and insertion (OIR) for module upgrades without network disruption.
