Cisco
Well suited for building management networks across the organization as it has been reliable without much downtime. Since it has great switching qualities, it suites well for data center and end-user connectivity using access switches. It might not be the best for routing, as other XOR software has proven to be superior for routing.

When we evaluated them for a proposal to core networks we decided to go with other vendors, as the processing capacity of core routers was lower. Typical environments Junos OS has fit in our organization are enterprise, customer edge, distribution networks.
