Cisco.

Cisco has been the default answer to "what switch" for forty years, and the reason is rarely the hardware on its own: it is that a Catalyst is what a consultant writes into a specification and what an auditor expects to find in the rack. Switching, wireless and the Secure Firewall range are what moves through here, alongside Meraki where a site wants cloud management rather than a controller. Sourced through the official channel, which on Cisco matters more than on most: the smart account, the licence tier and the support term have to be right at the order, not discovered afterwards, and that is the part our team settles before quoting.
