CISN2


CISN Enterprise Communications is TOWARDEX Company's internal IT organization that provides solutions to empower business partners across departments and deliver services more efficiently and effectively. CISN's mission is to support and empower our company's employees by providing prompt, sustained technology dominance across the full range of network services and field communications in support of our engineers.

CISN2 (Corporate Information Systems Network, AS25623) initially grew out of the need for TWDX IP NOC personnel and contractors to better manage our infrastructure. Leveraging TOWARDEX's regional network assets, CISN2 lights its own dedicated fibers and lambdas on company-owned dark fiber infrastructure. CISN2 ensures survivability and assured operator access by maintaining independence from TWDX network elements that are providing revenue services.

CISN2 also operates its own independent L2/L3 VPN (and now EVPN) infrastructure over MPLS overlay. This allows multi-tenancy and virtualization of the IT services network to meet variety of use cases and information security requirements. CISN2 maintains its own Amazon AWS DirectConnect and Azure ExpressRoute interconnects to facilitate internal communications to IT workloads in the cloud.
