• Become the norm for branch and tertiary locations

• Restricts Internet access using premium IP-MPLS bandwidth

• Ideal for Guest WiFi or Public Cloud Services such as Office 365

• Capitalises on best value 4G, xDSL and FTTx connectivity.

Just like computing, networks are evolving

from fixed to software defined and virtualised

Enterprise Benefits: Move faster, reduce costs, improve customer experience

Virtualisation | New ways to connect and access functions

From: Many appliances, slow and costly. complex to

integrate

To: One appliance, multiple functions, central or

Benefits to enterprise

Cost efficiencies: consolidate appliances, reduce operating

costs, share cloud based functions between users/locations

Agility: make changes, scale up/down, on-demand
