• 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
