Embrace Office 365 and phase- out local email servers 4. Local internet breakouts with appliances 30 Country & Regional HQs 870 Branch Locations MPLS WAN Vendor 9 Data Centers Open Internet IPSEC-to-MPLS architecture (No MPLS at braches) Branch office users were still complaining their internet experience was poor. MPLS WAN Vendor SaaS Benefits • Cost savings • Better internet experience at country and regional HQs • Simplified IT by standardizing email/SharePoint and reducing MPLS vendors from 17 to 1 1 4 MPLS WAN Vendor 2 3

Implement local internet breakouts in all branches 30 Country & Regional HQs 870 Branch Locations 9 Data Centers MPLS WAN Vendor Open Internet Option 1: Deploy branch firewalls in 870 locations. Option 2: Implement Zscaler Cloud Security Platform. XX Office 365 required more than just traditional proxy ports. Visibility provided by Zscaler led to courageous conversations on OSI Models Layers 8,9,10. SaaS Benefits • Reduction in branch user internet complaints (less pushback) • Avoided the cost and overhead of deploying 870 security appliances • 60% reduction in Data Center bandwidth requirements • Enhanced Security Posture – SSL inspection, cloud sandbox, DLP, and SIEM integration

Reduce security appliance requirements at country / regional HQs 3. Protect mobile users 30 Country & Regional HQs 870 Branch Locations 9 Data Centers MPLS WAN Vendor Open Internet Delivered a consistent end-user experience to IaaS and SaaS applications at all branch and HQ locations, but the mobile user was still struggling SaaS Benefits • Eliminated security appliances in country & regional HQs • Better Office 365 user experiences in all locations • Reduced risk by providing identical security controls to mobile workers

Migrate apps to IaaS – re- platform critical apps to be browser accessible 2. Deploy virtual NGFWs and load balancers to eliminate traffic tromboning 3. Consolidate data centers 30 Country & Regional HQs 870 Branch Locations VM Virtual NGFWs and load balancers were expensive, didn’t scale, and micro-segmentation challenges. User confusion on when to use VPN and when they could use a browser. Benefits • Reduced data center costs • Reference Architecture to provide users better access re-platformed apps (No VPN)
