zScaler Operation Guide: Delivering Value through People, Process, Service, and Technology

zScaler is a cloud security platform that offers real-time scanning to protect against various online threats. The deployment involves visualized traffic pathways, and troubleshooting includes tools and resources for performance optimization. The zScaler app's functionality is tied to network status and DNS configurations.

  2. What is What is zScaler zScaler? ? • Real time scanning of traffic between users and the internet to protect against: • Virus/Malware • Spyware • Botnet • Inappropriate content • Phishing sites • More ‘real time’ than antivirus as zScaler nodes are continually updated with threat intelligence so that new threats are blocked immediately to all users without updates needing to reach the client • Good summary video Delivering Value through people, process, service and technology

  3. Deployment Visualized Deployment Visualized Traffic to Internet Handoff to Azure Network IPSec to Primary ZEN IPSec to MPLS IPSec to Secondary ZEN AT&T Netgate Mobile User Bacardi Office Delivering Value through people, process, service and technology

  4. zScaler zScaler Agent Agent Private Access Only seen by authorised users Logout & Turn Off Password protected functions, password will only be released in emergency and must be kept confidential Connection Status ON – When working remote OFF – On corporate network Will be ON for locations without ANIRA Delivering Value through people, process, service and technology

  5. zScaler zScaler Agent Agent Export Logs If requested for support purposes Restart Service Used to restart the Windows service if needed Repair App Only use if instructed Notifications Here you can see basic log information for the app status Update App Should not be required – app updates controlled centrally Update Policy May occasionally be needed if a rule is modified and it needs to be applied immediately Delivering Value through people, process, service and technology

  6. How is it deployed? How is it deployed? • Locations with AT&T Netgate/ANIRA (not Cisco ANIRA) • IPSec Tunnel to AT&T for network access (backup or primary) • 2 x IPSec Tunnel to zScaler nodes in country or proximate country • Locations without AT&T Netgate ANIRA • zScaler Agent will be ‘always’ live and route traffic from client to zScaler • Users outside of the office • zScaler Agent will become ‘live’ outside of the Bacardi network and route traffic from client to zScaler Delivering Value through people, process, service and technology

  7. Troubleshooting Troubleshooting http://ip.zscaler.com http://ip.zscaler.com This should be your first port of call for any troubleshooting Client and Gateway Details Delivering Value through people, process, service and technology

  8. Troubleshooting Continued Troubleshooting Continued Performance should be broadly similar to raw internet, potentially with a little extra latency which should not be noticeable during normal browsing. On contended networks (in the office when there are other users browsing) you should not expect to see the full circuit performance. Delivering Value through people, process, service and technology

  9. Troubleshooting Continued Troubleshooting Continued This allows you to download an advanced testing tool (requires Java) which can test page load times and latency of all hops enroute to the ZEN Node. This should rarely be installed on user computers without guidance from Network & Collaboration Team Delivering Value through people, process, service and technology

  10. Troubleshooting Continued Troubleshooting Continued Once you know the ZEN Node you are connected to, you can check it’s health though ‘Cloud Health’ Delivering Value through people, process, service and technology

  11. Frequently Asked Questions Frequently Asked Questions Q. How does the zScaler app know if the machine is on/off Bacardi network A. By looking at DNS servers • DHCP DNS for all ANIRA sites has an additional DNS server configured 10.137.39.56. When this is present the client knows that it is on Bacardi network and disables the agent Delivering Value through people, process, service and technology
