| Being Green |

| The electricity consumption and greenhouse gas emissions caused by computers and the Internet is provoking concern. A recent report by Gartner said the global IT industry generated as much greenhouse gas as the world’s airlines—about 2% of global CO2 emissions. ‘[Traditional] Data centres are among the most energy-intensive facilities imaginable,’ said Evan Mills, a scientist at the Lawrence Berkeley National Laboratory in California. |

| Thsse use of IT equipment has a major impact on energy consumption and on the environment. Companies collectively deploy millions of point products on-premise. This reliance on redundant, outdated and energy-inefficient hardware consumes more electricity than needed, creating a significant carbon footprint. Zscaler is committed to reducing energy consumption to promote a greener environment and our unique technology gives other firms the same opportunity. |
| Cloud Security, SaaS is Green |
| Rather than buying and deploying dozens of boxes on-premise, companies can route traffic through Zscaler’s multi-tenant, centralized data centers. Infrastructure in-the-cloud is better utilized: centralized servers reduce redundant hardware and operate more efficiently, reducing the amount of energy used. Moreover, features such as efficient cooling further increase energy efficiency. |
| High Performance is Green |
| Rather than deploying low performance proxies, which process a few thousand transactions per second, Zscaler has purpose-built high performance web proxies which operate at 50 to 100 times the throughput of a traditional proxy. A higher throughput therefore consumes 1/50th of the energy consumed by a traditional web proxy. |
| Reduce, Reuse, Recycle, Conserve |
| Zscaler is taking the initiative to minimize wasteful consumption. Paper waste is reduced by encouraging double-sided printing or eliminating unnecessary printing. Recycled paper with a high percentage of post-consumer waste is used whenever possible. |
| Conclusion |
| Traditional on-premise solutions require extensive electricity usage and are not designed to reduce their carbon footprints. Thousands of customers individually maintain thousands of appliances operating below maximum performance. Zscaler’s multi-tenant data centers utilize appliances more efficiently and maximize performance to reduce energy consumption. |
