Details
As part of our effort to provide the world’s most robust and high-performance internet security platform, Zscaler is expanding its global data center (DC) footprint and will soon be offering services from new or expanded facilities at the locations listed below. The expansion of existing facilities will provide the scalability and reliability required to meet the growing demand for global connectivity on our cloud platform along with the following benefits:
- A significant capacity increase, including IPSec VPNs.
- Seamless migration in the future, as the IP addresses used are portable and Zscaler-owned.
- Increased resiliency with multiple transit providers.
- Updated network design with state-of-the-art routers and switches.
