About this network

One of Zscaler's Autonomous Systems (ZSCALER-INC). Zscaler runs a global cloud security platform (SASE / Secure Web Gateway) that enterprise traffic is routed through on its way to the internet, so an IP here is a security-proxy egress, not a datacenter server or an end user's own address.

What it's used for

• Egress for Zscaler Internet Access (ZIA) — inspecting and filtering outbound web traffic for corporate customers from cloud enforcement nodes.
• Zero-trust access to private apps (Zscaler Private Access, ZPA).

Notable

• Previously catalogued as hosting; it is reclassified as business because what transits it is corporate end-user browsing behind a multi-tenant proxy, not datacenter servers.
• Related Zscaler networks: AS22616 ZSCALER-SJC1, AS32921 ZSCALER-NEWYORK, AS40384 ZSCALER-GRX, AS53444 ZSCALER-SJC, AS62044 ZSCALER-EMEA, and AS62907 ZSCALER-CORP.

Interesting

• One shared egress carries thousands of distinct users, so an IP here maps to any of many customer orgs rather than one identifiable company.
