Secure Internet & SaaS Access (ZIA)

Zscaler Internet Access (ZIA) delivers fast, secure, and reliable access to the internet and SaaS applications, while protecting users from advanced threats and data loss. As part of the broader Zscaler for Users platform, ZIA enables secure access to internet applications, private applications, and provides end‑to‑end digital experience monitoring.

Because most enterprise traffic flows to the public internet, ZIA is one of the foundational components of the Zero Trust Exchange. Let’s look at how Zero Trust capabilities support secure internet access:

When a user connects to the open internet, their traffic is first terminated in the Zero Trust Exchange, where identity, context, and security posture are verified before any connection is allowed. This approach ensures strong security and business value.

With ZIA, organizations gain best‑in‑class, multilayered protection, including AI/ML‑powered phishing and botnet detection, DNS security, high‑scale encrypted traffic inspection, and advanced data protection capabilities such as hundreds of built‑in DLP dictionaries.

Key reasons enterprises adopt Zscaler for Users for secure internet access include:

• Zero Trust connectivity: Ensuring all sensitive traffic flows through the Zero Trust Exchange for full inspection and encrypted‑traffic visibility.
• Optimized local breakout: Efficient handling of UCaaS and productivity traffic like Microsoft 365.
• Zero Trust SD‑WAN enablement: Eliminating legacy routable networks and enabling users to access the internet securely from anywhere using Zscaler Client Connector.
• Broad applicability: The same benefits extend to workloads accessing the internet and IoT/OT devices requiring secure outbound connectivity.
