A primary business risk introduced by legacy firewalls is performance issues. Traditional firewalls are often unable to efficiently handle modern high-volume and encrypted traffic, leading to latency, bottlenecks, and reduced network performance. This negatively impacts user experience and security posture. The study guide points out that legacy firewalls struggle with scalability and speed in today’s cloud-centric environment, making performance a key concern.

Trusted Networks in Zscaler are defined using network-specific parameters such as DNS Server, Default Gateway, and Network Range, which are used to identify known internal networks. These properties help Zscaler Client Connector recognize when a device is on a corporate network. Org ID, however, is unrelated to the network characteristics and is instead associated with tenant identification in Zscaler’s cloud infrastructure.

Cloud Application policies offer deeper, application‑aware controls, such as granular actions on specific SaaS functions, making them a superior choice for managing access to modern web apps compared to generic URL filters.

Posture Profiles give a comprehensive view of a device’s security state - checking OS version, patch level, antivirus status, disk encryption, and more - making them the richest criteria for trust decisions in access policies for sensitive private apps.

You need at least two App Connectors per data center to ensure high availability and load distribution, so with four data centers the minimum total is eight.

For a unified, seamless experience - and because ZPA only supports SAML while ZIA’s recommended authentication is also SAML - you should configure SAML‑based SSO on both ZIA and ZPA. This ensures one consistent identity flow and eliminates multiple credential prompts across the platforms.

When you configure a URL Filtering rule with the Caution action, the only HTTP methods you can select for that rule are CONNECT, GET, and HEAD.

The primary role of Sandbox functionality is to detect and analyze zero‑day and other unknown threats by executing suspicious files in an isolated environment before they reach users.

Zscaler Risk360 quantifies risk by computing a risk score that is based on the number of remediations needed in comparison to the industry peer average. This approach allows organizations to understand their relative security posture by evaluating how many issues require remediation and benchmarking that against peers in the industry. This methodology enables prioritized risk management and provides context around the urgency and scale of remediation activities necessary to reduce risk.

Unlike simply counting risk events or focusing on time to mitigate, Risk360 uses this comparative remediation-based scoring to give a comprehensive view of risk. It does not compute separate scores for each of the four breach stages but rather aggregates remediation efforts and benchmarks them to industry standards.

This is confirmed by the study guide's explanation of Risk360's scoring method, highlighting the use of remediation counts compared to peers as the basis for risk scoring.
