What Does Zscaler Track?

Zscaler is a cloud-native security platform that acts as an intermediary for your internet traffic. When you use a device protected by Zscaler, all your internet requests are routed through Zscaler's cloud. This allows Zscaler to inspect this traffic for security threats and enforce organizational policies before it reaches its destination or returns to your device.

How Zscaler Works

Zscaler operates by inspecting every byte of internet traffic that passes through its cloud. This is achieved through various deployment methods, such as a Zscaler client connector installed on endpoints or by redirecting network traffic at the gateway. Once traffic is within the Zscaler cloud, it undergoes multiple security checks.

What Information is Monitored?

Zscaler monitors a range of information related to your internet activity. This includes, but is not limited to:

• Website Visits: Zscaler logs the URLs of websites you access. This helps in identifying potentially malicious sites or sites that are against organizational policy.
• Content Inspection: Zscaler can inspect the content of web pages, emails, and file transfers to detect malware, sensitive data, or policy violations.
• Application Usage: It can identify and monitor the use of various applications, especially those that access the internet.
• Data Transfer: Information about the volume of data being uploaded and downloaded can be tracked.
• Security Events: Zscaler logs security-related events, such as attempts to access blocked sites, malware detections, or policy violations.
• User and Device Information: To associate traffic with specific users and devices, Zscaler may log usernames and device identifiers.

Why is this Information Tracked?

The primary purpose of Zscaler tracking internet activity is to enhance security and ensure compliance with organizational policies. Key reasons include:

• Threat Prevention: By inspecting traffic, Zscaler can block access to known malicious websites, detect and quarantine malware, and prevent phishing attempts.
• Data Loss Prevention (DLP): Zscaler's DLP features can identify and prevent sensitive data (like credit card numbers or personal information) from leaving the organization's network.
• Policy Enforcement: Organizations use Zscaler to enforce acceptable use policies, such as blocking access to social media, streaming sites, or other non-work-related content during work hours.
• Compliance: Tracking can help organizations meet regulatory compliance requirements by logging internet activity and demonstrating that security measures are in place.
• Performance Monitoring: While not its primary function, some level of traffic analysis can help in understanding network usage patterns.

Privacy Considerations

It's important to understand that Zscaler is typically deployed by employers or educational institutions to secure their networks and data. The extent of tracking and data retention is determined by the organization's policies. While Zscaler itself is a security tool, the data it collects is managed by the deploying organization. Employees and users should be aware of their organization's IT and privacy policies regarding internet usage and data monitoring. In most corporate environments, this level of monitoring is considered standard practice for security and operational reasons.

For personal devices not managed by an organization, Zscaler might be used voluntarily for enhanced security. In such cases, the user has more control over the settings and data collection, but the core security functions remain the same.
