As part of a comprehensive zero trust solution, it is crucial not to blindly trust any users or systems. All interactions must be not only authenticated and authorized, but also inspected for inappropriate content. This ensures even approved users are not acting maliciously and that applications are not used to compromise internal enterprise users.

Zscaler Private Access™ (ZPA), the industry’s first AI-powered ZTNA, delivers zero trust access for all users with direct connectivity to private applications while minimizing the attack surface by hiding apps behind the Zscaler Zero Trust Exchange™ platform, eliminating lateral movement using AI-powered user-to-app segmentation and protecting against sophisticated attacks with integrated traffic inspection, application, and data protection.

Internal users are often unwisely given a higher level of trust that can be abused by attackers, who are getting more sophisticated and determined. A recent example showed that some sophisticated groups of state-sponsored attackers gained access as internal users. The Verizon 2024 Data Breach Investigations Report notes a sharp uptick in recent breaches involving internal actors (see below).

And whether they are intentional breaches by malicious insiders or unintentional breaches by careless employees, the picture is clear that internal actors are often involved, and enterprises need to protect themselves from that risk. According to the report, “Nobody wants to believe their employees will do them dirty, but if it happens, do you know how your organization would detect it? If you don’t, you’re not alone, and it may have already happened.”

What is ZPA Threat Inspection?

ZPA Threat Inspection enables enterprises to inspect private application interactions to ensure users, applications, and data are all secured. This includes applying our AAA-rated Zscaler cyberthreat protections, such as firewall controls, malware protection, sandboxing, IPS, browser isolation, URL filtering, and data protection for all application access, whether private applications or on the public internet. It takes just a few steps to set up this protection and ensure your enterprise users are secure, no matter which applications they are accessing.

Key benefits:

Provide protection to private applications against insider threats
Provide protection to users against compromised or malicious private applications
Leverage a unified security and data protection posture for securing Internet/SaaS traffic and private application traffic

ZPA Threat Inspection in action

One of the many cyber protection capabilities that ZPA Threat Inspection offers is Malware Protection. As part of Internet Access protection, Malware Protection can inspect file uploads and downloads for malware in a variety of protocols and take action per violation.

Optionally, administrators can enable TLS Inspection as well to monitor for threats in encrypted traffic. TLS Inspection can be applied broadly or granularly based on specific criteria (e.g., specific applications, specific users), so the administrator can retain full control over when and where protections are enforced.

With just the Internet Access protection in place, this policy will apply only to public internet applications. But we can apply that same strong set of protections to private applications with just one more step. Enabling the “Inspect Traffic with ZIA” setting will ensure all traffic on a given application segment is inspected for malware signatures in both the upload and download directions, keeping users safe as they download files, and protecting private apps from uploads of malicious content. Administrators can enable this inspection per application segment that needs protection against malware, as shown below.

If a malicious actor manages to get malware onto a private application, users will see a customizable warning message if they try to download the malicious content, and the download will be prevented. An example of a customized message is shown below.

In addition to a streamlined configuration that applies the same protections to public and private application access, security event reporting is also integrated. With integrated reporting on public and private application threats, administrators can gather critical insights into their enterprise across all user interactions. Whether looking for all recent application interactions for malicious or possibly infected users, or simply the names of identified malware, the data is available to analyze the security events and take action.
