The Challenge

Zscaler Internet Access (ZIA) protects users as they access the internet and SaaS applications by enforcing security policies in the cloud. It provides URL filtering, SSL inspection, threat protection, and outbound firewall controls that inspect and regulate internet-bound traffic.

But Zscaler policies across URL & Cloud App control, SSL inspection rules, firewall control policies, and forwarding configurations can drift over time, leaving gaps where malicious traffic, risky destinations, or unauthorized outbound connections can bypass intended protections.

Harden URL & Cloud App Control Policies 

ZIA relies on URL & Cloud App Control Policies to control access to websites and SaaS applications. Reach analyzes these policies to identify overly permissive rules, risky app allowances, and exceptions that weaken enforcement. It also highlights rule precedence issues that override stronger restrictions. Strengthening these controls helps block malicious domains and unsanctioned cloud services.

Ensure Complete SSL Inspection Coverage 

Most threats are delivered through encrypted traffic. ZIA’s SSL Inspection policies decrypt HTTPS sessions to detect malware and phishing. Reach evaluates inspection coverage, certificates, and bypass rules to identify traffic that avoids inspection. It also highlights gaps across users, locations, and applications. Closing these gaps ensures encrypted traffic is consistently inspected and threats cannot hide.

Strengthen Firewall Control and Outbound Access Policies 

ZIA Firewall Control Policies regulate outbound traffic and prevent unauthorized connections. Reach analyzes firewall rules, destination allowances, and protocol controls to identify overly permissive access and unnecessary external paths. These gaps can enable command-and-control traffic or data exfiltration. Tightening these policies helps reduce attack surface and restrict unauthorized communications.

Activate Advanced Threat Protection and Sandbox Analysis 

ZIA provides Advanced Threat Protection, including sandbox analysis and malware inspection for suspicious downloads. Reach analyzes these configurations to identify gaps where sandboxing, file inspection, or detection policies are not fully enforced. It also highlights where malicious files may bypass inspection. Activating these protections ensures advanced threats are detected and blocked before reaching users.
