2026 Q2 Security Service Edge Zscaler

In Q2 2026, NSS Labs conducted an independent test of the Zscaler Zero Trust Exchange (ZTE) using an early preview of the SSE Threat Protection Methodology v3.0.

How We Tested:

• Malware: 4,873 attack samples sourced from current malware campaigns.
• Exploits: 317 attack samples from widely exploited vulnerabilities in enterprise environments.
• Evasions: 583 attacks spanning 15 evasion techniques.
• False Positives: 4,098 samples from various business-critical files and applications, ensuring security measures did not disrupt legitimate traffic.

These comprehensive benchmarks highlight the effectiveness of the SSE in delivering reliable security effectiveness, operational stability, and minimal disruption to legitimate traffic. Organizations can utilize these results to make informed decisions when selecting an SSE for modern enterprise environments.
