During the initial test of v7.6.4 build3596 with IPS v7.01154 (33.00064), NSS Labs was able to bypass protection using Layer 4 TCP evasions. Following receipt of test results published on November 5, 2025, Fortinet responded quickly to develop an updated IPS package (v7.01165 (33.00064)) that NSS Labs then tested using the identical test methodology and tools employed in the original evaluation.

This document provides updated test results for the Fortinet FortiGate-200G Enterprise Firewall utilizing IPS signature version v7.01165 (33.00064).

Product ratings give decision-makers clear, forward-looking insight into the effectiveness of products tested. The Comparative Security Map (CSM) assesses Enterprise Firewall products based on Security Effectiveness and False Positive Accuracy.

Products with high Security Effectiveness and False Positive Accuracy are given ‘Recommended’ ratings. Products rated ‘Neutral’ can still be suitable for organizations that can tolerate a slightly higher level of false positives. Products receiving a ‘Caution’ rating have below-average Security Effectiveness and should be reviewed for potential alternatives.
