GTT launches AI-native network defense platform

GTT Communications Inc. launched GTT Defense Halo on September 29, 2026, an AI-native network defense platform built on GTT's AI factory and deployed as a dedicated instance per customer. The patent-pending platform proactively identifies vulnerabilities and policy gaps with AI-generated remediation plans, confirms behavioral anomalies as genuine threats in real time, and generates a stateful model of every host-to-host connection for threat hunting. GTT said the platform is hosted in the United States, United Kingdom and European Union to meet enterprise scale and sovereignty requirements.

GTT Defense Halo remediates vulnerabilities before attackers find them and resolves network anomalies into confirmed threats at network speed. pressrelease September 29, 2026 GTT Communications Inc., a leading networking and security as a service provider for multinational organizations, today announced the launch of GTT Defense Halo, an AI-native network defense platform built for a threat landscape that no longer moves at human speed. The patent-pending solution is built on GTT's AI factory and deployed as a dedicated instance for each customer. GTT Defense Halo changes the paradigm of network defense in three fundamental ways: First, it proactively identifies vulnerabilities and policy gaps across the customer's estate and provides AI-generated remediation plans in real time before attackers can discover them. Second, it identifies behavioral anomalies specific to a customer's network and determines in real time whether they are genuine security threats. Genuine security threats can then be remediated at network speed. Third, it generates a stateful, real-time model of a customer's network, visualizing every host-to-host connection and communication, enabling real-time threat hunting and vulnerability exposure assessment. Proactively detecting and responding to vulnerabilities and security threats at network speed is now a foundational requirement for cybersecurity in the AI era. This reality was clearly communicated in an open letter published in late August that has been signed by more than 100 technology, cybersecurity and financial services companies, warning that AI-enabled cyberattacks will become far more widespread and sophisticated and that defenders have a narrow window to prepare. GTT Defense Halo is powered by GTT's AI factory, which is embedded in its global Tier 1 backbone and hosted in the United States, United Kingdom and European Union, to support enterprise scale and sovereignty requirements.
