GTT launches Defense Halo to hunt for threats on enterprise networks with AI. Networking and security services provider GTT Communications Inc. today launched GTT Defense Halo, a network defense platform that uses artificial intelligence to hunt for threats on enterprise networks. Defense Halo is aimed at shrinking the time vulnerabilities and threats go unnoticed on corporate networks. GTT tied the launch to an open letter signed in late August by more than 100 technology, cybersecurity and financial services companies. Organized by OpenAI Group PBC, the letter warned that AI-enabled attacks would become far more widespread within months. GTT Chief Product and Technology Officer Fletcher Keister said every security leader he speaks with is "fighting the same battle against the clock," and AI-powered threats make it harder. A vulnerability gets riskier the longer it goes undetected, according to Keister, and Defense Halo was built so customers could find and act on such weaknesses much sooner. On the vulnerability side, one module checks firewall and device configurations against security frameworks whenever they change. A second module maps known vulnerabilities to the specific assets a customer runs and ranks them by priority. Remediation plans generated by AI come back in real time, with the aim of closing gaps before attackers discover them. Detection is tuned to each customer's own network. The software builds a behavioral baseline from logs and traffic flows, and any anomaly that strays from it gets checked in real time to decide whether it amounts to a genuine threat. GTT says confirmed threats can then be contained at network speed through automated runbooks on compatible devices. The platform also keeps a live, stateful model of the customer's network showing every host-to-host connection. Threat hunters can work from that picture in real time, and the same model feeds the platform's exposure assessments when a new vulnerability surfaces. GTT runs the software on what it calls its AI factory, compute capacity built into its global Tier 1 backbone and hosted in the U.S., the U.K. and the European Union to meet data sovereignty requirements. Each customer gets a dedicated, isolated instance of the patent-pending system. Amy DeCarlo, principal analyst for security and data center services at GlobalData plc, said most security products only analyze traffic once it has been collected and normalized, which adds latency, cost and blind spots. She described GTT's decision to run AI inference inside its own network as "architecturally different." Paired with isolated customer models and in-region data residency, DeCarlo said, the result is something endpoint-centric and log-centric platforms "are not positioned to match." Defense Halo is available now, and GTT said select customers are already running it. Image: siliconangle/gpt image 2.5.

GTT launches GTT Defense Halo, an ai-native network defense platform. ARLINGTON, Va., September 29, 2026 GTT Defense Halo is redefining network security for enterprises with converging network, cloud and security operations by remediating vulnerabilities before attackers find them and resolving network anomalies into confirmed threats at network speed. 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. "Every security leader I speak with is fighting the same battle against the clock. AI-powered cyber threats complicate and intensify that battle," said Fletcher Keister, Chief Product and Technology Officer, GTT. "Time is the enemy because time equals risk. The longer a vulnerability remains undetected in an enterprise network, the greater the risk of breach and exploitation. We built GTT Defense Halo to combat this risk and help our customers understand and act quickly on previously undetected vulnerabilities in their network." 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. "Most existing security products analyze traffic after it has been collected and normalized, which builds latency, cost and blind spots into the architecture," said Amy DeCarlo, Principal Analyst, Security and Data Center Services, GlobalData. "Integrating GTT Defense Halo into your security architecture eliminates these blind spots. GTT is doing something architecturally different by placing AI inference inside the network and AI factories it owns, which marks a significant step in GTT's evolution as a security provider. Combined with customer-isolated models and in-region data residency, GTT Defense Halo gives enterprises a defense platform that endpoint-centric and log-centric platforms are not positioned to match." GTT Defense Halo is available now, with select customers already using the platform. Additional information is available here: GTT Defense Halo.
