  "account": "GTT Communications Inc. recently introduced Defense Halo, a network defense platform powered by artificial intelligence to detect threats on enterprise networks. The platform aims to reduce the time vulnerabilities and threats remain undetected within corporate networks. This launch coincides with an open letter signed by over 100 technology, cybersecurity, and financial services companies, warning that AI-enabled attacks will become more prevalent within months, according to OpenAI Group PBC.\n\nGTT's Chief Product and Technology Officer, Fletcher Keister, stated that every security leader he communicates with is \"fighting the same battle against the clock,\" and AI-powered threats exacerbate the situation. Keister explained that vulnerabilities become more hazardous the longer they remain undetected, and Defense Halo has been designed to uncover and address such weaknesses more promptly.\n\nThe platform comprises two modules: one monitors firewall and device configurations against security frameworks whenever they change, while the other maps known vulnerabilities to specific customer assets and ranks them by priority. AI-generated remediation plans are provided in real-time to close gaps before attackers identify them. The software establishes a behavioral baseline from logs and traffic flows, flagging any deviations in real time and determining whether they represent genuine threats. Confirmed threats can be contained at network speed through automated runbooks on compatible devices.\n\nDefense Halo maintains a live, stateful model of each customer's network, displaying every host-to-host connection in real time, which assists threat hunters working with the platform. The company operates the software on its AI factory, utilizing compute capacity from its global Tier 1 backbone and data centers in the U.S., U.K., and European Union, adhering to data sovereignty requirements. Each customer receives a dedicated, isolated instance of the patent-pending system.\n\nAmy DeCarlo, a principal analyst for security and data center services at GlobalData plc, noted that most security products only analyze traffic after it has been collected and normalized, adding latency, cost, and blind spots. DeCarlo praised GTT's approach of running AI inference within its own network, highlighting its \"architecturally different\" nature. This customer-centric, log-centric platform is positioned beyond endpoint-centric and log-centric solutions, according to DeCarlo. Defense Halo is currently available, and select customers are already utilizing the platform.",
