Two Six Technologies launches Sentr, AI-powered command center for information warfare

Two Six Technologies has launched Sentr, a command centre platform for information operations that uses AI agents to identify communication opportunities and execute targeted campaigns. The system integrates with existing government tools and can plan campaigns in hours rather than weeks, with early users reporting 85% time savings. Built on Two Six's agentic orchestration layer, Sentr processes large datasets to deliver tailored content to target audiences globally, including in restricted environments. The platform is already deployed with Department of War, Department of State and Intelligence Community customers. The Herndon, Virginia-based company, formed in 2021 by Carlyle Group, employs approximately 900 professionals supporting national security missions. Sentr generates clickable citations for audit trails and scores AI outputs against doctrine-based evaluation frameworks to reduce unreliable recommendations.

Two Six Technologies debuts Sentr, a command center for information operations.

Two Six Technologies debuts Sentr, a command center for information operations. Two Six Technologies has launched Sentr, a command center platform for information operations that consolidates research, planning and campaign execution into a single chat interface. The platform uses AI agents to process large datasets, identify communication opportunities, generate action plans and deliver targeted campaigns, including in restricted information environments. Users can plan and execute campaigns in hours rather than weeks, with some reporting an 85% time savings. "As a company dedicated to critical missions of national security, Two Six is proud to introduce Sentr, a unique product that enables our U.S. government partners to establish dominance over the narrative battlefield," said Joe Logue, CEO of Two Six Technologies. "Sentr combines agentic AI with a comprehensive command center model to deliver targeted actions and create strategic advantage in the information environment, which allows our partners to complete their missions faster and more effectively than ever before." The platform is already deployed with the departments of War and State and intelligence community customers. It generates interactive, clickable citations for every document used, preserving an audit trail. Interactions with Sentr's large language model are never exposed to third-party endpoints. "We frequently hear from our government partners that they rely on us when they're ready to take action and need to drive change in the real world through information operations," said Becky Fair, chief product officer of Two Six Technologies. "There are countless tools for simply monitoring the information environment, if you want to know what already happened. Sentr is for those who are ready to shape what happens next." Sentr builds on Two Six's Pulse suite of information operations products. Capabilities include: - A unified interface that guides users from research through creation, delivery and assessment using natural language prompts. Powered by Helix, Two Six's agentic orchestration AI, the platform eliminates the need for analysts and planners to manually stitch together data, tools and large language models for each phase of their workflow. - A consolidated workflow that removes information silos and fragmentation that slow decision-making, combining the ability to identify opportunities with the power to act in a single command center interface. - A single platform that replaces a complex, multi-tool capability stack, reducing the risks and inefficiencies created by multiple niche tools that build bloated architectures and expensive integrations. Sentr lets users research the information environment via curated data feeds - with emphasis on narratives tied to great power competition and other national security priorities - plan a response, such as building the documents required to launch a PSYOP campaign, and execute those plans from one interface. Users move from identifying an opportunity to taking action, all within the same interface. For example, a user tracking how Chinese officials discuss infrastructure projects in Cambodia and how local audiences respond can describe that goal to Sentr, which queries its data lake and surfaces relevant tools. From there, the user can build a messaging campaign to those same audiences, refine it based on what resonates, translate it and deploy it on whichever platform the audience uses most - WhatsApp, Facebook Messenger or others - holding a one- or two-way conversation, live or automated. A process that could have taken weeks now takes hours.

Two Six Technologies named top 10 finalist in NATO Innovation Challenge for Agentic AI in Cognitive Warfare.

Two Six Technologies named top 10 finalist in NATO Innovation Challenge for Agentic AI in Cognitive Warfare. June 3, 2026 Two Six Technologies has been selected as one of ten finalists in the NATO Allied Command Transformation (ACT) and NATO Supreme Headquarters Allied Powers Europe (SHAPE) Innovation Challenge focused on Agentic AI for Cognitive Warfare, placing the company among a select group of organizations helping shape the future of information operations across the NATO Alliance. The challenge attracted more than 100 companies from NATO member nations, all competing to provide innovative technologies that can help NATO counter adversarial influence campaigns, psychological manipulation, and efforts to disrupt military decision-making processes. The initiative marks NATO's 18th Innovation Challenge and reflects growing concern over threats targeting the cognitive domain, where adversaries seek to influence perceptions, shape public opinion, and undermine trust through coordinated information operations. Two Six Technologies earned recognition for its cognitive advantage platform which leverages custom-tailored agentic AI to accelerate the planning, execution, and assessment of cognitive warfare operations. The platform is designed to enhance the effectiveness of information operations teams operating in increasingly complex and rapidly evolving information environments. NATO's selection validates its mission-focused approach to developing technology that helps governments and organizations understand, navigate, and compete in today's information environment. As foreign malign influence campaigns continue to grow in sophistication and scale, solutions that combine human expertise with advanced AI capabilities are becoming increasingly critical. The NATO challenge seeks dual-use agentic AI solutions capable of supporting strategic communications and information operations across five key stages: situational understanding, planning, coordination, delivery, and assessment. Desired capabilities include analyzing complex information environments, detecting shifts in public sentiment, mapping influence networks, and generating communication strategies that can adapt in real time. Importantly, NATO has emphasized that selected solutions must maintain meaningful human oversight. The alliance is seeking what it describes as "human-led judgment plus AI-enabled scale and synthesis," rather than fully autonomous influence operations. Proposed technologies must also adhere to NATO's Principles of Responsible Use for Artificial Intelligence, including requirements for lawfulness, explainability, reliability, and bias mitigation. Two Six's selection as a finalist highlights its potential to support NATO's efforts to achieve information advantage while ensuring responsible and transparent use of AI. The platform's agentic AI capabilities are designed to help operators better understand narrative landscapes, identify emerging influence threats, and evaluate the effectiveness of information operations campaigns. The competition culminates with a finalist pitch event in Rennes, France, where selected companies will present their solutions to NATO leadership and defense stakeholders. Finalists were chosen based on their ability to address NATO's evolving cognitive warfare requirements and provide practical tools for countering adversarial influence operations. For Two Six, the recognition underscores the growing international relevance of its cognitive advantage capabilities and reinforces the company's commitment to supporting NATO and allied partners in confronting emerging challenges in the information environment. As competition increasingly extends into the cognitive domain, where narratives and perceptions can shape strategic outcomes, NATO's investment in agentic AI technologies signals the alliance's determination to maintain information superiority and protect decision-making processes against foreign malign influence.
