↑ 8%Onebrief announced that its AtomEngine wargaming and simulation platform has received Department of War Impact Level 5, Impact Level 6, and Top Secret authorizations. The platform now offers full feature parity across all three major DoW operational networks. The authorization enables Combatant Commands and Service Components to use AtomEngine across different classification levels without deployment limitations. Users can participate in exercises from any location, eliminating the need to travel for weeks-long sessions. AtomEngine allows operators to simulate all five domains at planet scale within a unified platform. Key capabilities include movement, manoeuvre, fires modelling, multi-theatre operations, advanced logistics simulation, and five-domain integration across air, land, sea, space, and cyber. The deployment was enabled through Second Front's Game Warden platform. Onebrief was recently named one of FastCompany's Most Innovative Companies for 2026.
Onebrief names Second Front as preferred deployment partner following rapid DAF CLOUDworks deployment. Expanded partnership unlocks new capabilities for the Joint Force HONOLULU-(BUSINESS WIRE)-Onebrief today announced an expanded partnership with Second Front Systems following the successful migration of all users at the Secret classification level to the Department of the Air Force (DAF) CLOUDworks environment. "Our transition to DAF CLOUDworks, deployed through our trusted partner, Second Front, marks a pivotal advancement in delivering secure cloud scale infrastructure for military planning." - Grant Demaree, Onebrief CEO Share At a time when military advantage increasingly depends on software and AI, this partnership reflects an important example of the capability to deliver mission software at operational speed and keep it secure over time. The migration establishes a secure, high-performance foundation for Onebrief to deliver agentic AI, advanced wargaming, and real-time decision intelligence to commanders across the globe. "Our transition to DAF CLOUDworks marks a pivotal advancement in delivering secure cloud scale infrastructure for military planning," said Grant Demaree, Chief Executive Officer of Onebrief. "By deploying through our trusted partner, Second Front, we have significantly strengthened the speed, resilience, and scalability of our platform, ensuring America's warfighters maintain uninterrupted access to mission-critical planning tools worldwide. This infrastructure evolution builds on recent milestones, including our acquisition of Battle Road Digital and our acceptance into the U.S. Army's Next Generation Command and Control (NGC2) environment." Onebrief's architecture and infrastructure, now in the Air Force Research Laboratory (AFRL) managed DAF CLOUDworks environment, has been modernized to meet the escalating operational and performance demands of Combined Joint All-Domain Command and Control (CJADC2). This provides significant improvements in security, availability, and performance, along with access to enhanced hardware and cloud services from AWS and Microsoft Azure. The migration deepens a longstanding partnership between Onebrief and Second Front Systems, whose Game Warden platform accelerates the authorization and deployment of software across classified and unclassified government networks. Migration of Onebrief's Top Secret instance is now underway as the next phase of the expanded partnership. Onebrief maintains authorization at IL5, IL6, and Top Secret classification levels. By leveraging DAF CLOUDworks' secure and compliant cloud environment, Onebrief can deliver new capabilities, including advanced AI-enabled workflows, agentic planning tools, and expanded wargaming and simulation features, at accelerated timelines. What previously required months of staging, testing, and manual deployment can now be executed at the pace of modern missions, while maintaining strict adherence to Department of War security requirements. "Onebrief is setting the bar for what modern operational software looks like inside the Department of War," said Tyler Sweatt, CEO of Second Front Systems. "Their decision to make Second Front its preferred deployment partner reflects a broader shift we're seeing across government: mission teams expect commercial software to deploy at operational speed without compromising security or trust." For Onebrief's customers, the migration delivers immediate operational advantages, including seamless interoperability across combatant commands worldwide, and expanded capacity for AI-powered planning and decision support. All collaboration capabilities, user credentials, and custom data fields were preserved through the transition without generating friction for operational planners.

Onebrief expands leadership team with techveteran Cory Ondrejka. February 6, 2026 HONOLULU (Feb. 3) - Onebrief, the operating system for modern command, today announced that it has hired Cory Ondrejka as Chief Technology Officer (CTO). Ondrejka brings to Onebrief more than 30 years of experience inventing and delivering new technologies while leading large engineering teams, including at Google and Meta. As CTO, Ondrejka will lead Onebrief's engineering organization. He will lead the expansion of Onebrief's artificial intelligence-driven support capabilities and integrate advanced wargaming, modeling, and simulation tools through Onebrief's acquisition of Battle Road Digital. This will bring together operational planning, wargaming, and simulation within the Onebrief platform, creating a single, unified environment for military command. He will focus on making these tools intuitive and seamless, enabling teams to plan, test, and adapt at superhuman speeds. "Over the last three decades, Cory has been involved in some of the most important shifts in modern technology," said Onebrief CEO Grant Demaree. "He understands how to turn new ideas into trusted systems. Cory has already been deeply involved in its work strengthening Onebrief's AI Assist capabilities and integrating Battle Road Digital's best-in-class simulation technologies into its platform. His leadership is critical to its efforts to strengthen and scale this platform. He is the right person to lead its technology. "Joining Onebrief feels like a homecoming," said Ondrejka, a graduate of the United States Naval Academy. "The team is solving real problems for military planners, by incorporating AI into a platform that unites planning and wargaming in one unified system. As we integrate Battle Road into the platform, I'm looking forward to continuing the work of building technology that our nation's military leaders can trust when it matters most." Ondrejka has held senior leadership roles across both early-stage companies and some of the world's largest technology organizations. As vice president of Google Experience, Ondrejka served as Google CEO Sundar Pichai's technical strategy advisor and led engineering teams of more than 1,500 people. His responsibilities included improving core consumer technologies and helping teams apply AI across widely used products. Ondrejka also served as vice president of Mobile Engineering at Meta during the pivotal period when Facebook was shifting from a desktop-focused product to a mobile-first platform. As a leader at Meta during this transformation, he created the technology and product experience that enabled Meta to experience explosive growth both before and after its IPO in 2012. Previously, Ondrejka served as CTO of SmartNews, where he led global engineering teams and drove the adoption of artificial intelligence and large language model technologies to improve content discovery, ranking, and system reliability at scale. Earlier, he was the co-creator and CTO of Second Life, the pioneering virtual world developed at Linden Lab and named one of Time magazine's "Best Inventions" of 2002, which helped shape early thinking around shared digital spaces and online communities.
