How does command intent survive the loss of a primary AOC — and transfer with confidence to a continuity AOC? On 6 October, our own Director of Solutions – Federal David H., joins the team at UNCOMN (Joseph Monaco, Royce Lippert, and Connor Barnsley) for an interactive exploration of what the future AOC weapon system must get right. Attendees will explore how mission‑integrated collaboration with Narrow AI helps operators reconcile conflicting sources at the speed of execution — and what it takes for a continuity AOC to inherit authority with confidence. 📍 Lexington, MA 🗓️ 6 October 2026 ⏰ 0830–1230 📌 Register: uncomn.com/events/command-an… #DefenseTech #C2 #MOSA #ZeroTrust #MissionContinuity #AOC #DDIL #Mattermost

Good conversations lead to better outcomes. We caught up with @infodas at AFCEA International TechNet Europe last week, and the discussion around cross-domain information sharing between security domains was exactly the kind we show up for. There's real momentum building around how Mattermost and complementary technologies can work together to support secure, resilient operations across national security environments. More on that soon. Thanks to Fulvio Arreghini, Jason Blais, and Bill Marcus for the time. We're looking forward to what comes next. #AFCEATechNet #TechNetEurope #DefenceTechnology #SecureCollaboration #DigitalSovereignty #MissionCritical #CrossDomain #NationalSecurity #Mattermost

🏥 Today is World Patient Safety Day, a reminder that safe healthcare depends on clear, fast communication. When care teams are siloed, critical information gets lost. Mattermost keeps frontline staff, administrators, and IT connected in one secure platform, so the right people get the right information at the right time. Because in healthcare, communication isn't just about efficiency. It's about lives. #WorldPatientSafetyDay #PatientSafety #HealthcareIT #Mattermost

Zero Trust identity doesn’t break because of a missing control — it breaks because static roles freeze your access model in time. Part 2 of our series digs into why RBAC sprawl is one of the most common post‑incident findings, and how dynamic, attribute‑based access control (ABAC) closes the gap automatically. If access doesn’t reflect current reality, it isn’t Zero Trust. If you’re moving from Foundation to Advanced maturity, this post is your roadmap. 🔗 Read the full breakdown: mattermost.com/blog/zero-tru… #ZeroTrust #ABAC #CyberSecurity #Mattermost #IdentitySecurity #ContinuousAuthorization #DataCentricSecurity
