Mattermost

Mattermost and Second Front are hosting an easygoing after‑hours meetup just steps from the conference. Swing by for good food, an open bar, and conversations with people who actually get the national security and defense tech world. If you want a break from the expo floor and a chance to connect with smart folks across the community, this is it. 📍 The Water Street Tavern & Key West Patio Bar 102 Water St, Baltimore, MD 21202 📅 June 3 ⏰ 7:00 PM – 9:00 PM RSVP today! https://lnkd.in/gGdqJW6a #TechNetCyber #AFCEA #Mattermost #SecondFront #DefenseTech #NatSec #Cybersecurity #Community #Networking #MissionCritical

Digital sovereignty has climbed the stack for a decade, but Leigh Marshall Dow’s new piece shows the next frontier isn’t cloud or AI, it’s the collaboration platform. The place where incidents are coordinated, decisions are made, and AI‑assisted workflows run is now part of the sovereign control plane. Most strategies still stop at infrastructure, leaving a gap in the very layer where operational coordination actually happens. As AI accelerates and regulated environments tighten, the real question becomes: who governs the environment where consequential decisions are made? Leigh breaks down why collaboration systems must sit inside the same sovereign boundary as the rest of the operational stack, and why Gartner Security & Risk Management Summit 2026 is the room where this shift becomes impossible to ignore.

Mattermost and Arqit are partnering to deliver sovereign, post-quantum-secure operational collaboration for Defence Ministries, NATO Allies, and coalition partners worldwide. The partnership combines Mattermost’s secure, mission-critical collaboration and command-and-control surface with Arqit’s post-quantum cryptographic infrastructure to provide a two-layer zero-trust collaboration environment where access is both policy-governed and cryptographically assured at the device level. Together, Mattermost and Arqit are helping defence organisations strengthen secure collaboration across coalition environments, supporting device-level trust, post-quantum security foundations, and resilient operations across complex and contested environments. Access control alone is no longer enough. Secure collaboration in defence requires continuous verification of trust across users, devices, and environments, with cryptographic assurance at its core. Mattermost and Arqit will be showcasing this capability together across upcoming defence events, including AFCEA TechNet International (9-10 June), Infodas DCS (11 June), Eurosatory (15-19 June), and the OCI Defence Tech Summit (25 June).

We're heading to TechNet Cyber, and Bill Anderson, our Principal Product Manager, will be taking the stage with a message mission‑driven organizations can’t afford to overlook. The collaboration layer has become the AI risk hiding in plain sight.   As AI accelerates decision‑making and operational tempo, the real exposure isn’t just in models or data pipelines, it’s in the everyday conversations, handoffs, and cross‑team workflows that now shape mission outcomes. Bill will break down how collaboration platforms have become a prime target, how adversaries exploit them, and what leaders can do to reassert control with secure, governed, mission‑ready environments. If you’ll be at TechNet Cyber, add this session to your agenda, and stop by the Mattermost booth to continue the conversation with our team. #TechNetCyber #AFCEA #SecureCollaboration #AIGovernance #MissionCritical #Cybersecurity #DefenseTech #OpenSource #DigitalModernization

Attending Gartner Security & Risk Management Summit? As AI, distributed teams, and regulatory pressure reshape the threat landscape, security leaders are rethinking how collaboration, decision‑making, and incident response actually run in practice, and how sovereignty, resilience, and control must extend all the way to the communication layer. We’re here for those discussions, those architectures, and the leaders building what comes next. If you’re at Gartner SRM, come connect with us.

Today we're highlighting insights from our CEO, Ian Tien, as he breaks down what AI transformation really means for organizations operating in high‑stakes, security‑first environments. As AI reshapes how teams coordinate, decide, and execute, Ian underscores why secure, self‑hosted, and sovereign collaboration is becoming essential infrastructure for defense, government, and regulated industries. His perspective focuses on practical, mission‑aligned AI adoption, strengthening operational agility while maintaining full control over sensitive data. #AITransformation #SecureCollaboration #MissionCritical #SovereignAI #OpenSource #DefenseTech #GovTech #DigitalModernization #OperationalResilience

We're proud to spotlight Jason Blais, VP of Product and Program Management, as he takes the stage at TechNet International to explore how Intelligent Mission Environments are redefining secure operations for defense and public‑sector teams. Jason’s perspective—shaped by deep product strategy, open‑source leadership, and hands‑on mission execution—offers a forward‑looking view into the next era of secure collaboration, AI governance, and resilient, high‑velocity workflows. If you’re heading to TechNet International, make space on your agenda. This session is a powerful opportunity to connect with the Mattermost team and see how organizations are building secure, flexible, AI‑enabled mission environments that meet the demands of today’s most critical operations. #TechNetInternational #AFCEA #SecureCollaboration #MissionCritical #OpenSource #AIForDefense #PublicSectorTech #DigitalModernization #MissionEnvironments

Our VP of Product & NATO Alliances Jason Blais is joining the NATO Cooperative Cyber Defence Centre of Excellence (CCDCOE) CyCon 2026 agenda tomorrow as a speaker on the panel “Collective Cyber Resilience in Supply Chains.” Jason will unpack how mission‑critical teams can harden resilience across tightly connected supply chains, drawing on field‑tested insights from secure collaboration, air‑gapped operations, and AI‑supported mission workflows that power defense and national‑security environments. If you’re heading to CyCon, this conversation delivers a clear, operational view of how allied organizations can maintain continuity, trust, and readiness across every layer of the supply chain. #CyCon2026 #NATOCCDCOE #CyberResilience #SupplyChainSecurity #DefenseTech #SecureCollaboration #OperationalResilience

Most teams handle the response. Few have a governed war room where the response actually runs. Our latest post breaks down why improvised channels fall apart under incident pressure — and why Gartner’s CIRM category is pushing organizations to treat the war room as real operational infrastructure. A governed war room is activated, not created. Access is role‑based. Records are complete and defensible. And AI agents operate inside clear, pre‑defined guardrails. This is the direction Mattermost is building toward — especially for regulated, sovereign, and mission‑critical environments. If you’re heading to Gartner SRM 2026, bring your latest post‑incident review to Booth 303. We’ll sketch what a governed war room looks like for your environment. https://lnkd.in/gBFz-QmB #IncidentResponse #CIRM #CyberResilience
