Day 1 of the @Oracle Defence Tech Summit is underway — and the conversation is already clear: Modern defence and intelligence missions demand collaboration that is faster, more secure, and built for distributed, data‑driven operations. As @NATO, government, and industry leaders gather in Brussels today, Mattermost is highlighting how self‑hosted secure collaboration strengthens decision‑making across classified, hybrid, and coalition environments. From resilient real‑time coordination to interoperable workflows that support sovereign AI and strict data‑control requirements, mission‑critical teams are redefining what operational readiness looks like. If you’re on site today, we’d welcome the opportunity to connect and explore how modern collaboration can elevate your mission outcomes. oracle.com/uk/defense-int… #OracleDefenceTechSummit #DefenseTech #SecureCollaboration #MissionCritical #NATO

Operational AI in defence cannot live in isolation. It needs to work where mission teams already coordinate, decide, act, and learn. Mattermost and @whitedotspace are partnering to advance secure collaboration and sovereign AI capabilities across defence and national security environments. The partnership brings together Mattermost’s mission-critical collaboration platform and Whitespace’s Collective sovereign AI operating system to help connect information, decision-making, operational action, and organisational learning within trusted mission environments. mattermost.com/blog/mattermos… #Whitespace #Defence #NationalSecurity #OperationalAI #SecureCollaboration #SovereignAI

If you care about pushing capability to the field faster — without sacrificing control — this is your path. Enter the DevSecOps experience. See how secure, high‑velocity delivery really works. experience.mattermost.com #Mattermost #DevSecOps #SoftwareDelivery #MissionCritical #SecureCollaboration #DefenseTech #OperationalExcellence #MattermostExperience

Getting teams mission‑ready shouldn’t start with sidebar cleanup. With Default Channel Categories in Mattermost v11.8, admins can now pre‑organize workspaces so every new member lands in a structured, operationally aligned environment from the moment they join. No more hunting through uncategorized channels. No more manual setup slowing down onboarding. Admins define the starting structure. Teams shape it to fit the mission. Watch how Default Channel Categories streamline onboarding and accelerate operational readiness in our latest video. #SecureCollaboration #MissionCritical #EnterpriseSoftware #Productivity #TeamOps

Mattermost is gearing up for React Nexus 2026, and we’re bringing serious engineering firepower to Bengaluru. Mohammed Zubair A. will be on stage showcasing how Mattermost takes React performance beyond theory and into true enterprise‑scale reality. His session, Load Testing Real React Applications for Production Performance, dives into the browser‑level load‑testing framework our team built to simulate massive real‑user concurrency — the kind of testing where API‑only approaches fall apart and real bottlenecks finally surface. If you care about render speed, memory behavior, or how React apps hold up when the load gets real, this is the talk you’ll want front‑row for. #Mattermost #ReactNexus #ReactJS #PerformanceEngineering #LoadTesting #WebPerformance #Playwright #OpenSource

Mattermost Agents V2 now gives secure teams exactly what they’ve been missing: true multiplayer tool calling. Nick Misasi’s latest blog shows how initiators stay in full control of approvals and disclosure while the rest of the team keeps awareness without inheriting authority. Sensitive outputs stay contained, credentials follow the accountable actor, and automation only runs when explicitly allowed. It’s collaboration with control — built for real defensive cyber and intelligence operations. mattermost.com/blog/multiplay… #Mattermost #AgentsV2 #SecureCollaboration #CyberDefense #MissionCritical #AIOps #OperationalSecurity #ZeroTrust #MCP #MultiplayerToolCalling

Sensitive data doesn’t stay still — and neither do mobile devices. For teams operating in classified, sovereign, or high‑risk environments, that creates a real operational challenge. With Mobile Ephemeral Mode in Mattermost v11.8, organizations gain device‑level control over how long sensitive data lives on mobile — from brief network dropouts to full offline windows. It’s fine‑grained, mission‑aligned control for the environments where data discipline matters most. Watch how it works in our latest video. #CyberOps #ThreatResponse #MissionCritical #SecureCollaboration #DefenseTech #OperationalExcellence #MattermostExperience

We're gearing up for TriCyCIS 2026 next week, and this year’s gathering is set to be one of the most consequential yet. With Defence, Government, Industry, and Academia converging at Royal Holloway to assess progress on the Strategic Defence Review, the 2026 agenda zeroes in on integration, digital advantage, and the accelerating Plan for Change. New command leadership, shifting threat landscapes, and rising expectations for sovereign capability make this year’s conversations especially timely. If you’ll be there, connect with us. Let’s explore how Mattermost supports the teams working to keep Britain secure, agile, and mission‑ready at home and abroad. #TriCyCIS2026 #AFCEA #DefenceTech #CyberSecurity #SecureCollaboration #ZeroTrust #MissionCritical #OperationalResilience #SovereignTech #PublicSectorTech

Mission‑critical teams thrive when the stakes are highest — and so does the Mattermost‑backed No. 34. In an overtime showdown at the Navy 250, @LayneRiggs99 kept his undefeated street‑course streak alive, taking the Mattermost Ford F‑150 to Victory Lane at the first‑ever @NASCARSanDiego national series race on an active U.S. military base. Precision. Pressure. Execution. That’s how you win. The story was big enough to land in @SInow, spotlighting Riggs’ performance and the intensity of the final‑lap battle. @Team_FRM #Mattermost #NASCAR #TruckSeries #Motorsports #MissionCritical #HighPerformance #Teamwork #SportsIllustrated #Navy250 #FrontRowMotorsports

When sensitive data lands in the wrong place, the response needs to be fast, documented, and defensible. Mattermost v11.8 introduces automatic data spillage report generation, giving security and compliance teams a complete, audit‑ready record the moment an incident is confirmed. When a post is flagged, a reviewer validates the issue and adds their decision. Mattermost then compiles everything, the flagged content, attachments, responses, reviewer notes, and full audit trail, into a downloadable, chain‑of‑custody‑ready report. No manual write‑ups. No missing details. Just a clear, structured incident record every time. #Mattermost #MissionReady #SecureCollaboration #IncidentResponse #Compliance #CyberResilience #DefenseTech #EnterpriseAdvanced

It’s go time, San Diego. The Mattermost‑backed car is rolling out on Naval Base Coronado, making history on the first‑ever NASCAR course run on an active U.S. military base — and the longest track on the 2026 circuit. From the Ellyson Start/Finish Line to Carrier Corner and the Coronado Chicane, today’s 16‑turn, 3.4‑mile course is built for precision, power, and total focus. The engines are fired. The crowd is ready. Let’s race. #NASCAR #RaceTheBase #Mattermost #SanDiego #MissionReady #Coronado250

Team - One hour until race start — and before we roll into the action, here’s one more fact to fuel the excitement. Fun Fact: Only three drivers in history have earned seven Cup Series championships: - Richard Petty - Dale Earnhardt - Jimmie Johnson And today, we’ll see another standout: Shane van Gisbergen, who charged from 18th to 1st to win the 2023 Chicago Street Race in the rain — proving how mastery of speed, grip, and control defines a champion.

Team - Two hours until the green flag — time for a look under the hood. Fun Fact: NASCAR cars may resemble street vehicles, but they’re purpose‑built machines engineered for extreme performance: - 750+ horsepower V8 engines - Aerodynamic, reinforced chassis - HANS devices, roll cages, and SAFER barriers for safety - Slick tires (no tread) for maximum grip - And since 2022, a single center‑lock fastener replacing the traditional five‑lug wheel — transforming pit‑stop choreography

Team - Three hours to go — and today’s race isn’t just fast, it’s historic. Fun Fact: Naval Base Coronado is the Birthplace of Naval Aviation, home to: - 17 squadrons - Three aircraft carriers (including the USS Carl Vinson, docked for race weekend) - Four SEAL Teams - Over 36,000 personnel Many scenes from Top Gun and Top Gun: Maverick were filmed right here — including the iconic beach scenes and hangar sequences.

Team - Four hours until engines fire — and the logistics behind today’s race are just as impressive as the action on track. Fun Fact: @NASCAR haulers traveled 2,400+ miles from Pocono, Pennsylvania, to reach Coronado Island — one of the longest hauls of the 2026 season. That’s a cross‑country mission requiring coordination, timing, and precision — the same qualities mission‑critical teams rely on Mattermost for every day.

Team - We’re officially five hours out from the @NASCARSanDiego race on Coronado Island — the first NASCAR event ever held on an active U.S. military base. As proud sponsors of the Mattermost‑backed car, we’re counting down with some of the most fascinating race‑weekend facts. Fun Fact: At 3.4 miles, the San Diego street course is the longest track on the 2026 circuit — big enough to fit Talladega inside it. It’s also a 16‑turn course weaving through Naval Base Coronado, including: - Ellyson Start/Finish Line — honoring the Navy’s first aviator - Carrier Corner — positioned between two aircraft carrier berths - Coronado Chicane — a technical sequence testing precision - Runway Road — skirting the edge of Halsey Field’s runway This is racing with a mission‑ready backdrop.
