During major incidents, “war rooms” now live in collaboration platforms, not conference bridges. Outage timelines, decisions, and escalations all flow through channels. When that environment is unavailable or noisy, incident coordination itself becomes the single point of failure. If it matters, it’s not just chat. mattermost.com/wp-content/upl… #IncidentResponse #Resilience #OpsCenter #BusinessContinuity

Mattermost Launches Confluence Successor for Sovereign, On‑Prem Networks With Atlassian retiring all on‑prem Confluence options, defense, intelligence, and critical infrastructure teams face a critical knowledge‑management gap, especially on classified, air‑gapped, and sovereign networks. mattermost.com/newsroom/press… #SecureCollaboration #SovereignTech #OnPrem #DefenseTech #PublicSectorIT #CriticalInfrastructure

Energy markets move fast, and the teams who win are the ones who act on real‑time intelligence. That’s why Enelyst built a global energy community powered by Mattermost, unifying streaming intel, live briefings, and expert discussion into one secure, scalable platform. It’s a powerful story of how real‑time collaboration transforms decision‑making in high‑stakes markets. mattermost.com/customers/enel… #EnergyMarkets #Collaboration #Compliance #RealTimeData #CaseStudy

Organizations that self‑host LLMs or rely on alternative model providers gain data sovereignty — but often lose access to web‑grounded reasoning. Without the ability to search the internet for context, AI agents struggle with accuracy, freshness, and operational relevance. Mattermost now closes that gap. With Mattermost v11.5, we’re expanding sovereign AI capabilities through a new agentic web search tool that brings richer context without compromising control. The feature supports Brave Search and Google Custom Search, and gives organizations full authority over how search is executed — from custom API endpoints to result limits to domain denylists that block unwanted sources. mattermost.com/blog/mattermos… #SovereignAI #SecureCollaboration

In many enterprises, the first time leadership realizes chat is a system of record is when auditors or legal ask for transcripts as primary evidence, not side notes. At that moment, chat is no longer informal, it’s discoverable ESI that must withstand regulatory scrutiny, retention policies, and audit trails. If it matters, it’s not just chat. mattermost.com/wp-content/upl… #Governance #Compliance #RecordsManagement #RiskManagement

⏰ Only 24 hours left to register, don’t miss this. If you’re securing containerized environments, this webinar is essential. Application‑level SBOMs leave major blind spots in the OS layer, and under strict compliance mandates, that’s not acceptable. Join Eva Sarafianou (Mattermost) and Chadd Owen (@anchore ) as they reveal how Mattermost moved from manual CLI scanning to a centralized, automated container security framework built for high‑security and defense‑sector customers. If you operate in regulated or mission‑critical environments, this is the playbook. #ContainerSecurity #DevSecOps #SBOM #ZeroTrust
