About Mattermost
Access control keeps getting finer-grained for defense buyers, buried in a blog that mostly publishes essays.
Most of this feed is editorial aimed at defense, government, and critical-infrastructure audiences — air-gapped networking, Zero Trust gaps in collaboration tooling, sensitive-data translation, mobile data protection. The actual product news arrives as periodic version digests. The most recent, v11.9, adds channel-level ABAC policies, ranked attributes, and program masking, plus native Azure Blob Storage so files stay in the infrastructure a team already runs.
