September 2026 Product Releases

New Release

Transit - GreyMatter SIEM-Less

GreyMatter SIEM-Less lets you detect, search, investigate, hunt and report in GreyMatter without a SIEM. Transit normalizes and runs detections on your data as it arrives, then writes it to your own Amazon S3 storage, where a new Search area queries it directly and streams results as they are found. You can save and share searches, turn them into dashboards, run the same search inside Investigate and Hunt, and take response actions straight from the results.

Enhancement

Mobile App - AI-Suggested Playbooks and One-Tap Reversals

In the Mobile App, incident detail now shows AI-suggested playbooks chosen for that specific incident, and playbooks that can be reversed are marked in Playbook Activity with a linked reversal that runs in one tap. The playbook run form can also be minimized so you can keep working in the app while it runs.

Enhancement

Respond - AI-Suggested Playbooks on Incidents

Suggested Playbooks on an incident are now selected by AI based on that incident's context, with an explanation of why each one is recommended. Executed playbooks can also be reversed directly from Response Activity, as they can in the Mobile App.

Chat - Build Workflows from Chat

GreyMatter Chat can now build a workflow from a plain-language description, returning the trigger, nodes, branching and node settings already configured, or recommending an existing template when one fits. Chat can also edit workflows you already have and explain what a workflow does and how its recent runs behaved, and every result arrives as an unsaved draft so nothing takes effect until you save it.
