Release notes-Cydarm 26.6.0

Updates and release notes for Cydarm version 26.6.0

Cydarm version 26.6.0 is now generally available!

The major call out for this release is that we have expanded Cydarm’s AI security assistant capabilities. Analysts can now instantly extract intelligence and STIX threat graphs from complex advisory documents or generate plain-language explanations of technical logs right inside the case activity thread, using either the Claude or ChatGPT connectors.

Alongside these enhanced AI features, this release introduces a Tenable SC integration and delivers critical system architecture enhancements.

Enhancements and bug fixes 26.6.0

28 May 2026

New features

AI Threat Intelligence extraction and explainer

When you enable an AI EzyConnect module, you can now:

  • Instantly parse threat reports, advisories, or pasted text to generate quick summaries and structured STIX threat graphs of key indicators of compromise (IOCs) directly inside a case.
  • Click directly on any case timeline item such as log snippets, JSON payloads, or STIX objects to receive an instant, plain-language explanation posted as a reply without leaving your workspace.
Tenable integration

You can now connect Cydarm to on-premise Tenable Security Center (Tenable.SC) deployments to automatically ingest vulnerability findings as cases, expanding on our existing Tenable.IO integration capabilities.Enhancements

  • AI actions now display a clear, actionable error message when the underlying AI service is unavailable or misconfigured, instead of failing without explanation.

Bug fixes

  • Fixed an issue where a case could be saved with a read-only Access Control List (ACL), leaving the case frozen and preventing its status, severity, comments, or other fields from being updated afterwards.

  • Resolved an issue in Reports where the organization selector was missing its label for some report types, and where clicking Deselect all could leave organizations selected after switching report types.

  • Fixed an issue where the email-sending integration could crash and get stuck in an endless restart loop when the configured SMTP server was unreachable or misconfigured.

  • Fixed an issue where creating a Tenable connector through the UI would fail with a confusing validation error.

  • Consolidated dependencies from both the API and UI, to provide a faster and more secure experience.
