Actions Required

There are no actions required in this release.

Behavior Changes

Changes that affect the way users interact with the product or interpret results are listed below.

  • AELDEV-67525: API error responses return the request identifier under a new name – The API error responses to return the request_id field in place of requestId were updated. After upgrading to 7.0.0, integrations and scripts that parse the requestId field in server error responses no longer find it and might fail or lose log correlation. Update any integration that reads the error identifier to use the request_id field.

  • AELDEV-67820: Public API endpoints for sensors now require RBAC privileges – Role-based access control (RBAC) privilege enforcement was added to the public sensor endpoints under /data_sensors, which were previously reachable by any authenticated API user regardless of privilege profile. After upgrading to 7.0.0, an API user whose privilege profile does not grant the privilege that governs the equivalent action in the user interface receives a 403 response where the request previously succeeded. Review the privilege profiles assigned to API users and automation that call these endpoints before upgrading. Enforcement on the pre-existing endpoints can be disabled for an organization as a transition measure; the privilege check on the new uninstall endpoint is always enforced.

  • AELDEV-28743: The tenant group list API no longer returns logo image data – The tgrp_logo field was removed from tenant group list API responses. After upgrading to 7.0.0, integrations that read the logo image from the list response no longer receive the image data. Update these integrations to retrieve logo images on demand through the /tenant_group/{id}/logo endpoint.

Deprecated Features

The following features are deprecated.

Upcoming Deprecation: SentinelOne Deep Visibility API – The Deep Visibility content type in the SentinelOne connector will be migrated to the Deep Visibility (SDL) content type in 7.0.0 due to a SentinelOne API being deprecated. Refer to the following dates:

  • Standard SaaS: Feb 15, 2027

  • GovCloud: April 26, 2027

Make sure to migrate content types from Deep Visibility to Deep Visibility (SDL) before the API is deprecated.

Upcoming Deprecation: Trend Micro Cloud One v2.0 API – The Trend Micro Cloud One v2.0 API is being deprecated. If you previously used the Trend Micro Cloud One connector, you should now use the Trend Micro Vision One connector in 7.0.0 and the Endpoint Inventory content type, which is only supported in the v3.0 API. The Trend Micro Vision One v3.0 API covers what previously required two separate connectors: Trend Micro Vision One and Trend Micro Cloud One. The Endpoint Inventory content type replaces the Computers content type previously collected through the Trend Micro Cloud One connector.

Migration is available in 7.0.0 to customers who request it.

Early Access Program

If you're interested in testing out new features ahead of general availability, consider joining the Early Access Program (EAP) by contacting your Stellar Cyber Customer Success representative and telling them which EAP feature you want to test. Once you've agreed to the EAP terms and signed up, the EAP feature is unlocked for you.

The purpose of this program is to boost performance and reliability through real-world customer insights, giving you a hands-on role in shaping a Stellar Cyber feature. In return, you'll receive early access to upcoming releases and the chance to guide product development.

The following EAP features are in this release:

Alert Auto Triage and AI Assistance

Alert Auto Triage automatically investigates the alerts in a case, runs Verdict Signal Checks against them, and assigns each alert a verdict with the reasoning behind it. AI Assistance is a natural-language investigation workbench built into every triaged case, converting your plain-language questions into answers grounded in the case data, alert details, and Verdict Signal Check (VSC) context that Auto Triage has gathered. Where the verdict tells you what Stellar Cyber concluded, AI Assistance explains why, and it supports follow-up questions in your own words with no query syntax to learn. AI Assistance is included with every Auto Triage license at no additional cost.

Case Summary and Analysis

Case Summary and Analysis uses AI to turn the evidence in a case into a readable account of what happened: an overview of the activity, its potential impact, the key insights drawn from the alerts, and recommended next steps. You can grasp the shape of a case without reading every alert first, and the summary gives a consistent starting point for triage, escalation, and handoff between shifts.

Exportable Dashboards — Report Integration

Exportable Dashboards lets you schedule dashboards created with the Dashboard Builder as recurring PDF reports. The schedule form includes a new Default PDF type that renders the dashboard as it appears in the Dashboard Builder, along with options to control table row counts, chart color palettes, and optional CSV exports. This capability lets you generate consistent, configurable reports from new dashboards while preserving the settings and PDF types used by existing scheduled reports.

XDR Connector Webhook Ingestion

This is a webhook framework that lets you post JSON data directly from any external system into Stellar Cyber, accelerating custom integrations and expanding your visibility across the entire security stack.

Customizable Case Correlation Strategies

This EAP feature introduces support for multiple case correlation strategies, allowing teams to evaluate and experiment with different approaches to grouping alerts into cases. Each strategy provides a distinct investigative perspective:

  • Attacker-Centric Correlation groups alerts by the source (attacker) host, making it easier to track adversary behavior across multiple targets.

  • Victim-Centric Correlation organizes alerts by the destination (victim) host, enabling focused protection and visibility on high-value assets.

  • Multi-Entity Correlation links alerts across interconnected hosts and actions to form a single case, offering a holistic view of extended or lateral attack campaigns.

This flexibility enables security teams to tailor investigations based on their operational priorities—whether that’s identifying persistently targeted endpoints, tracing threat actor movements, or capturing full-scale intrusion campaigns.

Alert for Suspicious OCI Tenant-to-Tenant Communication

This EAP feature introduces a new alert type that detects cross-tenancy communications in the Oracle Cloud Infrastructure (OCI). By analyzing tenantId fields in audit logs, the feature identifies requests that target resources in a different tenancy. This provides accurate visibility into potentially unauthorized cross-tenancy activity and strengthens oversight in OCI environments.

To join the Early Access Program and begin testing these features, contact your Stellar Cyber Customer Success representative.

Resolved Issues

The following issues were resolved in this release.

Stellar Cyber Platform System Requirements

You must install the Stellar Cyber Platform in an environment that meets or exceeds minimum system requirements. Refer to the following sections for the minimum system requirements for different target environments:

System Requirements for Cluster Installation in VMware ESXi

You can install the Stellar Cyber platform on a dedicated ESXi server running VMware ESXi 8.0, 7.0 or 6.7. The target ESXi server must have sufficient resources to support separate virtual machines for the cluster nodes required by your expected daily ingestion volume.

Refer to Stellar Cyber Platform (DP) System Requirements and Capacity Planning for details on the quantities of cluster nodes required for different daily ingestion volumes, as well as the system resources you must provision for their virtual machines.

Keep in mind the following:

  • Each VM  must be thick-provisioned.

  • You can install all of the VMs in the same datastore if there is sufficient space for both the VMs and the disk space required for the Data Lake's ElasticSearch data. However, Stellar Cyber recommends that the Data Lake uses a dedicated datastore.

Stellar Cyber supports SSD disks for both the OS and Data Lake drives (SATA, SAS, or NVMe). HDD disks introduce latency and are not supported.

Scaling Up Performance with a DP Cluster

You can configure up to ten DP servers to operate in a cluster to achieve improved Stellar Cyber performance. Stellar Cyber cluster testing indicates the following performance guidelines when adding additional DPs to a cluster:

  • With data replication disabled, the aggregated ingestion throughput grows linearly with the number of DP servers.

  • With data replication enabled (the default), the aggregated ingestion throughput is about 30% lower than the throughput without data replication.

Upgrading the Stellar Cyber Platform

You can upgrade the Stellar Cyber Platform from 6.5.0 or later to 7.0.0. You must:

  • Prepare for the upgrade

  • Upgrade the Stellar Cyber Platform to 7.0.0

  • Upgrade the sensors

  • Verify the upgrade

For more detailed instructions, refer to Upgrading Software.

Due to additional functionality and features, resource utilization (CPU and memory) might increase depending on your usage patterns. You can keep tabs on the platform's CPU and disk usage by clicking the Node List button in the System | Data Management | Data Analyzer page. If necessary, you can scale up your platform by adding DA and DL worker nodes, as described here for AWS, GCP, and OCI.

Important Note for Air-Gapped Environments: The 7.0.0 release requires connectivity to specific external URLs to enable components included in the installation image, such as Early Access Program functionality and various features and fixes. In air-gapped or dark site environments, where externasl network access is restricted, these components cannot be enabled after installation. Before upgrading to 7.0.0, confirm that the required connectivity to these URLs is available.

Prepare for the Upgrade

To prepare for the upgrade:

  • Back up the data and configuration
  • Make sure the sensors are up and running
  • Take note of the ingestion rate
  • Take note of the number of alerts
  • Make sure the system health indicator shows
  • Run the pre-upgrade check

Upgrade the Stellar Cyber Platform to 7.0.0

To upgrade the Stellar Cyber Platform to 7.0.0 from a version earlier than 6.5.0, first upgrade to 6.5.0.
  1. Select Settings | ORGANIZATION MANAGEMENT | Software Upgrade.

  2. Choose 7.0.0.

  3. Select START UPGRADE.

Upgrade the Sensors

About Sensor Release Timing

Sensor upgrade packages release a few weeks after the corresponding DP release. Staggering the releases helps Stellar Cyber confirm whether any issues found after a DP upgrade come from the DP or the sensor and fix critical bugs before the new sensor is released.

If a sensor upgrade link in the docs doesn't resolve yet, the package simply isn't available yet — check back in a few weeks!

CentOS 7.1 Prerequisite – Update curl to 7.29.0-59.el7_9.2 or Higher

Before upgrading any Linux Server Sensors running in CentOS 7.1, you must check your curl version and update it to 7.29.0-59.el7_9.2 or higher to use the strong encryption required by the Stellar Cyber Platform.

  1. Check your curl version as shown below:

    yum list installed curl

    \* Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile Installed Packages curl.x86_64 7.29.0-19.el7

  2. If the listed version is lower than 7.29.0-59.el7_9.2 (as it is in the example above), use the following commands to update the curl package:

    yum makecache

    yum install curl

  3. If installation of the curl package fails, it is most likely because CentOS is trying to use a repo that has reached its end of life. Try updating the base URL and then reinstall curl. The following sed command makes the necessary changes for most environments to ensure that the updated curl package can be installed:

    sudo sed -i.bak -e 's|^mirrorlist=|#mirrorlist=|' -e 's|^#baseurl=http://mirror.centos.org/centos/\$releasever|baseurl=http://archive.kernel.org/centos-vault/7.9.2009|' /etc/yum.repos.d/CentOS-Base.repo

To upgrade sensors:

Depending on the type of server sensor, upgrade your sensors to version 6.6.0 as follows:

  • Linux Server Sensors: Upgrade directly to 6.6.0 from either of the two previous releases: 6.4.0 or 6.5.0.

  • Windows Server Sensors: Upgrade directly to 6.6.0 from an extended range of previous releases: 5.1.0 through 6.5.0.

    If you are upgrading a Windows Server Sensor, complete any pending updates for the host Windows machine before upgrading the sensor.

  1. Select System | DATA SOURCE MANAGEMENT | Sensors | Sensors.

    The Sensor List appears.

  2. Select Manage | Software Upgrade.

    The Sensor Software Upgrade page appears.

  3. Choose the target software version.

  4. Choose the target sensors.

  5. Select Submit.

Verify the Upgrade

To verify that the upgrade was successful:

  • Check the Current Software Version on the System | ORGANIZATION MANAGEMENT | Software Upgrade page.
  • Make sure the sensors are up and running.
  • Check the ingestion rate and make sure it is as expected.
  • Check the number of alerts and make sure it is as expected.
  • Check the system health indicator:
    • indicates a perfectly healthy system.
    • indicates minor issues. Monitor the system for 30 minutes. If the issues remain, investigate further.
    • indicates major issues. Contact Technical Support.

New features, updated ML algorithms, and enhanced configurations may change ingestion and detection patterns. We recommend the following to ensure a smooth upgrade:

  • Upgrade sensors with the Sandbox and IDS features enabled before sensors with the only the Network Traffic feature enabled. Sensors with Network Traffic enabled send data to sensors with Sandbox and IDS enabled for additional processing.
  • Upgrade sensors in batches instead of all at once.
  • For server sensors (agents):
    • Upgrade a small set of sensors that cover non-critical assets.
    • After 24 hours, ensure that your ingestion is as expected, then upgrade a larger set.
    • After 24 hours, ensure that your ingestion is as expected, then upgrade the remaining server sensors.
