Feb 1, 2026February 2026: Stabilized Azure SDK integration in cartography by fixing import path and adding a version constraint to prevent future breaking changes. This reduces runtime failures and improves maintainability for downstream users relying on Azure resources. Key actions included aligning imports to azure.mgmt.resource.subscriptions for SubscriptionClient and introducing an upper bound on azure-mgmt-resource (<25.0.0) to guard against breaking changes in major version upgrades. The changes were validated with import-path tests and lint checks, contributing to higher reliability and smoother downstream usage. This work lays groundwork for continued Azure SDK compatibility as dependencies evolve.

Oct 1, 2025October 2025 (Month: 2025-10) — Repository: cartography-cncf/cartography Overview: Delivered security-focused enhancements, data-model improvements, and reliability upgrades that increase the business value of Cartography graphs. The work strengthens IAM policy decision logic, enriches threat modeling with MITRE ATT&CK integration, enables precise first-launch correlation for EC2 resources, and lays groundwork for GSuite federation and improved dependency hygiene. Documentation improvements clarify CAN_ASSUME_IDENTITY relationships across AWS/Okta, and CI reliability was enhanced through retry logic for GitHub team synchronization. Business impact: sharper, faster security queries; richer and more actionable security context in the graph; improved incident response capabilities; more resilient data pipelines and integrations across providers; and clearer federation semantics for multi-provider environments.

Apr 1, 2025April 2025 -- Key deliverables across identity integration, cloud ingestion, and data modeling, with a focus on business value and reliability. Microsoft Entra ID Integration was introduced to enable tenant and user data ingestion and CLI authentication via environment variables, laying the foundation for secure, scalable access control. AWS data ingestion received substantial enhancements, adding EC2 route table support, route ingestion, classic Load Balancers/listeners, VPC/IGW integration, and region-based syncing control, complemented by integration tests for VPC and IGW and a region filter (--aws-regions) to limit data pull to selected regions. The CrowdStrike host data model was refactored for consistency, updating ingestion logic, indexes, and Python data models to improve data quality and query performance. Documentation was refreshed for getting started and intel usage, and the theme was updated to Shibuya for readability. Overall, the changes broaden data coverage, improve data quality, and streamline developer onboarding and security configuration, delivering tangible business value with more complete, reliable data and stronger security posture.

Mar 1, 2025In March 2025, delivered a major feature expansion for Cartography with one-to-many data model support, enriching the ingestion pipeline for AWS IAM Instance Profiles and introducing modules that link IAM instance profiles to AWS roles and EC2 instances. The data model refactor enables richer relationships and more accurate asset mapping, accompanied by updated tests and documentation to ensure reliability and ease of use. Addressed reliability and compatibility gaps by fixing Neo4j driver v5 integration: ensured consume() is not invoked on a closed transaction and updated tests to cover the newer driver version. Improved developer experience and external visibility through documentation improvements, including an AWS IAM API reference link and an updated Who Uses Cartography section that adds SubImage.io. Overall, these efforts increase data fidelity, reduce ingestion friction, and enhance maintainability, directly supporting better security posture, asset visibility, and operational decision-making for customers.
