January 2026 — Delivered the Attack Paths feature with Neo4j integration for visualizing attack paths from AWS scans, with new models, views, and API endpoints; stabilized the Neo4j driver and sessions, added lazy initialization and replica reads for findings, started Neo4j at API startup to reduce latency, and implemented startup/test optimizations. Improved data ingestion Cypher, cache-clearing post-scan to ensure fresh data, and fixed issues such as deleting None databases during scheduled scans. Performed security hardening via dependency upgrades (boto3/botocore, Slack SDK) and updated tests for regional clients/detectors. The work accelerates actionable security investigations, reduces maintenance burden, and improves data reliability for defenders.
