Filigran Tech Stack

Open-source threat intelligence and attack simulation platform

Computer and Network Security New York 201–500 employees Founded 2022 Privately Held

Filigran builds an open-source threat management suite (OpenCTI, OpenAEV, OpenGRC) deployed across 6,000+ organizations. The stack is polyglot—Python, Node.js, TypeScript, React, GraphQL, Elasticsearch—with heavy cloud infrastructure (AWS, Azure, GCP, Kubernetes). Hiring accelerates across engineering and marketing, but pain points cluster around data ingestion scaling and cross-platform integration complexity, suggesting the product is straining under adoption growth and architectural fragmentation.
