Fl0wer
The Network Intelligence solution for the rest of us.
Fl0wer is a lightweight, high-performance Network Intelligence & Telemetry Analytics engine backed by ClickHouse. It ingests NetFlow, IPFIX, sFlow, and East-West Kubernetes traffic to deliver sub-second queries over massive flow datasets. With real-time threat detection (MISP/blacklists) and automated compliance reporting (NIS2, DORA, ISO 27001), it ships as a ready-to-use ISO for rapid 30-minute deployment.
After more than a decade leading NOC teams at a Managed Service Provider and writing a book on network flow traffic analysis (Mastering Network Flow Traffic Analysis), I kept running into the exact same frustration:
Traditional enterprise telemetry tools (NetScout, Kentik, SolarWinds) are insanely expensive and charge heavily based on data volume or EPS. On the flip side, open-source DIY stacks (ELK, Grafana) require months of engineering, constant maintenance, and high resource overhead just to query simple flow records.
I built Fl0wer to bridge that gap—a lightweight, high-performance Network Intelligence & Telemetry Analytics platform engineered for real-world operations, hybrid networks, and MSP workflows.
Key Technical Highlights:
ClickHouse Core: Runs natively on Debian 12 with a ClickHouse columnar database, providing sub-second queries over billions of flow records with minimal hardware footprint.
Multi-Source Ingestion: Ingests NetFlow (v1/v5/v9), IPFIX, sFlow, plus lightweight Go agents for granular East-West traffic visibility across VMs and Kubernetes workloads.
Real-Time Threat Hunting: Instant reloading of IP and domain blacklists with live MISP integration for active threat detection.
Automated Compliance: Generates executive and technical PDF reports mapped directly to NIS2, DORA, GDPR, and ISO 27001 frameworks.
Turn-Key ISO: Ships as a full ISO image—you can have a fully functional node running in about 30 minutes.
Whether you're managing complex internal infrastructure or delivering managed security services to clients, Fl0wer is built to give you deep traffic visibility without the bloat or unpredictable pricing.

Who hunted Fl0wer?
Fl0wer was hunted by Gilberto Persico. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
