Every capability in nano answers a question someone had to answer during an incident. If it can't trace back to a real need, it doesn't ship.
Most SIEMs are slow, expensive, and built for compliance checkboxes, not for the people who actually respond to incidents. nano is the opposite: fast, affordable, and designed by someone who's been on the other side of the screen.
Every design decision in nano comes from real-world experience, not market research.

Self-hosted plans deploy into your cloud. Your data never touches our infrastructure. The core engine is open source under AGPL-3.0, so you don't have to take our word for what it does, you can read the code.
When you're investigating an incident, every second counts. nano is built on Rust and ClickHouse because fast search isn't a luxury, it's a requirement.
AI should help analysts work faster, not replace their judgment. nano uses LLMs for triage, classification, and detection, always advisory, always under your control.

nano started as a side project born from frustration: every SIEM I used was either too slow, too expensive, or both. The idea was simple, build a fast, efficient SIEM using modern technology. Rust for the backend, ClickHouse for storage, AI for analyst augmentation. No legacy baggage, no per-GB pricing games. Just a tool that works the way security practitioners actually need it to.
