Flit is a suite of open-source tools for security engineers and developers. Watch ingests and correlates your logs. Ghost maps and scores your non-human identities. Gauge scores your Zero Trust posture in minutes. All free. No cloud, no account.
Your logs. Your identities. Your Zero Trust posture. Flit gives you complete visibility into all three — locally, privately, and instantly.
A single static binary that turns your machine into a full-featured syslog receiver and SIEM. Ingest from any system, parse every format, build correlation rules, and get alerts — all in real time, with nothing sent to the cloud.
Non-human identities — service accounts, app registrations, managed identities — are your largest unmanaged attack surface. Ghost scans your Active Directory and Azure Entra ID, builds a complete inventory, and scores every identity for risk.
A free, instant Zero Trust readiness assessment that runs entirely in your browser. Answer 16 questions across 5 pillars, get a scored report, and download a prioritized remediation roadmap tailored to your environment.
Every Flit tool is designed around three principles. Not features — principles.
Your data never leaves your machine. No cloud ingestion, no telemetry, no SaaS accounts. Everything runs as a static binary with a local database. You own your data, full stop.
Every line of code is public, auditable, and MIT licensed. No black boxes, no hidden behaviour. Fork it, extend it, contribute to it. Security tooling should be transparent.
Download, run, done. No YAML files, no cloud credentials, no dependencies. Sensible defaults get you to your first insight in under 30 seconds on any platform.
No cloud. No account. No config. Download Watch or Ghost — or take the Gauge assessment free in your browser right now.
