Hello r/selfhosted community!

I’ve been investing time into a side project named BREACH :: HARBOR. It’s a self-hosted cybersecurity platform crafted to not just fend off threats but to anticipate them. Here’s a breakdown:

  1. Collector: (Python) It gathers threat data (in simple words a honeypot).
  2. Core API: (Python/Django and React) Acts as the central hub where data is processed and visualized.
  3. Defender: This is still in the early stages, and I haven’t released the repository yet. Its role is to use insights to enforce security policies, starting from iptables/nftables.

For more details and the current state, check out https://breachharbor.com - it’s a simple landing page leading to the GitHub repositories.

Currently, its primary functionality revolves around collecting attack data and visualizing it. I’m actively working on adding a notification system next to the Core API.

Finally it should be able to proactively block specific hosts which have a bad score in real time (e.g. a subnet from country X attacking the local network or a remote host in the infrastructure). The Defender should be able to automatically manage blocking rules on the machines it’s installed. I have already gathered attack data for hundreds of thousands of attacks, the Collector is on the wild internet for 2 months now.

I genuinely appreciate feedback on the overall concept, workflow, and any essential features you believe should be integrated. I’m also planning to expand its functionalities and, in the future, offer a global threat data service (CloudSync) as a way to monetize. Or hunt any funding to let me invest more time on it and push it a little bit to become more popular as a platform.

Your insights and suggestions will be invaluable! Keep in mind this is a solo side project and it’s on early stage development (it doesn’t have detailed documentation yet), so your patience and constructive criticism are much appreciated.

Thank you in advance!
