Kumo is a project started in order to provide a free, open-sourced and reliable solution in DDoS mitigation.
While creating Kumo I was thinking about it as a better alternative to fail2ban software. fail2ban is great in blocking abusing users at a small scale but when there are thousands of requests per seconds it starts to struggle quite a lot with CPU spiking to 90%-98% and basically killing the server. Kumo in the same scenario can keep the CPU usage around 1%-5% and it has some nice bonus features like enabling Under Attack Mode in Cloudflare.
- .NET Core 2.1
- Cloudflare
- Linux server
- Nginx
- Lightweight & fast
- Supports both IPv4 and IPv6
- Mitigates both Layer7 (HTTP) DoS and DDoS attacks
- Enables Cloudflare Under Attack Mode when massive DDoS is detected (optional)

Please keep in mind that this is a very simplified example.
