ThePhish VS Cortex

Here is the repo: https://github.com/emalderson/ThePhish

I am curious to start on a cybersecurity project just for fun and to learn more about email analysis. Because at work, we usually do this manually for potential phishing mails like checking the headers, URLs, email content, etc, I was wondering if there is already any existing Github projects/softwares out there to automate this. If none, how feasible is this or what would I have to know prior to deep diving into developing such a tool. I am not asking for source code or anything, just wanna dabble in some blue team projects. I found one here - https://github.com/emalderson/ThePhish but this seems to be quite hardcore and linked to SIEM. I would want like to be able to just check one email at a time.

TheHive Cortex might come in handy here:https://github.com/TheHive-Project/Cortex

TheHive is a scalable 4-in-1 open source and free security incident response platform designed to make life easier for SOCs, CSIRTs, CERTs, and any information security practitioner dealing with security incidents that need to be investigated and acted upon swiftly. Thanks to Cortex, our powerful free and open-source analysis engine, you can analyze (and triage) observables at scale using more than 100 analyzers.

Basically, I am looking for something a bit like Cortex (screenshot), but for a generic and standalone use.

Thanks for the correction! You linked to the right Cortex, not to be confused with https://github.com/TheHive-Project/Cortex, haha. https://github.com/cortexproject/cortex is what we talk about. Naming is hard.
