Looks cool… but as an Obsidian user, i’m uncertain as to the depth of the differentiators. Open source sure, but obsidian has served me well and is lightning fast to open even with all core plug-ins enabled plus several community plug-ins. Nearly all of which are optional anyway.

Obsidian also has quite a moat in terms of third-party functionality enhancements with very feature rich examples like Xcalidraw.

They also offer an end to end encrypted synchronization service that works better than file based synchronization services like iCloud, and a publish service that also works well.

No casting of aspersions, but as a former fortune 500 decision-maker for enterprise software in the millions, I have a tendency to critically think about why X vs Y for my personal stack as well. Counterpoints welcome!

I am a former enterprise architect in the cybersecurity space as well as a former director of cybersecurity operations and now own a cybersecurity consultancy.

My best advice is to ignore the tools for now. Understand the concepts of cybersecurity across all domains you can - from endpoint protection to privileged access management.

You can pick up a lot of this during the prep for certifications like CompTIA’s or CISSP.

Then whatever you find yourself most passionate about, find an entry level job in that discipline and that can be a way of starting “real world” exposure to the rest.

I hope this helps in some way, and best of luck!
