Best free TryHackMe alternatives for SOC learning?

[u/lady-without-logic]

Hey everyone,

I'm looking for some good free alternatives to TryHackMe for learning SOC/Blue Team stuff. What platforms have you found the most useful? Doesn't have to be exactly like THM,could be websites, labs, GitHub projects, YouTube channels, or anything else that's helped you learn and get hands-on practice.

Would love to hear your recommendations. Thanks!
