I'm in IT, started as a Linux sysadmin, then moved to AWS cloud, and now I'm a DevOps engineer.

Everything I have published here over the past month is practical content from real client work. Not theory. Not recycled tutorials.
If any of it helped you, share it with one person who would benefit.
That is the only ask.

Step 5: Get ANY IT job, even if it's not "security" (Month 4-8)
> Helpdesk, sysadmin, NOC — doesn't matter which

> Security teams want people who've broken things in production first

Unlikely - You are looking at maybe 2 sysadmin level folks, one of whom is the manager, the other few are support type roles
Combine that with the fact SSO often costs extra and edtech is full of terrible vendors that don't even offer it... it sucks a lot :(
