Hello all.
1,5 year ago I took GCIH exam and passed it successfully with 87%.
Now, my employee is paying me for another cert, but issue here is that it denies paying for training/cert which is about
offensive side. I know it sounds weird but that is an issue

I wanted OSCP.
But because it denies to pay for
offensive training I come across an idea to choose SANS course which will be helpful for OSCP and my penetration testing career in general.
So,question is that: "which SANS course should I take from where I'll get much benefit,that will be helpful for OSCP?"
P.S GPEN can't be chosen is not included(it's offensive)
My ideas is following:
1)
SEC503: Intrusion Detection In-Depth
2)
SEC505: Securing Windows and PowerShell Automation
3)
SEC506: Securing Linux/Unix
