I can't really think of anything I'd really need, but I also don't want it to go to waste. Also there are so many good free resources available online.
Do you have suggestions on how to best spend it?
Ideas I had: - Books (I mainly read online blogs) - Hardware (I have a tablet for reading, a raspberry to deploy mini projects and testing devices) - Certifications (Don't really need them currently and not a big fan of the time constrained certs as I'd have to renew them) - Courses (There are a lot of good free courses I can do) - Access to platforms (e.g. Hack The Box, TryHackMe, ...) - Soft skills trainings
O'Reilly Learning[0] is amazing. (Of course, your employees would have to read the books...)

I don't know what your title means, do you work with apps or secure the infrastructure apps talk to? If your focus is strictly on software/code security disregard my advice (although since you mentioned tryhackme, my opinion might still be relevant)
MTREES.io
There is a free manual about product and systems design and a pay for test that humans take and come up with a product or a creative solution. Then share the results and crown the queen!
Can you mention any good courses which are free?
