Awesome, congratulations!
I’ve heard good things about the AWS Security Specialty certificate too. I’ve done a course for it which was great, though I never bothered to take the certificate (I don’t feel the need for it). Have you considered it?
My take so far is that there isn’t really any great options to protect against prompt injections. Simon Wilson presents an idea here on his blog which could is a bit interesting. NVIDIA has open sourced a framework for this as well, but it’s not without problems. Otherwise I’ve mostly seen prompt injection firewall products but I wouldn’t trust them too much yet.
I think this post ended up in the wrong place, I suspect you meant to post it to https://infosec.pub/c/infosecpub
Well done, congratz!
