What are some vendor-specific certs you've obtained and what are your thoughts on it after achieving it?

I'm not asking what to get to further my career, etc. I've been in this industry for 4 yrs and I know it differs per person. I'm asking what role you are in and what certs you chose to get and your overall thoughts on that cert after taking the exam. I'm specifically more interested in the vendor-specific certs Like Azure, Spunk, CrowdStrike, Okta, IBM, Cisco, Zsaler, AWS, etc. Not mainstream stuff like CISSP, Security+, SANs, etc.
