I got a cold email from them, decided to check out their website - they are short on information and you have to set up a call with them before you can use their product.

I decided to dig a bit deeper - they don't have a LinkedIn presence, and searching for the name of the email sender "Ayush Pateria" who is the co-founder of Snazzy (YC W21). But there's no mention of RocketSDR on their page.

I also can't find RocketSDR on YC's website.
