I think the domain indicades something like keybase.

If they have a bug bounty programm, look at it.

Also try to contact the $company's domain Admin (who.is e.x. give it to you) or, if availabel, the Network Abuse Team for further help to get in contact.

I use LetsEncrypt and ggssl.com. Simple. Free/Cheap. Nice customer support.

So... I think because of this, I will buy a VR-Glass :3 <3

Mhhh DigitalOcean has a 5$ VPS with 512MB RAM and a 99.99% Uptime. (https://www.digitalocean.com/features/reliability/)

Also Scaleway with arroung 3€+VAT is fairly nice. With 200Mbit unlimited bandwidth and 2GB RAM + 4 ARM Cores.

I use Digital Ocean now, but was looking for something cheaper but almost as good.

Ohh to add this: I know HPKP works with Publickeys, the only question is, if I need to sign it first or can I sign it when I need it?

Ahh nice, thank you :-)

With my tor relays I pushed around 150Mbit up and Down. Which is around 45TB per direction and Month.
