Real quotes from Reddit comments that inspired this opportunity
- “incredible people still think ufw with docker is fine when the latter blatantly ignores inboud firewall rules :o)”
- “The strength of container isolation is kind of very weak in a default Docker install for a variety of reasons”
- “bots can get your domain from the HTTPS certificate transparency logs, then either query AAAA on your main domain or on any made-up random subdomain”
- “If you have a public AAAA record... or if a cert gets logged, scanners don't need to brute force the /64-they just read the public logs”
