Oh boy. You're going to hate to know what programming language is used for apache, nginx, postfix, postgres, MySQL/mariadb, redis, wireguard and the majority of network hardware.

Absolutely. And I'm not using Apache, nginx, or postfix as a result. I'm also using userspace Wireguard, written in Rust.

For services that can't be avoided, I try to limit their exposure. I run Postgres with strictly controlled network access. Same for Redis.
