# brew

**brew** (Homebrew) is a free and open-source software package management system that simplifies the installation of software on macOS.

In the context of URZ security configurations, it is used to install:
- [[unbound]] and `ldns` for DNSSEC validation.
- A version of **OpenSSH** that supports SSHFP, bypassing the limitations of the native macOS client.
