04 — ABOUT SECURITYOPS

Built by someone
who runs it.

Cristian Cezar Moisés
Creator & maintainer · Caxias do Sul, Brazil

SecurityOps brings together free software, self-hosted infrastructure and practical security education. Cristian is an IT analyst and developer working with C, Rust, Python and Scheme, with a technical background in information security.

The work connects GNU Guix, encrypted backups, secure transport, privacy tools and services operated on its own infrastructure. Here, the code and the systems become learning material: understand the choices, read the documentation and practice in authorized environments.
