About Security Ops

Security Ops is a comprehensive, independent initiative dedicated to advancing cybersecurity through open-source solutions, hardened configurations, practical tools, and educational resources.

Created by Cristian Cezar Moisés, a cybersecurity enthusiast and developer from Caxias do Sul, Brazil, the project emphasizes privacy, minimalism, reproducibility, and long-term sustainability. Services and tools prioritize reduced attack surfaces, strong cryptography, server-side processing, and full compatibility with JavaScript-disabled environments.

The ecosystem promotes user sovereignty, open-source principles (with ongoing migration to Codeberg), and practical education to help users regain control over their digital lives.

Online Services

Privacy-focused, decentralized online services built with security, performance, and minimal third-party dependencies in mind. All services are self-hosted and designed for maximum user control.
