End-to-end technology services built on transparency and security.
Infrastructure you
actually own.
Nextcloud for files. Matrix for chat. Keycloak for SSO. NixOS for servers. Apple Business for devices. We deploy and manage it all — you keep every config, every credential, every byte of data.
Threats don't sleep.
Neither do we.
Our Blue Team SOC runs 24/7 with open-source tools you can audit. Real-time detection, proactive hunting, and incident response — for organizations that take security seriously.
Skills that stick.
Not certificates that collect dust.
Hackathons, intensive trainings, and multi-week courses in cybersecurity and open-source. Everything we teach, we do. Everything you learn, you apply on Monday morning.
