About

NULL PACKET is an independent technology and cybersecurity publication focused on self-hosting, Linux, infrastructure, networking, privacy, and modern cyber operations.

We cover a mix of technical tutorials, cybersecurity news, homelab projects, infrastructure breakdowns, security practices, and offensive security research intended for educational and informational purposes.

As more services move behind closed ecosystems and increasingly centralized platforms, we believe there is still value in open source community, transparent tooling, and self-hosted infrastructure that people can actually learn from, build on, and operate themselves.

The publication itself runs on self-hosted infrastructure powered by open-source technologies, with a strong focus on lightweight, privacy-conscious, and reproducible systems. Many of the environments, configurations, walkthroughs, and deployments discussed throughout the site are tested within real-world homelab and containerized environments.

We operate as an independent publication rather than a traditional corporate media outlet. That independence allows us to prioritize technical depth, experimentation, and practical infrastructure knowledge over trend-chasing and recycled content.

Some workflows used in research, drafting, and analysis may involve automation and AI-assisted tooling. However, all published content is reviewed, edited, and curated to ensure technical relevance, readability, and accuracy.

Our goal is not to flood the internet with generic content.

The goal is to publish useful material that helps readers better understand the systems they rely on — whether that means deploying containers on a Raspberry Pi, hardening a public-facing server, understanding a new vulnerability, or exploring the broader world of self-hosted infrastructure and cybersecurity.
