The site's author is an active contributor to the ChameleonUltra project. All of their personal projects are hosted open-source on GitHub and Codeberg, and all technical resources are available completely free of charge.
The domain is currently directly accessible from the Chinese internet. The site layout is clean with no intrusive ads, and it loads very quickly. However, the site only offers content in English, with no Chinese localization support.
This site is an excellent technical reference for hardware security enthusiasts, embedded security researchers, and RFID developers, and it is also great for open-source security project contributors to learn from. It is not suitable for users who are only looking for commercial security services.
Overall, as a niche personal technical site, Sec1.dk provides sufficiently professional content, and its open, open-source approach aligns perfectly with the sharing spirit of the security community. It is a high-quality source of non-commercial content for the hardware security field.
