The Web Almanac is a collaborative report that provides valuable insights into how people build and use the web. It's created by a community of experts who analyze data from millions of websites, sourced from HTTP Archive's periodic web crawls. The last edition included 43.88 TB of data from 8.36 million websites. Security teams can benefit from this report by discovering new features and conducting gap analysis to identify common areas where websites fall short in security best practices. Participation in the Web Almanac project is open on GitHub, allowing developers, operations, and security practitioners to contribute their expertise.
