 The file is a sample of large organizations that use Let's Encrypt. It is not a ranking, and it is not the 5,000 largest or most popular organizations in the world.
 It is intended for technology research, cybersecurity analysis, technographic research, competitive intelligence, market analysis and data science.
 Full Let's Encrypt statistics, including the global heatmap, usage by country and by industry, and the top websites, are published at [StackScan](https://www.stackscan.com/technology/lets-encrypt).
