In less than five years, Let’s Encrypt has secured almost 200 million websites with free TLS certificates.
It wasn’t that long ago that most websites weren’t secured with Transport Layer Security (TLS) encryption. You could tell because the sites started with HTTP instead of HTTPS. Today, 81% of web pages use HTTPS globally, and 91% are secured in the US. For that vast increase in secure web browsing, we owe a large debt of gratitude to Internet Security Research Group (ISRG) with its Let’s Encrypt project. Let’s Encrypt has just issued its billionth web security certificate.
