Domain Validation certificates dominate the Web with a 94.4% share as per a Netcraft report. Organization Validation certs have a 5.5% market share, while Extended Validation products 0.1%.

60% of all the traffic goes via sites with DV, 27% via sites with OV, and 13% via sites with EV.

5. 36.3% of Sites Have Inadequate Security

According to SSL Pulse, a global dashboard for monitoring the quality of SSL/TLS support over time across Alexa’s top 150,000 most popular websites, a worrying number of sites (36.3%) don’t follow the best security practices. Of 134,99 sites surveyed on December 12, 2023, 49,065 had inadequate security.

Whether it’s an incomplete certificate chain or weak ciphers, the alarming figure emphasized why a proper SSL configuration is critical.

6. 62.1% of Sites Support the Latest TLS 1.3 Protocol

TLS 1.3 brings new security features and a faster TLS handshake. Since its release in 2018, 62.1% of surveyed sites by SSL Labs have migrated to the latest version. 2.0% of sites still support the now-deprecated SSL protocol.

7. Over 90% of All Phishing Websites Use HTTPS

According to the Anti-Phishing Working Group (APWG), over 90% of the phishing sites use the padlock in 2023. The report concluded that phishing activity, as well as the use of HTTPS protocol, are on a continuous ride with almost all phishing websites employing a valid SSL certificate.

That’s a significant 40% increase from 2019. Free SSL certificates offer phishers an extremely easy way to look more credible.

8. 21% of Alexa’s Top 100,000 Sites Don’t use SSL

According to recent findings from an Internet Security Report conducted by WatchGuard, an alarming proportion of Alexa’s Top 100,000 ranked websites, approximately 21%, are still neglecting to implement HTTPS protocol.

A staggering 20,911 websites within this elite group transmit data in plain text, exposing sensitive information to potential vulnerabilities.

9. 35.4% of Unencrypted Traffic Originates from Mobile Devices

This noteworthy shift represents a remarkable departure from the previous year when mobile devices accounted for over 70% of the unencrypted traffic.

The current figures revealed by Google Transparency Report indicate a substantial improvement in mobile device security.

10. 9.1732631e50 Years Needed to Break the SSL Encryption

Here at SSL Dragon, we’ve crunched the numbers to prove beyond any doubt that breaking SSL encryption is beyond human capabilities. Unless you build a hypothetical super-computer that will require electricity from 30% of all nuclear plants, decoding the encrypted certificate is just a pipe dream.

11. 82.9% of the Websites Use a Valid SSL Certificate

82.9% of the websites use a valid SSL certificate in 2023, up from 18.5% five years ago. The report courtesy of W3Techs highlights the progress of HTTPS adoption over the years, among other things.

While percentage-wise, this number is pretty high, the remaining unencrypted 17.8% amount to millions of websites that are a potential security threat to users.

12. 93.2% of Chrome Browsing Time Is Spent Over Secure HTTPS Pages

According to the same Google Transparency Report, the average browsing time is higher than the percentage of loaded pages, indicating that users are more inclined to quickly exit a website upon discovering it lacks proper website security measures.

The disparities among platforms in terms of browsing time are relatively minimal. Chromecast and Mac’s users are at an impressive 98% and 97% respectively. Conversely, Linux users rank lowest at 86%, while both Android and Windows users hover around the 94% mark.


As you can see, our 12 stats about SSL certificates indeed tell a story. The Internet is becoming a safer place as a result of affordable certificates and steady HTTPS encryption. However, plenty of challenges remain, especially the way websites configure their SSL certificates.

With more and more services and companies migrating online, the SSL industry will continue to grow in the upcoming years.
