Mostly continuation of established trends. The number of TLS enabled websites has rebound since last month, going back above 50% level, but still below the May watermark. Detailed analysis on my blog: https://securitypitfalls.wordpress.com/2015/07/29/july-2015-scan-results/ SSL/TLS survey of 501992 websites from Alexa's top 1 million Stats only from connections that did provide valid certificates (or anonymous DH from servers that do also have valid certificate installed) Supported Ciphers Count Percent -------------------------+---------+------- 3DES 424054
