In the first half of 2017, 60 percent of transactions have been over SSL/TLS, Zscaler researchers said. Malicious content being delivered over SSL has more than doubled in the past six months.

The number of payloads being sent over encrypted connections doubled in first six months of 2017 compared to all of 2016.
