San Jose, California, February 27, 2019
Zscaler, Inc., the leader in cloud security, announced today the release of its semi-annual 2019 Cloud Security Insights Threat Report – An Analysis of SSL/TLS-based Threats, which examines encrypted traffic across the Zscaler™ cloud from July through December 2018. The report, compiled by the ZscalerTM ThreatLabZ research team, delves into a variety of attacks executed over SSL and blocked by Zscaler, including phishing attacks, botnets, browser exploitation, and malicious content.
As the use of SSL grows to the point where it’s the standard protocol, cybercriminals are increasingly using encryption to conceal and launch attacks. This has become possible because SSL certificates, which used to be difficult to obtain, are now readily available at no charge.
“With the ever-increasing concerns over data privacy, there has been a massive trend toward Internet properties having encryption by default. This is a great thing for privacy, but it presents a challenge to IT security. Decrypting, inspecting, and re-encrypting traffic is nontrivial, causing significant performance degradation on traditional security appliances, and most organizations are not equipped to inspect encrypted traffic at scale,” said Amit Sinha, Executive Vice President of Engineering and Cloud Operations, Chief Technology Officer, Zscaler. “With a high percentage of threats now delivered with SSL encryption, and over 80 percent of Internet traffic now encrypted, enterprises are blind to over half of malware sent to their employees. The ZscalerTM cloud platform enables “man-in-the-middle” SSL inspection at scale, so it can inspect SSL traffic without latency and capacity limitations and provide customers with protection against the growing number of threats attempting to hide behind encryption.”
During the study period, Zscaler blocked 1.7 billion threats hidden in SSL traffic, which translates to an average of 283 million advanced threats blocked per month.
Key Research Highlights:
As the world’s largest security platform built for the cloud, Zscaler processes, on average, more that 60 billion transactions per day. With nearly 80 percent of that traffic encrypted, the ZscalerTM cloud blocks an average of 9.5 million SSL-based advanced threats every day.
