![]() stealthWatch illuminates encrypted traffic by using enhanced network telemetry and threat intelligence combined with multi-layer machine learning to continually trained classifiers and detect malicious or benign activity. ![]() You don’t need to see all the details to know that this is harmless but this probably best to look into what’s going on there without decryption. So how do you light up these growing dark spots? Cisco’s encrypted traffic analytics (Cisco ETA) with stealthWatch think of these shadows. As decryption is costly slow and could potentially violate privacy policies this leaves large parts of a network in the dark. In fact, by 2019 over 70% of attacks use encryption for making the contents of that traffic largely invisible to threat inspection. Although, attackers are using encrypted traffic to hide malware inspection and detection. Encrypted traffic offers much greater data privacy and security to enterprises without large capex investments. Encrypted traffic is on the rise and that’s both good and bad news.
