Cisco's report is based on its Security Intelligence Operations (SIO), which plays a critical role in evaluating threats, given the prevalence of its solutions and the breadth of its security intelligence, Dayal said.

SIO inspects about 16 billion web requests daily through the Cisco Cloud Web Security and 93 billion emails daily by Cisco's hosted email solution, he added.

Besides, SIO daily inspects 2 lakh IP addresses, 4 lakh malware samples, 33 million endpoint files and 28 million network connects, he said.

On cyber security threats this year, Dayal said: "The primary challenges are greater attack surface, proliferation and sophistication of the attack model and complexity of threats and fragmented solutions."
