“5G networks are beginning to touch every facet of human life - from work, entertainment, personal and social activities, making security central to this monumental technology. Mobile Network operators and their vendor partners have always and will continue to put security as a top priority for their networks.”

Chris Pearson, President, 5G Americas

“Security has been designed and incorporated into 5G standards. A strategic approach is taken related to cloud-native services, open-source software, APIs, SDN, and NFV, which together provide greater overall 5G network security.”
