Millicom and its affiliated entities (“Millicom”), takes protecting our networks and customers as one of our highest priorities. Millicom has a dedicated Global Chief Information Security Officer (“Global CISO”) whose team oversees the strategy and direction of all security-related actives across Millicom. . Millicom’s global information security program provides policies and standards, vulnerability management, third-party risk management, and oversees the implementation of technical solutions across Millicom. The Global CISO regularly reports on new and evolving risks and technology initiatives to the Millicom Board of Directors. Additionally, general progress of the security program is highlighted in Millicom’s annual report to investors, which can be found here.
Since Millicom operates in many countries around the world, developing a risk framework that can address the various legal and regulatory reporting needs, as well as the unique challenges individual countries face, is paramount. Millicom has implemented a risk framework which is based on a combination of the NIST Cybersecurity Framework (CSF) as well as the ISO/IEC 27001:2013. This blended approach allows each individual country to address local regulators in whichever format they prefer, while providing a common risk and maturity measurement across our entire enterprise.
