Mobile network operators (MNOs) have been managing cyber risk for years. But the challenges presented by today’s 5G networks are unlike any that have gone before. The attack surface has expanded significantly thanks to the new ways in which these next-gen networks operate. And as well as being a target in their own right, MNOs are increasingly viewed by adversaries as a stepping stone to reach their enterprise customers. Against this backdrop, operators must not only mitigate the financial and reputational risks of suffering a serious security breach. They must also ensure security programs keep regulators and customers happy. The latter is critical if MNOs are to drive ARPU and increased service consumption. Doing so will require them to focus not only inwards – on the thier own service platforms – but to expand this security to the user plane, where threat actors increasingly congregate. It will demand a unified, natively integrated security operations (SecOps) offering designed for specific telco use cases.
