Vodafone disclosed that it discovered security flaws in equipment supplied by Chinese hardware maker Huawei to its Italian company in 2011 and 2012. The world's second-largest mobile phone operator said it discovered security vulnerabilities in two products, although both incidents they were quickly resolved by the Chinese company. Huawei has come under increased surveillance, while the United States has asked its allies not to use its technology to the detriment of Chinese espionage. Last January, Vodafone suspended the deployment of the company's equipment on its core networks while it waited for Western governments to give the Chinese company full security clearance. The UK government is still deciding the role Huawei equipment will play in a future 5G network, but plans to announce its final decision next month. A government report released in March criticized the company for failing to address long-standing security issues. British security officials said they discovered "several hundred vulnerabilities and problems" with Huawei equipment in 2018.
