A statement from the Iraqi Telecommunications Ministry said: "Internet gateway is a fundamental pillar in ensuring a country's data security. Nokia and Al-Awsat are the right partners helping us achieve this in Iraq.
"Nokia's solution meets the security requirements of public sector and mission-critical applications, thereby enabling us to secure the network with high-capacity and high-performance protection."
