2012年6月份，MarketandMarket公司发布了一份市场分析报告（“Cyber-Security Market - Global Forecast & Trends (2012 – 2017) (Identity & Access Management, Risk & Compliance Management, Data Encryption, Data Leakage Prevention Solution, Data Recovery Solutions, UTM, Anti-Virus, IPS/IDS, Web Filtering, Fire-Wall, Vulnerability Management) Advanced Technologies, Geographical Analysis & Competitive Landscape”），称到2017年，全球的cbyersecurity市场将达到1200亿美元的规模，而在2011年市场价值已经有637亿美元。

这份报告中的cbyersecurity市场的定义是：Cyber security is an executive level about information security in the electronic/digital era, and a recommended structure to address the threats and vulnerabilities present at each of the layers that make up a communication infrastructure and distinctive information. Cyber Security includes the development of security types, services, and technology & solutions, which can also lead to offensive applications. These applications are basically designed for defense & aerospace use, and are often also referred to as cyber defense or cyber weapons. Cyber security is not only used in the IT domain (primarily internet protocol or internet connected devices), but also industrial equipment and telecoms equipment.

根据报告，Cyber Security market in 2011 was worth $63.7 billion, and is expected to grow to about $120.1 billion by 2017. It is expected to have a healthy CAGR of 11.3% from 2012 to 2017. North America, Western Europe, and APAC regions are emerging market, whereas Latin America, Middle East & Africa, and Eastern Europe regions are considered as high growth markets. In 2011, North America accounted for about 40.1% of the global revenue, and is expected to grow at a CAGR of 9.2% from 2012 to 2017. Western Europe and APAC are estimated to contribute $28.1 billion and $25.9 billion, respectively, by 2017; at a CAGR of 10.1% and 13.4%, from 2012 to 2017.

报告显示，美国是2011年网络空间安全市场的最大头，北美占据了637亿美元的40%，并且，只仅在美国市场呈现出来政府市场份额约等于私有部门份额的情况，而其他市场上一般都不是政府主导。可见美国政府对于网络空间安全的投入之大。不过，我觉得在中国政府主导的市场规模也不小啊。

报告还给出了一个网络空间安全的演进图：
