Cisco Systems denies the report in the Indian journal The Print that it is working with the Indian government to build a firewall against VPNs in Kashmir. A company spokesperson said, “Cisco strongly supports free expression & open communication on the Internet….We do not customize our products in any way to enable censorship.”

Cisco was however exposed in a 2008 Wired report showing the company collaborated with the Chinese government to build the ‘Golden Shield’, also known as the Great Firewall of China, to enable censorship & surveillance by the Chinese government.
