Deng Jiewei, from Guangdong, was charged with illegally selling programs known as virtual private networks (VPNs), according to court papers.
VPNs are illegal in China because they let people avoid government monitoring of what they are doing.
The sentence is part of a larger crackdown on the use of VPNs in China.

Deng started selling VPNs in late 2015 and was arrested in August 2016 for selling software which lets users “visit foreign websites that could not be accessed by a mainland IP address”, reported the South China Morning Post.
Many people in China have used VPNs to skirt the restrictions and visit blocked sites.
A VPN securely directs browsing traffic to off-shore servers so people can browse the web unimpeded.
In January 2017, the Chinese government kicked off a campaign to stop people using VPNs. This meant many commercial VPN suppliers were shut down and many of those making money from selling the software for VPNs were warned that they faced being arrested or fined.
The government crackdown also led Apple to remove 60 apps from its Chinese app store that let people browse the web via a VPN. The firm was heavily criticised for its decision.
In August, five websites including shopping giant Alibaba, were told to remove listings that offered people access to VPNs.
Multinational firms operating inside China were still allowed to keep using VPNs for staff accessing corporate resources.
