Online security is always one of the biggest concerns among all internet users. No one wants to suffer the pain of computer hackers and information stealers. Thus, a VPN could be an important tool to protect our security due to its technical features. A capable VPN service, for example, iTop VPN, could protect your data security.

  • Security on Public Wi-Fi

If you are a businessman or global traveler, then you might need to frequently connect to unsecured public network/ Wi-Fi instead of a safe one. The reason why VPN is used is because a public Wi-Fi with zero cost will come at the expense of security. When you are replying to a crucial business contact with e-mail in a café or scrolling your SNS for spending leisure time at the international airport, your online activity & traffic could possibly be tracked & intercepted by someone.

If you have to connect to the public Wi-Fi pretty often, thus, a good VPN, even a free unlimited VPN features will give you decent security protection. A virtual private network will reroute your internet traffic from the public server to the VPN provider’s server. Meanwhile, your IP address will be masked at the same time. Hackers could find no way to track your traffic if you are connecting to a VPN private server in a public network.

  • Remote Work Security

One thing why VPN is used during remote working is the VPN will do to protect your data security. The VPN will encrypt your data when transmitting between your device & the VPN server. If you are working with a classified project and you need to keep it secret from others. Using a VPN is an effective way to protect it (since your data has been encrypted by the computer algorithm).


If you are working from home for some reason, the VPN could be extremely helpful. There will be no disclosure of confidentiality when you transmit encrypted data to the company. The hackers & potential competitors would stand no chance to know your business secret anymore. And that’s why VPN is used.

Do you have such an experience that after you search Google for “diaper” for some details, then you click on a YouTube video, and the YouTube advertisement immediately shows you some baby care products. Then you are scrolling the Amazon pages seeking something to buy, you’ll find that Baby Caring & Kids Toys category has been pushed to the top and bait your click.


Don’t be panic, that’s how those big companies making use of our personal information. Luckily a VPN like iTop VPN could do something to prevent your private data to be collected.

  • Data Privacy From Your Internet Service Provider

Your ISP or internet service provider—AT&T, Spectrum, Verizon or other company whom you pay for your internet every month can access all your internet data. Theoretically, your ISP can know everything about your usage of the internet and get every piece of data you transfer through their server.


Your data can be collected and sold to advertisers; your personal data could be monetized. And the scenario we discussed above will happen. The privacy leaking can be dangerous in the wrong hands in the case of a data breach. The iTop VPN can help obscure your IP address from your local ISP, thats the reason why VPN is used.

  • Data Privacy From the Apps and Services You Use

Believe it or not, many of our daily apps and services are stealing your location information, your personal address…etc. For example, Facebook has been called out for its “abusively” uses of data collected from its users.

To adapt iTop VPN service could help you to disguise your current coordinate, hide your IP & address so that your precise information could be covered & not to expose to the apps which want to collect your information for their business interests.

  • Data Privacy From Your Government

Your government is very likely, will monitor you through the usage of your internet. It is hard to say if your ISP will cooperate with the government and hand over your information to the government agencies, but the sad news is, it is very likely to happen.


As recently as January of this year, the Defense Intelligence Agency bypassed a law demanding that government agencies produce warrants before compelling phone companies for their user data by paying third-party data brokers for that same data, according to the New York Times. That means if you are not using encrypted communication, you would possibly have your data been seized by the NSA. Your data stored on the cloud service could be monitored if your VPN is without No-log policy.

There are some examples of why & how a free VPN is used for unblocking the regional limited resources online. For example, online streaming platforms like Netflix, Hulu, you can always have different categories in different countries. For example, you are not able to watch Star Trek: Discovery anywhere outside the United States. And there are about 5000+ titles in the Netflix American shop, but there are only 2000+ movies on Italy Netflix catalogs.
