Top Reasons Why You Need VPN?

1. Avoid Man-in-the-middle attack

Nowadays, free WiFi hotspots are available almost everywhere at public places, e.g. hotel, shopping malls, restaurants, metro stations, etc. Most WiFi hotspots are not encrypted. That means anyone can sniff that air and see what everyone is doing. Imagine that when you are online chatting with your girl/boy friend, some stranger around you is smiling at you. He/she may know what you are chatting about.

The worse thing is when you are online shopping through public WiFi hotspots, sophisticated hacker can steal your password, credit card number, SSN, etc.

You may think you are safe because you only use public hotspots that are password protected. But keep in mind that the hotspot is for public. The hackers know that password, too. They can still see all your online activities. And do man-in-the-middle attack.

 

Also hackers may spoof a Wifi hotspot. The figure above shows the simplest hacking example. A hacker spoof a WiFi hotspot with well known hotspot name "xfinitiwifi" in public space, e.g. shopping malls, metro stations, etc. He is sniffing all traffic going through this WiFi hotspot, analyzing traffic and carrying man-in-the-middle attack.

With this VPN server device , you are worry-free. After VPN tunnel created between your smartphone and VPN server, all your online activities are encrypted between your smart phone and VPN server at your home. That means, any man in the middle (i.e. hackers at WiFi hotspots) cannot see what's in the packets. If any packet is modified by hackers, the packet integrity check failure would detected by VPN tunnel, therefore discarded. This eliminates any man-in-the-middle attack.

Now you can confidently say "Thanks you Hacker, for providing free WiFi internet access" :)

 

2. Keep your online privacy

        Your company may provide free WiFi access. But you were told that the internet use is monitored by company. Although your company won't do the man-in-the-middle attack, you still don't feel comfortable that wherever you go, your company knows.

This VPN service is right for you*. No matter which website you go, they all appear as if you connect to your home. And the contents are encrypted by the strongest algorithm.

*Before using this product at work, check with your company policy whether IPsec VPN is prohibited. Buyers are to take full responsibility when using this product.

3. Access home network anytime anywhere

   

With VPN tunnel to home, your smart phone is virtually at home no matter where you go. You can access all network cable devices there are only accessible to home network. e.g.

• You may have IP camera at home monitoring home or baby.
• You can access your network capable printers at home.
• The next big thing is Internet-of-Things. More and more devices will be network connected at home. With VPN tunnel to home, it is just a piece of cake for you to control/monitor your home anywhere any time.

4. Avoid IP blockage when you are overseas

    There are countries that have explicitly blocked some US websites by firewall. e.g. certain Asian countries explicitly blocks Gmail, facebook etc.. When you travel to such countries and you need to check emails or post photos on your Facebook page, you can simply turn on VPN on iphone/android or Windows PC. The VPN encrypted tunnel only appears to the firewall as traffic goes home, NOT to Gmail or Facebook.

 

5. Access Entertainment streaming that limit access from within a region

A very popular use case among international students and visitors is to access entertainment/TV streaming that limit access only to IP from home country.

In this example, visitors from China can use iPad to connect to VPN server at home in China. This way, he/she can access the China TV streaming that limits access only from within China. The VPN server makes the iPad from US appear from within China. Also, in same way, his/her family in China can access US entertainment streaming that limits access only from within US.
