July 16 2022: Summer travel plans typically include busy airports,  public places like malls and restaurants in foreign countries—where one might be checking one’s email, sending  WhatsApp messages,  uploading Facebook posts. No one knowingly puts "get hacked over public wifi" on their itinerary – but that is what happens to so many tourists.
By turning on Virtual Private Network on your phone or laptop, you protect your passwords from getting swiped by a hacker on the same network as you and enjoy some peace of mind. No one can log your network activity.
ou may already have installed VPN. But if not, here’s some help:
Mozilla, makers of the free  Firefox browser  are promoting their switch-on VPN. 
You can connect up to 5 devices without bandwidth restrictions.  Mozilla VPN links to 400+ servers in over 30 countries, but it  is currently limited to  use in Austria, Belgium, Canada, Finland, France, Germany, Ireland, Italy, Malaysia, the Netherlands, New Zealand, Singapore, Spain, Sweden, Switzerland, the UK, and the US.
Sadly Indian’s can’t enjoy a free VPN  service in their own country. The government’s  Computer Emergency Response Team  requires  all  VPN service providers to log details of all the persons who access their servers  starting  June 28.  
Claiming that this would nullify the  core USP of VPN and render their privacy-oriented business model meaningless, many VPN providers including  Surfshark, NordVPN and ExpressVPN have  withdrawn their servers from India  stopped their services to  India-based enterprises.
And if you enjoyed VPN free as part of a consumer Net Security service from players like McAfee or Norton, you may have already received a notice that the option to switch on your VPN is no longer available in India.However once you are outside India,  theVPN  that comes with the security app on your device  will start working.
