  • Keep your security app updated.
  • Submit online payments only with buyer protection.
  • Use a VPN when connecting to the internet from public and unsecured wireless networks.
  • Pay attention to the passwords you have assigned to your online accounts. They have to be strong, including capital and lowercase letters, numbers, and symbols (@, !, %, #, etc.).
  • Make sure that the information you send is over secure connections. The online website extension has to be HTTPS://and not HTTP://


When should I use Bitdefender VPN?

You have to be careful when you access, download, or upload content on the internet. To make sure you stay safe while browsing the web, we recommend you to use Bitdefender VPN when you:

  • Want to connect to public wireless networks.
  • Want to access content that normally is restricted in specific areas, no matter if you are home or abroad.
  • Want to keep your personal data private (usernames, passwords, credit card information, etc.)
  • Want to hide your IP address.


Will Bitdefender VPN have a negative impact on the battery life of my device?

Bitdefender VPN is designed to protect your personal data, hide your IP address while connected to unsecured wireless networks, and access restricted content in certain countries. To avoid unnecessary battery consumption of your device, we recommend you to use the VPN only when you need it and disconnect when offline.


Why is my Internet slow while connected to Bitdefender VPN?

Bitdefender VPN is designed to offer you a light experience while surfing the web; however, your internet connectivity or the server distance you connect to may cause a slowdown. In this case, if it is not a must to connect from your location to a faraway hosted server (e.g. from the USA to China), we recommend you to allow Bitdefender VPN to automatically connect you to the nearest server, or find a server closer to your current location.
