Should I use a VPN while being connected to the internet? What is a VPN? VPN is a service that grants you complete online anonymity by encrypting all incoming and outgoing traffic on your PC, Mac, or mobile devices. Hardware based VPNs like the cisco VPN(hardware device Meraki) allows an encrypted VPN connection with the corporate network while working at home. A software-based VPN at home is for example Bitdefender VPN. During your hotel stay you should use a VPN. (Bitdefender VPN), using the hotel Wi-Fi. At the airport it is also important to whom you connect to. I recommend the hotspot connection on your phone and not the free Wi-Fi connection offered by a lot of carriers. If you are extra precautions, use the VPN in combination with your hotspot, be aware that VPN encryption will slow down the internet speed.
