Flying Under the Radar
Staying secure on public networks is important, especially for secret agents. Try using 1.1.1.1 as your DNS, use a VPN service, and try a Tor browser when you want to keep things on the down low. 1.1.1.1 also offers an iOS app with its own VPN. Another great VPN option is Zoog VPN which is available on both iOS and macOS.
