ProtonMail and Tutanota are the services I recommend for secured and encrypted email service.
Signal, Wickr, Wire are the messaging apps I recommend for secured and encrypted messaging.
DuckDuckGo is the best alternative to Google for search engine.
Use TOR browser if you care the most about your online privacy.
For mobile, Firefox focus is also a good app for private browsing.
Privacy badger, uBlock origin, uMatrix, HTTPS Everywhere should be highly considered for browser plugins.
Use TAILS operating system if you’re concerned about privacy.
Excellent VPN services according to me are TunnelBear, CyberGhost, NordVPN, ProtonVPN.
Use MEGA service for encrypted cloud storage.
