ProtonMail
ProtonMail is an end-to-end encrypted email service developed by Proton AG in Geneva, Switzerland, available on web, Windows, Mac, Linux, iOS, and Android. All emails are encrypted on Proton's servers using PGP, meaning even Proton cannot access the contents — only the recipient's private key can decrypt messages. Switzerland's strict privacy laws and Proton's independent jurisdiction from US and EU surveillance programmes make it a legally strong choice for sensitive communications. The free plan provides 1 GB storage and one email address; Proton Unlimited adds custom domains, aliases, Proton VPN, Proton Drive, and Proton Calendar. ProtonMail is used by journalists, activists, legal professionals, developers, and businesses handling confidential communications who need email that is both technically and legally resistant to unauthorised access.

Tailscale is a zero-configuration mesh VPN built on the WireGuard protocol, available for Windows, Mac, Linux, iOS, and Android. It creates a private, encrypted network between all your devices and servers — laptops, cloud VMs, Raspberry Pis, and containers — without requiring port forwarding, firewall rules, or a VPN server to manage. Authentication uses your existing identity provider such as Google, GitHub, or Microsoft. MagicDNS assigns memorable hostnames to each device on the network. The free plan supports up to 3 users and 100 devices. Tailscale is used by developers and small teams who need to securely access home servers, self-hosted services, and cloud infrastructure from anywhere without the setup overhead of traditional OpenVPN or WireGuard server configuration.
