Privacy and Security Tools

Practical software for keeping your messages, passwords, files and browsing to yourself. Most of it is free, and the paid options are cheap compared to the alternative.

17 tools Links out, nothing to install
  1. 1
    Signal Free · non-profit, donation funded

    End to end encrypted messaging with the smallest amount of metadata retained of any mainstream app. The protocol is the industry standard, and the organisation behind it is a non-profit with nothing to sell you.

    Proton Mail Free tier · paid from about $4/mo

    Encrypted mail under Swiss jurisdiction, with calendar, drive and VPN in the same subscription. Search across encrypted mail is weaker than Gmail, which is the honest trade.

    Proton VPN Free tier · paid from about $5/mo

    The only reputable VPN with a genuinely unlimited free tier, audited and open source on every client. The free servers are slow, and they are safe.

    Mullvad Paid, flat 5 EUR/mo

    Buy an account number with no email address, pay in cash if you want, and pay the same flat rate forever. No affiliate programme and no fake discounts, which tells you a lot.

    Tor Browser Free · open source

    Routes traffic through three relays so no single point sees both who you are and what you asked for. Slow by design, and the correct tool when a VPN is not enough.

    Bitwarden Free · paid from $10/year

    Open source password manager with an unusually complete free tier and the option to self-host. The default recommendation for almost everybody.

  7. 7
    1Password Paid from about $3/mo

    More polished than Bitwarden, with better sharing, travel mode and family setup. Worth the money if a less technical household is going to have to use it.

    KeePassXC Free · open source

    A local encrypted vault file with no cloud service in the loop at all. You handle sync and backup yourself, which is exactly what some people want.

    Firefox Free · open source

    The main browser not built on Chromium, with container tabs and strong tracking protection. Keeping it installed also keeps the web from being one rendering engine.

    uBlock Origin Free · open source

    The content blocker to install, light on memory and free of any acceptable-ads arrangement. Full functionality now lives in Firefox rather than Chrome.

  11. 11

    Search without a profile following you around, plus a browser and email forwarding service. Results are behind Google on obscure queries and fine for most of what you look up.

    Cryptomator Free on desktop · paid mobile apps

    Encrypts a folder before it syncs to Dropbox, Drive or iCloud, so the provider holds only ciphertext. Simple, open source and it does not change how you work.

    Full disk and container encryption, the maintained successor to TrueCrypt. Dated interface, thoroughly audited cryptography.

    Tails Free · open source

    A live operating system on a USB stick that routes everything through Tor and forgets the session on shutdown. Built for journalists and sources in genuine danger.

    Standard Notes Free · paid from about $7/mo

    End to end encrypted notes with a long-term commitment to data longevity and open formats. Fewer features than Notion or Obsidian by deliberate choice.

    Check whether your accounts appeared in a known breach and get told when it happens again. Five minutes here is the highest return security work most people can do.
