For more email providers, take a look at Privacy-Conscious Email Services. Please decide for yourself whether if you trust them with your data. For more discussion about safe email providers, please see issue #461.

MyKolab is hosted in Switzerland and benefits from the strong Swiss privacy laws. It is run exclusively with free software and using the service supports the development of Kolab. Also, it lets you export all your data at any time.

Riseup’s services may also be accessed via their Tor Hidden Service addresses. A list is available here.

Why not Hushmail? See 'compromises to email privacy'.

If you have the technical aptitude, consider running your own mail server.

Bitmessage is a promising alternative to email, but it has not yet been audited by security professionals. Use at your own risk. If you decide to try out Bitmessage, make sure to generate a completely random ID to greatly reduce the probability of ID collisions.

RetroShare has not been thoroughly audited by security professionals for possible security issues.

Switching from a proprietary service like Gmail to one of the more transparently-run email services on PRISM Break is the first step to a secure email account.

The second step is getting you and your contacts to encrypt your plain text messages with PGP encryption. This section contains free email clients that support PGP.

Read the Email Self-Defense guide by the Free Software Foundation to learn how to encrypt your email messages.

Here is a guide by Security In A Box to encrypting your email with Mozilla Thunderbird, GNU Privacy Guard (GPG), and Enigmail.

“Pretty Good Privacy (PGP) is a data encryption and decryption computer program that provides cryptographic privacy and authentication for data communication. PGP is often used for signing, encrypting and decrypting texts, e-mails, files, directories and whole disk partitions to increase the security of e-mail communications.”

PRISM Break does not recommended S/MIME email encryption because of its reliance on third-party certificates from central authorities. Read more here.

OpenKeychain together with K-9 Mail provides end-to-end email encryption. An experimental project is GnuPG for Android by the Guardian Project.

Cloud file storage is also available via Chwala/iRony components of Kolab with the capability to integrate various storage backends. Files are accessible via storage layer access options, WebDAV and Kolab web interface integrating Roundcube.

Tarsnap is not recommended on PRISM Break due to its strict copyright on the client that makes it difficult to replace the service in the event Tarsnap is shut down.

BitTorrent Sync, MEGA, and SpiderOak are services that are built on either partially or fully proprietary software. They will not be recommended on PRISM Break until they open source the entirety of their codebase.

With closed source software, you need to have 100% trust in the vendor because there's nothing except for their morality in the way of them leaking your personal information. Even if you can vouch for their integrity, proprietary software invariably has more uncaught security bugs and exploits because there are fewer eyes examining the source code.

Another alternative to cloud storage is local backup with external hard drives and USB flash drives. This method is reliably more secure than storing data on a network, but comes at a convenience cost.

“Off-the-Record Messaging, commonly referred to as OTR, is a cryptographic protocol that provides strong encryption for instant messaging conversations. OTR uses a combination of the AES symmetric-key algorithm, the Diffie–Hellman key exchange, and the SHA-1 hash function. In addition to authentication and encryption, OTR provides perfect forward secrecy and malleable encryption.

The primary motivation behind the protocol was providing deniability for the conversation participants while keeping conversations confidential, like a private conversation in real life, or off the record in journalism sourcing.”

Note that Pidgin stores your IM account passwords in plain text. You can avoid this by (1) not saving your password in Pidgin, (2) encrypting your file system, or (3) storing your Pidgin password securely with the Debian package pidgin-gnome-keyring.

Pidgin with OTR and dbus enabled has a local security bug. See the upstream bug report for more information and possible workarounds.

The Guardian Project hosts a fantastic how-to guide to chatting securely on Android with ChatSecure.

Threema is not recommend by PRISM Break as it is closed source software. Freely available source code is a necessary condition for privacy and security.

A beginner’s guide to running your own mail server is available here: “NSA-proof your e-mail in 2 hours”.

Kolab integrates Roundcube into its webclient and offers desktop clients as well. Recent versions also feature a file cloud turning it into a complete solution for personal information management.

What is an MTA?

“Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. An MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol.

The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.”

Installing your own add-ons into Tor Browser is not recommended, as they may bypass Tor or otherwise harm your anonymity and privacy. Check the EFF's Panopticlick to see how trackable your browser configuration is by third parties.

If you're using a Firefox-based browser, you can safeguard your browsing habits and stop advertising companies from tracking you by installing uBlock Origin, Request Policy, and HTTPS Everywhere.

A more advanced alternative to Request Policy would be uMatrix.

Install NoScript and enable ‘Forbid scripts globally’ to improve the security of your browser by preventing 0day JavaScript attacks. This is a drastic option as it will render many websites unusable as they rely heavily on JavaScript. NoScript offers a whitelist you can use to selectively enable JavaScript for sites you trust, but this is considered especially bad for your anonymity if you're using NoScript with Tor Browser.

Why is Adblock Plus not recommended? Adblock Plus shows “acceptable ads” by default, which works against the purpose of the add-on. Either disable acceptable ads or use uBlock Origin instead.

Use a combination of Tor Browser and a free web browser of your choice to the surf the web.

Try to use Tor Browser as often as possible. Browsing is slower with Tor, but far more secure.

Note: Mozilla Firefox is technically not completely free software, as Mozilla recommends non-free add-ons on their website.

Connect most search engines, RSS/ATOM feeds, Twitter/Identica, Youtube/Dailymotion, wikis, and basically any source of data, and Seeks will produce a fused personalized stream of results to your queries. See list of Web Seeks nodes.

Tor users may use Seeks hidden service at 5plvrsgydwy2sgce.onion.

YaCy is a promising project that offers fully decentralized peer-to-peer search. The more people who start using it, the better the results will become.
