ProtonMail options overview

ProtonMail makes use of robust end-to-end encryption requirements for e-mail and shops all messages and attachments encrypted at relaxation (however not e-mail topic traces). Except for the end-to-end encryption, ProtonMail has a number of fascinating options, together with:

  • The flexibility to ship “self-destructing messages,” messages that are robotically deleted on the time the sender specifies.
  • Handle Verification, a approach to make sure that a Public Key obtained from one other person hasn’t been tampered with because you first verified it.

  • Encrypted Search

ProtonMail firm historical past, buyers, and funding sources

The ProtonMail household of merchandise is run by Proton Applied sciences AG, an organization primarily based in Geneva, Switzerland. The founders met whereas scientists at CERN and got here up with the concept for ProtonMail within the CERN cafeteria, because the story goes. The corporate was initially funded via an Indiegogo crowdfunding marketing campaign which introduced in over half 1,000,000 {dollars}, tremendously exceeding their very own targets. As they claimed within the marketing campaign,

We firmly imagine that ProtonMail can solely achieve its mission if it stays unbiased. By elevating cash via crowd funding, we will make sure that our first and solely precedence is defending the privateness of our customers.

Satirically, lower than a 12 months later, nevertheless, ProtonMail accepted a $2 million “funding” from a US-based agency referred to as Charles River Ventures (CRV). In the present day the corporate is funded via enterprise capital corporations, authorities our bodies, numerous buyers, and customers who improve from the free service plan to one in all three paid plans.

One other fascinating funding got here from the European Union. In March, 2019, ProtonMail accepted €2 million from the EU to “develop a collection of encrypted providers.” Again in 2016, when responding to accusations associated to their involvement with Radware, ProtonMail defined that the corporate additionally receives monetary help from the Swiss authorities:

ProtonMail is a beneficiary of economic help from the Swiss authorities, and we additionally adhere to a coverage of strict neutrality.

ProtonMail doesn’t encrypt e-mail topic traces

One concern I’ve is that ProtonMail doesn’t encrypt the topic traces of messages:

All ProtonMail information at relaxation and in transit is encrypted. Nonetheless, topic traces in ProtonMail will not be end-to-end encrypted, which suggests if served with a sound Swiss court docket order, we do have the power to show over the themes of your messages. Your message content material and attachments are finish to finish encrypted.

Addressing-related metadata should stay unencrypted to permit a message to succeed in its vacation spot.

The ProtonMail strategy makes them compliant with the PGP specification, however leaves this necessary non-public information uncovered to 3rd events. We’ll return to this necessary topic beneath.

ProtonMail servers and information safety

All ProtonMail servers are bodily positioned in Switzerland in safe amenities. This implies person information is protected by Swiss regulation, which usually offers for higher privateness than USA or EU regulation. Nonetheless, ProtonMail makes it clear that they’ll flip over no matter data they’ve on you to the Swiss authorities if ProtonMail believes you may be violating Swiss legal guidelines. That is the place the shortage of encryption for the Topic line of messages can change into an issue.

Whereas the our bodies of your messages and any attachments ought to stay safely encrypted, addressing data and the Topic traces of your messages are saved within the clear and can be offered to the authorities. This data is sufficient to give anybody possessing it a good suggestion of who you talk with and the themes you focus on with them.

Some individuals additionally query how freed from USA and EU affect Proton Applied sciences actually is. They’ve two worldwide help facilities, one in San Francisco, California (USA), and one in Skopje, Macedonia (Macedonia is a candidate for EU membership).

All that mentioned, the ProtonMail menace mannequin doc particularly states that, “we can’t assure your security in opposition to a robust adversary.” The spy businesses serving the USA and EU undoubtedly qualify as “highly effective adversaries.” So for those who resolve to tackle one of many 5 Eyes, violate Swiss legal guidelines, or one thing equally loopy, utilizing ProtonMail is unlikely to save lots of you.

ProtonMail technical specs

ProtonMail makes use of quite a lot of encryption algorithms to guard your messages. All messages are end-to-end encrypted and in addition stay encrypted in your mailbox till actively being learn. The algorithms they use are open supply variations of AES and RSA together with OpenPGPjs algorithms:

  • AES-128
  • TLS 1.0
  • DHE RSA
  • SHA 3

QuoVadis Trustlink Schweiz AG indicators SSL certificates for ProtonMail. Security measures of the certificates embrace:

ProtonMail hands-on testing

In the event you’ve used e-mail providers like Microsoft Outlook or Gmail, you can see ProtonMail to be straightforward to work with. For this overview, we’ll be trying on the free, browser-based consumer, which is the model you’re most certainly to make use of.

Creating an account with ProtonMail is fairly self-explanatory. You may get a free account in a matter of minutes by making a username and password, after which going via the verification steps.

Subsequent you’ll need to undergo a verification course of, however you do have completely different verification choices you’ll be able to choose (Captcha, e-mail, SMS, and many others). I’ve seen complaints about ProtonMail forcing individuals to undergo telephone (SMS) verification when signing up via VPNs or over the Tor community. Though I don’t like how ProtonMail is using SMS verification, you will need to shield the service from spammers and bots.

Signing in to ProtonMail is simple and simple. Merely go to the homepage and enter your login credentials. When utilizing ProtonMail, you’ve got the choice to create a restoration e-mail inbox, which can be utilized for those who lose your password.

The feel and appear of ProtonMail

ProtonMail has a reasonably commonplace interface, with a 3-pane “Column View” structure, in addition to the “Row View” possibility right here:

Under is the default Column view structure once more. You may customise the structure of your ProtonMail inbox in Look > Format > after which choose the structure and composition fashion.

With Column View, you get all the standard folders within the left-most pane, with the power so as to add any customized ones you would like. Within the heart is the message listing, with the physique of the chosen message displayed within the right-most pane. You’ll discover that like different privacy-oriented mail providers, ProtonMail blocks distant content material like photos by default, providing you with the choice to load them proper on the prime of the window.

Choosing the Folders/Labels hyperlink within the left-hand pane offers you a wide variety of settings and different choices, together with filters, guidelines, whitelists, and blacklists.

Customers of the free model can create one filter, whereas paid customers get limitless filters.

Composing messages

You compose ProtonMail messages in a pop-up window with a very good set of HTML formatting choices, together with inline photos. When you get used to the structure, the composition window makes together with issues like Attachments, an Expiration time, a Learn Receipt Request, Encryption quick and simple.

There are a couple of keyboard shortcuts that assist with composing messages. However you gained’t discover extra superior enhancing options comparable to macros and automated strategies.

Sending messages to non-ProtonMail customers

Like another safe e-mail providers, comparable to Tutanota and Mailfence, ProtonMail offers you the choice to ship encrypted messages to individuals who don’t use ProtonMail. The recipient might want to know the shared password you’re utilizing, so that may should be organized outdoors the system. These encrypted messages robotically expire in 28 days (however you’ll be able to set a shorter date if you want).

The recipient will see one thing like the next of their Inbox. In the event that they enter the right password and click on the View Safe Message button, they’ll have the ability to see the message you despatched them.

This appears to work nicely.

Trying to find messages in ProtonMail

ProtonMail has a restricted capacity to go looking your messages. As a result of messages are encrypted besides if you are truly viewing them, the consumer can’t search message our bodies. This, after all, could be irritating and actually restrict your capacity to search out the message you’re in search of.

Up to date search performance: Model Four of ProtonMail is meant to have improved search functionality, so for those who want the power to go looking inside message our bodies, they need to be caring for you quickly.

The ProtonMail consumer works easily though there generally is a delay when opening a message, on condition that the message should be decrypted earlier than you’ll be able to learn it. Because the consumer is browser-based, as a substitute of a stand-alone app, you would possibly discover that it slows down because the variety of messages in your folders improve, however I wasn’t capable of take a look at this.

Comparability to Tutanota search: Compared, Tutanota (one other fully-encrypted e-mail supplier) has been providing full-text search capabilities since 2017. To do that, Tutanota creates an encrypted search index which might then be searched domestically on the customers’ machine.

The ProtonMail Cellular Apps

ProtonMail has apps for each iOS and Android. I’ve been working with the Android app and it seems to be good and capabilities easily. On the time of this overview, the Android app had over 19,000 evaluations with a strong ranking of 4.6 out of 5 stars.

On the time of this overview, ProtonMail’s Android app shouldn’t be open supply and isn’t accessible on F-Droid.

Is ProtonMail actually safe?

There may be quite a lot of debate on the market about how safe ProtonMail actually is.

Except for the considerations about connections to the USA and EU that we mentioned earlier, there have been some criticisms of the service on different grounds as nicely.

  • The browser consumer makes use of JavaScript encryption libraries. These are thought-about to be much less safe than the libraries used within the ProtonMail cellular apps.
  • Leaving the Topic area within the clear (for PGP compatibility) means extra information uncovered to anybody spying on the message visitors.
  • A paper printed on the finish of 2018 criticized ProtonMail’s cryptographic structure on various grounds. Nonetheless, these identical criticisms might be utilized to any browser-based e-mail consumer (not simply ProtonMail). Right here is the response from ProtonMail.
  • 4. In Might of 2019, a put up at Steiger Authorized (archived) claimed that ProtonMail voluntarily gives help to the Swiss authorities for real-time surveillance of customers, above and past any cooperation required by regulation.

We’re going to discover the final problem in a bit extra element.

Does ProtonMail voluntarily cooperate with real-time surveillance?

As Martin Steiger initially claimed on his web site (archived),

E mail service supplier ProtonMail, primarily based in Switzerland, gives help for real-time surveillance: Voluntarily!

This perception goes again to public prosecutor Stephan Walder, who heads the Cybercrime Competence Middle within the Canton of Zurich in Switzerland:

On 10 Might 2019, Mr. Walder gave a presentation on the prospects and limits of legal prosecution at a seamless training occasion on the digitization of legal regulation and legal process. Mr. Walder by the way talked about as a constructive instance that ProtonMail voluntarily gives help for real-time surveillance. Public prosecutor Walder had anticipated that he must receive a federal court docket determination.

On Twitter, ProtonMail repeatedly prevented to handle the query why real-time surveillance was carried out voluntarily. As an alternative, ProtonMail careworn that the contents of the communication couldn’t be monitored on account of end-to-end encryption.

After posting this data, the general public prosecutor claimed he had been misquoted, whereas ProtonMail supplied an official rebuttal to those accusations. Steiger has since eliminated the put up.

For the sake of readability, we’ll merely look at ProtonMail’s transparency report.

Actual-time surveillance of ProtonMail customers?

Upon receiving a judicial order, ProtonMail is obliged to supply any person data available that will assist determine a person that’s topic to a legal investigation that has been validated by Swiss authorities. Along with the objects listed in our privateness coverage, in excessive legal circumstances, ProtonMail may additionally be obligated to watch the IP addresses that are getting used to entry the ProtonMail accounts that are engaged in legal actions.

And in addition:

In April 2019, upon the order of the Swiss judiciary in a case of clear legal conduct, we enabled IP logging in opposition to a selected person account which is engaged in unlawful actions which contravene Swiss regulation. Pursuant to Swiss regulation, the person in query will even be notified and afforded the chance to defend in opposition to this in court docket earlier than the info can be utilized in legal proceedings.

Verdict: Any e-mail service might be pressured to do that by a sound court docket order. This isn’t restricted to ProtonMail. Nonetheless, if you’re utilizing a good VPN service that conceal your IP handle and placement, you’ll nonetheless be protected in opposition to IP logging/monitoring.

Voluntary help to authorities?

Within the second quarter of 2016, we obtained an order from Swiss authorities on behalf of German authorities requesting data in a case the place a minor was in danger. We complied with the order which was subsequently delivered to our workplace by registered put up. It’s ProtonMail’s coverage to all the time help authorities in circumstances involving pedophilia or terrorism.

Verdict: Because of confusion with the outdated transparency report, ProtonMail has edited the textual content to make clear that they DO require a court docket order, however they DO NOT require it to be obtained earlier than they take motion.

All e-mail providers (and companies) should abide by the regulation within the jurisdiction the place they’re positioned, together with lawful court docket orders. Just like ProtonMail, different safe e-mail suppliers additionally put up transparency stories detailing these circumstances for his or her customers. See for instance with Mailfence, Tutanota, and Posteo.

ProtonMail enterprise options

ProtonMail additionally gives a service for companies that gives “end-to-end encryption to safe your enterprise communications.” This service contains migration instruments and devoted help to transition your enterprise from its present internet hosting to the ProtonMail infrastructure. It incorporates a person hierarchy permitting your E mail Directors to handle person accounts appropriately.

ProtonMail price and pricing plans

Since they don’t show advertisements of their shoppers, or promote entry to your messages to advertisers, ProtonMail costs for his or her providers. As you’ll be able to see right here, ProtonMail has 4 pricing plans, together with a free tier.

The Free plan, with 500 MB of storage, 150 messages per day, and three folders / labels might be sufficient for you. If not, one of many paid plans will probably meet your wants. Word that the Free, Plus, and Skilled plans all provide ProtonVPN as an possibility, whereas the Visionary plan has the VPN inbuilt.

ProtonMail alternate options

Whereas there are a number of safe e-mail providers in the marketplace, Tutanota is the primary different I might counsel. Relatively than utilizing PGP and S/MIME, Tutanota has rolled out their very own encryption commonplace incorporating AES and RSA, which encrypts the topic line, helps ahead secrecy, and could be up to date/strengthened over time. Tutanota has rolled out a fully-encrypted Calendar characteristic and is significantly better than ProtonMail about open-sourcing their shoppers.

My verdict: Tutanota is the perfect different to ProtonMail within the high-security class. There are different alternate options to ProtonMail that provide a lesser diploma of encryption and safety, however with extra options. Mailfence and Posteo, for instance, are two different good choices.

Backside Line

ProtonMail is a cultured and fashionable end-to-end encrypted e-mail service that may meet the wants of many common customers. As the most well-liked safe e-mail service in the marketplace, with a free fundamental account, it’s a nice possibility for normal encrypted communications with pals, enterprise companions, and others who need safety from routine snooping and hacking. For many who need most safety, with full encryption of topic traces and robust information safety, Tutanota may be a greater match.

Is ProtonMail the perfect safe e-mail service for you? I can’t let you know that since everybody’s wants are completely different. There are various elements to think about when deciding on a safe e-mail supplier and the selection all comes all the way down to your personal preferences.

In the event you’re open to alternate options, you’ll be able to see my information highlighting the greatest safe e-mail providers.
