In business, you’re either evolving or fading—stagnation isn’t an option."

I see a secure real-time group/chat application as a chance to grow by evolving.

27-Feb-2025

Has this request actually been out there for 10 years?

Must be a lot more work than one might think! A real-time chat that is secure proton user to proton user, and proton user to any app that uses the Signal protocol (most chat apps are heading toward the signal protocol)... with a non-secure method that would connect the proton user to SMS/MMS (RCS?). Apple users will be connected via Signal protocol.

The hard part (IMHO) is getting a reasonable group chat working securely for the proton users and notification on the group when any group member is not secure (not a proton user and a user not connected via the signal protocol) .

Maybe this feature is wishful thinking.

Someone commented that Proton should not expand into new areas, no offense but while sucessful expansion always needs carefull planning to not expand into new areas would kill many businesses, especially when it comes to the tech industry, where remaining stagnant is equivalent to moving backwards, rapidly. We saw that sad demise with BlackBerry, of which I was greatly affected.
I have used Proton and been a beta user from early on, as I'm sure others here have, I'm a recovering crackberry addict and when BB stopped providing secure services for BB users I was very grateful that Proton was there.
Proton has been amazing in the secure services provided, and they have moved way past where they started in whats offered and we need them to continue to expand, one simple feature I have been requesting for some time is an email address book that also doubles as our phone contacts, much like gmail, but better, so I can rely less on google.
Proton is made up of innovative wizards and I believe they could develop the best solution to the problem of secure messaging that would be most universal for all, and in doing so garner many more members in the Proton consumer family. I don't want a monopoly, but I am loyal to the products and services I use and I do want to see Proton flourish all the more. -David

Instant messaging / Voice / video call for groups/individuals.
all encrypted

Instant messaging / Voice / video call .

Replacement for Microsoft teams/ Signal.
All in one Encrypted platform.

With features like in slack or discord, it would be awesome

Switch to Signal owned by Signal Foundation is happening quite fast, but still under US jurisdiction.

A chat module hosted in Europe with good security and already large user base seems both like a commercial killer app as well as something commercially viable.

like signal would be nice

Proton Suite needs a chat/video messaging app similar to MS Teams, especially with the option to screen share/remote control! This would be very useful. Thanks.

yeah something like google chat or slack from proton would be amazing!

It should also be accessible on desktop like google chat is.

I would love this! But don't have it fully locked down like Signal is. Total security from "Proton Messages" (I will use PM to reference it furthermore) users to users, but as much security as possible from PM user to regular phone number. But I do believe that PM could be the next major step for Proton as a whole. That and a full Office suite.

I would recommend focusing on existing features. See also https://protonmail.uservoice.com/forums/945460-general-ideas/suggestions/48603929-focus-on-existing-products

There are 2 excellent products already Signal and Threema (Threema.Work for businesses, I don't think Proton will be able to provide it cheaper) that already covers this requirements.

@NR: Get the Proton Business subscription first, and request through Proton support that you would require this feature. Start supporting Proton first before requesting new features that blows up the Proton Business subscription fees.
There are already a lot of missing basic/essential features that you will encounter once you start using in your clinic on existing Proton products; lets fix them first.
Please, no offense intended :-)

Some users have mentioned that this not an important feature. But
I think this is a critical feature lacking especially from your “proton for business” suite. As a clinic owner, I want to ensure that we can safely send instant messaging (vs sending emails back and forth) about patients within the clinic network. Not having this feature makes me not want to get the business suite from proton and consider another provider.

please

I'm against a Proton Real Time Communication app. I think Proton should stick with what they have and work on that, rather than expanding into new areas.

It should also be accessible on desktop like google chat is.

Desired features:
Enterprise managed group chat space, one-to-one chat, chat rooms, sub groups of users, invitation by email, selectable access per user per room.
Able to suspend users from space, without losing contributions to chats and rooms.
Able to delete users from space, with option to delete any or all contributions to space.
Manageable user logins directory, to delete old device logins.
Compatible for Android, macOS, iOS, iPadOS, Apple Watch.
Installable via Google Play Store, macOS App Store, iOS App Store, iPadOS App Store; does not require manual installs for macOS nor sideloading for iOS and iPadOS.
Integrated with Proton Business Suite.
Complete Apple iMessage emoji support.
Customizable automated scripts for forwarding notifications, based on room and selected level of urgency for a given message: email notifications, popup notifications, text notifications.
Printable views of selectable portions of chat rooms.
Search for keywords in entire space.

This would be cool, and seeing how Telegram is dying, this might actually not be such a bad idea. But the downside to this is that running a "social media" app or messaging app demands using a lot of resources on LEA requests and moderating groups and channels. Thats expensive. And if you don't do it, proton CEO might get arrested while on holiday in France.

There are several good options out there that we're all familiar with, but if those options satisfied our needs and wants we wouldn't be discussing this. I would like to see Proton's vision in a Messaging & Voice-Video Calling app - an alternative to (and combining the best of) WhatsApp, Signal, Telegram, and MySudo - done the Proton way with the Proton interface. As another commenter stated, it would likely be based on the Signal platform.
