Wire

Commentaires: As an early Wire (personal) adopter and a vocal supporter (I want to say Ambassador), I may be a bit biased. Still, I strongly believe everyone deserves a fully secure communication platform and there must be no compromise on that - Wire proves it's possible.
I have successfully converted more than a couple dozens users to Wire - and we never looked back.

Avantages: First and most of all, Wire is all about security. Full E2E encryption for all the services it provides - messaging, voice, video. There are no compromises here and if security is a top priority, you don't have to look further.
As far as I know, they are already doing some post-quantum cryptography experimenting, which is really impressive.
Did I mention they are 100% Open Source? Did I say the voice quality is absolutely fantastic?

Inconvénients: Not a lot of things I can say I don't like - basically for private usage the only issue is adoption, as the competition is very hard (not that I find any of the competitors good) and most people base the adoption on the number of people already on the platform.
For business usage, I would say that it has everything that most people would want - yeah, including gifs, but it's always hard to adopt a new tool/software for the team, especially a communication platform.

Commentaires: Great value if you only want a secure chat software this is the most robust option. But look elsewhere if you need something that has a lot of 3rd party integration or bots to help with productivity.

Avantages: As a chat app very simple to use and setup. UI is basically chat but nothing else. Self-destroy message makes sharing sensitive info easy. Secure voice calls and video calls quality are surprisingly high. Pricing is very competitive compare to other US rivals. Europe-based company.

Inconvénients: Wire is basically just a chat software. Integrations with 3rd-party almost non-existent. Syncing between devices have issues sometimes that re-sync with new encryption key may be required. Syncing chat history takes longer time than usual.

Commentaires: Not loving it, sometimes really frustrated by it, but it works just well enough to keep around. I don't know of any secure messaging alternatives that work any better...

Avantages: Our organization works with vulnerable communities and needs to be able to communicate securely so we've been looking for an encrypted alternative to Slack for some time now. Wire seemed like the closest fit in terms of the features we wanted: custom "channels" the ability to include some people outside of the org, silo'ed information, and secure group calling. It hasn't been spectacular at any of those things, but it hasn't been terrible either.

Inconvénients: Wire is a pretty new product and it shows. The calls frequently drop, or some people's audio won't connect, etc. etc. Calls generally have to be limited to just a 3-4 people or the quality degrades even further. Our plan to use it as a communication tool with communities has been shelved indefinitely while we wait for some upgrades. In the meantime, our team mostly uses it text each other, which has been a significant improvement over email, but not quite as functional or intuitive as Slack channels. Nevertheless, it seems to be the best thing we've got so we're sticking with it for the time being.

Commentaires: Excellent experience and it is well worth the download. It is encrypted and certainly better than Slack.

Avantages: This is a great software for the workplace. All of my work colleagues are on Wire and we are able to communicate with each other while we are in the office and while we are at home. This software makes working from home very effortless because you can remain in constant contact with your coworkers. You can also turn off notifications from the app if you choose to install the software app on to your phone.

Inconvénients: Sometimes I would like to share files on Wire that are too big. Since some of my coworkers work in the podcasting arena, they have found that sometimes when they try to share their files through wire it is just too big to send, but this has been an issue for us on many softwares.

Commentaires: For now, it is a great app as it is highly recommended by a not for profit organisation that cares for personal privacy and security.

Avantages: Security and Privacy and ease of use. Also, the options to sign up either by phone number or an email.

Inconvénients: Unsure of making bots to prevent sharing suspicious links or prohibiting calls to unknown users.
