Is Discord End-to-End Encrypted? No for text. Yes for most voice and video. Discord text chat, in server channels and in direct messages, is not end-to-end encrypted. Discord stores those messages and can read them. Voice and video are a separate system. On May 18, 2026, Discord said that as of early March 2026 every voice and video call in direct messages, group DMs, voice channels, and Go Live streams is end-to-end encrypted by default,...

On that plan you can view and search messages and files from the last 90 days. Slack hides anything older, and it permanently deletes messages and files more than one year old. You can install up to 10 apps, and huddles are one-to-one only. Diode Collab is private team...

Is Microsoft Teams End-to-End Encrypted? No — not for chats, channel messages, or files. Teams encrypts that content in transit and at rest. By default Microsoft holds the keys. With Microsoft Purview Customer Key, the tenant supplies root keys for another at-rest layer and authorizes Microsoft 365 to use them for services such as eDiscovery and search. Messages stay available to Microsoft 365 services, to compliance tools, and to Microsoft Copilot when the signed-in user...

A Secure Discord Alternative for Teams A secure Discord alternative for teams is a collaboration app that keeps encryption keys on your own devices, does not ask members for government ID, a phone number, or an email address, and does not store readable chat and files in a vendor database. Diode Collab fits that description: it is a local-first team app with end-to-end encrypted chat and files organized into private Zones, plus optional remote access...

Self-Custody Slack Alternative A self-custody Slack alternative keeps encryption keys on participating devices instead of giving a collaboration vendor a universal workspace key. With Diode Collab, chat and files are local-first and encrypted, and no chat, files, accounts, or PII are held on a Diode vendor server for the vendor to read in the normal service model. This is different from self-hosting a chat server: self-hosting means your organization runs the server, and that server...

Choose Diode Collab when your priority is local-first collaboration with device-held keys, no chat, files, accounts, or PII on a Diode vendor server, and encrypted files plus ZTNA remote access in one product. Both support serious privacy goals, but they place responsibility and trust...

Both can serve teams that...

Short Answer: Yes Yes—under normal product operation, Slack’s infrastructure can access and process workspace message content. Slack has to receive and handle readable content to deliver messages, make them searchable, synchronize them across devices, and power features enabled for your workspace. Depending on the plan, settings, and permissions, workspace owners and administrators may also have visibility through exports or compliance tools. Slack AI and third-party apps can create additional processing paths. That does not mean...
