Brosix vs Slack

Brosix

• Small offices that want a fixed monthly price for 20 or 50 users
• Healthcare, finance and legal teams that need a closed, admin-controlled network
• Teams without dedicated IT staff that want chat set up in minutes

Slack

• Teams that want conversations organized by channel rather than email threads
• Companies that work with outside partners in shared channels
• Organizations that already run on Salesforce
• Teams that connect many third-party apps to their chat

Brosix

• There is no free plan; every plan starts with a 14-day trial.
• Multiple admins, user permissions, 2FA, custom branding and Active Directory integration are limited to the Ultimate plan.
• Peer-to-peer file transfer, the whiteboard and broadcast messages are available only in the older Windows Classic app.
• End-to-end encryption applies to direct peer-to-peer connections only; messages and shared files are also stored on Brosix's encrypted servers.

Slack

• The Free plan keeps only 90 days of message history searchable, allows 10 apps, and limits huddles and Slack Connect to 1:1.
• SAML single sign-on and SCIM start at Business+; ongoing Slackbot access is on Business+ and Enterprise+, with a limited trial on Free and Pro.
• Enterprise search, multiple SAML configurations and native data loss prevention are limited to Enterprise+, which is priced by sales.
• In a browser, huddles are supported only in Chrome and Firefox.

Brosix

Private team network

Only users an administrator adds can join, so outsiders never appear in a contact list. Admins create and remove users and set who can see whom from a web control panel.

Chat and chat rooms

One-to-one and group chats with replies, mentions, read receipts and edit or delete, plus chat rooms for teams, projects or departments and a searchable history.

Voice and video calls

Audio and video calls between team members are included in every plan, and the Essentials plan cards describe them as unlimited.

Screen sharing and remote desktop

Share a screen or take remote control of a colleague's desktop to sort out a problem, and capture and send screenshots from inside the app.

File transfer

Send files of any size to a person or a group. The Windows Classic app also offers direct peer-to-peer transfer, a whiteboard and broadcast messages.

Encryption and compliance controls

Chat, calls and files are encrypted with AES-256, with end-to-end encryption on direct peer-to-peer connections. Ultimate adds 2FA, IP address permissions and chat history expiration.

Slack

Channels and direct messages

Conversations are organized into channels for each project, topic or team, alongside direct messages. Paid plans keep the full message and file history searchable; Free keeps 90 days.

Huddles and clips

Huddles are audio and video meetings with screen sharing, 1:1 on Free and for groups on paid plans. Clips are recorded audio or screen updates shared in a conversation.

Slack Connect

Message people outside the company. Free allows 1:1 external direct messages; paid plans add group chats and shared channels with up to 250 organizations.

Canvases and lists

A canvas holds text, files, images and video inside Slack, and lists are used to manage projects and organize tasks with teammates.

Workflow Builder and apps

Workflow Builder automates routine processes without code, and the app directory lists more than 2,600 apps. A Free workspace can connect up to 10 of them.

AI in Slack

Pro includes AI conversation summaries. Business+ adds AI search, daily recaps, file summaries, workflow generation and the Slackbot personal agent, subject to plan limits.
