✔
Real-time messaging (1:1 or group chats)

Searchable history (no lost conversations)

Organized Communication with Channels
Instead of endless email chains, Slack uses

1,500+ apps, automating workflows:
- Google Calendar for meeting reminders
- Trello for project updates
- Zoom for instant video calls
Secure & Scalable
Slack offers enterprise-grade security, including:
🔒 End-to-end encryption
🔒 Compliance certifications (HIPAA, GDPR)
🔒 Custom user permissions
