Buying guide
How to choose
Choosing instant messaging software depends on where your team already works and what level of security you require. Look beyond basic chat to consider integrations, compliance certifications, and how well the tool scales across departments. Free consumer apps may suit small teams, but regulated industries typically need enterprise-grade controls.
- 01
Integrations and ecosystem
The tool should connect with your existing productivity stack, such as calendars, project management, and CRM apps, so messages surface contextually rather than in a silo. - 02
Security and compliance
Check for encryption in transit and at rest, SSO support, audit logs, and certifications like SOC 2, ISO 27001, or HIPAA if your industry requires them. - 03
Channels, threads, and search
Evaluate how the tool organizes conversations: public channels, direct messages, threaded replies, and the ability to search historical messages reliably.
Pricing reality
Most team chat tools use per-user-per-month pricing between $3 and $15, with a free tier usually capped at message history or integrations. Enterprise plans with compliance and advanced admin controls typically start around $12-$20 per user per month.
Frequently asked questions
Instant messaging software is a tool that lets users exchange text messages in real time, often with features like group channels, file sharing, presence indicators, and searchable chat history. Workplace versions are designed for team collaboration rather than personal communication.
Instant messaging is built for quick, synchronous back-and-forth conversations, unlike email which is asynchronous and often slower. It is lighter weight than video conferencing and is usually used alongside video calls rather than replacing them.
Free tiers from tools like Slack, Microsoft Teams, and Google Chat can work for small teams, but they typically limit message history, integration counts, or admin controls. Larger or regulated organizations usually need paid plans for compliance, security, and retention.
