Comparative Analysis of 3 Business Chat Platforms: Which Messenger Suits Our Company Best?

Jul 14, 2024

Have you ever mistakenly mixed up personal and work-related chats on a messenger? Personal messengers we commonly use are primarily designed for personal use, often not perfectly suited for professional environments. They make it difficult to easily find work messages and often have short data retention periods, risking expiration of important files.

In contrast, business messengers are developed specifically for company operations, supporting various work activities like project management, team collaboration, and real-time communication. They've become essential in today's business environment. Today, we'll introduce three leading business chat platforms.

A business chat platform is a messenger designed specifically for corporate purposes, enabling efficient communication within workplaces. It enhances work efficiency through features tailored for business needs such as tracking work history, file sharing, video and voice conferencing. By dividing groups by project, it facilitates shared file access and offers quicker verification compared to email or phone calls, making it a preferred choice in corporate settings.



2. Advantages of Using Business Chat Platforms

1) Security

When exchanging data using personal messengers, internal data may be vulnerable as it's stored in personal accounts. Personal messengers pose a risk of accidental invitation of external parties to work-related chats, potentially exposing internal information. In contrast, business messengers are equipped with robust security features to prevent data leakage, especially in project-related discussions. They safeguard corporate secrets by blocking external access and enhancing data security through measures like two-factor authentication and encrypted communication. This ensures high security standards, protecting sensitive information effectively.

2) Message History

Next, there's the advantage of quickly accessing work history. Personal messengers make it difficult to review previous messages when invited to new chat rooms, and exchanged images/files often expire after a certain period, complicating historical review. In contrast, business chat platforms allow users to easily access and review conversations and files within the messenger. This capability enables new members to quickly grasp ongoing work progress. Continuous record-keeping promotes information sharing and collaboration within teams, facilitating swift retrieval of past conversations and files, thereby enhancing workflow efficiency.

3) File Sharing

During business activities, there are often needs to exchange large files such as design files or business proposals. Unlike personal messengers with limited file transfer sizes, business chat platforms offer advantages such as longer file retention periods and the ability to share larger files. Additionally, they facilitate easy file versioning, ensuring files can be readily retrieved and reducing the risk of file loss. Moreover, these platforms allow setting access permissions when sharing files, ensuring the security of important documents while enabling collaboration.

4) Increased Efficiency

It helps to separate official and personal conversations to enhance work efficiency. By segregating personal and work-related discussions through channels and groups, you can avoid confusion and create dedicated channels for each team/project. This allows discussions on specific topics to be conducted systematically, and facilitates easy access to information relevant to tasks. Having work-related materials and conversations centralized ensures clarity in decision-making processes and prevents important information from being buried in personal chats.
