Yes, it is possible to further increase security by integrating Mattermost into your company network via a VPN (Virtual Private Network).
What is a VPN?
A VPN (Virtual Private Network) establishes an encrypted and secure connection between a device (e.g., laptop or server) and the internal company network via the Internet. You can think of it as a protected tunnel through which all data is transmitted. This ensures that no unauthorized third parties can read or manipulate the data traffic.
How does a VPN increase the security of Mattermost?
By integrating Mattermost into your VPN, you benefit from several advantages:
- Access restriction: Access to the application is only possible via the VPN. This means that Mattermost is not publicly accessible on the Internet, which significantly reduces the attack surface.
- Encrypted transmission: All data, including sensitive documents and login details, is transmitted in encrypted form.
- Integration into your internal network: You can configure Mattermost to communicate with other internal systems such as file storage, user directories (e.g., Active Directory), or backup solutions.
Implementation in practice
To set this up, you need a VPN server (e.g., with WireGuard, OpenVPN, or a firewall appliance) that is operated within your company network. You can then configure Paperless-ngx to only accept requests from the VPN—for example, via firewall rules or the web server configuration. Employees then connect to the company network via VPN access to access Mattermost.
Overall, this solution is a very effective measure for significantly increasing the security and data protection of your team chat.
