Security and deployment

The system is designed for local-network operation. For IT teams, the most important points are attack-surface minimisation, access control together with clear logs and readable history.

LAN-first

The system can run in a closed network without internet exposure.

Segmentation

Targeting groups and subnets reduces unnecessary noise and the risk of mistakes.

History / audit

You can quickly see what was sent, when, to whom and with what status or receipt.

Recommended deployment model

Most often: server + web panel in LAN (VM or physical), with clients on user workstations.

• Gdzie stoi serwer (VM/fizycznie)?
• Should the web panel be accessible only from the admin network?

• Which notifications should require read receipts?
• How long should history be retained?
