Business Wi-Fi security: guest networks, passwords and the basics

Why separation is vital

For business Wi-Fi security, the golden rule is isolation. Your guest Wi-Fi must be on a completely different network than your internal business systems. If a guest brings a device with malware, you want to ensure it cannot reach your servers, printers, or workstations.

Essential Wi-Fi security steps

• Change defaults: Never use the factory-set passwords.
• Guest isolation: Set up a dedicated, isolated guest network.
• Encryption: Use WPA3 or the strongest standard your gear supports.
• Maintenance: Regularly update your network hardware software.

Password management

Change your Wi-Fi password if a staff member who knew it leaves the company. Likewise, periodically update your guest network password. A secure network is a managed network.
