Setting up a secure guest network on your Ubiquiti UniFi Access Point can seem like a daunting task. However, by following a structured approach, you can create a robust and secure guest WiFi environment. In this article, we will guide you through the essential steps for configuring a secure guest network using Ubiquiti’s powerful UniFi ecosystem.
The first step to establishing a secure guest network is understanding the components involved. Ubiquiti UniFi is a series of networking devices designed to provide powerful and scalable wireless network solutions. These devices, combined with the UniFi Controller software, offer extensive customization options to enhance security and usability.

Why Secure Guest Networks Matter
In today’s digital age, network security is paramount. Allowing guests access to your network without stringent security measures can lead to credential theft, unauthorized access, and potential data breaches. A well-configured guest network ensures that your primary network remains secure while providing a seamless experience for your visitors.
Setting Up Your Ubiquiti UniFi Access Point
Before diving into the specifics of securing a guest network, let’s start with the basic setup of your Ubiquiti UniFi Access Point.

Initial Configuration
To begin, connect your UniFi Access Point to your network via Ethernet. Open the UniFi Controller software, accessible through the cloud or a local installation. Following the onscreen instructions, adopt your access point into the UniFi Controller. Once adopted, give it a descriptive name to easily identify it later.
Creating a Guest Network
With your access point connected and adopted, the next step is to create a Guest Network. Navigate to the Networks tab in the UniFi Controller and click on “Create New Network.” Here, you will define the network type as “Guest” and provide a unique SSID for the guest network. Ensure that the “Guest Network” option is enabled, which isolates guest traffic from your main network.
Wireless Settings
Configuring the wireless settings for your guest network is crucial. In the settings menu, select WPA2 or WPA Enterprise for encryption to enhance network security. For added security, consider enabling a captive portal or guest portal. This requires guests to authenticate before gaining access to the internet, preventing unauthorized use.
Enhancing Security with Radius Server and PKI
To bolster security further, integrating a Radius Server and Public Key Infrastructure (PKI) can provide advanced authentication and encryption options.
Configuring a Radius Server
A Radius Server offers centralized authentication, authorization, and accounting, making it an excellent tool for securing guest networks. In the UniFi Controller, navigate to the “Profiles” tab and select “Create New Radius Profile.” Input the Radius Server’s IP address, shared secret, and relevant ports. This Radius Profile will be used to authenticate devices connecting to the guest network.
Utilizing Cloud PKI and EAP-TLS
Cloud PKI allows for the distribution and management of digital certificates, ensuring that only trusted devices can access your network. By implementing EAP-TLS (Extensible Authentication Protocol – Transport Layer Security), you can require devices to present valid certificates for authentication. This method is highly secure and significantly reduces the risk of credential theft.
Integrating SecureW Cloud and Okta for Enhanced Security Solutions
Leveraging SecureW Cloud and Okta can provide seamless cloud-based security solutions for your network.
SecureW Cloud Integration
SecureW Cloud offers advanced security features, including threat detection and real-time monitoring. Integrating SecureW Cloud with your UniFi network can enhance overall network security by providing insights into potential threats and vulnerabilities.
Okta for Authentication
Okta is a robust identity management service that offers single sign-on (SSO) and multi-factor authentication (MFA). Integrating Okta with your UniFi guest network ensures that users are authenticated through a secure and reliable platform. This integration can be achieved by configuring Okta as a Radius Server in the UniFi Controller.
Advanced Network Security Settings and Best Practices
Beyond setting up a guest network, there are several advanced settings and best practices to ensure maximum security.
Implementing VLANs
Virtual LANs (VLANs) can segment your network, isolating guest traffic from your main network. By creating a VLAN for your guest network, you can prevent guests from accessing sensitive internal resources. Configure VLANs in the UniFi Controller by assigning a unique VLAN ID to the guest network.
Regular Firmware Updates
Keeping your Ubiquiti devices up-to-date with the latest firmware is essential for maintaining security. Regular updates often include patches for known vulnerabilities and improvements in functionality. Check the UniFi Controller for available firmware updates and apply them promptly.
Monitoring and Logs
Regularly monitoring network traffic and reviewing logs can help identify unusual activities or potential security threats. The UniFi Controller provides detailed logs and real-time monitoring tools to keep you informed about your network’s status.
Azure Security Integration
For organizations using Microsoft Azure, integrating Azure Security features with your UniFi network can provide additional layers of protection. Azure Security Center offers advanced threat detection and automated response capabilities, ensuring that your network remains secure against evolving threats.
Configuring a secure guest network using a Ubiquiti UniFi Access Point involves several critical steps, from initial setup to advanced security integrations. By following the guidelines outlined in this article, you can create a robust and secure guest WiFi environment that protects your primary network and offers a seamless experience for your guests.
Integrating Radius Servers, Cloud PKI, and services like SecureW Cloud and Okta can significantly enhance network security. Implementing VLANs and regularly updating firmware are essential best practices to maintain a secure network environment. By taking these steps, you can ensure that your guest network is not only functional but also highly secure.
In an era where digital security is paramount, configuring a secure guest network is no longer optional but a necessity. Follow these steps to create a secure and reliable guest network using your Ubiquiti UniFi Access Point, and enjoy peace of mind knowing that your network is protected against potential threats.
