A hidden SSID (Service Set Identifier) refers to a wireless network that is configured not to broadcast its name (SSID) publicly. Typically, when you set up a Wi-Fi network, the SSID is broadcast by the wireless router, allowing nearby devices to see and connect to the network. However, in the case of a hidden SSID, the network’s name is not openly advertised.
Here are some key points about hidden SSIDs:
- Manual Configuration: To connect to a hidden SSID, users must manually enter the network name (SSID) and the network’s security key (e.g., password) into their device’s Wi-Fi settings. Without this information, they won’t be able to see or connect to the network.
- Enhanced Security: Some users choose to hide the SSID as a security measure. While it’s not a foolproof security method (since tools exist to discover hidden SSIDs), it can deter casual or unauthorized users from attempting to connect to the network.
- Reduced Visibility: Hidden SSIDs are not visible in the list of available networks when users scan for nearby Wi-Fi networks on their devices. As a result, users must know the SSID in advance to connect to the network.
- Configuration Challenges: Hidden SSIDs can be less user-friendly, as users need to manually input network details. This can be cumbersome, especially when dealing with devices that have limited input capabilities.
- Not a Substitute for Strong Encryption: While hiding the SSID can enhance security, it should not be the sole security measure. It’s crucial to use strong encryption methods like WPA3 or WPA2 (with a strong passphrase) to protect your network’s data.
- Not Perfectly Secure: It’s important to note that hiding the SSID is not a guarantee of network security. Determined attackers can still discover hidden SSIDs using specialized tools.
- Potential Downsides: Hidden SSIDs can have some downsides. For example, if a user needs to connect multiple devices to the network, manually entering the SSID on each device can be time-consuming.
In summary, a hidden SSID is a Wi-Fi network that does not broadcast its name publicly, requiring users to manually enter the SSID to connect. While it can provide an additional layer of security, it should be used in conjunction with other security measures to protect a wireless network effectively.

Fiber Internet
Internet delivered through strands of glass using light. Fiber commonly supports high capacity, low latency, and strong upload performance, but availability must be confirmed for the exact address.
Cybersecurity
The practices and controls used to protect identities, devices, networks, applications, and data from unauthorized access, disruption, or manipulation.
Zero Trust
A security model that does not automatically trust a user or device because of its location. Access is continuously verified and limited to what is necessary.
SASE
Secure Access Service Edge combines networking and security capabilities in a cloud-delivered architecture so users and locations can receive consistent policy wherever they connect.
Identity and Access Management (IAM)
The systems and policies that determine who a user is, what resources they may access, and how that access is authenticated and reviewed.
Multi-Factor Authentication (MFA)
A login control requiring more than one form of verification, such as a password plus an authenticator app, security key, or biometric factor.
