Are Hidden Networks More Secure?

Or maybe you have seen hidden networks on your available WiFi list and wondered what it is and why it is showing.
Do you have a hidden network yourself but are unsure if they are more secure or not?

In this blog we will look into hidden networks, what they are, if they are worth it and if they are more secure than an unhidden network.

What is a Hidden Network?

A hidden network is a WiFi network that doesn’t broadcast its name (SSID), so it won’t appear in the list of available networks for nearby devices. Unlike standard WiFi networks, where the SSID is visible and users can connect easily, with a password or not, a hidden network requires users to manually enter the exact SSID to connect. The main idea behind hiding a network is to add an extra layer of security by reducing its visibility to unauthorised users. However, it’s important to understand the real impact on security and consider best practices for protecting your network.

How to Find Hidden Networks

There are several methods to find hidden WiFi networks, ranging from simple to advanced.

Most operating systems have built-in tools to display all wireless networks, including hidden ones. For example, on Windows, you can use command prompt commands to reveal hidden networks.

WiFi Scanning tools can detect all networks in an area, including those with hidden SSIDs. They often provide additional details like security types and network features.

WiFi Penetration Testing Tools are designed for security professionals, these tools assess network security and detect hidden networks. They require technical knowledge to use effectively.

As you can see, finding a hidden network can be quite easily done if you know how. Once favoured by security-savvy users, hiding your network was thought to prevent unauthorised access by making the network invisible, akin to a secret doorway to your home. However, this practice has fallen out of favour. Modern tools can easily detect hidden networks, meaning that hiding your SSID isn’t as secure as once believed. Today, more robust security measures are recommended to protect your network effectively.

While hidden networks offer a layer of obscurity, they are not entirely invisible. Standard tools and apps can detect them, though understanding and using this information may require basic knowledge of WiFi networks.

However, while tools exist to detect hidden networks, the average user typically won’t search for something they don’t know exists. hiding your network offers limited security benefits.

Are Hidden Networks More Secure?

Hidden networks might seem secure because they don’t broadcast the SSID (network name), but this doesn’t improve actual security. Some users feel safer hiding their network, although a strong password and secure network protocols are far more effective. Having said that, hiding a network can provide peace of mind by keeping it out of sight, especially in shared living situations or work environments where separating guest and internal networks is beneficial.

A hidden network is neither safer nor less safe than a visible one. Network safety depends on the owner’s security measures. Always know and trust the network you’re connecting to before accessing it.

WiFi Security

While hidden networks are not inherently problematic, ensuring the security of your WiFi is crucial. Here are some actionable tips:

• Use Strong Passwords: Create a robust password combining letters, numbers, and symbols.
• Regularly Update Passwords: Change your WiFi password periodically to prevent unauthorised access.
• Separate Networks: For businesses, establish separate networks for guests and main devices to keep guest devices off your primary network. SDWAN will help with network segregation
• Firmware Updates: Regularly update the firmware of your router and connected devices to fix security vulnerabilities. Professionals like Performance Networks can ensure firmware is patched regularly with support packages.
• Activate Firewall: Most routers come with a built-in firewall; ensure it’s activated correctly for an extra security layer. Enterprise solutions will require professionals to ensure the Firewall is set up correctly to protect your business.
• Use a VPN: Implement a VPN at the router level to encrypt all traffic, enhancing privacy and security.
• While hidden networks may still be detectable, following these guidelines will significantly enhance your WiFi security, protecting your devices and data effectively.
