Which is The Best Networks Between Public & Private Networks?

Hello!

You may need to switch from a public network service to a private one for several reasons. Privacy and security are usually at the top of the list. Before making the change, it helps to understand the key differences between public and private networks.

Key Differences Between Public and Private Networks

As the name suggests, a public network is open to anyone. Classic examples include free Wi-Fi in cafés, airports or libraries, as well as the internet itself.

Private networks, by contrast, restrict access. They are commonly found in homes, offices and schools, where only authorised devices can connect. This controlled environment makes it easier to protect sensitive data and manage internal resources.

Additional Technical and Security Distinctions

• Public networks require extra caution with device addressing and visibility.
• Private networks offer greater flexibility in IP addressing and device management.
• Neither network type is tied to a single topology; the main differences lie in how security and access rules are configured.

Common Uses of Private Networks

If you are considering moving to a private network, it is useful to know where such networks are typically deployed. Here are the most frequent scenarios:

Office Networks

In corporate environments, private networks keep company devices and data away from unauthorised users while still allowing controlled internet access. Businesses rely on them to run internal applications, back-end services and to protect confidential information such as financial records.

Home and Critical Infrastructure Networks

At home, private Wi-Fi networks let family members share files, printers and other devices securely. Larger private networks also support critical infrastructure where nationally sensitive data must remain protected.

Private networks enable discovery features that make file sharing and peripheral access simple. On public networks these features are disabled by default. Windows 10, for example, automatically turns discovery off when you connect to a public Wi-Fi hotspot.

Customising Discovery and Firewall Settings

Switching from public to private involves adjusting network discovery and firewall rules. Below are the steps for Windows 10.

Discovery Settings

To change discovery options:

• Click the Start Menu and type “Control Panel”.
• Open Network & Internet → View network status and tasks.
• Select “Change advanced sharing settings”.

Here you can enable or disable Network Discovery, Homegroup connections and File sharing according to your needs.

Firewall Settings

To adjust the firewall:

• Open Control Panel → System and Security → Windows Firewall.
• Choose “Allow an app or feature through Windows Firewall” to fine-tune rules for specific applications.

Changing the Network Profile

Follow these steps to switch the network type:

1. Open Settings → Network & Internet.
2. Under Wi-Fi or Ethernet, click the connected network.
3. Select “Private” as the network profile.

Once the profile is private, you can create a Homegroup or adjust sharing options in Advanced sharing settings.

Private networks give you full control over security policies and device visibility. With Windows 10 these adjustments are straightforward and require only basic technical knowledge.
