In today’s digital age, WiFi has become an essential part of our daily lives. We use it to stay connected with friends and family, access important information, and even control our smart home devices. However, have you ever noticed that sometimes your browser warns you that the WiFi network you’re connected to is “not secure”? What does this mean, and how can you protect yourself from potential threats?
Understanding the Basics of WiFi Security
Before we dive into the concept of “not secure” WiFi, let’s take a step back and understand how WiFi security works. WiFi networks use encryption protocols to secure data transmission between devices. The most common encryption protocols used are WEP, WPA, and WPA2. WPA2 is the most secure protocol, but it’s being phased out in favor of WPA3, which offers even stronger security features.
When you connect to a WiFi network, your device and the router establish a secure connection using the encryption protocol. This ensures that any data transmitted between your device and the router is encrypted and protected from interception.
What Does “Not Secure” WiFi Mean?
Now, let’s get back to the topic at hand. When your browser warns you that the WiFi network you’re connected to is “not secure,” it means that the network is using an outdated or insecure encryption protocol. This can put your data at risk of being intercepted by hackers.
There are several reasons why a WiFi network might be considered “not secure”:
- Outdated encryption protocol: If the network is using an outdated encryption protocol like WEP or WPA, it may not provide adequate security.
- No encryption: If the network is not using any encryption protocol, data transmission is not secure.
- Weak password: If the network password is weak or easily guessable, it can be compromised by hackers.
- Public network: Public WiFi networks, like those found in coffee shops or airports, are often not secure because they’re open to anyone.

What does “Not Secure” WiFi mean?
“Not Secure” WiFi refers to a type of internet connection that does not use encryption to protect data transmitted between your device and the WiFi router. This means that any data you send or receive over this connection, including sensitive information like passwords and credit card numbers, can be intercepted and read by others.
When you connect to a “Not Secure” WiFi network, your device will typically display a warning message indicating that the connection is not secure. This is because the WiFi network is using an outdated or insecure protocol, such as WEP (Wired Equivalent Privacy) or an open network without a password. To stay safe, it’s recommended to avoid using public WiFi networks that are not secure, especially when accessing sensitive information.
How does “Not Secure” WiFi put me at risk?
“Not Secure” WiFi puts you at risk of data theft and eavesdropping. When you connect to an unsecured WiFi network, hackers can easily intercept your data using specialized software. This means that they can steal sensitive information like passwords, credit card numbers, and personal data. Additionally, hackers can also use unsecured WiFi networks to spread malware and viruses to your device.
To protect yourself from these risks, it’s essential to use a virtual private network (VPN) when connecting to public WiFi networks. A VPN creates a secure and encrypted connection between your device and the internet, making it difficult for hackers to intercept your data. You should also avoid accessing sensitive information, like online banking or shopping, when connected to an unsecured WiFi network.
What are the common types of “Not Secure” WiFi networks?
There are several types of “Not Secure” WiFi networks, including open networks without a password, WEP (Wired Equivalent Privacy) networks, and WPA (WiFi Protected Access) networks with a weak password. Open networks without a password are the most vulnerable to hacking, as anyone can connect to them without needing a password.
WEP networks are also insecure, as the encryption protocol used is outdated and can be easily hacked. WPA networks with a weak password are also vulnerable to hacking, as hackers can use specialized software to guess the password. To stay safe, it’s recommended to use a WPA2 (WiFi Protected Access 2) or WPA3 network with a strong password.
How can I identify a “Not Secure” WiFi network?
You can identify a “Not Secure” WiFi network by looking for the following signs: the network is open and does not require a password, the network uses WEP or WPA with a weak password, or your device displays a warning message indicating that the connection is not secure.
