Many people use public Wifi today. While it may be exciting to get free internet, it may impose several security risks. This post explains in full detail all the security implications of public Wi-Fi connections and how to stay safe when using them.


Today’s world is overcrowded with microwave signals from public Wi-Fi hotspots. They’re everywhere. And yes, of course, we all love them. They have great practical value. However, forgetting how dangerous they are is easy because they are so helpful. Most of the dangers in public Wi-Fi public spots are easy to neutralize with a good VPN. The VPN is quickly becoming our modern world’s new Swiss Army Knife. This post will tell you about using a good Wifi VPN service (such as ExtremeVPN) to enhance your security so you can enjoy all your favorite Wi-Fi public spots without any significant risk.

Gaining Insight into the Security Measures Offered by VPNs


A VPN is your personal digital bodyguard when you go online in public. But how does it get you there? The main trick is encryption. Scambling all your data so it’s impossible to read by any external observer. By implementing robust encryption protocols, a VPN guarantees that even if unauthorized individuals manage to access your network connection, they will all encounter an incomprehensible mishmash of information. With a VPN, you can confidently explore the vast realm of the internet, seamlessly access your accounts, and engage in secure online transactions without compromising your valuable digital security.’

Ensuring Safety on Free Public Wi-Fi Networks with ExtremeVPN


You can’t argue with public Wi-Fi’s convenience. The thing is that they are as dangerous as they are practical. They usually lack encryption or any protection. That is why hackers are wrongdoers and are even happier with public Wi-Fi than regular users. The risks are actual and grievous. This post will show you some of the worst problems inherent to public Wi-Fi hotspots. Equally important, we will provide practical strategies to counteract these threats.

1. Man-in-the-Middle Attacks

In this malicious scheme, ill-intent individuals are in the middle of your connection to the websites or services you use. They aim to intercept your network traffic and clandestinely monitor your online activities. By doing so, they may acquire sensitive information like login credentials, financial details, and personal data. To safeguard your privacy and security, employing a VPN is essential. It encrypts your data, rendering it incomprehensible to these malicious actors, thereby providing an added layer of protection.

2. Evil Twin Attacks

Cybercriminals often set up rogue networks that mimic legitimate Wi-Fi hotspots to deceive unsuspecting users. Known as evil twin attacks, these networks trick individuals into connecting, giving the hackers unrestricted access to their data. You can establish a secure connection using a VPN even on these deceptive networks, rendering your data impervious to prying eyes.

Cookies, small packets of data stored on your device, play a crucial role in maintaining online sessions. When utilizing public Wi-Fi networks, malicious individuals can exploit these cookies to illicitly access your accounts and personal information. A VPN, by encrypting your data, thwarts these attackers from intercepting and manipulating your cookies, thereby ensuring the security of your online sessions.

4. Enhancing Security

Computer worms represent a distinct form of malicious software capable of infiltrating your device without user interaction. These worms exploit weaknesses in your device’s operating system or network protocols, thereby endangering your data and potentially increasing to other devices connected to the network. To fortify the security of your data, a VPN employs data encryption techniques, establishing an extra layer of safeguarding against these detrimental worms and guaranteeing the preservation of your information’s integrity.

5. Wi-Fi Pineapples

Wi-Fi pineapples are purposely designed to carry out network attacks. By masquerading as familiar Wi-Fi networks, they deceive unsuspecting users into connecting, enabling hackers to intercept and manipulate their data. A VPN establishes a secure tunnel between your device and the internet, effectively preventing Wi-Fi pineapples from accessing your data and safeguarding you from potential harm.

Risks of Using a Free VPN to Access LINE

Using public Wi-Fi networks without adequate protection exposes individuals to the risk of data theft, as eavesdroppers can monitor their network traffic. This puts personal information at risk, including:

  • Credit card and bank account details: Transmitting financial information over unsecured networks allows cybercriminals to intercept and gain access to sensitive financial data.
  • Social media passwords: Hackers can intercept login credentials for social media accounts, enabling unauthorized access to profiles and potential misuse.
  • Email login credentials: Cybercriminals can intercept email login details, granting them access to personal and professional communications.
  • Other personal information: Any data entered while connected to public Wi-Fi, such as addresses, phone numbers, and private messages, can be vulnerable to interception.

A VPN encrypts all activities to ensure data confidentiality and protection from prying eyes. Whether browsing social media, making online purchases, or accessing sensitive information, a VPN establishes a secure tunnel that shields data from potential threats.

Strengthening Security Measures on Public Wi-Fi Networks 

Stay Secure with the Best Encryption

While it may not always be feasible to avoid public Wi-Fi networks altogether, adopting certain precautions can significantly reduce security risks: 

  1. Prioritize a Trusted VPN: Select a reputable VPN provider renowned for its robust encryption protocols and reliable security features. Utilizing a VPN establishes a secure connection, encrypts your data, and effectively safeguards against prevalent threats commonly encountered on public Wi-Fi networks.
  2. Do not share any files: Your device’s file-sharing features should always be off when you’re online through a public Wi-Fi signal. This precludes unauthorized access to your toys, so the probability of a data breach decreases significantly.
  3. Deactivate Wi-Fi Auto-Connect: Cybercriminals often create deceptive networks with names similar to legitimate ones, enticing users to connect automatically. Safeguard against this by turning off the auto-connect feature on your device. Manually selecting trusted networks helps minimize the chances of inadvertently connecting to fraudulent networks.
  4. Exercise Caution with Login Credentials: If you are not employing a VPN, exercise utmost care when entering login details for your online accounts while connected to public Wi-Fi networks. Refrain from accessing sensitive accounts, such as online banking or email, unless you have confidence in the network’s security. By diligently implementing these proactive measures, you can fortify security and effectively mitigate potential risks associated with public Wi-Fi networks.

Public Wi-Fi Networks and VPN Connectivity

While it is uncommon, public Wi-Fi networks can block VPN connections. This restriction often occurs when network administrators intentionally limit VPN usage to monitor users’ online activities, raising concerns about privacy and surveillance.

Suppose your VPN connection is blocked on a public Wi-Fi network. In that case, you can try alternative methods to overcome this issue. Consider using different connection protocols or switching to alternate servers provided by your VPN service. These options help bypass potential VPN blocks and maintain the privacy and security of your data while using public Wi-Fi.

Can a Wi-Fi Network Block a VPN?


In principle, public Wi-Fi networks can block VPNs. However, it’s an unlikely event, and you will be able to bypass it in most cases. Several factors determine if such a block can happen, among them the network setup, the level of security measures, and the precise way the administrators manage the Wi-Fi access.

Let’s see the potential resources a Wi-Fi network has to block VPNs.

  • Deep Packet Inspection (DPI): Some public Wi-Fi networks use this technology to examine the data packets passing through the web. They can identify VPN traffic based on packet headers or other distinguishing characteristics and block or restrict VPN connections.
  • Port Blocking: Public Wi-Fi networks can block specific ports typically associated with VPN protocols. Let’s say your VPN uses port 1194 to channel the OpenVPN traffic. The network admin could block that port so your VPN can’t use it to create the OpenVPN tunnel.
  • NS Filtering: Public Wi-Fi networks can utilize DNS (Domain Name System) filtering to prevent VPN clients from resolving domain names associated with VPN servers. By blocking access to the VPN server’s domain names, they effectively hinder VPN connections.
  • IP Address Blocking: Public Wi-Fi networks can block specific IP addresses known to be associated with VPN servers. This method prevents devices from connecting with those VPN servers, blocking VPN access.
  • Application Filtering: Some networks use filtering or firewall rules to block VPN-related applications or protocols. They may identify VPN software or protocols and explicitly block them to prevent VPN usage.

While every public Wi-Fi network can potentially block VPNs, very few do. Moreover, suppose your VPN is premium (like ExtremeVPN). In that case, its app can deploy a strategy to bypass the block, such as obfuscation or a particular VPN protocol.

So, your favorite Wi-Fi hotspot is playing hard to get? No worries, try this:

  • Try another protocol: Using a different VPN tunnel (e.g., from OpenVPN to IKEv2 or WireGuard) may bypass certain network restrictions.
  • Pick another server: Attempt connecting to a different VPN server. The new server may be unknown to the Wi-Fi if it blocks known ones.
  • Use obfuscated servers: Some VPN providers offer servers to bypass VPN blocking. Obfuscation is one of the most powerful technologies in premium VPNs (it’s the bit of magic that makes them work from China when they do. The Wi-Fi network will see all your traffic as standard HTTPS, so it won’t raise any red flags.
  • Get a new VPN provider: This Wi-Fi you like so much already has the number of your current VPN provider. Get a new, better one. ExtremeVPN will hardly ever give you this problem.

Long story short: Wi-Fi networks can block VPNs, but they seldom do. And when that happens, if your service is of premium quality, you will have plenty of ways to overcome the block with any of the strategies we listed in this section.

Can a Public Wi-Fi Provider See My Browsing History?


Many users wonder how much of their activities can be monitored by the public Wi-Fi providers at any hotspot. In a standard, properly configured network, the provider should not be able to access your browsing history or anything else. However, we can only assume that some network administrators worldwide are as capable and decent, so having a little precaution is always a good idea.

Let’s take a minute to fully explore this scenario and the technical details that affect your browsing history’s visibility in a public Wi-Fi spot.

  • Encryption: Most websites are HTTPS these days. So, the traffic with them is encrypted, and it’s practically impossible for any external observer to figure out what you do on each website. Yes, they can know which pages you visit, but different from what you did with them. Of course, those few websites that still need to adopt HTTPS will generate traffic that the Wi-Fi provider could see. The important thing is that, by sheer force of numbers, it’s unlikely that your activity can be scrutinized in a Wi-Fi public network if only because most websites are HTTPS nowadays.
  • Transport Layer Security (TLS): This protocol was the substitute for SSL to establish safe links, and most websites currently use it. This protocol also prevents external eavesdroppers from monitoring you.
  • Domain Name System (DNS) Encryption: The DNS turns domain names into IP numbers. This is how your browser finds the webpage you want: it sends the domain name you type to a DNS server, which returns the correct IP address for that website. This process is a weak link in the security chain and is a frequent source of IP leaks in mediocre VPNs. If your traffic is not encrypted, then your DNS queries can reveal to your provider the websites you are visiting.
  • Virtual Private Network (VPN): A network that encrypts all your traffic and hides your IP address. As long as you are online through a premium VPN, nobody, including your Wi-Fi network admins, can figure out what you are doing online.

So, there is little chance that your Wi-Fi connection could betray your privacy. Most specifications in the current World Wide Web promote encryption and enhanced security, with DNS queries being the only problematic step in the process. And if you use a VPN, the probability goes to zero for practical purposes.

However, it’s essential to exercise caution as not all public Wi-Fi networks implement proper security measures or follow best practices. Malicious actors or poorly configured networks could intercept or monitor your browsing activity.

In the previous sections, we explained how to mind your security in public Wi-Fi networks. That’s all you need to know. Above everything else, the most important thing is always online through your VPN. In this way, the Wi-Fi provider will only see that you are connecting to a specific server on the internet but nothing about your browsing history or other activities. 

So the answer to this section’s question is simple. You have nothing to worry about if your VPN is online while connected to any public Wi-Fi hotspot.


Wireless internet links are here to stay. They are more critical for most internauts with every passing day, so it’s unrealistic to think we can manage the risks they involve by avoiding them. Instead, the thing to do is to learn about the resources available to ensure that every public Wi-Fi connection we enjoy poses no risk to our privacy, security, and anonymity. In this regard, premium VPNs are your best friend. If you don’t have one yet, you should get one immediately, especially if it’s ExtremeVPN.
