Why Use a VPN for Public WiFi?

Public WiFi is nearly everywhere, but is it safe? Find out why you should use a VPN to secure your online experience on public WiFi.

November 14, 2023

When the internet is required for nearly anything, accessing public WiFi networks has become a common practice. 

Whether you're at a coffee shop, airport, or hotel, free WiFi seems like a convenient blessing. However, beneath the convenience lurks hidden dangers that can compromise your online security and privacy. 

This is where a Virtual Private Network (VPN) comes to the rescue. In this guide, we'll explore why using Mysterium VPN for public WiFi is not just a good idea; it's essential.

Identity Shielding

Protecting your identity is a fundamental reason to use a VPN, especially when connecting to public WiFi networks. Identity theft and online profiling are serious concerns in the digital age, and a VPN serves as a shield against these threats. Here's an in-depth exploration of why safeguarding your identity matters and how a VPN accomplishes this.

Concealing Your Real IP Address: Every device connected to the internet is assigned a unique IP address. This address can be used to track your online activities, pinpoint your geographical location, and even identify you personally. A VPN reroutes your internet traffic through a remote server in a different location. 

As a result, your actual IP address is concealed. Anyone attempting to trace your online actions will only see the IP address of the VPN service that hosts the server, effectively masking your identity.

Protection from Profiling: Online advertisers, marketers, and data brokers often engage in profiling, where they collect information about your online behavior and preferences. This data is then used to create targeted advertisements. 

By masking your IP address with a VPN, you disrupt the ability of these entities to track and profile you accurately. Your online activities become anonymous, making it harder for advertisers to create intrusive, personalized ads.

Protection Against Doxxing: Doxxing is the malicious act of revealing someone's private and personal information online, often with the intent of causing harm or harassment. By hiding your real IP address and making it difficult to trace your online activities back to you, a VPN reduces the risk of falling victim to doxxing attempts.

Enhanced Anonymity: When your real IP address is hidden, it becomes significantly more challenging for third parties to connect your online actions to your real-world identity. This enhanced anonymity provides an extra layer of security and privacy.

Avoiding Targeted Cyberattacks: Cybercriminals may use your IP address to identify potential targets for cyberattacks, such as phishing or malware distribution. By obfuscating your real IP with a VPN, you reduce the chances of being singled out for such attacks.

Protecting Personal and Financial Information: Identity theft involves stealing personal information to commit fraudulent activities. When your real IP address is hidden, cybercriminals cannot easily gather the information needed for identity theft, such as your location, browsing habits, or online interactions. This protection extends to safeguarding financial details, ensuring that your credit card information and banking activities remain private and secure.

Data Protection

Public WiFi networks, while convenient, are often a playground for cybercriminals seeking to exploit unsuspecting users. When you connect to these networks without a VPN, your data is at risk of interception. Here's a closer look at why protecting your data with Mysterium VPN on public WiFi hotspots is paramount.


  • Encryption is the cornerstone of data protection in the digital age, and it lies at the heart of why using a VPN for public WiFi is absolutely essential. Encryption is like a secret language that only you and the VPN server understand. When you send data over a public WiFi network with Mysterium VPN, it's first scrambled into an indecipherable code. This scrambling process ensures that even if a hacker manages to intercept your data packets, they will see nothing but a jumble of characters that make no sense without the decryption key.
  • Public WiFi networks are typically open and unencrypted, meaning that data transmitted on them is often in plain text. This makes it a prime target for cybercriminals using packet-sniffing tools to intercept and collect your data. With a VPN in place, your data packets are encrypted before leaving your device, hence, even if the data is intercepted, it will appear scrambled and unreadable to the cybercriminal. This robust protection extends to all your online activities, be it browsing, online banking, or sending emails.
  • A VPN connection establishes a secure, virtual tunnel between your device and its server. This tunnel is heavily encrypted, creating a secure conduit for your data to travel. Think of this tunnel as a direct and well-guarded path. Any data traveling through it is shielded from potential threats lurking on the public WiFi network, ensuring your information's safe arrival at its destination.
  • Encryption guarantees the confidentiality of your data. It means that your sensitive information, such as login credentials, credit card numbers, and personal messages, remains private and protected. Even if a cybercriminal gains access to your data, they'll only see an unreadable mess, rendering their efforts futile without the encryption keys held by your VPN and your device.
  • Many reputable VPN services such as Mysterium VPN use military-grade encryption standards, such as AES (Advanced Encryption Standard) with 1024-bit keys. This level of encryption is considered virtually unbreakable and is used by governments and corporations worldwide to safeguard their sensitive data. This level of security ensures that your data remains safe and sound, regardless of the skill level or intentions of potential attackers.
  • Encryption provided by a VPN isn't limited to specific types of data or online activities. It offers full-spectrum protection for everything you do online, whether it's browsing, online shopping or conducting business. This comprehensive safeguard ensures that all your digital interactions on public WiFi networks are shielded from prying eyes, guaranteeing your online privacy and security.

In summary, encryption is the armor that shields your data from the perils of public WiFi networks. It transforms your information into an unreadable code, ensuring that even if a cybercriminal attempts to intercept it, they are met with an impenetrable barrier. With encryption as your ally, you can confidently use public WiFi while keeping your sensitive information safe and secure.

Confidential Information

The protection of confidential information is a paramount concern when using public WiFi, and it's one of the key reasons why incorporating a VPN into your online routine is imperative. 

Let's delve deeper into the significance of safeguarding confidential data and how a VPN accomplishes this:

  • Confidential information often includes login credentials for various online accounts, including email, social media, and banking. These credentials are prime targets for cybercriminals. Without Mysterium VPN, when you connect to a public WiFi network, these credentials can be intercepted by hackers. They can use this information to gain unauthorized access to your accounts or engage in identity theft. With a VPN in place, your login credentials are encrypted and kept secure during transmission. This means that even if a hacker tries to intercept them, they remain unintelligible and useless.
  • When conducting financial transactions, such as online banking or making purchases, you inevitably share sensitive financial information, including credit card numbers and billing details. Public WiFi networks are not inherently secure, and hackers can exploit vulnerabilities to capture your financial data. Mysterium VPN encrypts this data, making it inaccessible to anyone attempting to eavesdrop on your connection. This ensures that your financial details are safeguarded, and your transactions remain confidential.
  • Personal and private messages exchanged over messaging apps, email, or other communication platforms contain confidential information. This can include personal conversations, sensitive business discussions, or valuable information. Mysterium VPN ensures that these messages are encrypted during transit. Even if a cybercriminal attempts to intercept your messages, they won't be able to decipher the content, preserving your privacy and the confidentiality of your conversations.
  • Your device may contain sensitive files, documents, or photos that you don't want falling into the wrong hands. When connected to public WiFi without a VPN, these files could be at risk. A VPN extends its protection to these files, ensuring that they remain encrypted and secure, even if someone tries to compromise your device's security.
  • When you're connected to a public WiFi network, you're essentially sharing a connection with other users, some of whom may have malicious intent. Without Mysterium VPN, your confidential information is exposed to anyone else on the same network. A VPN establishes a secure, private tunnel for your data, segregating it from the prying eyes of others on the network. This isolation ensures that your confidential information stays confidential.
  • Above all, protecting confidential information with a VPN provides peace of mind. You can conduct your online activities, whether they involve sensitive emails, financial transactions, or personal messages, without constantly worrying about data breaches or identity theft. This peace of mind allows you to focus on your tasks and interactions, knowing that your confidential information is under a reliable layer of protection.

In summary, the "Confidential Information" aspect of using a VPN on public WiFi is not just about safeguarding data; it's about preserving your digital privacy and maintaining control over your personal and sensitive information. A VPN adds an extra layer of protection and you can confidently engage in online activities, knowing that your confidential data is shielded from potential threats on public WiFi networks.


Eavesdropping, a nefarious practice where cybercriminals intercept and listen in on your online communication, poses a significant threat when using public WiFi. A VPN is your stalwart ally in thwarting eavesdroppers and ensuring that your conversations and sensitive information remain private. Here's why preventing eavesdropping is crucial and how a VPN achieves this:

  • Whether you're engaging in personal chats with friends and family or discussing sensitive matters with colleagues or clients, these conversations deserve privacy. Public WiFi networks, which are often open and unencrypted, provide an opportunity for eavesdroppers to intercept your conversations. A VPN encrypts your communication, rendering it unintelligible to anyone attempting to listen in.
  • If you're conducting business over public WiFi, discussing strategies, sharing proprietary information, or negotiating deals, the stakes are high. Eavesdropping on business communications can lead to data leaks, intellectual property theft, and financial losses. A VPN ensures that your business discussions remain confidential, preserving your organization's competitive edge.
  • Personal Identifiable Information (PII), such as your name, address, social security number, or healthcare details, is a prime target for identity thieves. Eavesdroppers on public WiFi networks can capture this information as it travels between your device and online services. With a VPN, your PII is enveloped in encryption, making it inaccessible to malicious actors.
  • Your web browsing habits, including the websites you visit and the content you access, are sensitive pieces of information. Advertisers, ISPs, and government agencies often track this data. A VPN shields your browsing history from prying eyes by routing your connection through a secure VPN server. This ensures that your online behavior remains private, and no one can monitor your web activities.
  • Eavesdropping often goes hand-in-hand with Man-in-the-Middle (MitM) attacks, where an attacker intercepts and alters communication between two parties. A VPN creates a secure tunnel that prevents MitM attacks. Even if an attacker attempts to intercept your communication, they won't be able to modify it without detection.
  • In an era of increasing digital surveillance and data collection, preserving online privacy is of paramount importance. Eavesdropping can lead to the erosion of this privacy. A VPN acts as a shield against unwanted surveillance, ensuring that your online activities remain confidential and your personal information remains out of the hands of data collectors.

In essence, preventing eavesdropping is synonymous with preserving your digital privacy and maintaining control over your sensitive information. By using a VPN on public WiFi hotspot, you're taking proactive steps to ensure that your conversations and data remain private, even on potentially insecure networks. This not only safeguards your personal and professional interests but also upholds your fundamental right to online privacy in an increasingly interconnected world.

Safeguarding Personal Files

Even if someone gains access to your device, the encrypted files are virtually impossible to open without the decryption keys held by the VPN.
  • Personal photos and videos capture cherished memories and moments. Losing access to these files due to theft or unauthorized access can be emotionally distressing. A VPN ensures that your personal memories remain protected, guaranteeing that no one can tamper with or steal these irreplaceable files.
  • If your device contains work-related files, sensitive documents, or proprietary information, these assets need rigorous protection. A VPN creates an additional layer of security, shielding these files from prying eyes, whether you're accessing them remotely or storing them locally.
  • In public WiFi environments, the risk of unauthorized intrusion into your device can be heightened. Cybercriminals may attempt to exploit vulnerabilities in your device's security. A VPN acts as a formidable defense, ensuring that even if an intrusion occurs, the data remains impenetrable due to encryption.
  • Your personal files reflect your digital life and history. Protecting them is an integral part of preserving your online privacy. A VPN extends privacy to every aspect of your online presence, including the files you store on your device. This comprehensive approach ensures that your entire digital footprint remains confidential.
  • Many individuals rely on cloud storage and file synchronization services to back up and access their personal files. A VPN enhances the security of these services by encrypting the data in transit. This means that even when you're syncing or accessing files remotely, your personal data remains shielded from potential interception.

Safeguarding personal files is not just about data protection; it's about preserving your digital life and ensuring that your memories, documents, and sensitive information remain secure.

Shielding Browsing History

Shielding your browsing history from prying eyes is a crucial aspect of maintaining your online privacy and security, particularly when using public WiFi networks. Here's an in-depth look at why this matters and how a VPN plays a pivotal role in this endeavor:

  • Your browsing history is a digital trail that reveals your online habits, interests, and preferences. It encompasses the websites you visit, the content you access, and the searches you perform. This information can be exploited by advertisers, ISPs, or even malicious actors to profile you, track your online behavior, and potentially target you with ads, or worse.
  • Internet Service Providers (ISPs) often have the capability to monitor and record your online activities, including your browsing history. In some regions, government agencies also engage in surveillance. A VPN encrypts your internet traffic, preventing your internet service provider and any potential surveillance entity from tracking and monitoring your browsing history. Your online activities become private and inaccessible to external parties.
  • Online advertisers frequently collect data from your browsing history to create targeted ads. The more they know about your interests and habits, the more personalized and invasive their ads can become. By using a VPN, you keep your browsing history hidden. Advertisers can't track your online activities, and you won't be subjected to overly invasive or targeted advertisements.
  • Some websites, apps, and platforms can be unavailable while traveling to certain countries. This can be frustrating when you need to access your banking, messaging, social media and subscription accounts. A VPN allows you to connect to servers in your home country, so you’re not stuck without your regular tools and resources  If you're conducting research or accessing sensitive information online, you may not want your searches and interests to be tracked or associated with your identity. A VPN ensures that your research remains private, shielding your browsing history and queries from prying eyes.
  • A VPN doesn't selectively protect certain aspects of your online presence; it offers comprehensive privacy protection. This includes safeguarding your browsing history, and ensuring that all your online activities remain confidential.
  • When you use a VPN, you regain the freedom to explore the internet without fear of being tracked or monitored. You can access websites, seek information, and engage in online activities without leaving a digital trail.

All in all, the "Shielding Browsing History" aspect of using a VPN for public WiFi is about reclaiming your online privacy. It's the digital equivalent of drawing a curtain to shield your activities from prying eyes.
