Public Wi-Fi has become a part of everyday life. We connect to it at coffee shops, airports, hotels, libraries, and even in city centers. It’s fast, it’s free, and it’s convenient — but it’s also one of the riskiest ways to get online. Without proper protection, using public Wi-Fi can expose your personal information to hackers, data thieves, and malicious actors.
This is where a reliable VPN comes in. For many, Surfshark VPN has become a preferred choice for securing connections on public networks. Its combination of strong encryption, privacy features, and ease of use makes it especially well-suited for protecting data when you’re away from your home network.
In this guide, we’ll explain why public Wi-Fi is dangerous, how Surfshark VPN works to protect you, and how to use it effectively every time you connect to an open network.
Public Wi-Fi networks are often unencrypted, meaning the data traveling between your device and the router can be intercepted. This opens the door to several security threats:
Man-in-the-Middle Attacks – Hackers position themselves between you and the connection, capturing your data as it’s sent.
Evil Twin Networks – Fraudulent hotspots created to look like legitimate public Wi-Fi.
Packet Sniffing – Cybercriminals use software to monitor and log network traffic.
Unencrypted Websites – Without HTTPS, your transmitted data can be read in plain text.
Session Hijacking – Attackers steal your session cookies to access your accounts without needing your password.
While some public networks do use basic security measures, they are rarely enough to guarantee privacy. This is why extra protection like Surfshark VPN is essential.
A VPN, or Virtual Private Network, encrypts your internet traffic and routes it through a secure server. With Surfshark, that means:
AES-256 Encryption – Your data is scrambled into unreadable code, even if intercepted.
IP Address Masking – Your real IP is hidden, replaced by the VPN server’s address.
Private DNS – Prevents DNS leaks that could reveal your browsing history.
Kill Switch – Cuts your internet connection if the VPN drops unexpectedly, preventing unprotected traffic.
Camouflage Mode – Hides the fact that you’re using a VPN, useful in restrictive networks.
NoBorders Mode – Lets you connect even in regions where VPNs are blocked.
Together, these features make it extremely difficult for anyone on the same public network to spy on your activity or steal your information.
Before heading out and connecting to open networks, take a few minutes to set up Surfshark properly:
Install the App – Available for iOS, Android, Windows, and macOS.
Sign In – Use your account credentials or create a new account.
Allow VPN Configuration – On mobile devices, grant the necessary permissions.
Enable Auto-Connect on Unsecured Networks – Found in Surfshark’s settings, this ensures you’re protected automatically.
Activate Kill Switch – Adds a safety net if the VPN disconnects unexpectedly.
Choose a Nearby Server – For best speed and stability, pick a server close to your physical location.
Once set up, Surfshark will encrypt your traffic whenever you connect to public Wi-Fi, without you having to remember to turn it on.
Public Wi-Fi is everywhere, but so are the risks. Here’s how Surfshark can protect you in common scenarios:
Travelers often use airport Wi-Fi for boarding passes, flight updates, and email. This is prime territory for hackers looking to grab personal data.
Surfshark Advantage: Encrypts all traffic and masks your IP, keeping both work and personal accounts safe.
Cafes are popular remote work spots, but their networks are typically open and unsecured.
Surfshark Advantage: Blocks snooping attempts, hides browsing activity from other users, and prevents potential data theft.
Hotel Wi-Fi often uses a shared password for all guests, making it easy for anyone connected to scan traffic.
Surfshark Advantage: Ensures your activity remains invisible to other guests and hotel network administrators.
Free Wi-Fi in parks, libraries, and city centers is often completely open.
Surfshark Advantage: Encrypts all online activity, preventing packet sniffing and other data interception methods.
While Surfshark works well with default settings, you can make it even more effective for public network use:
Use WireGuard Protocol – Balances speed and security, ideal for mobile and unstable connections.
Turn On CleanWeb – Blocks ads, trackers, and malicious links while you browse.
Enable MultiHop for Sensitive Work – Routes your traffic through two different servers for extra privacy.
Connect Before Opening Apps – Start Surfshark before logging into any accounts or loading web pages.
These tweaks help ensure you’re always getting the best mix of protection and performance.
A common concern with VPNs is speed reduction. On public Wi-Fi, you’re often dealing with shared bandwidth, so any slowdown is more noticeable. Surfshark minimizes this by:
Operating high-speed servers in over 100 locations
Using modern protocols like WireGuard for efficiency
Offering smart server selection to connect you to the fastest available option
In most real-world use, browsing, streaming, and messaging remain smooth even when connected through a VPN.
When using public Wi-Fi, losing VPN protection even for a few seconds can expose sensitive data. Surfshark’s Kill Switch feature acts as a failsafe — if the VPN connection drops, it blocks all internet traffic until the secure connection is restored.
This is particularly important when:
Sending work emails with attachments
Logging into online banking
Accessing private accounts while traveling
When you’re using a VPN on an untrusted network, you want to be sure the VPN itself isn’t keeping records of your activity. Surfshark operates under a strict no-logs policy, meaning it does not store browsing history, connection timestamps, or IP addresses. Combined with encryption, this means even if someone attempted to request your data from Surfshark, there would be nothing to hand over.
Even with a strong VPN like Surfshark, there are extra measures you can take to maximize safety when connected to public networks.
Avoid logging into sensitive accounts unless necessary – Even though your connection is encrypted, limiting exposure reduces risk.
Disable file sharing – Turn off AirDrop on iOS and file sharing on laptops before joining public Wi-Fi.
Use HTTPS websites – Look for the padlock icon in your browser; this adds another layer of encryption on top of your VPN.
Regularly update your Surfshark app – Updates often include security patches and performance improvements.
Pair VPN use with antivirus software – This provides protection from malicious downloads and phishing attempts.
By combining these habits with Surfshark’s encryption, you create a strong defense against most Wi-Fi threats.
Travelers are among the most at-risk users of public Wi-Fi. From checking in online to accessing maps and translation tools, they often rely on networks that are completely unsecured.
Benefits for travelers using Surfshark:
Access to home services – Connect to your home country server to use familiar banking or streaming accounts.
Avoid location-based censorship – Bypass blocked apps or websites in certain countries.
Safe bookings – Secure hotel, flight, and activity reservations without exposing payment details.
Privacy in airports and transit hubs – These are prime locations for data interception attempts.
Surfshark’s NoBorders and Camouflage modes are especially useful here, ensuring a VPN connection works smoothly even in regions with internet restrictions.
Public Wi-Fi is often used for streaming — in airports while waiting for a flight, in hotels during downtime, or in cafés while relaxing. Surfshark makes this safer by encrypting your traffic, but it also helps with accessibility:
Unblock region-locked content – Stream from your home country’s catalog.
Prevent throttling – ISPs sometimes slow streaming speeds on public networks; a VPN can mask your activity to avoid this.
Maintain smooth playback – Choose a server close to the streaming service’s location for best performance.
The ability to protect your privacy without sacrificing entertainment is a big advantage for travelers and commuters alike.
There’s a lot of misinformation about VPNs, especially when it comes to their use on open networks. Here are some clarifications:
Myth 1: “Public Wi-Fi is safe if it requires a password.”
Reality: Shared passwords don’t encrypt traffic between devices, meaning others on the network can still see your data.
Myth 2: “Apple or Android devices don’t need VPNs.”
Reality: While mobile operating systems have strong security, they can’t encrypt your internet traffic by themselves.
Myth 3: “VPNs make the internet too slow to use.”
Reality: With modern protocols like WireGuard and high-speed servers, the difference in speed is often minimal.
For most users, the default Surfshark configuration works fine, but these settings are worth enabling for maximum safety on public networks:
Auto-connect on Wi-Fi – Ensure the VPN activates every time you join a network.
Kill Switch – Essential for uninterrupted protection.
CleanWeb – Reduces the risk of clicking on malicious links.
WireGuard protocol – Offers the best balance of speed and security on mobile.
These settings make Surfshark a “set it and forget it” tool, so you never accidentally browse unprotected.
Q: Can I use Surfshark on multiple devices in a café or airport?
A: Yes. Surfshark allows unlimited device connections, so you can protect your phone, tablet, and laptop at the same time.
Q: Does Surfshark protect me if I connect to a fake hotspot?
A: It can prevent your data from being read, but you should still avoid suspicious networks and confirm network names with staff.
Q: Will Surfshark stop malware from public Wi-Fi?
A: While CleanWeb blocks malicious sites, a VPN alone isn’t a replacement for antivirus software.

Q: Does using Surfshark on public Wi-Fi hide my location?
A: Yes. Your IP address is replaced with that of the VPN server, making your real location harder to determine.
Public Wi-Fi can be a useful tool, but it comes with risks that too many people overlook. Without encryption, your personal data, browsing activity, and even login credentials can be intercepted in seconds. Surfshark VPN provides a simple yet powerful way to protect yourself, combining military-grade encryption, a no-logs policy, and features designed specifically for security in untrusted environments.
By enabling Surfshark before connecting to public networks, you take control of your privacy and greatly reduce the chances of falling victim to cyber threats.
