What makes a VPN secure?

Industry-leading encryption

A VPN (Virtual Private Network) with strong encryption protects your data from being read or intercepted by third parties. A secure VPN uses industry-standard encryption, such as AES-256 or ChaCha20, to scramble your internet traffic so that even if it’s intercepted, it remains unreadable.

Verified no-logs policy

A reputable VPN doesn’t track or store users’ online activity. An independently verified no-logs VPN service has proven that it doesn’t keep usage logs — ensuring no activity tracking and no data to hand over.

Modern VPN protocols

VPN protocols define how your data is authenticated, encrypted, and transmitted — essentially, how a VPN works. A secure VPN should support modern, industry-standard protocols designed for strong security, reliability, and performance: WireGuard, IKEv2, and OpenVPN.

How a secure VPN protects you from online threats

Once you purchase a subscription, download a VPN app, and hit Connect, here’s what a secure VPN does:

Your device connects to the VPN provider’s server with specified credentials.
The server authenticates the credentials.
Your VPN app sets up a tunneled connection to the server and manages the encryption.
Your device establishes and maintains a secure VPN connection.

When you turn on the VPN, two things happen: your IP (Internet Protocol) address is replaced with the IP of the server, and all your internet traffic is encrypted.

Now that the app and the VPN server have an agreed-upon cipher, as you browse, every bit of data is encrypted before it reaches your ISP (Internet Service Provider). When the data reaches the VPN server, it gets decrypted. This process keeps your internet connection more secure and private.

No-logs policy

Your browsing habits are your business, which is why Surfshark never tracks, collects, or shares your activity. Our no-logs policy has been independently verified by Deloitte, ensuring total transparency.

Jurisdiction

Based in the Netherlands, Surfshark operates in a favorable legal environment with no mandatory data retention laws. This jurisdiction allows us to uphold our strict no-logs policy with no interference.

Obfuscation

Obfuscation hides your data and makes it much harder to identify that you’re using a VPN. This technology helps you browse freely even in places that highly restrict internet usage.

RAM-only servers

Surfshark’s entire network runs on diskless, RAM-only servers that automatically wipe all data with every reboot. This hardware-level security ensures that no information can ever be physically retrieved from our servers.

Kill switch

Protect your data from accidental exposure with a kill switch — an automatic safety net that cuts your internet if the VPN connection drops. This ensures no unencrypted data leaves your device.

Double VPN

Boost your protection online by routing your traffic through two different VPN servers at once with Multi Hop. This process encrypts your connection twice, making it virtually impossible for anyone to trace your digital footprint.

Everlink

Experience a self-healing connection with Surfshark’s patented Everlink infrastructure that keeps your VPN stable. If a server requires maintenance, Everlink seamlessly switches you to a new one without interrupting your session.

DNS leak protection

Surfshark routes all your DNS (Domain Name System) requests through private, encrypted tunnels. This prevents Wi-Fi eavesdropping and your ISP from seeing which websites you visit, ensuring your browsing history stays private.

Split tunneling

Use Bypasser, Surfshark’s VPN split tunneling, to choose which apps and websites need VPN protection and which can access the internet directly without encryption — perfect for IP-sensitive services.

Rotating IP

Stay ahead of trackers by automatically changing your IP address every few minutes without disconnecting. This constant IP rotation makes it much harder for advertisers and data brokers to profile your online behavior.

Multi IP

Available on macOS devices, Multi IP prevents cross-site tracking and ensures your activities cannot be linked together by assigning a unique, separate IP address to every website or app you use during a single session.

More than a VPN

Get a complete cybersecurity suite including a built-in ad blocker, antivirus, and identity masking tools. From blocking malware to generating an alternative persona, Surfshark takes protecting your digital presence to another level.

3 VPN myths debunked

MYTH: All VPNs offer the same level of security.	FACT: VPN security varies dramatically between providers. Free VPNs often have weak encryption, log your data, and even sell your information. Only independently audited VPNs like Surfshark can prove their security claims.
MYTH: A VPN makes you 100% anonymous online.	FACT: Complete anonymity online is generally not possible. VPN security protects your connection and hides your IP address, significantly enhancing privacy. However, VPNs aren’t magic — if you log into Facebook while using a VPN, Facebook still knows it’s you.
MYTH: Free VPNs are just as secure as paid ones.	FACT: Free VPNs are often dangerous. Studies show that nearly two-thirds of free VPN apps have privacy issues. They typically make money by selling your data, injecting ads, or installing malware. Paid VPNs like Surfshark invest in VPN security infrastructure.

Are free VPNs secure?

Free VPNs often compromise on privacy and performance. Surfshark VPN offers a more secure and reliable browsing experience you can trust.

	Free VPNs	Surfshark VPN
Data collection risk	High: free options often log browsing history and sell data to third parties	Low: Surfshark’s strict no-logs policy is independently verified
Speed and bandwidth	Restricted: speed throttling and bandwidth caps are common	Unlimited: no bandwidth or speed restrictions are in place
Ads and trackers	Common: free tools may inject ads or allow trackers	Blocked: Clean Web offers built-in ad and tracker blocking
Customer support	Limited: usually lack live help and have slow response times	24/7: email and live chat support are available
VPN server locations	Few: frequently have congested servers that slow your connection	Thousands: lets you connect to 4,500+ high-speed servers in 100 countries
Encryption	Unreliable: may lack secure encryption protocols	Strong: robust encryption provides increased privacy protection

The risk of data exposure

According to Surfshark research, over 425.7 million online accounts worldwide were breached in 2025 alone — that’s 800+ account breaches every minute.

The 10 countries most impacted by data breaches account for 65% of all compromised accounts worldwide. The United States leads by a wide margin with 142.9 million breached accounts, followed by France and India, while Germany, Russia, the UK, Canada, Vietnam, Brazil, and Spain complete the top 10.

Each breach highlights how vulnerable online information can be without proper protection. Using a VPN encrypts your internet traffic, shielding your data from hackers, even when networks are compromised.

Why do you need a secure VPN?

Use public Wi-Fi safely

Free public Wi-Fi often isn’t secure, and hackers can easily compromise such Wi-Fi networks. If you connect to a fake or compromised hotspot, you risk sharing your credentials, log-ins, and credit card info. A VPN will encrypt your data before it leaves your device, making it useless to the hotspot hacker.

Avoid censorship

Countries where governments censor the internet often target and block VPN traffic, too, which could infringe on your right to freedom of speech and expression. A VPN with obfuscated servers changes how your VPN data appears to network filters and makes it harder for firewalls to detect and block your connection.

Protect personal data from snoopers

Your online activity can be collected and analyzed by data brokers, internet providers, and the government, often for operational, commercial, or legal purposes. A VPN encrypts your internet traffic, so no snoops or extra eyes can spy on your online activities.

Access home entertainment

Some internet content may not be available in certain regions. Don’t lose access to your favorite content when traveling — connect to a VPN server in your country and browse as if you were back home, with easier access to regional media and sites.

Remove bandwidth throttling

Your ISP can slow down your connection if you’re streaming shows or downloading files. Connect to a VPN to binge your favorite series in the privacy of your home without activity-based internet throttling.

Disclaimer: Please note that using Surfshark services for any illegal activities is strictly forbidden and violates our Terms of Service. Make sure that any use of Surfshark services for your particular activities conforms to all relevant laws and regulations, including those of any service providers and websites you access using Surfshark.

FAQ

Is Surfshark VPN safe?

Yes, Surfshark VPN is safe. Surfshark uses only industry-leading VPN protocols and encryption algorithms to ensure security and privacy. Surfshark also doesn’t log your activities online and has passed multiple independent audits to prove the legitimacy of its services.

What are the security risks of a VPN?

Common VPN security issues are mostly related to free VPN providers and data leaks. Some free VPN services aren’t transparent about collecting user data and are known to sell or leak user data. So, it’s best to pick a reputable paid VPN provider to avoid such risks.

Does using a VPN look suspicious?

No — people use VPNs every day for routine tasks like securing public Wi-Fi, protecting personal data, or accessing work networks. Privacy is a fundamental digital right, and using a VPN is legal in most parts of the world.

However, using the Tor browser with a VPN may attract attention from your ISP because of Tor’s association with the dark web.

Am I safe from hackers while using a VPN?

Thanks to a VPN, you are safe from many forms of hacking. But remember that if you click a malicious link and download a virus or other malware, a VPN won’t help you. A VPN only protects your online connection.

How do I make sure my VPN is secure?

To test if your VPN is working, go to what is my IP and check whether the current IP address differs from your original one. To see if your VPN works securely, you can check if it’s leaking your data by doing a DNS or WebRTC leak test.

Do I need a VPN if I use HTTPS?

Yes. While HTTPS encrypts the content of your activity on a specific website, it does not hide the fact that you are visiting that site from your ISP or network provider. A VPN provides an additional layer of privacy by masking your IP address and entire browsing history from third parties.
