A secure VPN does more than just hide your IP address. It protects your data, resists tracking, and ensures that no one (not your ISP, your VPN provider, or third parties) can access your browsing activity. But not all VPNs are built with real security in mind.
This guide compares the 10 most secure VPNs for 2025, focusing on providers with strict no-logs policies, independent audits, strong encryption, and transparent privacy practices. Whether you’re working remotely, traveling, or just want full control over your connection, these are the VPNs that prioritize security without cutting corners.
Quick picks:
Best Overall: ExpressVPN – RAM-only servers, independent audits, Lightway protocol
Best Value: Surfshark – Affordable, secure, and supports unlimited devices
Best for Privacy: Mullvad – Anonymous signup and no personal data required
Why You Need a Secure VPN
Most people turn to VPNs for privacy, but few stop to ask how secure their VPN actually is. The truth is, many providers promise protection while quietly collecting user data, running outdated protocols, or failing to prevent DNS leaks. Others offer free access in exchange for tracking everything you do, essentially replacing one privacy risk with another.
A secure VPN doesn’t just mask your IP. It shields your internet traffic from interception on public Wi-Fi, blocks third-party tracking, and keeps your online activity out of reach from internet providers, ad networks, and even governments. For journalists, remote workers, or anyone dealing with sensitive information, this level of protection isn’t optional.
Equally important is what a secure VPN doesn’t do: it doesn’t log your browsing history, doesn’t store metadata that can be tied back to you, and doesn’t hide behind vague privacy policies. Features like diskless servers, strong encryption protocols, and regular security audits separate serious services from the rest.
Key Features to Look For in a Secure VPN
Not all VPNs are built the same. If privacy and security are your top concerns, there are a few non-negotiable features to look for. These are the signals that a VPN takes its role seriously, not just in how it markets itself, but in how it’s built and operated.
1. Independently Audited No-Logs Policy
A “no-logs” claim doesn’t mean much unless it’s verified. A trustworthy VPN should go through regular third-party audits and publish the results. These audits review how the provider handles user data, whether they store connection logs, and if their infrastructure matches what’s promised.
2. Secure Protocols Built for Speed and Privacy
Older protocols like PPTP or L2TP are outdated and vulnerable. Look for VPNs that use modern, open-source protocols like WireGuard, or well-maintained proprietary ones like Lightway (ExpressVPN) or NordLynx (NordVPN). These offer better encryption, faster performance, and fewer security flaws.
3. RAM-Only or Diskless Servers
VPNs that run on RAM-only infrastructure don’t write data to disk. Every time the server restarts, everything is wiped. This limits the exposure window in case of physical access or system compromise, a major improvement over traditional setups.
4. Reliable Kill Switch and Leak Protection
A good VPN should include a kill switch that blocks all traffic if the connection drops unexpectedly. It should also prevent DNS and IPv6 leaks, which can quietly reveal your real identity even if the VPN appears connected.
5. Jurisdiction Outside Surveillance Alliances
Where a VPN is headquartered matters. Providers based in countries outside the “14-Eyes” intelligence-sharing alliances (such as Switzerland or Panama) are under less pressure to retain or share user data with governments.
How We Selected the Top 10 Most Secure VPNs
This list focuses on VPNs that demonstrate real security, not just feature checklists or clever branding. We looked at providers with publicly audited no-logs policies, strong encryption standards, and infrastructure choices that reduce the risk of data exposure.
We prioritized services that have been independently tested, operate RAM-only servers, and maintain a clear jurisdictional stance when it comes to privacy laws. We also considered whether key technologies – like kill switches, leak protection, and modern VPN protocols – are enabled by default rather than buried in settings.
Beyond security, we factored in usability, value for money, and the provider’s track record. A fast, easy-to-use VPN is more likely to be used consistently, which matters just as much as the underlying tech. Every service on this list meets a minimum standard, but the top performers go well beyond that.
1. ExpressVPN
Strengths
ExpressVPN has built its reputation on consistent security practices and a clear commitment to user privacy. It runs all servers on RAM-only infrastructure (TrustedServer), which means no data is ever written to disk and everything is wiped with each reboot. The service has undergone multiple independent audits, including assessments of its no-logs policy, browser extensions, and backend architecture.
ExpressVPN uses its own Lightway protocol, designed to be fast, open-source, and secure, while still offering OpenVPN and IKEv2 support. It’s also one of the few providers with a proven response to legal pressure. In a high-profile case, Turkish authorities seized a server and found no usable data.
The apps are polished and consistent across platforms, and all come with DNS leak protection, a kill switch, and split tunneling. The company is based in the British Virgin Islands, outside of major surveillance alliances.
Limitations
ExpressVPN allows five simultaneous device connections, which may be limiting for users with multiple devices or households. It’s also more expensive than most competitors, especially when discounts aren’t applied. While it offers strong privacy, it doesn’t allow anonymous sign-up; an email and a payment method are required.
Bottom Line
ExpressVPN is a well-audited, security-focused VPN with strong infrastructure, proven reliability, and a clear privacy track record. It’s a solid choice for users who want a service that prioritizes transparency and performs consistently across platforms.
2. NordVPN
Strengths
NordVPN combines strong technical fundamentals with wide geographic coverage and reliable performance. It uses a custom-built protocol called NordLynx, based on WireGuard, which offers faster speeds without compromising on encryption. The company has completed multiple independent audits of its no-logs policy and backend systems, with results published publicly.
Most of NordVPN’s infrastructure now runs on RAM-only servers, and the company is transitioning to full diskless operation across its network. It also owns and operates colocated servers in high-risk regions, reducing dependence on third parties. Other key features include a built-in kill switch, leak protection, and split tunneling across apps.
NordVPN is based in Panama, outside of EU and U.S. surveillance alliances, and maintains a clear legal stance against data retention.
Limitations
While NordVPN allows six simultaneous connections, managing them across devices isn’t as seamless as some competitors. The desktop app has more features than the mobile version, and some advanced settings (like meshnet or multi-hop) can feel buried. Anonymous sign-up isn’t supported; an email and payment method are required.
Bottom Line
NordVPN is a well-established option with strong security, an improving infrastructure, and a solid audit history. It’s a good fit for users who want consistent speeds, modern encryption, and a provider that invests in long-term privacy.
3. Surfshark
Strengths
Surfshark stands out for offering strong security features at a lower price point, without cutting key protections. It uses AES-256 encryption and supports both WireGuard and OpenVPN protocols. Surfshark operates on RAM-only servers and has undergone multiple independent audits, including of its infrastructure and browser extensions.
One of its most appealing features is unlimited device support, and a single subscription can cover your entire household or workspace. Additional tools like MultiHop (double VPN routing), CleanWeb (malware and ad blocking), and DNS leak protection are included by default. The apps are well-designed, consistent across platforms, and easy to configure.
Surfshark is based in the Netherlands, a country with data protection laws that are compatible with privacy-first operations, although technically part of the 14-Eyes alliance.
Limitations
Some of Surfshark’s advanced tools (like rotating IP or NoBorders mode) may not be useful for average users, and the impact on performance can vary. While it has a strong feature set, it doesn’t yet match the proven long-term track record of more established providers like ExpressVPN or NordVPN.
Bottom Line
Surfshark is a strong choice for anyone looking for affordable, secure VPN access across unlimited devices. With audited infrastructure, RAM-only servers, and a solid set of privacy features, it offers real value, especially for families or users who want to cover multiple endpoints.
4. Mullvad
Strengths
Mullvad takes a stricter approach to privacy than most VPNs. It doesn’t ask for an email address or any personal information. Users generate an anonymous account number and can pay with cash, cryptocurrency, or privacy-friendly payment methods. This minimal data model makes it nearly impossible to link activity back to a user.
The service uses OpenVPN and WireGuard, both with strong default encryption, and its entire app ecosystem is open source. Mullvad has undergone independent audits of both infrastructure and codebase, and regularly publishes transparency reports. It also uses diskless servers, enforces no-logs by design, and supports advanced features like bridge servers and split tunneling.
Headquartered in Sweden, Mullvad operates under EU privacy laws but avoids data collection through architectural choices rather than policy promises.
Limitations
Mullvad’s apps are functional but minimalist. There are no built-in ad blockers, no streaming-optimized servers, and no unlimited-device options. It also offers just one plan at a flat rate, which keeps things simple but may be less flexible for families or businesses.
Bottom Line
Mullvad is the best fit for users who care more about privacy than convenience. Its anonymous sign-up process, open-source apps, and zero tracking policy make it one of the most trustworthy VPNs available, especially for users with higher threat models or advanced privacy needs.
5. Proton VPN
Strengths
Proton VPN is developed by the team behind Proton Mail and shares the same commitment to open-source, privacy-first infrastructure. It’s one of the few services offering a genuinely free plan with no data limits, no ads, and the same strong encryption used in paid tiers.
Proton VPN has undergone independent audits, publishes regular transparency reports, and is based in Switzerland, a country known for strong privacy protections outside the 14-Eyes alliance. It uses AES-256 encryption with support for OpenVPN, IKEv2, and WireGuard, and its Secure Core feature routes traffic through multiple hardened servers in privacy-friendly countries before exiting to the public internet.
All apps are open-source and audited, and include features like DNS leak protection, a kill switch, and alternative routing for bypassing censorship in restricted regions.
Limitations
The free tier, while generous, offers access to a limited number of servers and does not support Secure Core or streaming. Paid plans are more expensive than some competitors, and Secure Core routing can reduce speed, especially over long distances.
Bottom Line
Proton VPN offers an unusually strong balance between transparency, security, and accessibility. Whether you’re just starting out with a free plan or looking for hardened multi-hop protection, it’s one of the most privacy-conscious VPNs available, especially for users already in the Proton ecosystem.
6. Private Internet Access (PIA)
Strengths
Private Internet Access is one of the most transparent VPN providers on the market, with a strong history of defending user privacy in court. It has been repeatedly asked to produce user data in legal cases, and has consistently demonstrated that it keeps no logs.
PIA’s apps are open-source and offer deep customization, supporting multiple protocols including OpenVPN and WireGuard. Users can fine-tune encryption settings, choose from a large global server network, and enable features like Multi-Hop, port forwarding, and a kill switch. The service also includes built-in ad, tracker, and malware blocking through its MACE feature.
While headquartered in the U.S., PIA counters jurisdiction concerns through its strict no-logs implementation, open audits, and independently reviewed privacy policies.
Limitations
PIA’s connection speeds can vary depending on server load and location, and its interface may feel cluttered for users who prefer simpler apps. Being based in the U.S. may be a concern for those with stricter threat models, even with a solid no-logs track record.
Bottom Line
PIA is a well-established VPN with proven legal resistance to data requests and an open-source approach that prioritizes user control. It’s a solid option for users who want advanced features, transparency, and a strong logging policy with a long public history.
7. CyberGhost
Strengths
CyberGhost combines strong privacy protections with ease of use, making it a solid option for users who want secure browsing without complex setup. It offers a large global server network, including its own independently operated “NoSpy” servers housed in a private data center in Romania. These servers are designed for enhanced privacy and are only accessible to CyberGhost’s internal team.
The service supports WireGuard, OpenVPN, and IKEv2 protocols, all with AES-256 encryption. Apps include key security features like a kill switch, DNS and IP leak protection, and split tunneling. CyberGhost has completed third-party audits and publishes a quarterly transparency report that tracks government requests and DMCA notices.
Based in Romania, outside the 14-Eyes alliance, CyberGhost is not subject to mandatory data retention laws, and its no-logs policy has been independently verified.
Limitations
CyberGhost’s desktop app offers more configuration options than its mobile counterpart, and some users report slower speeds on distant servers. While it does provide advanced features, they are less customizable than those found in providers like PIA or Mullvad.
Bottom Line
CyberGhost is a privacy-focused VPN that balances simplicity with serious security. With its dedicated NoSpy servers, consistent audit history, and broad network coverage, it’s a good fit for users who want strong protections without overcomplicating the experience.
8. IPVanish
Strengths
IPVanish offers a good mix of speed, security, and device flexibility, particularly for users who want to cover multiple connections without managing limits. It allows unlimited simultaneous devices under a single subscription, making it useful for families or shared setups.
The service supports WireGuard and OpenVPN, and includes standard protections like a kill switch, DNS leak prevention, and LAN blocking. IPVanish owns and operates its entire server network, a rare setup that gives it full control over hardware and data handling, rather than relying on third-party providers.
In recent years, IPVanish has taken steps to rebuild trust by undergoing an independent no-logs audit, and it now publishes a transparency report. Its apps are available across all major platforms and offer helpful advanced settings for users who want more than just one-click connection.
Limitations
IPVanish’s reputation is still recovering from a past incident where it complied with a data request, before its ownership change and no-logs audit. While improvements have been made, that legacy may be a concern for some users. It’s also based in the U.S., which raises jurisdiction questions for privacy-conscious users.
Bottom Line
IPVanish has matured into a more transparent and secure VPN, with strong infrastructure and unlimited connections. While its past may give cautious users pause, its current practices and independent audit make it a viable option for those prioritizing control and speed.
9. AirVPN
Strengths
AirVPN is a community-driven VPN service with a strong emphasis on technical transparency and user control. Built by activists and hacktivists, it uses open-source tools and offers features designed for users who want deeper insight into how their VPN works.
The service supports OpenVPN and WireGuard, both with strong default configurations. It includes advanced features like port forwarding, VPN over Tor, and dynamic IP routing. AirVPN does not log user activity, operates its own infrastructure, and allows anonymous signup with payment options like cryptocurrency.
Based in Italy, AirVPN is not part of the 14-Eyes alliance, and its privacy policy clearly outlines its no-logs implementation. The company has a reputation for being outspoken on internet freedom and censorship resistance, and provides technical documentation that’s well beyond what most VPNs offer.
Limitations
AirVPN is not designed for casual users. Its interface is functional but dated, and setup requires more manual configuration than mainstream alternatives. There’s no native app for iOS, and customer support is limited to ticket-based responses and community forums.
Bottom Line
AirVPN is a solid option for users who care about transparency and control over convenience. It won’t appeal to everyone, but for privacy-focused users who want a VPN with clear policies, strong encryption, and open-source tooling, it’s one of the most principled options on the market.
10. Windscribe
Strengths
Windscribe offers a solid blend of privacy, customization, and generous free usage, making it one of the few freemium VPNs worth considering for security. Its free plan includes up to 10 GB per month, with access to multiple server locations and full encryption.
The service supports both OpenVPN and WireGuard protocols, with AES-256 encryption and strong default settings. Windscribe includes features like a kill switch (called Firewall), split tunneling, and its R.O.B.E.R.T. tool, a customizable DNS-based blocker for ads, trackers, and malware.
While not formally audited, Windscribe has open-sourced parts of its code, published transparency reports, and demonstrated a willingness to address past missteps publicly, including a 2021 incident involving unsecured servers, after which the company overhauled its infrastructure and encryption handling.
Limitations
Windscribe’s server speeds can be inconsistent, especially on the free tier. It hasn’t yet completed a full independent audit of its no-logs policy or infrastructure, which may be a deciding factor for users with higher security expectations.
Bottom Line
Windscribe is a practical choice for users who want flexibility, fair free access, and a provider that communicates openly. While not the most hardened service on this list, its security features and ongoing transparency make it a useful VPN, especially for light users or those just getting started.

Frequently Asked Questions
Is WireGuard more secure than OpenVPN?
WireGuard is a newer protocol designed to be faster and more efficient than OpenVPN, with a smaller codebase and modern cryptography. From a security standpoint, both are strong, but WireGuard’s simplicity makes it easier to audit and less prone to misconfiguration. However, OpenVPN is still widely trusted and battle-tested. The best VPNs support both and let users choose based on their needs: performance, compatibility, or specific security features.
Does a no-logs policy guarantee privacy?
Not necessarily. A no-logs policy is only as trustworthy as the provider’s implementation and whether it’s been independently verified. Audited services offer stronger assurances, especially when they’ve passed legal or technical challenges without exposing user data. Look for providers that have completed full infrastructure audits and publish transparency reports regularly. A clear privacy policy is important, but audit-backed proof is what separates claims from credibility.
Conclusion
Choosing a VPN is more than hiding your IP. It elevates privacy, allowing you to control who can see what you do online. The services in this list go beyond basic encryption to offer independently audited privacy policies, secure infrastructure, and real transparency.
For most users, ExpressVPN offers the best balance of trust, speed, and usability. If you’re covering multiple devices on a budget, Surfshark is hard to beat. And if privacy is your top concern, Mullvad offers the most stripped-down, anonymous experience available.
No matter which you choose, make sure your VPN actually does what it promises and doesn’t ask for more trust than it deserves.
