The most secure VPN providers: safe options for the best security and encryption, tested by in-house experts

best Secure VPN

The reputation of a VPN service rests on its ability to provide a safe and secure internet connection, no matter your location, network speed, or indeed the task at hand. With many of the best VPNs issuing constant updates to buff up security and fix weaknesses, it can be hard to find the most secure VPN on the market.

In truth, only a few of the most reliable and proven VPNs are really worth your hard-earned money – especially if your main concern is keeping your online activity safe and away from prying eyes or would-be bad actors.

There are a number of important factors to consider when it comes to picking a security-focued VPN. You’ll want to go with a VPN that offers state of the art encryption, with options for post-quantum encryption if possible. IP scrambling and VPN obfuscation both make it harder for snoopers to track your VPN activity, or tell you’re using a VPN whatsoever. And third-party audits are an important measure of how well a VPN manages to uphold its own privacy policies.

Right now, ExpressVPN ranks as our pick for the best secure VPN thanks to best-in-class security features and a seemingly insatiable appetite for third-party auditing. Surfshark isn’t far behind, and overall champ NordVPN delivers similarly strong encryption.

With more than 10 years of VPN experience in total, the TechRadar VPN team have tested and reviewed all of the best VPN services on the market, putting each one through its paces to explore features and benefits and uncover any drawbacks. Keep reading for a rundown of the most secure VPNs based on this expert testing.

5 best secure VPNs: quick overview

1. ExpressVPNThe best secure VPN

1. ExpressVPN – from $3 per month
The best secure VPN
ExpressVPN tops our list thanks to a combination of post-quantum encryption, RAM-only servers that dump info with every reboot, and an excellent no-logs policy with a record of more than two dozen independent audits. Its base in the British Virgin Islands excludes it from intelligence-sharing alliances and reporting obligations. It’s also reliably fast and a great pick for everyday browsing and streaming. All of ExpressVPN’s long-term plans come with a 30-day money-back guarantee, making it easy to try before you commit fully.

2. NordVPNThe best VPN overall

2. NordVPN – from $3.49 per month
The best VPN overall
NordVPN is almost as secure as ExpressVPN, with 256-bit encryption, an internet kill-switch for unsecured networks, and great DNS leak protection. Its Threat Protection Pro system blocks malware, ads, and trackers more effectively than any other VPN we’ve tested, and automatically scans downloads for malware. That effectively turns NordVPN into an anti-virus system, alongside one of the most feature-rich and reliable VPNs on the market. As with ExpressVPN, a 30-day money back guarantee protects your purchase.

3. Private Internet Access (PIA)The best Linux VPN

3. Private Internet Access (PIA) - from $2.19 per month
The best Linux VPN
Budget contender PIA comes with some serious security options that go above and beyond expectations for such a cheap VPN. It offers customizable encryption, multi-hop with built-in obfuscation, and a no-logs policy that’s so robust it’s been proven in court, twice. If you’re looking to get around restrictive network rules or tailor your VPN to your security requirements, PIA is a solid option that comes in much cheaper than many competitors.

4. Proton VPNThe best VPN for privacy

4. Proton VPN – from $2.99 per month
The best VPN for privacy
Proton VPN, based in Switzerland, is a simple and sleek VPN that happens to offer some of the best privacy and security tech of any VPN while keeping costs low. Its servers use full-disk encryption, meaning nobody can access your data as it travels through Proton’s network, and its home country is famously resistant to intelligence sharing or data requests.

5. Surfshark – from $2.19 per monthThe best cheap VPN

5. Surfshark – from $2.19 per month
The best cheap VPN
Our pick for the best cheap VPN is also one of the most secure. Like NordVPN, Surfshark comes with an anti-virus built into the client, and goes a step further by monitoring the dark web for threats and data leaks. CleanWeb blocks ads and prevents you from connecting to suspicious sites, making malware and hacks less likely. Multi-hop functionality gives further peace of mind by totally blurring your usage data and footprint, and its no-logs policy and encryption are both excellent – it even offers post-quantum encryption over WireGuard. It’s very affordable, with a 30-day money-back guarantee to protect your options.

1. ExpressVPN

An audited no-logs policy and sleek apps

Server locations: 190+ | Maximum devices supported: 14 (depending on plan) | Refund period: 30 days | 24/7 customer support: Yes

Audited no-logs service
Ultra-reliable kill switch
Intuitive apps for all devices
Excellent 24/7 customer support
Above average prices
Not the fastest VPN

ExpressVPN isn't the most feature-rich VPN in our shortlist, but it claims the top spot in our rankings for one crucial reason – it was built from the ground up to prioritize user security. Even a quick look under the hood makes it abundantly clear that every decision has been made with privacy in mind.

The best VPN overall

2. NordVPN

The best all-in-one security suite

Server locations: 210+ | Maximum devices supported: 10 | Refund period: 30 days | 24/7 customer support: Yes

Double data encryption
Lightning-fast speeds
Audited apps, no logging claims, IOxT certification of Android app
New Meshnet feature to securely link devices
Some user interface shortcomings
Basic browser extensions

It’s neck and neck between NordVPN and ExpressVPN when it comes to security. While ExpressVPN focuses on getting core VPN features right, NordVPN offers a whole suite of security tools that keep your device from being compromised. However, some of these features aren’t available on the cheaper plans, so you’ll need to make sure you pick the right option for your needs.

The best VPN for Linux

3. Private Internet Access (PIA)

My top pick for Linux with a full stack of security tools

Server locations: 151 | Maximum devices supported: Unlimited | Refund period: 30 days | 24/7 customer support: Yes

Open-source apps
Dedicated streaming servers
Tons of customizable features
Port forwarding included
Audited no-logs policy
Below-average WireGuard speeds
Not as beginner-friendly as other providers

PIA is a veteran in the VPN space, with over a decade of expertise in providing privacy solutions. It’s reflected in its app, as PIA provides plenty of customisation options that allow you to choose between speed and security as necessary.

However, the real reason that PIA is on our list is because its no-logs policy has been battle-tested. It has been summoned to court twice to provide internet browsing data from its customers. Both times, PIA has demonstrated that it's unable to comply, because it simply doesn’t hold onto customer data.

4. Proton VPN

A privacy-focused provider that you can try for free

Server locations: 190+ | Maximum devices supported: 10 | Refund period: 30 days – free version available | 24/7 customer support: No

Open-source, audited, and top-quality apps 
Free plan with unlimited bandwidth
No significant logging of any kind  
Improved network coverage (also for free plan)

Somewhat pricey
Customer support needs improvement

Swiss firm Proton develops an entire suite of privacy-preserving tools, including Proton VPN. Developed by the same team behind Proton Mail, Proton VPN has a zero-compromise approach to user privacy. Being based in Switzerland, means that Proton benefits from some rock-solid privacy protection laws that prevent law enforcement from requesting IP data.

ExpressVPN and NordVPN both have slightly more extensive security features on offer, but that’s not to say that Proton VPN lags behind. It's constantly improving both the VPN client apps and security features on offer.

The best cheap VPN

5. Surfshark

Great value for a secure VPN that scores well in every area

Server locations: 142 | Maximum device supported : Unlimited | Refund period: 30 days | 24/7 customer support: Yes

Improved WireGuard speeds
Unlimited simultaneous connections
A dream to use
Excellent unblocking capabilities
Pause VPN feature
No notification if your VPN drops

Surfshark is the best cheap VPN on the market, but that doesn’t mean it underperforms when it comes to security. Surfshark’s security features are underpinned by a software-defined network called Nexus, which allows Surfshark to offer features like full multi-hop coverage that other VPN providers can’t match.

Notable for its security creds, Surfshark is the first major VPN to offer post-quantum encryption for WireGuard connections, adding a major security boost to a protocol that generally favours connection speed over hardcore data protection.

Unfortunately, the most impressive security features are locked behind an additional subscription to Surfshark One. On the flip side, Surfshark is one of the only VPNs out there that offers unlimited simultaneous connections, so if you’ve got a significant number of devices you need to protect, then Surfshark’s a great choice.

How does VPN encryption work?

Encryption can only go so far. If the authorities demand logs or other details on users from a VPN firm, encryption won’t stop the provider from handing said details over – which is why you should always be on the lookout for a firm that has a super-solid ‘no logs’ policy. That’s because while encryption might keep your data private and unreadable to your ISP, it’s still visible to the VPN itself.

That’s a common misconception about VPN security and encryption in regard to online privacy. Further misunderstandings can stem from the mishmash of jargon that surrounds talk of encryption, which is all likely to be meaningless to the casual VPN user. Terms like 128-bit, 256-bit, and AES are likely to confuse, so a bit of explanation is in order.

Encryption relies on advanced mathematical formulae to work its magic. Some types of encryption are stronger than others, and that’s where the terms 128-bit and 256-bit enter the picture – the latter is stronger than the former.

AES stands for Advanced Encryption Standard and is the computer cipher or the actual algorithm used to perform the encryption.

Want to learn more?

We cover all of the key concepts, without the techy jargon, in our guide to encryption.

Blowfish and AES are by far the most common ciphers found in daily VPN usage, and you’ll most commonly see VPN providers offering AES 256-bit encryption. The latter is something of a worldwide standard for solid security, with 256-bit encryption producing a staggering 1.1579 x 10 to the power of 77 possible keys.

Given that, even if you were using the combined power of all the world’s most powerful supercomputers, it’s not possible to pull off a brute-force attack to crack a symmetric 256-bit key (not before the death of the universe rolled around, anyway.)

Also, worth mentioning is Perfect Forward Secrecy (PFS), a system of private encryption keys generated for each new session – this basically ensures that even if the current particular key in use is somehow compromised, the encryption of past sessions can’t be cracked (because they all use a different key).

The best secure VPN FAQs

What is the most secure VPN?

Defining the most secure VPN on an objective basis is impossible, as we aren’t privy to the backend code and corporate operations of each VPN service. Of the ones we’ve tested, though, we’re most confident in ExpressVPN. Its Lightway protocol is proprietary, meaning only ExpressVPN has control over its implementation, and supports post-quantum encryption – meaning it’s unbreakable by conventional means.

Add in RAM-only servers that totally flush all data with each reboot, and a no-logs policy backed by continuous, enthusiastic auditing, and ExpressVPN stands above the rest as a secure VPN provider. That said, all of the VPNs on this list are very secure, and many offer unique or powerful features.

Are VPNs good for security?

We recommend using a VPN whenever possible due to their benefits for security and online privacy, but using one won’t fix all of your security needs on its own. You’ll be less vulnerable to hacking and malware with many of the VPNs listed above, but a solid antivirus and knowledge of how to stay safe while browsing are still equally essential.

VPNs encrypt your internet traffic, making it nearly impossible for your ISP to identify what you’re doing with your connection. They also hide your IP address when you’re using the internet, so that the services you interact with see your VPN IP address instead. Where possible, you should choose a VPN with audited no-logs policies, leak protection, and up-to-date encryption protocols.

Which VPN protocol should I use?

It depends on your use case, but generally, WireGuard, OpenVPN, and IKEv2 are all appropriate choices for secure VPN protocols. WireGuard is currently the best balance of speed and security, but it’s not as widely supported as OpenVPN. OpenVPN has been thoroughly tested and is in use at the enterprise level all over the world, but the large codebase and heavyweight implementation make it significantly slower than WireGuard or IKEv2. IKEv2’s best for use on mobile devices. Avoid outdated protocols like PPTP or L2TP whenever possible.
