How We Test & Review VPN Services

We thoroughly test every VPN before recommending it. In this guide, you’ll learn about our testing lab, how we evaluate VPNs, how our rating system works, and why you can trust our process.

Why Trust Our VPN Reviews?

All 61 VPNs on our site go through our rigorous and fair testing system. This ensures accuracy and comparability of our results. We designed this system to recommend only the best VPNs.

We choose VPNs based on app store data, expert recommendations, and popularity. Our testing process is fully transparent—each review includes a breakdown of ratings, and our findings can be replicated.

  1. 100% Independent​

At Top10VPN.com we pride ourselves on genuine, 100% editorial independence. What does that mean?

No conflict of interest

Unlike many other VPN review websites, we are independent and separate from all VPN providers. There’s no financial influence affecting our reviews.

Dedicated to VPNs Only

We focus entirely on VPNs, online privacy, and security. This means we dedicate all our time and resources to providing the best VPN reviews and advice.

Self-Funded Subscriptions

To ensure full impartiality, we buy every VPN subscription ourselves. Since 2016, BestVPN has spent over $25,000 on VPN subscriptions alone.

Supported by Our Readers

Our work is completely funded by our readers. If you want to know how we make money, we provide full transparency.

2. Expert Reviewers

Our reviews and guides are written by VPN experts with years of experience in cybersecurity and tech reviews.

  • Simon Migliano – Cybersecurity researcher, featured in top news publications.

  • JP Jones – 25+ years in software engineering and network security.

  • Callum Tennent – Product testing expert, specializing in unbiased evaluations.

We also have an in-house team of engineers, data analysts, and web censorship specialists who support our testing process.

3. Original Research

Unlike many other VPN review sites, we conduct our own tests to assess performance. Our reviews are based on real-world testing using primary and third-party tools.

 

For example, we developed a custom VPN kill switch testing tool to analyze security flaws. Some VPNs, like PrivateVPN, have used our findings to improve their security.

You can find more details about our VPN testing methodology on this page.

4. Up-to-Date Information

VPN performance changes frequently. A VPN that unblocks Netflix today might not work next week. VPN providers also add new features to address security threats.

To keep our reviews accurate, we continually retest VPN services and update our content weekly. An initial review may take 40+ hours, but we spend many more hours each month keeping it updated.

Our experts frequently retest speeds, verify streaming access, and update pricing and security data to keep our information relevant.

5. Consistent Testing Environment

To ensure fairness and comparability, we test all VPNs in a controlled environment. Each VPN is tested hands-on from New York using standardized hardware and the latest OS versions.

Additionally, every VPN is tested in an independent virtual machine to prevent interference from other software. This ensures accurate and consistent results.

Here’s a list of some of the test devices we use:

Using the same devices helps us isolate VPN performance from device-specific issues.

VPN Test & Rating Methodology

We use two rating categories: Overall Ratings and Use Case Ratings.

Overall Ratings

These ratings evaluate VPNs based on a fixed set of criteria that apply to all users. Use case ratings assess VPNs for specific needs, such as streaming or security.

1. Privacy (20% of Overall Rating)

A VPN’s logging policy is critical. Too much logging can expose your data if a hacker or court accesses the VPN’s servers.

How We Test

  • We carefully read every VPN’s logging policy.

  • We analyze what data is stored and for how long.

  • We examine the VPN’s jurisdiction and any privacy risks.

  • We assess privacy-enhancing features, such as diskless servers.

To ensure accuracy, multiple testers review each policy independently.

How We Rate

We use a custom-built calculator to provide accurate and objective ratings.

We use a custom-built rating system:

  • Data Logged (60%) – The less data logged, the better.

  • History (20%) – Past privacy incidents impact the score.

  • Jurisdiction (10%) – Some countries have strict data laws.

  • Trustworthiness (5%) – Based on audits and past behavior.

  • Privacy Features (5%) – Includes diskless servers and encryption.

Each VPN starts with a 10/10 rating, and points are deducted based on privacy risks.

  • 0.1 – 3.0: Logs large amounts of personal data; high risk.

  • 3.1 – 5.9: Logs more than ideal; jurisdiction may be a concern.

  • 6.0 – 7.9: Some privacy concerns, but acceptable.

  • 8.0 – 9.4: Strong privacy measures, minimal logging.

  • 9.5+: Best-in-class privacy; independent audits confirm security.

2. Streaming (15% of Overall Rating)

Streaming performance measures how well a VPN can unblock geo-restricted content on platforms like Netflix, BBC iPlayer, and Hulu.

How We Test

We connect to a VPN server in the target region and try to stream content. We check if the video loads, the audio and video sync correctly, and there are no interruptions.

We have accounts with 120 global streaming services. Popular services like US Netflix and BBC iPlayer are tested weekly. Less popular platforms are tested monthly. We track each VPN’s success rate over three and 12 months to measure reliability.

Regularly Tested Streaming Services:

How We Rate

Here is the scoring system we use to calculate a VPN’s streaming rating:

We also factor in video quality, load time, and buffering to determine a VPN’s final score.

3. Speed (15% of Overall Rating)

A VPN’s speed affects how quickly you can browse, download, and stream content.

How We Test

We measure speeds using our in-house speed test tool on a 100Mbps connection. We test servers in 8 countries across 5 continents:

  • US (West & East Coast)

  • Australia

  • Brazil

  • Canada

  • Germany

  • Japan

  • South Africa

  • UK

Each location is tested three times a week for a month to ensure accuracy.

How We Rate

We input the raw speed data into our custom calculator, which calculates an overall speed rating.

This category is divided into the following subcategories:

Scoring Breakdown:

  • 0.1 – 3.9: Very slow, 80%+ speed reduction.

  • 4.0 – 4.9: Slow, 60-80% speed reduction.

  • 5.0 – 6.9: Average, 30-60% speed reduction.

  • 7.0 – 8.9: Good, 10-30% speed reduction.

  • 9.0 – 9.8: Excellent, minimal speed loss.

  • 9.9 – 10.0: Outstanding, almost no speed loss.

4. Security (15% of Overall Rating)

A VPN should provide a secure, encrypted connection to protect user privacy.

How We Test

We use tools like Wireshark to verify encryption and analyze traffic.

  • AES-256 or ChaCha20 encryption is preferred.

  • OpenVPN, WireGuard, or IKEv2 are the safest protocols.

We also check:

  • IP & DNS Leak Protection

  • VPN Kill Switch Effectiveness

  • Ad & Tracker Blocking

How We Rate

  • 0.1 – 3.0: Major security flaws, logs data, leaks IP/DNS.

  • 3.1 – 5.9: Outdated encryption or leaks detected.

  • 6.0 – 7.9: Functional but lacks advanced features.

  • 8.0 – 9.4: Strong security with robust encryption.

  • 9.5+: Best-in-class security, multiple audits, zero leaks.


 

5. Server Locations (10% of Overall Rating)

The number of server locations impacts content accessibility and connection speeds.

How We Test

We examine each VPN’s server list and document:

  • Total server count

  • Number of available countries

  • City-level locations

How We Rate

  • 0.1 – 0.9: Single fixed server location.

  • 1.0 – 5.9: 2-6 country locations.

  • 7.0 – 8.9: User-friendly, minor improvements needed.

  • 9.0 – 10.0: Extremely intuitive, seamless across platforms.


 

7. Torrenting (5% of Overall Rating)

We test how well a VPN can protect your P2P file-sharing activity from your ISP and other third parties while maintaining fast download speeds.

How We Test

Use Case Ratings

For specific needs like streaming, gaming, or privacy, we adjust our rating criteria to reflect the most relevant factors. This ensures our recommendations are tailored to different user requirements.

Our methodology adapts depending on the category, but always follows strict, data-driven evaluation processes.

In scenarios where use case ratings are applied, we explain the testing and scoring methodology directly on the page.
