FreeGuard Testing Methodology
آخر تحقق: 2026-04-15
This page describes how FreeGuard tests VPN performance, security, and reliability across all server regions. Our testing methodology is transparent and reproducible.
Tools We Use
iperf3
Measures raw TCP/UDP throughput between the test client and a controlled iperf3 server placed at each target location.
ping / mtr
Measures round-trip latency and hop-by-hop packet loss using ICMP echo requests over a 60-second window.
اختبار تسرب DNS
يرسل هذا الفحص استعلام A عن freeguardvpn.com إلى كل موفر DNS عام عبر HTTPS في القائمة، ويعرض بيانات الاستجابة فقط. ولا يمكنه تحديد محلل DNS التكراري لجهازك أو ما إذا كان أي طلب يستخدم نفق VPN.
WebRTC leak checker (headless Chromium)
Automates a headless Chromium session to capture local and public ICE candidates and compares them against the expected VPN IP.
اختبار تسرب IPv6
لا تثبت نقطة النهاية ثنائية المكدس الواحدة هذه ما إذا كان IPv6 يمر عبر النفق أو محظورًا. يتطلب الفحص الحقيقي مسبار IPv6 فقط مملوكًا على كل شبكة.
Wireshark / tshark
Captures live traffic during each test run to confirm all packets flow through the encrypted tunnel and none bypass it.
Test Environment
Hardware
Dedicated bare-metal test machines with 8-core CPUs, 32 GB RAM, and 1 Gbps NIC — ensuring the client is never the bottleneck.
Network Conditions
Tests are run across multiple ISPs per source location, covering fiber, cable, and 4G/LTE connections to capture real-world variance.
Geographic Distribution
Tests are executed from 10+ source countries across Asia, Europe, and North America to reflect global user conditions.
Test Protocol
Each server location follows this standardized step-by-step procedure:
Connect to target VPN server
Establish the tunnel using the FreeGuard client. Wait 10 seconds for routing tables to stabilize.
Verify tunnel IP
Confirm the public IP matches the expected VPN server egress address before any measurements begin.
Run speed test (iperf3)
Execute a 30-second bidirectional iperf3 test. Record download, upload, and jitter.
Measure latency (ping/mtr)
Send 100 ICMP packets to the target. Record min, avg, max RTT and packet loss percentage.
اختبار تسرب DNS
للتحقق من تسرب DNS، قارن إعدادات DNS في نظام التشغيل والمتصفح وVPN مع التقاط الحزم أو سجلات المحلل على شبكات حقيقية.
Run WebRTC leak test
Launch headless Chromium, collect ICE candidates, and assert no real IP is exposed.
اختبار تسرب IPv6
لا تثبت نقطة النهاية ثنائية المكدس الواحدة هذه ما إذا كان IPv6 يمر عبر النفق أو محظورًا. يتطلب الفحص الحقيقي مسبار IPv6 فقط مملوكًا على كل شبكة.
Disconnect and reset
Tear down the tunnel, flush routing tables, and wait 30 seconds before the next run.
Repeat 3× and average
Perform the full sequence 3 times per session. Compute the mean for speed and latency; treat any single leak as a failure.
Test Schedule
Tests are conducted monthly across all server regions. Results are updated on corresponding tool, gaming, and streaming pages within 48 hours of completion.
Sample Size
Each server location is tested a minimum of 3 times from at least 2 different source locations. Final metrics are the arithmetic mean of all runs, with outliers (±2σ) discarded.
How to Reproduce Our Results
You can verify our results independently using the same open-source tools. Here is the minimal setup:
