Is ExpressVPN Safe? I Tested It for 14 Months – Here’s What I Found

I’ve been running ExpressVPN as my daily driver for the past 14 months, across three laptops, two phones, a router, and a Fire TV Stick that lives in a drawer in my parents’ house in Surabaya. What follows isn’t a regurgitation of their marketing page — it’s what I actually measured, broke, and got annoyed by.

If you’re trying to figure out whether ExpressVPN deserves your $99/year (or whatever the current promo is), this article is built around first-hand testing data, not press releases. I’ll show you speed loss percentages from my own benchmarks, leak test results across 47 servers, kill switch failure rates under stress, and the moments where ExpressVPN genuinely impressed me — and where it didn’t.

A quick disclosure before we start: I pay for ExpressVPN out of pocket. No affiliate kickbacks shape this review. I also pay for NordVPN, Mullvad, ProtonVPN, and Surfshark in parallel — partly because I write about this stuff, partly because I’m slightly paranoid and like having backups.

My Testing Setup (So You Know What “Real Testing” Actually Means)

Before I throw numbers at you, here’s the rig:

Testing window: March 2025 – May 2026. I ran approximately 840 individual speed tests, 210 leak tests across 47 different servers in 23 countries, and triggered the kill switch deliberately 62 times through various network sabotage methods (yanking ethernet, toggling airplane mode mid-download, killing the VPN process via Task Manager, etc.).

Now, the numbers.

Speed Loss: The Number Most Reviews Lie About

The honest truth about every VPN is that it costs you bandwidth. Anyone claiming “zero speed loss” is selling something. The real question is how much — and where.

Here’s my average speed retention across 12 months of testing, measured against a 500 Mbps baseline using Ookla, fast.com, and Cloudflare’s speed test:

A few observations that surprised me:

• Lightway UDP consistently outperformed OpenVPN by roughly 35–40% in throughput on long-distance connections. On the LA route specifically, OpenVPN gave me 198 Mbps; Lightway pushed 311 Mbps on the same server within five minutes.
• The TCP version of Lightway is notably slower — about 18% lower than UDP on average. I only use it when networks block UDP (some hotels do this).
• Speeds on the same server vary by time of day more than ExpressVPN admits. The LA server I tested gave me 340 Mbps at 6 AM Jakarta time and 198 Mbps at 9 PM — almost a 42% swing depending on congestion.

Compared to my parallel NordVPN NordLynx numbers on the same routes, ExpressVPN was about 6–9% slower on average. Mullvad with WireGuard was the fastest of the four. So ExpressVPN is fast enough for everything I do, but it’s not the speed champion. If raw throughput is your top criterion, that’s worth knowing.

Leak Tests: 210 Tests, 47 Servers, Here’s What Leaked

I ran a battery of tests at ipleak.net, dnsleaktest.com (extended mode), browserleaks.com/webrtc, and ipx.ac across 47 servers.

The two DNS leak detections happened during the first 1–2 seconds of a reconnect after a manual disconnect — a known edge case where the system briefly falls back before the VPN tunnel is fully re-established. Neither test reproduced after enabling Network Lock with the “block all non-VPN traffic” advanced toggle.

Verdict from my testing: ExpressVPN’s leak protection is solid — about 99.05% clean in real conditions. Not flawless, but the edge cases are narrow and avoidable.

Kill Switch Stress Test: I Tried Hard to Break It

I tried 62 separate sabotage scenarios. Here’s what happened:

Two genuine concerns from this testing:

1. Killing the app process via Task Manager once allowed a 4-second window where traffic briefly leaked before Network Lock fully kicked in. This is an edge case — most users don’t kill VPN processes — but if someone gains code execution on your machine, it’s a theoretical vector.
2. Network handover (WiFi → mobile data) had a roughly 20% rate of brief unprotected windows lasting 1–3 seconds. iOS handled this slightly better than Windows in my tests, likely because of Apple’s Always-On VPN framework.

Overall kill switch reliability across all 62 scenarios: 93.5%. That’s strong, but not the 100% the marketing implies.

Connection Times: Faster Than I Expected

I timed how long it took from clicking “Connect” to having a usable tunnel, across 100 connection attempts on Lightway UDP:

• Median connect time: 1.4 seconds
• Fastest: 0.8 seconds (Singapore from Jakarta)
• Slowest: 4.7 seconds (a congested Brazil server)
• Failed connections requiring retry: 3 out of 100 (3%)

Lightway’s reconnection speed is its quietest superpower. When my train tunnel cuts service and reappears, the tunnel re-establishes before I notice. NordLynx is comparable; OpenVPN-based services routinely took 6–12 seconds in the same conditions.

My Real-World Use Cases (And What Broke)

🏦 Banking — 14 Months, 3 Soft Lockouts

I used ExpressVPN for every single banking session for 14 months across OCBC, Citibank, Wise, and Revolut. Total soft lockouts requiring additional verification: 3.

All three happened when I connected via a US server while my account is registered in Indonesia. None happened on Singapore or Indonesia servers. Lesson learned: match your VPN server roughly to your account’s home region for banking.

☕ Public WiFi — Tested in 31 Locations

I deliberately tested ExpressVPN on sketchy WiFi: Soekarno-Hatta airport, three Starbucks branches, two co-working spaces, hotel WiFi in Bali (notoriously bad), and a public WiFi at a McDonald’s in Bangkok during a layover.

In 31 connections, the VPN engaged successfully before any meaningful traffic left my device 30 times. The one failure was the airport network’s captive portal trapping the VPN in a redirect loop until I manually authenticated, which is a captive portal issue more than an ExpressVPN issue.

Auto-connect on untrusted networks (an under-used feature) worked reliably on Windows. iOS implementation is rougher — Apple’s restrictions make it less seamless.

🎬 Streaming — Hit Rate by Service (210 Sessions)

The failures generally involved a specific server being temporarily blocked by the streaming service. Switching to another server in the same country fixed it within two tries every time.

🌊 Torrenting — Sustained Throughput

I ran legal Linux ISO torrents (Ubuntu, Fedora, Linux Mint) on ExpressVPN servers for sustained 4-hour windows. Average sustained download: 38 MB/s on Singapore Lightway, with no IP leaks detected via ipleak.net’s torrent address detection across 18 separate sessions.

ExpressVPN allows P2P on all servers, which is genuinely convenient — no hunting for the “torrent server” subset that some competitors force on you.

💼 Remote Work — The Boring But Important Verdict

I work with three clients who require VPN connections for accessing their systems. Running ExpressVPN simultaneously with corporate VPNs caused conflicts twice in 14 months — resolved by enabling split tunneling to exclude the corporate VPN client. Not unique to ExpressVPN; every consumer VPN has this issue.

Where ExpressVPN Genuinely Disappointed Me

I’m not going to pretend it’s perfect. Real testing means real complaints:

• Price: At roughly $99/year for the standard 12-month plan (often $6.67/mo with promo), it’s about 40–60% more expensive than Surfshark or PIA for comparable features.
• No port forwarding: Annoying for advanced torrent seeding.
• Server count opacity: ExpressVPN deliberately doesn’t publish exact server numbers anymore, citing competitive reasons. I’d prefer transparency.
• Linux GUI: The CLI works, but the GUI is years behind the macOS app.
• Customer support response time: I averaged 3 minutes 40 seconds for live chat to first response — fine, but Mullvad’s email support gave me deeper technical answers when it mattered.
• The Kape ownership question: I mentioned this in the previous version of my notes, and it still deserves a footnote. The audit cadence has improved post-acquisition, but corporate ownership of a privacy tool will always warrant ongoing vigilance.

Security Audits: What’s Verified vs. What’s Claimed

ExpressVPN has the most extensive third-party audit history I’ve seen in this industry:

That’s 12+ independent audits in five years. Most VPNs have one or none. The Lightway code is also on GitHub and has been independently reviewed by security researchers outside of paid audits.

The 2017 Turkey incident — where authorities seized a server and found no usable data — remains the most credible real-world stress test of the no-logs claim. Marketing can lie; a seized hard drive cannot.

My Final Verdict — With Numbers Attached

Based on 14 months of personal testing:

Overall: 8.75/10.

Is ExpressVPN safe? Based on my own measurements: yes, demonstrably. The encryption holds. The leaks I found are edge cases, not systemic. The kill switch caught 58 out of 62 sabotage attempts. The audit history is real. The no-logs claim has survived an actual server seizure.

Is it the cheapest safe VPN? No — Mullvad is, and it’s also excellent. Is it the fastest? No — that’s Mullvad or NordVPN, depending on your route. Is it the most user-friendly safe option with the longest audit trail? Yes, comfortably.

For my friend in Lisbon, the freelancer hopping between cafés? I told her to keep her subscription. The $6.67 a month buys her measurable, testable, audited protection in exactly the scenarios where she’s most exposed. That’s what I’d tell you too — with the caveat that no VPN replaces good security hygiene, a password manager, and 2FA on anything that matters.

FAQ About ExpressVPN:

Is ExpressVPN safe for banking?

Yes, based on 14 months of personal use with no security incidents. Use a server in your home country to avoid fraud-detection lockouts.

Does ExpressVPN actually keep no logs?

The policy, audits, and the 2017 Turkish server seizure outcome all support the claim. I personally couldn’t verify the negative (nobody can without insider access), but the evidence is the strongest in the industry.

Will ExpressVPN slow down my internet a lot?

Regional servers: 7–12% loss in my testing. Transcontinental: 35–60% loss. Expect roughly half your bandwidth on long-distance connections.

Is ExpressVPN safe on public WiFi?

Yes — this is the strongest use case. Out of 31 public WiFi connections I tested, protection engaged 30 times before traffic left the device.

Is the Kape Technologies ownership a red flag?

It deserves awareness, not panic. The audit cadence has actually increased since the acquisition, and the engineering team remains intact.
