Speedify doesn’t work like most VPNs. Instead of sending your traffic through one internet connection, it can combine several at once, such as your home line and a phone, and keep you online when one of them drops. That’s aimed at people with unreliable connections: RV travelers, remote workers on shaky lines, and live streamers on the road.
Most people use a VPN on a single connection, though, so the bigger question is whether Speedify holds up there too. I tested both on Speedify’s paid plan. With a phone plugged in next to my Ethernet cable, my speed more than doubled. On a single connection, however, the results looked very different. The short verdict comes first.
Speedify
Speedify is a bonding tool first and a VPN second. If you combine two connections, it adds speed and moves your traffic to the backup line when the main one fails. Its kill switch is also strict. On a single connection, though, it slows down sharply on distant servers and unblocks few streaming services. It also keeps more logs than VPNs with audited no-log policies.
Pros
- Channel bonding that adds speed
- Failover to cellular without dropped pings
- Strict kill switch that passed every test
- No DNS, WebRTC, or IPv6 leaks
- Linux and OpenWrt router support
Cons
- Phone not fully used on default settings
- Stream stalls when Ethernet comes back
- Couldn’t unblock BBC iPlayer or Prime Video
- Logs IP addresses
- P2P on one Amsterdam server only
How I Tested Speedify
I tested Speedify in November on the paid Individual plan, which I activated through the 7-day free trial in its Windows app. The trial unlocks the full paid service, and I didn’t use a free account for any test result.
- Speed: a Windows 11 PC in Europe on a wired 190.36 Mbps connection (19.37 Mbps upload, 10 ms ping), tested on Speedtest through London, New York, and Tokyo servers with default settings.
- Channel bonding: the same Ethernet connection plus an Android phone on USB tethering, which recorded 328.84 Mbps on mobile data without a VPN. Every bonding test used Speedify’s London servers, and the Ethernet-only and combined tests used the same Speedtest server.
- Streaming: seven services, with Bypass and ad blockers disabled, after clearing cookies and cache.
- Security: BrowserLeaks for IP, WebRTC, IPv6, and DNS leaks, plus cable pull, process kill, and PC restart tests on the kill switch.
- Torrenting: a Linux Mint ISO in qBittorrent through Speedify’s Torrent Friendly Server in Amsterdam.
Channel Bonding With Ethernet and a Phone
Channel bonding splits your traffic across several internet connections at once, through one encrypted tunnel to a Speedify server. When I plugged in the phone, Speedify detected it automatically and listed it as a second connection set to Automatic, which it showed as Secondary.

I tested each connection alone, then together, through Speedify’s London servers.
| Setup | Download | Upload | Ping |
| Phone alone, no VPN | 328.84 Mbps | 117.93 Mbps | 15 ms |
| Ethernet only | 166.06 Mbps | 18.67 Mbps | 40 ms |
| Phone only | 327.00 Mbps | 126.02 Mbps | 60 ms |
| Both, default settings | 214.90 Mbps | 109.31 Mbps | 44 ms |
| Both, phone set to Primary | 424.88 Mbps | 131.46 Mbps | 42 ms |
| Both, Redundant mode | 291.89 Mbps | 112.05 Mbps | 40 ms |
On Default Settings
With both connections on Automatic and Bonding Mode on Speed, download speed went from 166.06 Mbps to 214.90 Mbps, a 29% gain. Upload rose from 18.67 Mbps to 109.31 Mbps, almost six times faster.

Speedify’s Secondary Threshold, set to 30 Mbps in my Windows app, brings in Secondary connections when Primary speed falls below it. My Ethernet upload is about 19 Mbps, which likely explains why most of the upload went over the phone.
With the Phone Set to Primary
To use the phone fully, click its connection in Speedify’s list and change Priority from Automatic to Primary. With the phone on Primary, Speedtest recorded 424.88 Mbps down and 131.46 Mbps up, with a 42 ms ping.
Speedify’s own graph peaked at 518.6 Mbps during the test, about the sum of my Ethernet baseline (190.36 Mbps) and the phone’s speed without a VPN (328.84 Mbps), recorded separately. The Speedtest result is 82% of that sum, under the “up to 95%” Speedify advertises.
In Redundant Mode
Redundant mode sends every packet over both connections at once, so the data still arrives if one of them drops. Speedify pitches it for live streams and video calls.
Because every packet travels twice, download speed fell to 291.89 Mbps, below the phone’s 327.00 Mbps on its own, and upload was 112.05 Mbps.
Mobile Data Used
Bonding uses mobile data fast. A single phone-only Speedtest used 0.85 GB, and the test on default settings used 0.28 GB. The Primary and Redundant tests used 1.70 GB between them.
On a limited mobile plan, set a data limit for the phone in its connection settings. Setting the phone to Never keeps it out completely: during my Ethernet-only test, its data counter didn’t move.
Failover When the Ethernet Cable Comes Out
For this test, I kept the default settings, played a YouTube live stream, and left a continuous ping going in Command Prompt. Then I pulled the Ethernet cable. The stream kept playing. One ping reply took 200 ms as Speedify moved the traffic to the phone, and ping then settled at 60 to 91 ms, up from about 42 ms over Ethernet.
Plugging the cable back in, however, went worse. The ping showed a single 280 ms spike and was back to about 42 ms in five seconds, and none of the 133 pings in the test were lost. The live stream still paused for about 25 seconds on my first try.
On the second, it stopped and started several times before it settled. Failover to the phone is smooth, while the switch back to Ethernet interrupts live video.
Speed on a Single Connection
Without a second connection, Speedify works like any other VPN, and distance hurts it. On my 190.36 Mbps line, download speed dropped 7.4% on the London server, 30.8% on the New York server, and 44.9% on the Tokyo server.

That’s a 27.7% speed loss on average. By comparison, NordVPN lost 7.8% of its speed on average across the same three server locations. Upload also fell as servers got farther away, down to 11.76 Mbps on the Tokyo server, a 39.3% upload loss.
| Server | Download | Upload | Ping | Speed loss |
| No VPN | 190.36 Mbps | 19.37 Mbps | 10 ms | None |
| London | 176.31 Mbps | 18.32 Mbps | 42 ms | 7.4% |
| New York | 131.69 Mbps | 14.87 Mbps | 121 ms | 30.8% |
| Tokyo | 104.83 Mbps | 11.76 Mbps | 270 ms | 44.9% |
Speedify was on its defaults: Auto transport mode, Speed bonding mode, and encryption enabled. Speeds also vary between sessions, which is why my separate Ethernet-only bonding test recorded 166.06 Mbps on the same London server.
Streaming With Bypass Disabled
Speedify states that it doesn’t unblock geo-restricted content, and its Bypass feature reflects that. On Windows, Bypass sends 11 services outside the VPN by default, including Netflix, Hulu, HBO, and Peacock.

As a result, those services see your own IP address and show your local catalog. The Android app lists 25. That’s why every streaming test ran with Bypass disabled.
| Streaming service | Server | Result |
| Netflix US | US | Unblocked |
| Prime Video | US | Blocked |
| Netflix UK | UK | Unblocked |
| Channel 4 | UK | Unblocked |
| BBC iPlayer | UK | Blocked |
| ITVX | UK | Blocked |
| Netflix Japan | Japan | Blocked |
Speedify unblocked Netflix US, Netflix UK, and Channel 4. It couldn’t unblock Prime Video, BBC iPlayer, ITVX, or Netflix Japan, which showed geo-restriction messages or wouldn’t play.

For libraries past Netflix US and UK, and for BBC iPlayer, I’d go with one of the VPNs that work with Netflix in more regions.
Torrenting Only Through Amsterdam
Speedify allows P2P traffic only through its Torrent Friendly Server in Amsterdam, and its terms of service prohibit BitTorrent on servers not marked for P2P. When I started a torrent on a US server, Speedify offered to move me to its P2P server, which switched the connection to the Netherlands.

On that server, a 1.89 GiB Linux Mint ISO (about 2 GB) downloaded in qBittorrent at 12.9 MiB/s on average. That’s about 108 Mbps, with a 13.6 MiB/s peak. The speed is good, but the single location is limiting. You can’t download torrents in Amsterdam and keep a US IP address for live sports during the same session.
Encryption, Leaks, and the Kill Switch
Encryption and Protocols
Speedify uses its own bonding protocol over DTLS 1.2, with AES-256-GCM on devices whose chips support AES acceleration and ChaCha20-Poly1305 on the rest. You can disable encryption for a small speed gain, but that leaves your traffic visible to your ISP and others on your network.

Speedify also doesn’t offer WireGuard or OpenVPN, so the protocol choice most VPNs give you isn’t there. Transport modes are Auto, UDP, TCP, Multi TCP, and HTTPS. HTTPS mode uses port 443 for networks that block VPN traffic, and Speedify calls it the slowest mode.
Speedify has no dedicated obfuscation feature, and its own support pages warn that it may not work in China or Iran. If your main goal is to unblock websites on a restricted network, choose a VPN with obfuscation.
Leak Tests
On a London server, BrowserLeaks showed a UK IP address with no WebRTC leak and no IPv6 IP address. On the default Auto DNS setting, its DNS test found 22 servers, all of them Cloudflare servers in London.

My ISP’s DNS servers didn’t appear. That’s because DNS and IP leak protection are enabled by default in the Windows app.
Kill Switch
Speedify’s Internet Kill Switch is off by default, with a single On or Off setting. Once enabled, it’s strict: it blocks all traffic while Speedify is disconnected, including when you disconnect it yourself. My connection dropped the moment I enabled it, before I’d connected to a server.
It passed my cable pull, process kill, and PC restart tests. The drawback is availability. Speedify offers the kill switch only in its Windows, iOS, and Android apps, so Mac and Linux users go without one.
Logging and the Privacy Policy
Speedify keeps connection logs. Its privacy policy, last updated in October 2022, says it collects your IP address and device ID when you connect. It also records when each connection starts, how long it lasts, and how much data it uses. It deletes that data after six months.
The app’s privacy notice also lists the network location of your first connection, and App Analytics remains off unless you enable it. On the other hand, the policy says Speedify doesn’t record the websites you visit or the data you exchange, and its features page adds that DNS requests aren’t logged.
It also says Speedify doesn’t share its data with governments unless the law requires it. However, its backend servers are in the United States, no independent audit has verified any of these claims, and Speedify publishes no transparency report.
A US base doesn’t rule out a strong no-logs policy. Private Internet Access, also a US company, couldn’t hand over user logs when the FBI requested them in two court cases.
Who Makes Speedify
Connectify, the Philadelphia company behind Connectify Hotspot, launched Speedify in 2014. In 2011, In-Q-Tel, the venture firm that invests on behalf of the CIA and other US intelligence agencies, made an undisclosed investment in Connectify.
The only independent review Speedify points to is a MASA security assessment of its Android app by the DEKRA lab. It covers the Android app alone, so Speedify’s servers and logging policy haven’t been audited.
In 2025, the security firm SecureLayer7 disclosed a flaw in the macOS app’s helper tool that allowed root access. Speedify says it fixed the flaw in version 15.2 and that Mac App Store installs weren’t affected.
Servers and Locations
Speedify lists servers in 37 countries and 57 cities, and the server list in its app also showed 37 countries. However, it doesn’t publish a server count, and there are no servers in India, Hong Kong, or Taiwan.
The London server’s IP address belonged to Linode, Akamai’s cloud hosting service, so Speedify rents at least part of its network. Free accounts see the same server list as paid ones, but Speedify says paid plans add Premium Servers.
Apps and Ease of Use
I found Speedify’s Windows app confusing. The home screen shows connection statistics, and the server list is behind the three-line menu under Server. Worse, there’s no server search, so you scroll the list by hand, which is baffling. The window resizes freely, which helps, but the app still doesn’t look good to me.

As for devices, one account covers five at once. Speedify supports these platforms:
- Windows 10 and later, and macOS 11.5 and later
- iOS 17 and later, and Android 9 and later
- Linux: Ubuntu, Debian, and Raspberry Pi OS
- OpenWrt routers
- Fire TV through sideloading with the Downloader app, on Fire OS 7 or 8 only

There’s no Apple TV app and no browser extension. On Android, Pair & Share paired my devices on the same account automatically. Pair & Share lets Speedify devices on one local network share their cellular connections, and shared data counts as tethering on your mobile plan.
If a phone is your main device, the best VPNs for Android have simpler apps.
Price per Month, Free Plan, and Refunds
Speedify is expensive for a VPN, even on its longest plan, and most cheap VPNs charge less for a two-year term. Here are its plans:
- Individual: about $5 a month on the three-year plan, $7.50 on the yearly plan, or $15 month to month, for five devices
- Families: about $7.50 a month on the three-year plan or $11 on the yearly plan, for five accounts with five devices each
- Teams: about $7.50 per user a month on the yearly plan, with central management and no cap on users
- Routers: data tiers from 100 GB to 3 TB, from about $11 to $38 a month on yearly plans
- Dedicated server: about $75 a month on the yearly plan, with a static IP address and port forwarding
- Free: 5 GB of data a month with a free account
Free Trial, Cancellation, and Support
The Windows app offers a 7-day free trial of the yearly Individual plan. Checkout shows nothing due, but it still requires a card, PayPal, or Venmo. The trial then turns into the yearly Individual subscription unless you cancel. Speedify also accepts Apple Pay and Google Pay, but not cryptocurrency.
To cancel, sign in to your account on Speedify’s site, select View/Edit Billing, then Cancel Subscription. Speedify first shows a 15% retention offer on the yearly plan, and on my Individual account, the offer named the Families plan by mistake. After you cancel, the plan stops renewing, and you keep access until the paid term ends.
Speedify offers a 30-day money-back guarantee, requested by email. It doesn’t refund renewal payments, and App Store or Google Play purchases go through Apple or Google. Support is by email only, with replies within one business day.
Verdict
Speedify is worth paying for if you have two connections to combine. Few VPNs can merge a home line with a phone or Starlink, and in my tests, that made Speedify both faster and harder to knock offline. If you depend on a connection that keeps cutting out, that alone justifies the price.
As a VPN for a single connection, it’s hard to recommend. Distant servers slow it down sharply, and most of the streaming services I tested remained blocked. It also keeps IP addresses for months, with no audit to back its privacy claims. If privacy comes first, choose one of the VPNs with audited no-log policies.
For streaming on one connection, NordVPN and Proton VPN unblock more services, and ExpressVPN has more beginner-friendly apps.
Frequently Asked Questions
Is Speedify safe?
Yes, for everyday use. Speedify encrypts traffic and blocks DNS and IP leaks, but it logs IP addresses and connection times, and no independent audit has verified its privacy policy.
Is Speedify legit?
Yes. Speedify is made by Connectify, a US software company that has sold it for years. It’s a real paid service, but its logging falls short of privacy-focused VPNs.
Is Speedify worth it?
Yes, if two connections are available to combine, such as home internet and a phone. On a single connection, cheaper VPNs offer better speeds on distant servers and stronger streaming support.
Does Speedify work with Netflix?
Partly. Speedify unblocks some Netflix libraries, such as the US catalog, but its Bypass setting sends Netflix outside the VPN by default, so it has to be switched off first.
Is Speedify free?
Yes, Speedify has a free account with a monthly data limit and the same servers as paid plans. Unlimited data and more devices require a paid Individual, Families, or Teams plan.
Does Speedify have a kill switch?
Yes, on Windows, iOS, and Android. It’s off until enabled, then blocks all internet traffic whenever Speedify disconnects. The macOS and Linux apps don’t include one.
