OneVPN Review

OneVPN is an extremely basic service that shows some signs of promise for the future. It is a Hong Kong based VPN provider that doesn't keep logs and provides fast enough connections for streaming. This means that it has a solid base to build on - but it is sadly a bit too expensive to recommend in its current state. Sadly, I was unable to confirm the implementation of its encryption. In addition, it suffered from DNS leaks meaning that I can't consider this VPN good for privacy.

On its website, OneVPN makes a big deal about offering malware protection, ad-blocking, and a NAT Firewall. However, as far as I can tell no ads were blocked while using the service. Other than that, the VPN has very few features:

  • Servers in 59 countries
  • Fast speeds for streaming
  • 3 simultaneous connections
  • Port selection
  • 24/7 support (including live chat support and a ticket system)

OneVPN offers 2 US-based “Netflix servers,” but these were both blocked by Netflix in my tests. BBC iPlayer, however, was accessible using OneVPN’s UK servers.

Speed and Performance

Tests were performed on a 50 Mbs/3 Mbps UK fiber connection (using an AC1200 powerline adapter). OpenVPN tests were performed using UDP (faster but less reliable than TCP). My base tests produced results of around 52 Mbps. The UK server fared very well giving me an average speed of 45 Mbps. The US server performed just as impressively, reducing my speeds by just 5 to 10 Mbps (despite the extra distances involved). Upload speeds were also impressive and barely changed with and without the VPN connected.

The custom client does nothing to prevent DNS leaks or WebRTC leaks. However, I did follow the steps listed in the Knowledgebase article “How to avoid DNS leaks”. Disabling IPv6 does, of course, work, but I otherwise continued to see DNS leaks after modifying the OpenVPN configuration file used by the client as instructed. This pretty much rues the VPN out for privacy.

Price and Plans

OneVPN charges $7.95 per month, with reductions for longer-term plans. The price goes down to just $1 a month for a 4-year plan. An option that is almost suspiciously cheap. All of the subscription plans provide access to all the VPN features.

A 7-day money back guarantee is available, but it is worth checking the small print. In order to receive a refund, you must state a reason for the refund claim. Even worse, a refund is not available if you have used more than 3GB of data.

Consumers can pay for the VPN with all major credit cards, Bitcoin (via BitPay), PayPal, Paymentwall, AliPay and gift cards.

Privacy and Security

Being based in Hong Kong is good for privacy as it has no mandatory data retention laws. Though of course, there is always the concern that China is managing to perform some sort of covert surveillance there. According to its privacy policy OneVPN claims to keep zero logs, which is excellent. This means the VPN can be considered good for privacy.

OneVPN subscribers get the use of a number of protocols:  OpenVPN, L2TP, and PPTP VPN protocols. OneVPN also supports the open source Cisco OpenConnect (CSTP) protocol. This is a SSL/TLS-based VPN protocol.

As is always the case we checked the implementation standards of OpenVPN: an AES-256 cipher with an RSA-2048 handshake and SHA 256 hash authentication. This is pretty good. However, I was unable to ascertain whether OneVPN also implements Perfect Forward Secrecy (ephemeral keys). This “detail” is important because if PFS is not used then the same key is used each time you connect to the VPN server. This makes the connection much easier to hack.

Sadly, I have no way to know whether OpenVPN is absolutely secure with OneVPN. Add this to the DNS leaks that were discovered in my tests, and it is close to impossible to recommend this VPN for privacy.

Final thoughts

As this OneVPN review shows, OneVPN is about as bare-bones as a VPN service gets. You get a simple VPN connection, and that’s it.  It claims to offer important features such as DNS leak protection and a kill switch through its guides, but these simply don’t work.

In its current state, it is therefore hard to recommend OneVPN. That said, not all is bad. OneVPN is a Hong-based no logs provider, and its performance is excellent. This actually means that OneVPN has a strong base on which to build and improve its service in the future. It might, therefore, be worth keeping an eye on.

SCAMMERS! They offered you a lifetime subscription for $48, but they stopped your subscription after a few weeks and you can't ask for a refund. I tried to contact their customer service in Hong Kong but no respond. A typical discouragement policy! They also blocked all communications (email, online chat, online support). It seems that they already took many people money and fled away. I think they already open a new VPN provider with different company name.

Finally OneVPN's website ( is back after staying offline for around a week. But still their knowledgebase section refuses to open any link so you can't even see any setup tutorial or server addresses. Moreover the so-called 24/7 live chat is still offline as it was before the website went down. Servers condition is same, most of them do not connect and many of them connect but you cant browse anything over internet after connecting. The worst part is that there is no one whom you can complain because there is nothing which can be called as "customer service" when it comes to OneVPN. Never ever buy.

onevpn's website ( can't open for 2 days. Dont know what is hapenning. They already had no customer support for around a month as the live chat was always offline and they did not reply on emails but now, the website is offline itself. Any idea where they went after selling too many annual, lifetime and other accounts? If you have paid for a onevpn acount, just keep regretting now bcoz you have been fooled..
