Viscosity is an OpenVPN client that provides a rich Cocoa user interface for creating, editing, and controlling, and managing VPN connections. Just as displayed on their homepage, Viscosity is a first-class OpenVPN client that lets you secure your network with ease and style on both Mac and Windows OS. Does it offer a package as secure and anonymous as a premium provider like NordVPN, or allow you to unblock Netflix? No, it doesn’t.

Developed by Sparklabs, a software development company founded in early 2008 with its headquarters in Australia, Viscosity offers its clients a complete OpenVPN solution for OS X 10.5 Leopard on Mac PC without any need for additional downloads or third-party software. Viscosity takes advantage of the advanced DNS system present in Mac OS X by fully integrating with it to allow the usage of custom DNS servers and search domains while connected. The program makes use of Mac’s keychain and Windows’s credential system to make sure your details are kept safe and secure.

Viscosity VPN comes with some exciting features that help to optimize the program for your Windows or Mac. These features re-configure your browser’s settings automatically, making sure they are optimized to achieve the greatest level of anonymity on the internet. With Viscosity VPN, you can send emails anonymously from any e-mail service provider as the application helps to conceal your actual geographic location and identity from the recipient.

Viscosity does not offer any restriction on the amount of data you can transfer per session and provides you with unlimited access to switch between different servers. You can rely on Viscosity IP services to bypass any restriction and censorship to make sure you communicate safely with the outside world. Its ability to bypass restrictions stops at communication, it’s unable to unblock Netflix, Hulu, and other popular streaming services.

The installation and configuration of Viscosity through a GUI is simple, seamless, and straightforward as it requires little or no knowledge of the command-line or OpenVPN’s configuration-file syntax. As a super user, Viscosity allows you to manually control and edit the configuration options as you deem fit.

Through Viscosity and OpenVPN, you can easily and securely connect to your home or company network from a remote location as the program offers full protection for your network traffic when using public or wireless networks. It enables you to scale through restrictive firewalls and proxy servers to give your PC access to online content and websites with country restrictions.

The program also allows you to connect to any VPN server running OpenVPN, including the most popular free and commercial VPN providers. The program offers full support for Windows and Mac OS X, but fails to mention the likes of Android, Linux, and Fire devices, which raises questions about its compatibility.

Viscosity offers prospective users 30-day trial period on both Windows and Mac OS, during which they can ascertain whether they are ready to make a long-term commitment or not. The program is relatively affordable.

Does it compare with a tried and trusted vendor like NordVPN? We don’t think so. We recommend NordVPN because it offers global coverage, ease of use, and compatibility with most devices. Not to mention, super-fast speeds and impressive unblocking capabilities for Netflix and a wide-range of other streaming services and websites.

It just works. All the time! - 10

My requirement is to have a VPN connection to my development lab, pretty much constantly. I had spent hours trying to get another (free) Open VPN client working on macOS. Some days it would work, often DNS didn't work and the VPN DNS would take over, or the VPN DNS would not get used when it was needed. I found myself connecting only when I really needed to, and disconnecting as soon as I could. Then I decided I could afford the modest fee for Viscosity - and I have not regretted it for a second. Easy to install, easy to set up (yes, you do need to read the instructions) and when our VPN server had a problem, I had the logs to help figure out what was going on. Initially I set up a TAP (L2 bridged) connection, and my macOS did give me a warning about "legacy system extensions" (See support.apple.com/en-us/HT210999) but once I allowed it, it worked just fine. We later moved the whole setup to a L3 routed (TUN) connection which did not require any legacy system extensions, and it still works perfectly - irrespective of screen savers or any other software.

Since it is not possible to prevent applications e.g. your-default-torrent-app from downloading when the VPN is not active, On my mac when the screen saver activates, the viscosity drops the VPN connection even though there is an active utorrent downloading. Scary, really scary.
