While a virtual machine does add security, virtual machine breakouts do exist, and VirtualBox has be on the receiving end of such exploits before. I get the feeling development on this product is abandoned. Except that they are actually using a very outdated version of VirtualBox from 2012, which is probably a bad idea for lack of security updates. So apparently it runs Firefox on Debian 6 Linux with SELinux inside a virtual machine running inside VirtualBox, on a host that must be Windows.Īs for how secure that is, for the most part, it's the same as running a browser inside a Linux VM in VirtualBox with a snapshot you roll back every time you want to reset. Configuration data of the browser can be stored persistently and are retained for restart.Reset to certified initial snapshot upon each start of the browser.Downloaded files are first scanned and then provided to userĬonfigurable security polic for copy & paste, download, upload and printing.No Flash, Java, or plugins required Browserling is powered by HTML5 and JavaScript. Browser execution takes place in separated virtual machine with own operating system Browsers are sandboxed and run in our infrastructure so you don't have to worry about getting infected with viruses or trojans.Comes with: VirtualBox 4.0.16, hardened Linux Debian 6 and SELinux and Firefox.It also has an input method for explicitly giving sandboxed code data it wouldnt otherwise be able to get. Can be used with Windows XP and Windows 7 I created a sandboxing library called jsandbox that uses web workers to sandbox evaluated code.From their product page, we can infer a lot about how their system works.
