What is browser isolation?
In short, when you click on a web site or link, that information does not load on your physical computer but on another, isolated computer that is completely separate from your device and network(s).
Browser isolation is a key component of a Zero Trust security model, in which no user, application, or website is trusted by default. In our SaaS-based and cloud-first world the browser the most common attack vector for the bad guys.
Why do organizations use browser isolation?
The global annual cost of cybercrime is predicted to reach $8 trillion annually in 2023.
The Internet has become incredibly important to modern business operations. The most important resource of today's modern workforce. It used to be that business processes took place mostly within an internal corporate network, but that has long since stopped being the case. Instead employees regularly access websites and web applications to do their work (and to perform personal tasks), and they do so through a browser.
Just as firewalls and network access control helped stop attacks directed at internal networks, browser isolation helps stop attacks directed at the browser.
Visiting websites and using web applications involves a web browser loading content and code from remote, untrusted sources (e.g. faraway web servers), then executing that code on a user's device. From a security perspective, this makes browsing the web a fairly dangerous activity and the source . Browser isolation instead loads and executes code far away from users, insulating them and the networks they connect to from the risks — similar to how using robots to perform certain dangerous tasks within a factory can keep the factory workers safer.
