Browser isolation is a cybersecurity model that aims to physically isolate an internet users browsing activity away from their local networks and infrastructure. It is a way to isolate web browsing hosts and other high-risk behaviors away from mission-critical data and infrastructure. Browser isolation technologies approach this model in different ways, but they all seek to achieve the same goal: effective isolation of the web browser and a users browsing activity as a method of securing web browsers from browser-based security exploits, as well as web-borne threats such as ransomware and other malware.

Browser isolation typically leverages virtualization or containerization technology to isolate the users web browsing activity away from the endpoint device, significantly reducing the attack surface for rogue links and files. Browser isolation is a zero-trust approach that does not rely on filtering content based on known threat patterns or signatures, unlike traditional web security approaches such as antivirus software and secure web gateways.

Browser isolation is a technology that contains web browsing activity within an isolated environment, like a virtual machine or sandbox. This isolation may occur locally on the computer or remotely on a server. Browser isolation provides additional security for devices and networks when using a web browser and is a strong deterrent to cybercriminals, significantly reducing the risk of malware infiltration. It builds walls around network activity, creating an isolated environment that is sealed off from outside attempts at infiltration, specifically malware. Essentially, it keeps internet activity separate from a users actual device by putting it in a protected, virtual environment. If a user comes across a malware threat, the malware is held at bay outside this virtual environment and never actually makes it to their computer or device.

Remote browser isolation (RBI) is an advanced cybersecurity technique that provides an additional layer of protection for users and organizations. RBI is a web security technology that isolates users and endpoints from all active web content, giving security teams peace of mind with the knowledge that their enterprise is protected from zero-day vulnerabilities, ransomware, unsanctioned plugins, and other sophisticated threats.
