Browser Isolation

Definition of Browser Isolation

Browser isolation is a cybersecurity technique that segregates a user's browsing activity from their local machine and network. This is accomplished by running web sessions on a remote server, either in the cloud or a dedicated offsite location. Essentially, it's like putting a protective bubble around your internet use. When you click on a link or enter a website, instead of your computer directly accessing these potentially harmful sites, the isolated browser does it for you, streaming only the safe output to your screen.

Origin of Browser Isolation

The concept of browser isolation has been around for a while, but it gained significant attention as enterprises looked for more robust security solutions against web-based threats. Originally, the idea was to defend against the increasing sophistication of cyber-attacks that targeted the end-user through their web browser—one of the most commonly used software applications. The method was born out of necessity, with the early implementations focusing on the most at-risk users within an organization, such as those with access to highly sensitive data.

Practical Application of Browser Isolation

One of the most practical applications of browser isolation can be found in the financial sector. Banks and financial institutions use it to protect against data breaches and ensure that their employees can access critical systems without risking exposure to malicious sites. For instance, when an employee accesses their institution's database, browser isolation ensures that any malware present on a less secure site is unable to infiltrate the internal network. This practice is also used in education and healthcare, where information security is paramount.

Benefits of Browser Isolation

Embracing browser isolation brings a plethora of benefits. It significantly reduces the risk of malware infections since the actual browsing happens away from the user's device. There's also the advantage of preserving bandwidth because heavy content is filtered out before it reaches the end-user's network. Moreover, it provides a smoother browsing experience when dealing with untrusted or suspicious sites, as any malicious code is contained and destroyed before it can cause harm. For businesses, this means enhanced security, reduced downtime, and better compliance with data protection regulations.


Not significantly. While the process involves an additional step by routing the data through a different server, modern solutions are designed to minimize latency, offering a seamless browsing experience.

No, browser isolation is a complement to antivirus software. It adds an extra layer of protection specifically for web activity, while antivirus software provides a broader range of security features for your entire system.

Yes, businesses of all sizes and sectors can benefit from browser isolation, particularly those that handle sensitive information or are subject to stringent regulatory compliance regarding data protection.
