Remote Browser Isolation (RBI) and Enterprise Browsers are two technologies for securing the browser. While they each have their own benefits and advantages, there are also pitfalls to be aware of. In this blog post, we compare the two and show how to overcome the risks they pose.
Understanding Remote Browser Isolation (RBI)
Remote Browser Isolation (RBI) is a security measure that isolates web browsing activity from a user’s local network and endpoint devices. This is achieved by running the browsing sessions on remote servers instead of the user’s device. The user’s browser interacts with the remote server instead of the internet, and the server fetches and executes web content. The results are rendered and displayed back to the user, typically in the form of a clean, safe stream of data (e.g., HTML, images, and JavaScript).
RBI ensures that any malicious content encountered when browsing is contained and does not reach the user’s endpoint. This enables RBI to effectively prevent potential threats, such as malware, ransomware, and phishing attacks from impacting local systems.
How RBI Works
With RBI, content is processed and rendered on remote servers. This approach ensures that even if the content is malicious, it cannot harm the user’s device.
Here’s how it works:
- When a user attempts to visit a website, their browser sends a request to a remote isolation server rather than directly accessing the internet.
- The isolation server receives the request and acts as a middleperson. It fetches the website’s content, including HTML, JavaScript, images, and other resources.
- The fetched content is executed and rendered on the isolation server. This means any scripts or active content on the web page run in a secure, isolated environment away from the user’s device.
- After rendering the content, the isolation server transforms it into a safe, sanitized data stream. This could be in the form of a secure visual representation (like a remote desktop session) or a clean, simplified data format such as HTML5 or SVG.
- The sanitized stream is sent back to the user’s browser. The browser then displays the content as if it were being accessed directly from the internet. This can be achieved through various techniques, such as pixel pushing, which sends only the visual elements of a web session to the user’s browser, or DOM mirroring, where the Document Object Model (DOM) of the web page is reconstructed locally, but scripts and potential threats are executed remotely.
- The user interacts with this content through a secure stream, viewing a safe visual representation of the web page.
- Users can click, type, scroll, and interact with the web page seamlessly. Any interaction inputs from the user (like clicking a link or submitting a form) are sent back to the isolation server, which processes them and updates the displayed content accordingly.
- The isolation server continuously monitors the web session, ensuring that any potentially harmful content remains contained. If any malicious behavior is detected, it is neutralized within the isolated environment, preventing it from reaching the user’s device.
Key Advantages of RBI
- Superior Threat Protection: RBI effectively neutralizes threats by keeping all web content in a remote environment. This isolation ensures that malicious code, including malware, ransomware, or phishing attempts, remains confined to the remote server and never reaches the user’s endpoint.
- Compliance Assurance: RBI facilitates stringent data protection and policy enforcement. Administrators can monitor user activities and implement security policies to control access to potentially harmful websites. This ensures compliance with industry standards and helps safeguard sensitive data.
- User-Friendly Integration: RBIs are compatible with existing browsers, ensuring a seamless and uninterrupted browsing experience for users (though probably not for IT). This is unlike some security solutions that may require specialized software or disrupt normal operations. Such a user-friendly approach means employees can continue their work without noticeable changes, promoting both security and productivity.
Enterprise Browsers: Customized Security Solutions
Enterprise browsers are specialized web browsers designed specifically for corporate use. They offer enhanced security features, like policy enforcement, URL filtering, malware protection, and encryption. This ensures safe and efficient web browsing for employees while maintaining strict compliance and control over web access and data. In addition, they provide centralized management capabilities and productivity tools, which align with IT and business needs.
