Mitigate risky web activity with Remote Browser Isolation.
Part of Versa SASE, Versa RBI moves the execution of a user’s browser activity from the client device to a remote server — hosted on-premises or in the cloud. This protects a user’s device against browser-based security exploits and provides a means of contained, secure Internet access.
As the user browses the public Internet, any type of risk such as malware or malicious links are sandboxed and isolated from the user’s physical endpoint and enterprise network. Therefore, any exploits or vulnerabilities on a web session are constrained to the virtual environment.
Every browser session runs in an isolated environment that prevents any compromise from infecting the user’s working environment. Attacks at the browser level are expected, but when using a remote browser, attacks can’t reach other systems and can’t persist. This removes the threat because sessions are reset after each use.
How RBI Protects your Organization’s Data
RBI also helps with data protection, especially in the case of unmanaged or untrusted devices being used to access confidential or sensitive information.
Instead of allowing the unmanaged devices to download the information/files, the system downloads the sensitive information to the remote/isolated browser instance. The unmanaged or untrusted devices only see a visual rendering of the data.
Deploying Versa Remote Browser Isolation.
Versa RBI can be implemented in two ways. One is as a primary means of protection, where it renders all sites using RBI, with other filtering (mainly site categorization) applied as needed. The other is as a feature of a traditional web proxy, where it renders sites selectively using RBI based on the site’s reputation. Here’s how that works:
- User sessions are scanned for risk based on URL filtering and categorization.
- Risky websites are rendered on a remote browser.
- Sanitized pages (primarily image files) are rendered on the user’s browser.
RBI takes a selective content disarm and reconstruction (CDR) approach to web browser sessions. Versa RBI operates in the following two ways:
- By rendering an image of a web page in the user’s browser using a plug-in or an HTML5 renderer
- By extracting readable information from a web page’s HTML and reconstructing it in the user’s browser
