Discover how Zscaler Browser Isolation can improve your business's security.
Zscaler Cloud Browser Isolation (CBI) is a technology designed to create a secure and isolated browsing environment for users. This approach ensures that every web session is protected from potential threats.
Traditionally web content is rendered directly on the user's device, which can expose the endpoint to various risks, including malware and other malicious content. Zscaler's CBI technology streams only the pixels of the rendered web pages to the user's browser. The rendering is done securely on a Zscaler server. This means that the actual web content never reaches the user's device, significantly reducing the risk of infection and enhancing overall security.
Zscaler offers this advanced browser isolation feature as part of its two flagship products: Zscaler Internet Access (ZIA) and Zscaler Private Access (ZPA). ZIA provides secure internet access by inspecting all traffic, blocking threats, and ensuring compliance with organizational policies. ZPA, on the other hand, offers secure remote access to internal applications. Together, these products leverage Zscaler's Cloud Browser Isolation technology to deliver a security solution that protects users from web-based threats while maintaining a seamless and efficient browsing experience. Whether accessing the internet or internal applications, users can rely on Zscaler to provide robust security and peace of mind.
The main benefit of Zscaler Cloud Browser Isolation is that it can block most possible exploits because it streams merely the pixels-the actual code is streamed only to the server. Attacks that browser isolation can prevent are for example watering hole attacks where users are baited into visiting malicious websites that are designed to compromise an operating system on a laptop.
Another key benefit of this technology is its ability to block clipboard access and restrict file download and upload capabilities for websites. This functionality plays a crucial role in enhancing security and preventing data breaches. Firstly, blocking clipboard access is essential for preventing the unauthorised transfer of sensitive information. The clipboard is often used to copy and paste data between applications, which can inadvertently lead to the exposure of confidential information. By restricting clipboard access, Zscaler CBI ensures that sensitive data cannot be copied from the isolated browsing session to other applications on the user's device. This can prevent users from imputing credentials to a phishing page or sharing other sensitiv information.
Secondly, restricting file download and upload capabilities is a critical measure to safeguard endpoints from malware and other malicious content. When users download files from the internet, there is always a risk that these files could contain harmful software that can compromise the security of the device.
If the users need to input text for upload files to the websites, while still isolated, the Isolation Profile can allow those actions. The company is still protected from the loss of sensitiv information with Zscalers Data Loss Prevention Feature.
If the download in isolation is necessary the downloaded files are scanned for malware by the Zscaler Sandbox. Moreover, these restrictions help organisations enforce their security policies more effectively. By controlling clipboard access and file transfer capabilities, IT administrators can ensure that users adhere to the organization's data protection policies. This is particularly important in regulated industries, where strict compliance with data security standards is mandatory.
CBI still offers more features that can increase security, usability and compliance. Sometimes the downloaded of a file is not needed because it can be rendered in the browser while still being isolated. Allowing users to view and interact with documents such as Word, Excel, and PowerPoint files directly within the isolated browsing environment. This feature eliminates the need to download these files to the endpoint, thereby reducing the risk of malware infections. Users can safely view and edit documents without compromising the security of their devices.
Persistent cookies allow session data to be retained in the next sessions. This feature is particularly useful for maintaining user preferences and login states, ensuring usability without compromising security. By persisting cookies, users can continue their work without needing to re-authenticate or reconfigure settings, while still benefiting from the isolation and protection provided by CBI.
Webpage translation can be a valuable tool for users who need to access content in different languages. Zscaler CBI can be configured to either allow or block the translation of web pages. Allowing translation can enhance accessibility and usability for international teams, enabling them to understand and interact with content in their preferred language. Conversely, blocking translation can prevent potential security risks associated with third-party translation services that might mishandle or expose sensitive information.
Zscaler Browser Isolation is particularly useful for websites that are untrusted, but should not be blocked. These sites may not be explicitly malicious but can still pose potential risks, since they are unknown to the organisation. A big benefit of using the Zscaler solutions are that Zscaler classifies the websites into different categories, that can be used in policies. Categories that contain recently registered domains, can be isolated or blocked. By isolating these sessions, businesses can safely allow access without compromising security.
Moreover, browser isolation is beneficial for accessing suspicious websites that need to be used for research or other purposes, providing a safety access to potential threats and making tools such as browserling unnecessary. The access policies can be granular only allowing users that need access to those website the access though browser isolation.
Zscaler is a solution that integrates browser isolation into its individual platforms and combines it with other security solutions such as data loss prevention or their sandbox. The solution itself is scalable and can be configured differently to support various companies or organizations, while still providing business continuity and minimal disruption. This flexibility ensures that Zscaler can meet the unique needs of different use cases.
The solution is designed to be user-friendly, ensuring that employees can continue their work without significant changes to their workflow.
Additionally, Zscaler's browser isolation can be configured to persist cookies across sessions, allow or block webpage translations, sanitize downloaded files, and render office files directly in the browser. These features enhance security and compliance, ensuring that organizations can protect their data and meet regulatory requirements. For example, persisting cookies helps maintain user sessions, while file sanitization ensures that any downloaded content is free from malware.
Overall, Zscaler Browser Isolation provides a comprehensive solution that enhances security, supports compliance, and ensures business continuity. By leveraging these advanced features, organizations can protect their users and data from web-based threats while maintaining a seamless and efficient browsing experience.
