Benefits Of Remote Browser Isolation & Why It Is Important?

In this blog, we will discuss the Benefits of Remote Browser Isolation, how it works, and how it improves cybersecurity by phishing and malware attempts.

What Is Remote Browser Isolation?

Remote browser isolation (RBI) is a web security approach that removes online threats by hosting users’ web browsing sessions on a remote server instead of their endpoint device. To lessen its attack surface, RBI isolates online content from the user’s device. The endpoint gets a pixel-based stream of a webpage or application in place of the current content. The user experience cannot be impacted by hidden malicious code.

When a user encounters dangerous web content, RBI, also known as web isolation, isolates the environment and provides a cloud-hosted representation of the content. RBI stops malware that is concealed in content from getting to an endpoint or spreading across a network by redirecting web browsing activity to a cloud domain without downloading the material. In this approach, RBI enhances other crucial cybersecurity activities by offering efficient defense against known and undiscovered threats.

How remote browser isolation Works?

  • A user attempts to see potentially harmful online information.
  • The software creates an isolated browser session after evaluating the request against predefined policies.
  • The platform loads the material onto the isolated, remote browser after connecting to it.
  • The end user’s native browser receives rendered web content as pixels over an HTML5 canvas.

What Other Kinds of Browser Isolation Exist?

Three fundamental categories of browser isolation technologies exist:

  • A cloud-hosted sandbox, which is a distinct testing environment from an organization’s internal environment, is where remote browser isolation operates.
  • Similar to RBI, on-premises browser isolation is hosted as a component of an organization’s own IT infrastructure.
  • Client-side local browser isolation deletes browsing data at the end of sessions and operates on a user’s endpoint in a virtualized sandbox.

Why Is Browser Isolation So Important?

More and more of your employees work is being done online as your data and apps are moving from your data center to the cloud. They may frequently be linked virtually all the time. They may remain prolific as a result, but there is a danger.

Phishing and other cyberattacks use a user’s online browser to find their targets. They also use browser-based trojans, clickbait that might lead to dangerous information, and malicious advertisements. Once a browser is linked to a website, it may provide hackers with unrestricted access to a user’s computer and, eventually, your network.

You can attempt to ban high-risk websites using a firewall, but an allow list will annoy your users with limitations, and a blocklist won’t take into consideration unexpected risks. The cloud and the open internet of today weren’t intended for traditional network security procedures. Remote browser isolation is therefore necessary.

Network security is not what RBI is. It guarantees that ransomware and other malware cannot infiltrate your network through compromised websites by putting a user’s browser session in a separate cloud sandbox.

Benefits of Remote Browser Isolation

  • Remote browser isolation can be used to make online browsing safer.
  • Isolates people from online programs to provide a safe rendering of web content, enabling safe access to potentially harmful material without needing an endpoint agent on each device.
  • Shields private information from deliberate assaults concealed in downloaded web material, vulnerable plugins, and webpages, all of which can cause data loss.
  • Eliminates the possibility of data exfiltration by stopping websites from breaching endpoints, even when the browser includes malicious plugins or security flaws.
  • Permits more open internet policies, allowing you to decrease risk, simplify restrictions, and provide people more freedom to use the internet.

Challenges of Remote Browser Isolation

Numerous remote browser isolation options have disadvantages despite their advantages. When a large number of browser sessions are sandboxed and streamed to consumers, it usually leads to:

  • A bad user experience will arise from the longer lag time required for session data to go between the user endpoint and the sandbox. Naturally, complex security stacks only make the situation worse.
  • A significant amount of bandwidth is needed for streaming pixels, and if your infrastructure isn’t designed to handle it, it may quickly get overloaded.
  • Expensive It takes a lot of processing power to stream encrypted video information, and if you’re paying for the additional resources, it might get costly.
  • The demands of today’s dispersed workforce can never be met by RBI solutions that rely on traditional network architecture, transport data over great distances, and use hardware with restricted capacity. Effective RBI therefore works well with a cloud-native zero trust strategy.

How Can a Zero Trust Security Architecture Use Remote Browser Isolation?

The foundation of zero trust is the idea that all user and network behavior ought to be untrusted by default. With the correct technology, your company may employ RBI’s zero trust strategy to isolate users from sessions and prevent both malicious and unintentional data leaks.

The RBI’s concept of zero trust is expanded to include everything consumers do on the internet, as well as in SaaS and private apps. You don’t have to pick between speed and security since native integration with a full cloud-delivered security stack allows you infinite growth and flexibility. Additionally, only one vendor trusted by over 40% of the Fortune 500 offers it with the strength of the biggest security cloud in the world.
