RBI, VDI, WAF or VPN: Comparison of secure remote access solutions

RBI, VDI, WAF or VPN: Comparison of secure remote access solutions

Enabling secure access to your sensitive business applications, especially in mobility, is a growing concern for businesses. With today's technology landscape, choosing the right solution can seem like a daunting task between VPN, VDI, RBI, dedicated PCs, and others. Comparison.

VDI, RBI, WAF, and VPN: the differences

Using a VPN (Virtual Private Network), while effective, can be costly both in terms of acquisition and deployment. This is without offering complete protection against the risks associated with the remote user's workstation. On the other hand, the VDI (Virtual Desktop Isolation), while it reduces concerns about remote desktop security, requires significant server power. This need comes from the provision of a complete work environment to allow the user to have an Internet browser in his session. As a result, VDI has a considerable attack surface. The WAF (Web Application Firewall), on the other hand, based on the detection of signatures and behaviors, cannot but intercept certain zero-day attacks or unknown threats, unlike the RBI (Remote Browser Isolation) that isolates potentially malicious content.

RBI, the future of cybersecurity

With the RBI, access to your applications is via an isolated virtual browser, setting up a protocol break between the remote station and the resource accessed, thus considerably increasing the level of security. This process also reduces the need to authorize numerous incoming flows, thus simplifying network authorization management:

  • Granular control : Businesses have complete control over user interactions, such as copy/paste, downloads, screen prints, and access to external devices.
  • API protection : Potential attacks related to the exposure of your APIs are no longer possible, as calls can only be made via the isolated browser.
One of the main advantages of RBI is that it almost entirely eliminates the need to worry about the security level of the remote user's workstation.

While each solution has its own benefits, RBI combines the best of all worlds: solid security, a smooth user experience, a minimal attack surface, and unprecedented ease of deployment. For businesses that care about cybersecurity, it's time to seriously consider the potential of RBI to meet the needs of today and tomorrow.
