Organizations securing access to sensitive systems often find themselves operating three separate technology stacks: a VPN for network access, virtual desktop infrastructure (VDI) for isolated desktops, and remote browser isolation (RBI) for web-based threats. Each comes with its own infrastructure, management console, licensing model, and operational overhead.
Kasm Workspaces was built to simplify that architecture by delivering secure browser, application, and desktop access from a single platform governed by one policy engine and one audit trail. With its integration with Proxmox Virtual Environment (Proxmox VE), organizations can deploy Kasm Workspaces on a modern, open-source virtualization platform while maintaining centralized control over secure workspace delivery.
Rethinking Secure Access Beyond VPN and Traditional VDI
Kasm Workspaces is a platform for delivering secure, policy-controlled browsers, applications, and desktops through a web browser. Rather than extending network-level trust to endpoints, Kasm streams business applications and desktops as pixels. Sensitive data remains inside the organization's environment instead of residing on user devices.
Instead of deploying and maintaining separate VPN, VDI, and remote browser isolation products, organizations can manage secure access from a single control plane with centralized policy enforcement and auditing.
In practice, organizations can deploy Kasm Workspaces quickly, integrate it with existing identity providers and security tooling, and provision secure workspaces in minutes. User sessions execute in isolated containers or virtual machines under organizational control, and can be destroyed automatically when sessions end according to administrative policy. This minimizes persistent data on endpoints while supporting Zero Trust access architectures.
How Kasm Workspaces Integrates with Proxmox VE
While Kasm Workspaces delivers secure workspaces, it relies on underlying infrastructure to host those sessions - Proxmox VE provides that virtualization layer. Built on open-source technologies including KVM and Linux Containers (LXC), Proxmox VE manages virtual machines, storage, networking, clustering, and high availability from a unified management platform.
Kasm Workspaces integrates with the Proxmox VE API to automate the provisioning and lifecycle management of workspace infrastructure. As user demand increases, Kasm can automatically provision additional worker virtual machines on Proxmox VE. As demand decreases, those resources can be retired automatically, allowing organizations to align infrastructure consumption with real-time usage.
This division of responsibilities creates a clear architecture:
- Proxmox VE provides the virtualization infrastructure, including compute, storage, networking, and virtual machine management.
- Kasm Workspaces provides secure workspace orchestration, policy enforcement, session management, and browser, desktop, and application delivery.
Together, the platforms provide an integrated solution for delivering secure workspaces on an open-source virtualization foundation.
Proven Outcomes Across Demanding Environments
Kasm Workspaces is trusted by organizations with rigorous security, compliance, and operational requirements, including enterprise and government environments with demanding access control requirements.
One federal agency has been operating Kasm Workspaces on Proxmox VE for more than a year to deliver browser-based Linux desktop sessions across multiple secure network segments. More recently, the organization expanded the deployment to support Windows desktop sessions using Kasm's autoscaling capabilities integrated with Proxmox VE.
This architecture allows the agency to provide users with the Windows applications they require while minimizing persistent desktop infrastructure and making efficient use of available compute resources.
The deployment demonstrates how organizations can combine secure workspace delivery with an open-source virtualization platform to meet demanding operational and security requirements.
Where Kasm Fits Within a Zero Trust Architecture
Kasm Workspaces can simplify secure access by consolidating browser isolation, application delivery, and desktop delivery into a single platform. Running Kasm Workspaces on Proxmox VE provides organizations with an open-source virtualization platform for hosting those workloads.
However, neither platform replaces identity providers, endpoint security, or broader Zero Trust governance. Organizations should continue integrating identity, device posture, monitoring, logging, and security operations capabilities into their overall architecture. Kasm Workspaces is designed to integrate with these existing technologies rather than replace them.
Simplifying Secure Access Without Compromising Control
For years, organizations have accepted a trade-off between broad network access that is difficult to secure and multiple point products that each solve only part of the secure access problem.
Kasm Workspaces offers a different approach by delivering browsers, applications, and desktops through a unified policy engine and audit trail, while Proxmox VE provides the virtualization infrastructure that hosts those workloads. Together, they enable organizations to simplify secure workspace delivery without requiring proprietary virtualization platforms underneath.
As organizations continue modernizing Zero Trust architectures, combining Kasm Workspaces with Proxmox VE provides a flexible deployment option that reduces infrastructure complexity while maintaining the security and operational controls required by enterprise and government environments.
About Kasm Workspaces
Kasm Technologies delivers a modern platform for secure browser, desktop, and application access. Kasm Workspaces streams browsers, desktops, and applications directly to users through ephemeral, policy-controlled sessions, helping organizations reduce the complexity of traditional secure access architectures while supporting Zero Trust principles.
