Citrix Remote Browser Isolation vs Kasm Workspaces

Citrix Remote Browser Isolation separates web browsing from a user’s device to protect corporate networks from browser-based attacks and provide access to internet-hosted web applications. Users open web apps in a configured browser, while browsing data does not transfer directly between the website and the device. Published browsers support shared-passcode, authenticated, and unauthenticated external web apps. Administrators can set URL allow lists, control clipboard use, printing, kiosk mode, region failover, and client drive mapping, then monitor or disconnect active sessions. Optional activity logging records visited host names, access times, user identifiers, and allowlist status in the customer’s Azure Storage Account; uploads occur hourly rather than in real time. Cloud browsers run on VDAs, with Citrix Cloud managing security and patching. Session history and HTTP-request cache are deleted when sessions end, according to Citrix. Access requires an HTML5-compatible browser, with no downloadable client. Traffic uses TLS 1.2 only. Self-hosted workloads require a customer Azure subscription and specified Citrix and DaaS entitlements.

Kasm Workspaces provides virtual desktops, browser isolation, and application streaming through a workspace platform. It supports containerized sessions and virtual-machine workspaces, accessible through modern browsers without plugins, agents, or client installs. Deployment can be on-premises, in disconnected or air-gapped environments, across multiple clouds, or in hybrid architectures. Listed connectivity includes KasmVNC, VNC, SSH, and RDP. Administrators can apply group policies, role-based access controls, data-loss-prevention restrictions, and session controls. LDAP, SAML, and OIDC are supported authentication providers, and Kasm describes integrations with identity providers, security tools, infrastructure, operational workflows, and existing VDI, PAM, IAM, SIEM, and DLP initiatives. Kasm states SOC 2 Type II and CMMC Level 2 certifications, while noting that customer compliance depends on implementation and maintenance. Community is free for five concurrent sessions with no commercial use. Starter named-user licensing is priced on request; concurrent-session licensing is priced on request.
