Introduction: What Was the Citrix XenApp Plugin? In the evolution of enterprise IT, few tools have bridged the gap between legacy on-premise infrastructure and remote accessibility quite like the Citrix XenApp Plugin .

Its singular mission: to seamlessly connect a local client to applications published on a remote Citrix XenApp server farm (formerly known as WinFrame, MetaFrame, or Presentation Server). citrix xenapp plugin
If you are maintaining a legacy XenApp farm, upgrade to the Citrix Workspace app immediately. The old plugin has unpatched vulnerabilities (CVE-2018-15941, etc.) and lacks TLS 1.2 support. Your infrastructure is one security scan away from a critical finding. | Era | Name | Key Feature |
