Managed workspace size catalog

Citrix SecurSpaces Flex now uses a Citrix-managed workspace size catalog. Citrix publishes the available workspace size tiers and their versions, and Flex deployments reconcile that catalog during platform updates.

This release adds lifecycle status for managed tier versions. Administrators can see current, older, and retired tier versions, keep organization and project availability settings, and update affected workspaces to the current version of the same tier.

Key capabilities include:

  • Managed Light, Medium, and Heavy workspace size tiers with version status.
  • Organization and project availability controls that remain available to administrators.
  • Workspace update prompts when a workspace uses an older managed tier version.
  • Bulk tier-version updates that move workspaces to the current version of the same tier.
  • Retired tier versions that are hidden from new workspace creation while existing workspaces remain visible.

For more information, see SecurSpaces Flex workspace templates.

Audit and stable managed tier identifiers

Managed workspace size tiers now provide a clearer operating record. When an administrator enables or disables a managed tier, or applies a bulk update to move workspaces to the current tier version, SecurSpaces records the successful action in the audit log with the actor, time, and result.

Citrix can also pin the identifier for a managed tier version in deployment values. This keeps the same managed tier version identifier across Flex tenants, while existing deployments without a pinned value continue to receive a generated identifier.

General Availability: Citrix SecurSpaces Flex

Citrix SecurSpaces Flex is now generally available as a Citrix-managed service within Citrix Platform Flex that delivers secure Linux workspaces for development teams. Delivered through Citrix Cloud, this service provides hosted developer environments with no customer infrastructure to stand up or maintain. In this release, Citrix SecurSpaces Flex is applicable only to Azure environments. For more information, see Citrix SecurSpaces Flex overview.

New and enhanced features

  • Citrix-managed control plane — Citrix operates the Azure Kubernetes Service (AKS) and Azure Cosmos DB infrastructure.
  • Workspace sizing by persona — Light (2 vCPU / 8 GB RAM), Medium (4 vCPU / 16 GB RAM), and Heavy (8 vCPU / 32 GB RAM), each mapped to a published Platform Flex credit rate.
  • Decoupled workspace size and template — A single workspace template can be paired with any compute profile on demand.
  • Multi-region support — A primary Azure region is provisioned at deployment time, and secondary regions can be added later by your Citrix team.
  • Version management — Citrix manages version updates for your environment, including scheduling of maintenance windows.
  • Network connectivity — Connect workspaces to customer-owned systems via Azure vNET peering or VPN gateway.
  • Native DLP, RBAC, and audit logging — Built-in controls for data loss prevention, access governance, and compliance.
  • Sandboxed AI agent support — AI coding agents run inside workspaces under the same control plane and policy framework as human developer sessions.
  • Platform Flex credit model — Citrix SecurSpaces Flex credits draw from the same pool as Citrix DaaS Flex, with no separate procurement cycle.
