A concise summary of the risk, the deadline, and the six actions your team needs to take now.
IGEL OS 11 reaches End of Maintenance. After this date: no security patches, no updates, no Secure Boot certificates — on any device still running OS 11.
IGEL OS 11 has been the standard endpoint operating system for organisations running VDI, DaaS, and cloud workspaces on thin clients and repurposed PCs. That support is now ending. After 30 June 2026, IGEL will issue no further patches, security fixes, or Secure Boot certificates for OS 11 — leaving any device still running it exposed and unmanaged.
There is also an immediate hardware risk. Microsoft’s October 2025 Secure Boot revocation update means that if a BIOS/UEFI firmware update is applied to an IGEL endpoint running an older OS version, the device may be unable to boot.
Unpatched endpoints become a persistent vulnerability at the access layer of your cloud or VDI environment.
BIOS updates applied before OS migration can render devices unbootable — an outage risk if not managed carefully.
OS 11 perpetual licences reached end of renewal in December 2025. Continuing to run OS 11 or moving to OS 12 both require transition to IGEL’s subscription model (Platform Access Subscription). Engage your IGEL partner now to understand your position.
IGEL OS 12 is a fundamentally different product — not an incremental update. Introduced as part of the IGEL COSMOS platform in April 2023, it separates the base OS from its applications entirely, allowing apps like Citrix Workspace, Zoom, and VMware Horizon to be updated independently via the IGEL App Portal without touching the underlying OS.
Since launch, IGEL has continued to invest in the platform, most notably through the IGEL Adaptive Secure Desktop™ — which delivers persona-driven, role-based workspaces enforcing Zero Trust principles at every login, tailoring applications and data access to the individual user. OS 12 is the required foundation for these capabilities.
Importantly, the management layer — UMS 12 — supports both OS 11 and OS 12 devices simultaneously, making a phased migration operationally viable without forcing a disruptive cutover.
Organisations that move to OS 12 now gain access to the full IGEL roadmap: Adaptive Secure Desktop, Zero Trust enforcement, improved endpoint telemetry, and faster application delivery. This is not just a compliance exercise — it’s a platform upgrade.

Identify all devices on OS 11, current version numbers, and any below v11.10.410 — those face immediate Secure Boot risk if BIOS updates are applied.

The deadline is fixed. The licensing clock has already started. And the profile rebuild work is more involved than a standard OS upgrade — it requires dedicated planning time. Organisations that begin now have a manageable project ahead of them. With the 30 June 2026 deadline just weeks away, those yet to start are already in a difficult position — the time for comfortable planning has passed.
