Third-party support
for VMware
Keep the VMware you already paid for —secure and up to date— without renewing with Broadcom or migrating on someone else's schedule. You set the timeline: we support you if you stay on your current version and also if you migrate to Proxmox, OpenStack or VMware's latest.
The savings stay in your business and your team.

Failover with no impact on production. VM replication.
ActiveWhat we do, exactly
In-house engineers. No escalation to someone who doesn't know your installation.
Continuous monitoring of the NVD and vendor advisories. A mitigation plan in under 24h for CVSS ≥ 9 vulnerabilities, without depending on the vendor's portal.
P1 and P2 with contractual SLA. Response in under 1 hour for a full production outage.
Hardening of ESXi, vCenter and the perimeter network. Attack-surface reduction. Periodic configuration audits with a documented report.
Applicable pre-EOL patches and compensating mitigations post-EOL. Advanced configuration of HA, DRS and networking.
We put Proxmox VE, OpenStack and Broadcom's own VCF on the table, with their strengths and their real costs. No deadline pressure: you decide the timeline once the technical and financial evaluation is ready.
Response times
Full hypervisor outage, loss of access to vCenter or datastore corruption.
Performance degradation or component failure with a workaround available.
Architecture reviews, hardening and proactive recommendations.
SLA and penalties set out by contract.

Frequently asked questions
Yes. With a perpetual license you are entitled to run your version of VMware indefinitely: the license does not expire when Broadcom support ends. What you stop receiving are new patches and access to the technical portal. SIXE's third-party VMware support fills that gap —compensating patching, CVE response and incident resolution— with no active Broadcom contract and keeping your stable version.
Patches released before the end of general support (Oct 2, 2025) remain applicable. For later CVEs, SIXE applies compensating hardening: security configurations, firewall rules and network segmentation. For VMware 8 still in support, SIXE manages Broadcom's patches on your behalf.
No. It makes sense from environments with 3–4 ESXi hosts up to infrastructures with dozens of nodes. Broadcom requires a minimum of 72 cores per VCF bundle — we size the cost to your real environment.
Yes, subject to conditions. To reactivate official Broadcom support, a license audit is likely to be required. SIXE helps you assess those conditions before you make any decision and plans the service so that moving back stays an option.
Yes. We evaluate Proxmox VE, OpenStack or Broadcom's own VCF together with you, with proofs of concept where needed, and we support you through the migration. You decide the timeline once the technical and financial evaluation is ready, with no deadline pressure.
An assessment of your VMware environment
We review your VMware version, host count and license status, and calculate your real savings scenario compared with Broadcom. No commitment.
