|---|---|---|
| Verdict | Depends | Depends |
| Best for | Homelabbers and self-hosters | Microsoft-stack enterprises (AD, M365 shops) |
| Who it's not for | Teams without Linux sysadmin skills | Solo devs hosting one site or app |
| Privacy | Active CVE history . including auth-bypass issues exploited in the wild; prompt patching and hardening required.⁷ | Mature enterprise security program, but multiple critical CVEs and a claimed data-theft campaign surfaced in 2025-2026. |
| Support quality | No direct support-quality evidence found. | Basic plan criticized; enterprise support costs extra |
| Public sentiment | Users praise stability, clustering/HA, and value versus VMware, while griping about per-socket subscription costs and the Linux expertise required. | Users praise Azure's scale and Microsoft integration but repeatedly complain about unpredictable billing and a punishing learning curve.16 |
| Biggest gotcha | Auth-bypass CVEs had public PoCs and in-the-wild exploitation; patch the management interface fast⁷ | Billing surprises are the top complaint: one user paid £300/month for a single-table SQL DB |
