| Privacy | One known XSS vulnerability (CVE-2024-44449) in onQ OS v6.0; no broader public vulnerability history found in the sources reviewed.⁴ | Mature enterprise security program, but multiple critical CVEs and a claimed data-theft campaign surfaced in 2025-2026.15 |
| Support quality | No direct support evidence found | Basic plan criticized; enterprise support costs extra |

| Biggest gotcha | XSS (CVE-2024-44449) disclosed in onQ OS v6.0 . confirm patch status before buying.⁴ | Billing surprises are the top complaint: one user paid £300/month for a single-table SQL DB |
