Security posture3

One known XSS in onQ OS v6.0

Pros

  • G2 reviewer reports nearly 10 years of continuous use²
  • MSP reports a customer running it long-term³
  • Healthcare case studies published on vendor site⁷

Cons

  • Known XSS vulnerability in onQ OS v6.0⁴

  • No public pricing found; sales-led purchase likely¹

Gotchas

  • highXSS (CVE-2024-44449) disclosed in onQ OS v6.0 — confirm patch status before buying.⁴
  • mediumGuess: appliance/subscription pricing is quote-based; expect vendor demos and negotiation.¹
  • mediumSearch results conflate several unrelated 'Quorum' companies (cologne, public-affairs software) — vet reviews carefully.⁹
  • lowCrawler found no security page at — vendor security documentation is thin.⁶

Best for

  • Teams needing automated DR testing
  • Ransomware-wary SMBs
