| Compare | FreePBX | G2 |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | MSPs managing many client phone systems | B2B software buyers shortlisting tools |
| Who it's not for | Non-technical teams wanting plug-and-play phones | Vendors without five-figure budgets |
| Privacy | Multiple critical 2025 vulnerabilities, including actively exploited unauthenticated RCE; requires rapid patching and lockdown⁸ | No public security page found; UpGuard reports no phishing; G2's own DPA references a past data breach. |
| Support quality | Community forums; paid support is Sangoma-only | Trustpilot and BBB complaints about G2's service |
| Public sentiment | Users praise FreePBX's flexibility and free price but flag the security burden, paid module creep, and uneven support. | Buyers find G2 useful for breadth, but sentiment on G2's own service skews negative on Trustpilot and Redditors weigh it against Capterra and Trustpilot. |
| Biggest gotcha | August 2025 zero-day let attackers root unpatched, internet-facing servers; emergency patch required | Vendor contracts are negotiated and opaque; budget five figures annually before committing. |
