Comparison
3CX vs Bitrix24
3CX and Bitrix24 both land on Depends.
Bitrix24
Depends
Confidence: High
Choose it if you want a genuinely free all-in-one suite and can absorb real setup complexity and a cluttered UI.
| Compare | 3CX | Bitrix24 |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | Cost-conscious SMBs with in-house IT | Budget-conscious teams wanting one tool for everything |
| Who it's not for | Orgs with no security staff to patch fast | Solo users or tiny teams that just need a contact list |
| Privacy | Signed desktop app compromised in a 2023 nation-state supply-chain attack; repeated CVEs and exposure alerts since.¹ | Multiple public CVEs since 2022 including several RCEs, plus a claimed 2023 hacktivist attack; acceptable only with disciplined patching. |
| Support quality | Users report poor vendor support | No support-quality evidence in reviewed sources |
| Public sentiment | Splits hard: fans cite price, features, and ease of use, while detractors cite poor support and security baggage. | Users praise the price and breadth but complain about a cluttered interface and weak segmentation.15 |
| Biggest gotcha | Licensed per simultaneous call, not per user . misestimate and calls block or you overpay | Guess: all-in-one design creates lock-in . migrating CRM, tasks, and files out later is painful. |
