| Compare | ||
|---|---|---|
| Verdict | Depends | Worth it |
| Best for | Banks and trading desks | Individual stock researchers |
| Who it's not for | Startups and small businesses | Casual investors who check holdings a few times a year . broker apps suffice |
| Privacy | Troubled: hackers leaked 5.3M World-Check records (2024); Workspace outage and worldwide service disruptions also reported.³ | SOC 2 compliant; public trust center and vulnerability disclosure program; no known public vulnerabilities found. |
| Support quality | Public outages during market hours | No supporting evidence in sources. |
| Public sentiment | Customer reviews are scarce; employee reviews are mixed . 67-68% recommend LSEG on Glassdoor, with titles ranging from 'Good company' to 'Toxic but great'. | Users rate Koyfin 4.8/5 on G2, praising custom dashboards and market coverage, though some report limitations.15 |
| Biggest gotcha | Pricing is opaque enterprise contracts; expect sales negotiation and no self-serve trial | Koyfin discontinued its Pro plan and migrated subscribers . verify current tier features before paying annually.14 |
