| Verdict | Depends | Depends |
| Best for | Mid-size and large manufacturers | Hardware startups |
| Who it's not for | Startups and small teams | Software-only teams chasing SBOM compliance . name confusion, wrong category |
| Privacy | Active exploitation: Cl0p ransomware stole data via Windchill flaw CVE-2026-12569; CISA added it to KEV . patch immediately.³ | No known public vulnerabilities found in the sources reviewed. |
| Support quality | Public Reddit complaints about support responsiveness | No direct evidence in sources |
| Public sentiment | Ratings are solid, but Reddit threads flag steep pricing and weak customer support.¹ | Reviews praise simplicity and CAD fit, but much visible praise is vendor-published; Reddit threads are mostly inquiries, not complaints.⁹ |
| Biggest gotcha | Cl0p exploited Windchill servers to steal data from 40+ orgs . patch immediately if running Windchill² | Bills combine seats with data-record counts; growing usage raises costs beyond headcount16 |
