VERDICT

Should I use Cloudswit (Asterfusion Data Technologies)?

SONiC-Powered Turnkey Whitebox Switch Solution - cloudswit.ch

Depends. Buy if you run a data center or campus network with SONiC-literate engineers and want to escape Cisco/Juniper pricing. Skip if you need plug-and-play switching or published prices — everything is quote-only.

Confidence

Medium. Based on ~12 usable public sources; numerous On Cloudswift running-shoe results excluded as unrelated noise. No independent switch reviews found.

Gotchas - check before you buy

medium

Quote-based pricing means no way to benchmark against competitors before talking to sales

medium

NOS is subscription-licensed; recurring fees persist even after hardware is paid off

medium

Small community means slower troubleshooting outside vendor support channels

low

Search results are swamped by the identically named On Cloudswift shoe, complicating due diligence
