Legitimacy and reliability of iVisa for Vietnam business visa applications

Hi everyone, I am currently planning a business trip to Vietnam and looking at my visa options to ensure a bug-free entry.

I came across iVisa while searching for application portals. Logic check: Is iVisa directly connected to the Vietnamese government agencies, or is it a private third-party service? I want to make sure the service is legit for a business visa application and not a scam. I am pushing to prod soon and need to verify if their “expedited” processing is optimized code or just marketing. Any input on the reliability would be appreciated.

Realizing this is commonly confused with the official E-visa portal…

Has anyone from the Asian region used key features of iVisa for a highly time-sensitive business trip?

I wish to document a previous experience with a similar third-party visa intermediary to add context.
